Description

Handle leukocytic method, leukocyte compositions and application method thereof
The reference of relevant application
The application requires the right of priority of the U.S. Provisional Patent Application series number 60/053,599 of application on July 21st, 1997.
Invention field
The present invention relates to breed but the cell composition of reservation function, and these preparation of compositions methods and applications.More particularly, the present invention relates to prepare the propagation that is used to transfer and suppress leukocytic method.
Background of invention
Implement the multiple pernicious and non-malignant hematologic disease of bone marrow transplantation (BMT) treatment, comprise leukemia, multiple myeloma, lymphoma, anaemia and immunodeficient disease, as severe severe combined immunodeficiency (SCTD), WAS and aplastic anemia.
Leukemia is the malignant tumour of hemopoietic tissue.These tumours can be divided into two kinds of main types: chronic and acute.Acute leukemia (for example is characterised in that undifferentiated cell colony, acute lymphoblastic leukemia (or " ALL ") and acute myelogenous leukemia (or " AML ")), and chronic leukemia shows more sophisticated morphology (for example, chronic granulocytic leukemia (or " CML ") and lymphocytic leukemia (or " CLL ")) usually.There is the new leukemia case of about 25700 examples nineteen ninety-five in the U.S., and wherein about 4500 examples are CML.The U.S. diagnosed out the new CML case of about 7000 examples in 1996, and wherein about 30% finally accepts allosome BMT (leukemia association: leukemia association website, 1997).Estimate that about 50% BMT patient suffers leukemic recurrence.
The general objects of leukemia treating is to suppress the propagation of abnormal morphology, and recovers " normally " hemopoietic in the marrow.Treatment plan can comprise the combination of chemotherapy, radiotherapy and bone marrow transplantation.In " genus " allogeneic bone marrow transplantation (allosome BMT) scheme, at first give the chemoluminescence treatment of leukaemic's severe bone marrow depression dosage.This treatment stage is used for eradicating all leukemia cells and my late grandfather thereof.After suppressing pathologic hematopoiesis physiology, adiaphorous marrow on the function is replaced with the anosis stem cell of allogeneic.Under top condition, the marrow of transplanting is beneficial to the recovery of normal polyclone hematopoiesis propagation.The improvement of disease control also depends on the immune-mediated reaction of graft to the leukemia cell, is called graft leukemia (GVL) effect.
Marrow is not unique source of hemopoietic progenitor cell.Peripheral blood and bleeding of the umbilicus also can be used as the source of stem cell.Referring to McCullough, blood ingredient of new generation, blood transfusion (Transfusion) 35:374 (1995).But systemic application nutritional factor (as granulocyte-G CFS) improves the propagation of peripheral hematopoietic stem cells, thereby produces the substitute of marrow, is used to gather in the crops hemopoietic progenitor cell.
Unfortunately, the major obstacle of successful BMT is the recurrence of graft versus host disease (GVHD), infection and primary disease.GVHD and infection cause M ﹠ M (" basis and clinical immunology " (the Basic and ClinicalImmunology) that transplants 10-30% in back preceding 100 days, the 8th edition, Daniel P.Stites, Abba I.Terr and Tristram G.Parslow (volume), Appleton ﹠amp; Lange, Norwalk CT, 1994).If the BMT failure, the unrestricted propagation of tumors remaining cell can cause " recurrence ".Referring to people such as Slavin, " with the immunotherapy of immunocompetent lymphocytes and the minimum remaining disease of active cells factor pair thereof ", cancer research (Cancer Investigation), 10:221 (1992).Past therapeutic treatment is in this case selected very limited.For example, the widespread use of bone marrow transplantation and/or cytotoxic drug is relevant with extremely low survival rate for the second time.
Yet, by drawing a kind of therapeutic strategy to transplanting biological understanding more fully.To there being or not having studies show that of BMT under the T cells exclude, for the leukemia of the treatment that can be used for the minimum remaining disease of CML patient or " comprehensively " recurrence was treated, the T cell was important.Based on this understanding, become a kind of generally acknowledged treatment with donor white corpuscle input (DLI) treatment to Leukemia Patients after the bone marrow transplantation.Referring to people such as Kolb, blood (Blood) 76:2462 (1990); Lim, people such as S H., U.S.'s hematology magazine (Am.J.Hem.) 54:61-67,1997; Giralt, people such as S.A., modern viewpoint (Cur.Op.Onc.) 8:89-95 of oncology, 1996.The leukocytic adoptive immunotherapy that also has been used as after bone marrow transplantation is failed that transfers is induced permanent alleviation.Referring to, J.Mccullough, blood ingredient of new generation, blood transfusion, 35:374 (1995).DLI is effective especially for the treatment of CML, but also can be used for the treatment of AML, ALL and CLL.DLI also has been used for the treatment of myelodysplasia (MDS), non_hodgkin lymphoma, Hokdkin disease and multiple myeloma.As if the cell of input cause the immunne response to the acceptor malignant cell.According to the pcr analysis of bcr-abl being reset (Philadelphia chromosome), about 70% recurrence is that the CML patient of chronic phase reaches persistent cytogenetics release behind DLI, and becomes (Drobyski, the people such as W.R. of remaining disease-negative, blood 82:2310-2318,1993).
Yet this method has danger, because GVHD takes place 80% among the patient, 56% osteomyelodysplasia takes place.This is two major causes of treatment failure, causes reaching 20% reaction patient's death (Champlin, people such as R., hematology journal (Act.Haemat.) 95:157-163,1996).GVHD causes by the donor T lymphocyte that exists among BMT that transfers or the DLI, breeds and is settled in host tissue.In case propagation, donor T cell is promptly attacked host tissue, causes pathological symptom.
The elimination of disease is considered to owing to the immune response of graft to tumour cell behind the DLI, i.e. GVL effect (Barrett, people such as J., the modern viewpoint of oncology, 8:89-95,1996).The mechanism of GVL effect is not got clear as yet fully.It is the T cell realization that origin comes from donor, because the BMT of T cells exclude causes the more high incidence of leukemia relapse.Immunne response is that this effect of generation is necessary, and BMT compares with allogeneic, and higher recurrence rate has proved this point (Duell, T., international medical science annual report (Ann.Int.Med.) 126:184-192,1997) behind the homology BMT in experiment.In Japan, crowd's high homogeneity causes invalid DLI treatment, because donor and host are not fully allochthonous (Takahashi, people such as K., lancet (Lancet) 343:700-702,1994) at random.
Clinical effectiveness shows that the GVL effect can be distinguished with pathogenic GVHD.Patient with the allogeneic BMT of T cells exclude treatment shows higher recurrence rate than the patient with BMT and standard GVHD prophylactic treatment, even when control GVHD sickness rate is counted still (Horowitz, people such as M.M., blood 75:555-562,1990) like this.The case that many reports are also arranged is observed the release of CML and is not had the morbidity (Duell, T., international medical science annual report 126:184-192,1997) of GVHD.In animal model, the differentiation of GVHD and GVL be attainable (referring to, for example, Johnson, people such as B.D., bone marrow transplantation (Bone Marrow Transplant.) 11:329-336,1993; Glass, people such as B., Britain's hematology magazine (Br.J.Hem.) 93:412-420,1996; Johnson, people such as B.D., blood 85:3302-3312,1995).
For fear of Acute GVHD, remove donor T lymphocyte or the mature lymphocyte that in BMT, exists with several technology.Yet current do not have effective marrow to handle to avoid GVHD fully, because in most of the cases the GVL effect is weakened, cause higher recurrence rate (Kantarjian, people such as H.M., blood 87:3069-3081,1996).Some experimental technique of people and animal model comprises, the eliminating of T cell subsets, UVB shines (Greenfeld, people such as J.I., surgery research magazine (J.Sur.Res.) 60:137-141,1996), or the T cells exclude adds a certain amount of T cell, the shortage (Drobyski of the GVHD of a certain amount of T cell of titration subsequently again, W.R. wait the people, blood, 82:2310-2318,1993).In a kind of strategy, with a kind of " suicide gene " transfection donor T cell, this gene provides the herpesvirus thymine deoxyriboside kinase of the susceptibility of medicine gancyclovir (HSV-tk) gene.If observe the GVHD symptom, then give patient's gancyclovir to eliminate the T cell in vivo, up to resolution of symptoms (Bordignon, people such as C., human gene therapy (Hum.Gen.Ther.) 6:813-819,1995; People such as Bonini C., science (Science) 276:1719-1724,1997).Another kind of " suicide gene " method is used the FAS gene of coding apoptotic signal transferrin (Ariad Pharmaceuticals).In the FAS system, induce FAS to produce with a kind of dimerization agent such as FK1012, kill and wound the donorcells of expressing this gene.
" suicide gene " also has many significant disadvantages although perhaps method is attractive from treating the viewpoint of eliminating unwanted T cell after the remaining cancer.At first, use the GVHD symptom signal of pharmacological agent to start with.Therefore, GVHD should be able to begin and must be able to close.Secondly, the medicine that is used for eliminating the T cell must systemic administration, thereby whole health being contacted with medicine reach makes the controlled necessary certain hour of GVHD.Gancyclovir has toxic side effects, and HSV-tk albumen is immunogenic.In addition, because the patient that needs protection avoids the severe form of GVHD, so the immunosuppression prevention is still indispensable.Equally, in some chronic GVHD example, prove that using of gancyclovir is not (people such as Bonini C., science 276:1719-1724,1997) in full force and effect.This perhaps be since this method prevent the explanation misread, promptly having only proliferating cells is the gancyclovir sensitivity.In addition, even the proliferating cells auxiliary effect (Good Samaritan effect) of escaping gancyclovir of enzyme that also can provide by near the normal cell that exists the contiguous HSV-tk cell.
For the FAS system, shortcoming comprises synthetic difficulty and induces the insoluble of dimerization agent that FAS produces.The proteic combination of FKBP can be limited the available medicine among dimerization agent and the host.
In addition, technology relevant with gene therapy and practice are considered to make and are difficult to carry out application with control techniques.The generation of transfectional cell is perplexed by poor efficiency, and this makes when the GVHD sign occurring, and the ability of the homogeneity of processed cell colony and total kill cell becomes problem.Cell must can be bred time several weeks, and this means between harvested cell and transfectional cell can be used for time of infusion has a delay.At last, and also be most important ground, the cell in the input human body may contain the genetic material of modification, and it might have deleterious effect for a long time to the host.
Ionizing rays (γ-radiation or X-radiation) or UV line (UVC λ=200-280nm; UVB λ=280-320nm; UVA λ=320-400nm) has been used to the processing blood goods and has come dna damage in the inducing cell.The method of the GVHD prevention that current generally acknowledged being used to transfused blood relevant is γ-radiotreatment (2500 cGy).γ-radiating the clinical dosage that is used to prevent TA-GVHD causes T cell alive to reduce 10 5-10 6Doubly.Yet γ-radiation and ionizing rays are not special for nucleic acid usually.Because its high-energy, γ-radiation and UVC are also attacked protein and other cellular constituent, cause tangible non-specific damage (Deeg, people such as H.J., hemocyte (Blood Cells) 18:151-162,1992).In order to prevent GVHD, the viability that keeps BM progenitor cell and original hemopoietic stem cell with the propagation of UVB elimination rat lymphocyte is used for implanting.At 4000J/cm 2The UVB treatment dosage time, CTL is active to be reduced but still has (Gowing, people such as H., blood 87:1635-1643,1996).Yet the UVB radiation also causes tangible cell injury, particularly (Gowing, people such as H., blood 87:1635-1643,1996 when using the lamp of wide emmission spectrum; Pamphilon, people such as A.A., blood 77:2072-2078,1991).Reported the surface molecular chemically modified and the film rupture that cause low cell survival and immune response inducing, this perhaps is because UVB induced protein and the lipid ability of the chemically changed of unsaturated link(age) especially.These restrictions are because UVB is not only selective to nucleic acid, but modify this fact of any chemical group that absorbs 280-320nm.
Be used for human leukocyte processing, the demonstration of the UVA radiation in the presence of photosensitizers 8-methoxypsoralen (8-MOP), the stimulation ability and the propagation (Kraemer that in external mixed lymphocyte culture reaction, suppress peripheral blood leucocyte, K.H. wait the people, dermatological studies magazine (J.Inv.Derm.) 77:235-239,1981; Kraemer, people such as K.H., dermatological studies magazine 76:80-87,1981).Yet, described in these reports, UVA adds psoralene and handles inhibition (Gruner, the people such as S. who causes surface antigen expression, cytokine synthetic (IL-1, IL-6, IL-8 and INF) and cytokines mRNA to be transcribed, tissue antigen (Tiss.Ant.) 27:147-154,1986; Neuner, people such as P., photochemistry and photobiology (Photochem.Photobiol.) 59:182-188,1994).Therefore, the photochemical treatment described in the former research (PCT) condition is although suppress propagation and reduce non-specific cell injury, the also immunologic function of deactivation T cell; These treatment condition can not produce the cell that any immunoprotection effectively is provided or induces the GVL effect in order to transfer purpose.At last, spleen and myelocytic UVA are added the reduction (Ullrich, S.E., dermatological studies magazine 96:303-308,1991) that the 8-MOP processing has been successfully used to GVHD in the mouse model.As former all reports, this research is at the leukocytic GVHD of donor aspect, and do not provide immunoprotection or GVL function for white corpuscle.
Obviously, have the needs to novel method, the GVHD that suppresses between allohistocompatibility's obstacle induces, and does not need to contact with the system of medicine.This method can provide certain immunoprotection to the individuality of non-responsiveness, and/or allows the killing and wounding of residual cancer, but should be able to prevent to import the propagation of cell in the host.
In this description and require the present invention of patent protection, by providing preparation not induce GVHD but keep the leukocytic method of leukocyte function, at and overcome these and other problem relevant with prior art.By the following detailed description, this and other advantage that method of the present invention had will be obvious.

" allogeneic " refers to the relation that exists between the members different in the heredity mutually of the same race, and namely these members are not homologies.
" host " can with " acceptor " exchange interaction, refer to the leukocytic mammalian receptors of allogeneic donor. Usually, the host is the people, but also comprises other mammal, such as mouse, dog, cat, monkey, horse etc.
" leucocyte " refers to any leucocyte, comprises the pedigree CFU-GM. " antigen presenting cell " comprises macrophage, and the dendritic cells of a small amount of existence in peripheral blood, and their precursory cells separately. Leucocyte be present in the blood circulation and marrow in, and the myelocyte formation of reticuloendothelial system, lymph and netted position.
" leukocyte population " refers to contain the leukocyte population that surpasses a kind of leucocyte cellular type as used herein, and comprises at least T cell, antigen presenting cell and NK cell.
" donor leucocyte " refers to for host animal is not endogenous and derive from a kind of leucocyte of allogeneic donor. Use for external and non-human, leukocyte population and donor leucocyte can derive from mammal, comprise rodent, rabbit, dog etc.
" purifying " meaning is, leukocyte population is separated from health, and processed so that be substantially free of non-leukocytic cellular type, and does not preferably contain other pollutant, such as the cell relic that exists in the leucocyte source, this source is generally peripheral blood, marrow even splenocyte. Preferably, the purifying leukocyte population contains it and is less than 13% red blood cell (RBC), more preferably is less than 5%, even more preferably is less than 1%. In a kind of the most preferred embodiment, hematocrit levels is lower than 0.5%. The leucocyte purification process has below been described.
" treated leucocyte " refers to be exposed to or contacts a kind of leucocyte that can form with nucleic acid the compound of one or more covalent bonds. Leucocyte can be by PCT or with alkylating agent compound " processing ". " photoinactivation " or " photochemistry suppresses " (PA) or " PCT suppresses " leucocyte PCT leucocyte of referring to even still can not breeding and do not mean that leucocyte is being inactivated aspect protein expression and the immunologic function after stimulation.
Leukocyte population of the present invention contains but is not limited to " not breeding " cell. If it is suppressed to copy middle cell at DNA, thereby even after stimulating with reagent such as mitogen, cell factor, antigen, antibody or other propagation stimulus, still can not divide and produce new cell, then this cell is " not breeding ". Method of the present invention causes in the preparation every kind of leukocytic copying all to suppress optional. For the present invention, as long as the small part leucocyte that can breed is not enough to cause GVHD in the allogeneic host, then in the colony of purifying at least 90%, more preferably at least 95% the leucocyte, leukocyte population breed be suppressed just enough. In a kind of the most preferred embodiment, in the colony 99% or more leucocyte do not breed. For example, by limiting dilution test (LDA) or pass through separately3The H-thymidine mixes method, or as described in the following Examples as the part of MLR test, can measure proliferation activity. In a kind of the most preferred embodiment, the T cell in the colony is suppressed to the lower limit that LDA detects by propagation. Shown the ability that the treated leucocyte of these result of the test indications is bred in vivo.
" graft versus host disease " or " GVHD " result from the clone expansion that is present in the donor T cell that transfers among BMT or the DLI, breed and be settled in host tissue. The generation and the order of severity and the existence relevant (referring to Kernan, the people such as N.A., blood 68:770-773,1986) that can clone the T cell of GVHD have been confirmed. With the patient of donor HLA-coupling in, GVHD results from minor histocompatibility antigen. The morbidity of GVHD is the shortage owing to immunologic function among the immunosuppressant patient, and this is the necessary condition of BMT success. Donor T cell can not bred in this environment under fire, and attacks host tissue, causes pathological symptom. On cellular level, host's antigen presenting cell and donor T cell interact in the scope of major histocompatibility complex (MHC) I and II, and induce it to the activation of the cell that carries host specificity (less important) antigen. This causes the clonal expansion of activated T cell, and it attacks host tissue and the release cells factor. The cell factor of T emiocytosis also activates multiple other effector cell of host, and this other generation by cell factor (cell factor tide) increases the weight of tissue damage. Referring to, Burakoff for example, the people such as S.J., graft versus host disease immunology, Pathological Physiology and treatment. In Brinkhous KMS, S.A. (volume): " hematology " be the 12nd volume (front page) (Hematology), New York, Marcell Dekker, Inc., 1990,725 pages.
When diagnosis had GVHD, the immunosuppressive drug that usually gives patient's high dose suppressed GVHD. Yet these medicines also make the leucocyte of transplanting invalid aspect GVL, and the patient can be recurred and is leukaemia.
Leukocyte population causes that the ability of GVHD can be as measuring as described in following examples 4 in vivo, perhaps by limiting dilution test (LDA) at external test, perhaps as described in following examples 5, measure by MLR. Measure according to LDA, if the cell quantity of the cloned T in the colony is 10 of existence in the leucocyte control population (positive control of GVHD and propagation) that is untreated-3-10 -4, judge that then this leukocyte population can not cause GVHD. In vivo, the shortage of GVHD clinical symptoms (embodiment 4 described symptoms) shows that this colony can not cause GVHD in the allogeneic acceptor of leukocyte population.
If a kind of leukocyte population comprises such leucocyte, it can directly or indirectly participate in effectively killing and wounding or to remove the immune response of target disease cell (or pathogen) or restriction disease cell (or pathogen) propagation from health, then think this colony " be effective for the destruction that promotes disease cell or pathogen ". Be not that the every kind of leucocyte that exists in the leukocyte population can both promote to destroy, but this colony should be effective in this regard generally.
Will be appreciated that disease cell or cause of disease physical efficiency are destroyed by any mechanism. Can mediate the leukocytic method of specific mechanism restriction processing of destroying by treated leucocyte is not purpose of the present invention. The disease cell can be destroyed by cytolysis by T cell or NK cell, and can be killed and wounded by other mechanism, as is induced to experience apoptosis. Disease cell or pathogen also can be relied on the cell-mediated cytotoxicity (ADCC) of antibody, the phagocytosis of macrophage destroys, or removed by reticuloendothelial system by naturally occurring arbitrary immunologic mechanism in the mammal. The host cell that relies on by killing and wounding its survival can destroy the pathogen that resides in the host cell indirectly. Learn textbook such as " Preclinic and clinic immunology " the 8th edition at standard immunoassay, Daniel P. Stites, Abba I.Terr and Tristram G.Parslow (volume), Appelton ﹠ Lange, Norwalk CT, in 1994, immune system has been discussed has been made body break away from the mechanism of malignant cell, infected cell or pathogen. The donor leucocyte that " effectively " processes can be a kind of effector cell, such as cytotoxic T cell (CTL), NK cell or a kind of macrophage, and its direct killing target disease cell or pathogen, or induce disease cell experience apoptosis. In addition, by stimulating other leucocyte, for example come from the marrow of transplanting, the leucocyte of former DLI, or host's self leucocyte, treated donor leucocyte can mediate destruction, thereby kills and wounds or remove. Can stimulate other leucocyte by surface antigen expression, cytokine secretion or any suitable mechanism. Cytolysis can occur in the mechanism through MHC-restriction and/or non-MHC restriction (such as the NK cell).
The usefulness that leukocyte population promotes disease cell or pathogen to destroy can be by multiple test determination, MLR as described in the following Examples or51The Cr release test. For example, according to51The ability that the mediation leukaemia kills and wounds in the Cr release test has proved cytolytic usefulness. For the present invention, if in suitable test (for example51The Cr release test), leukocyte population shows the molten cell ability than high at least about 20% the level of negative control colony, thinks that then this colony is effective to the destruction that promotes the disease cell. Below provide for disease cell and the pathogen type of killing and wounding.
Usually, promote the usefulness of destroying to need leukocyte population to keep certain synthetic level of protein, produce and secretion so that comprise the albumen mass-energy of signal transducers (such as cell factor). Preferably, on plasma membrane, also there is surface antigen to comprise acceptor, the expression of adhesion molecule and costimulatory molecules. Cell survival and film integrality are important for mediation GVL effect. " cell survival " is defined herein as in the circulation is survival rate in blood flow and other tissue.
Although the generation of some cell factor can be suppressed, preferably the cell factor generation remains on at least 70%, more preferably 80% before the above-mentioned compound treatment even more preferably is higher than 90%, most preferably is higher than 95% level. Preferably, leukocyte population is included in the leucocyte that stimulates lower at least secreting leukocytes mesonium-2 (IL-2) and interferon-γ (IFN-γ). Because the clearly effect of these cell factors in t cell activation and GVHD/GVL, they are correlated with. Other relevant cell factor comprises granulocyte-macrophage colony stimutaing factor (GM-CSF) and interleukin 10 (IL-10). For example, can easily measure the secretion of cell factor with the described cytokine assay kit of the following part of present embodiment (for example, the kit of R ﹠ D Systems).
The surface antigen that leucocyte in the purifying leukocyte population is expressed (being also referred to as surface markers) depends on specific cellular type. Preferably, this colony comprises the leucocyte of expressing following surface antigen: CD2, CD28, CTLA4, CD40L (gp39), CD18, CD25, CD69 (lymphocyte activator mark) and CD16/CD56, antigen, known they participation T cells interaction and immunologic function relevant with the NK cell-stimulating. Preferably, leucocyte is also expressed other surface markers, comprises MHC I class and II class, CD8, CD4, CD3/TcR (φt cell receptor), adhesion molecule such as CD54 (ICAM-1), LFA-1 and VLA-4, and other co stimulatory molecule. Available many measure method can detect and measure the expression of surface antigen, for example analyzes to use by standard FACS-SCAN the special antibody staining cell of specific antigen is also detected by the antibody of direct or indirect mark. Other method known in the art comprises immunoprecipitation and the Western blotting of surface antigen.

Below summed up a plurality of preferred aspect of the present invention, and in subsequently detailed description and embodiment, further described and illustrate.
The invention provides a kind of method, be used to handle isolating leukocyte population, can cause the degree of minimum GVHD, can effectively promote disease cell or the enough immunologic functions of pathogenic agent destructive but still keep so that the part of this colony can not be bred to this colony." minimum GVHD " meaning is that the degree of GVHD is not enough to cause mammiferous death, or eliminates the ability that leukocyte population promotes disease cell or pathogenic agent destruction and/or mediation GVL effect.
GVHD clearly with the clone of donor T cell expand relevant, in principle, removal, deactivation or to kill and wound leukocytic any processing all be effective to it.On the other hand, GVL is relevant with the leukocytic immunne response of donor, and may be the result of the synthetic or above combination of cytolysis, antigen presentation, the specific cell factor.To need leukocytic some function of donor be complete for observing the GVL effect.In the trial of avoiding GVHD, also make donor BM or white corpuscle can not be effectively provide necessary immunologic function for non-responsiveness person or BMT host to the deactivation of donor leukocyte function.
Immunoprotection still is provided and/or induces the GVL effect in order to make processing in the allogeneic host, eliminate GVHD, must optionally remove leukocytic multiplication capacity, and keep the leukocyte function of certain level.The invention provides leukocyte population with these features.
Many advantages of the colony of the use of addressing before isolating leukocyte population of the present invention provides and has been better than.A tangible advantage is that the morbidity of eliminating GVHD will allow the safety input of donor white corpuscle in the patient.Therefore, lack immunity system or have chimeric immune host and can accept heavy dose of treated donor white corpuscle and/or DLI repeatedly, thereby improved the usefulness of disease treatment.In the past, the threat of GVHD had limited the leukocytic amount of input.
The non-proliferative leukocyte population can provide the abundant immune defense of antagonism cancer and infection effectively for the host.These white corpuscles can be used for treating the hematologic malignancies of recurrence, as the leukemia and the myelomatosis of chronic marrow, acute myeloid, acute lymphocytic, multiple myeloma and other form, as a part for the treatment of behind the BMT or as a kind of selection method that is equipped with of BMT.The GVL effect that DLI causes not only can be used for removing minimum remaining disease, and can be used for the treatment of higher malignant cell load, especially because the shortage of white corpuscle expansion allows the safety input of greater amount cell.Treated leukocyte population of the present invention also can be used for the treatment of some solid tumor (for example mammary cancer and renal cell carcinoma) to the immune modulating treatment sensitivity, and can be used for preventing mating and mispairing allosome BMT process in transplant rejection.Other various clinical indication that this treated white corpuscle is suitable in treatment below has been described in detail in detail.
The leukocytic method of processing of the present invention comprises the following steps.Can from marrow, bleeding of the umbilicus or whole blood, obtain white corpuscle.The white corpuscle source of most convenient is a peripheral blood.Described in the scientific literature from other source and separated leukocytic method.For example, come purifying and enrichment white corpuscle by red corpuscle removal or white corpuscle electrophoretic process whole blood.The purifying leukocyte population about 99% that obtains does not contain red corpuscle, and comparing red corpuscle with white corpuscle has different sizes and density, is easy to remove by these methods.
Then with leukocyte population and compound, and do not damage effectively suppressing white corpuscle propagation under the condition of cell survival and integrity and handle.Remove unreacted compound, perhaps prolong this compound in time and can be changed into non-activity, and unnecessary removal.In a kind of preferred embodiment, " compound " is meant the compound that can form covalent linkage with a kind of nucleic acid.Covalent linkage be formed on per 10 8Can form about 1-10 in the individual white corpuscle genomic dna base pair 4Individual adducts, preferably 5-10 3Individual adducts, most preferably 10 3Individual adducts.Importantly, the feasible non-specific damage to protein and other cellular constituent of treatment condition reduces to minimum and avoids membrane damage.Most of treated leukocytic film integralities are necessary for the GVL effect takes place.These treatment condition can not cause GVHD after also making treated white corpuscle effectively in introducing the allogeneic host, perhaps make it anergy in the MLR in vitro test.In addition, treated white corpuscle should keep for finish immunologic function, especially for promote disease cell or pathogenic agent in vivo the destruction effective protein proteins matter of (or external) express.
Following discloses can be with nucleic acid, preferably double-stranded DNA forms the character of the suitable compound of covalent linkage.These compounds can contain a kind of part that can form covalent linkage with nucleic acid, but this part is photoactivation or chemically reactive.This compound is by forming covalent linkage with genomic dna and then disturbing the function of archaeal dna polymerase and white corpuscle can not be bred, the propagation that suppresses cell can be regulated the quantity of the covalency adducts that compound and white corpuscle nucleic acid forms, make this compound can suppress propagation, but keep promoting the effective immunologic function of destruction of disease cell or pathogenic agent.Use the alkylating agent compound,, can regulate this effect by regulating compound concentration and white corpuscle contacts with compound before removing unconjugated compound time span.Required concentration depends on the character of specific compound, as solubleness in the aqueous solution and DNA binding constant.Generally with per 10 8Can effectively produce about 1-10 in the individual white corpuscle genomic dna base pair 4The adducts of individual covalent attachment compound, about 5-10 preferably 3Individual adducts, more preferably about 10 2-10 3The concentration of individual adducts is used this compound.Ideally, handle the condition of leukocyte population per 10 8To produce about 10 in the individual genomic dna base pair 3Individual adducts.The minimum compound concentration that can effectively obtain leukocyte compositions of the present invention is preferred concentration.
But use light-activated compounds, can regulate the PCT effect by the time span of regulating compound concentration, wavelength of light and being exposed to light.Use psoralene and other light-activated compounds to carry out the condition of PCT but below described in detail.
The purpose of treatment condition is per 10 8Produce about 1-10 in the individual white corpuscle genomic dna base pair 4The adducts of individual covalent attachment compound, about 5-10 preferably 4Individual adducts, more preferably about 10 2-10 3Individual adducts.Ideally, these treatment condition are per 10 8To produce about 10 in the individual genomic dna base pair 3Individual adducts.For example, by using radiolabeled DNA binding compounds as described in the following Examples, energy measurement is by the quantity of handling the compound-dna adduct that produces.
The compound of the another kind of type that can use in white corpuscle is handled is a kind of small molecules as the dna replication dna inhibitor.As mentioned above, this small molecules replication inhibitors can randomly contain a kind of linker (brittle or opposite) and a kind of effector part.Any step of dna replication dna can both be as the target that suppresses, and the formation, ORC that comprises origin recognition complex (ORC) is to initial, the extension that replenishes, duplicates of starting point etc.In addition, helping the inhibitor of the enzyme of reproduction process, as helicase and topoisomerase, also is useful.The example of topoisomerase enzyme inhibitor comprises, for example camptothecine and daunomycin.
In order to make white corpuscle sample and compound, compound of the present invention can be introduced in the leukocyte suspension (white corpuscle sample) with several forms.Can be used as the aqueous solution in water, the salt solution, synthetic medium (as " Sterilyte TM3.0 ") or the leukocytic solution introducing compound that suspends.Below provide and be suitable for the leukocytic solution of resuspension (blood transfusion level and non-blood transfusion level)." synthetic medium " is defined as water-based dextran or blood products storage medium at this.Can provide compound with the drying agent that contains or do not contain adjuvant in addition.Stir cell suspension then and mix this compound.
The white corpuscle of stand-by compound treatment is resuspended in the physiological balanced solution, as blood plasma, synthetic medium or its composition.Can provide white corpuscle with the volume of 200mL-1L.The white corpuscle that is used for handling preferably is contained in a kind of reaction vessel such as blood bag.The blood bag is known in the art.
Can monitor with the influence of compound treatment by external and in vivo test, thereby determine to make propagation and GVHD activity to reduce to minimum and make cytotoxicity function and/or GVL effect reach maximum optimal treatment condition leukocyte population viability and function.Top condition will be different with the character of compound used therefor, and be confirmed by disease or pathogenic agent.But for light-activated compounds, most preferred PCT condition comprises minimum compound concentration and minimum light dosage, and it is enough to provide propagation to be suppressed but can effectively promotes disease cell or pathogenic agent destructive leukocyte population.The leukocyte population that following sign is treated.
The cell survival of treated leukocyte population will be estimated.With as described in the lower section, for example, detect the sequence special as present embodiment, can measure the viability of cell in vivo the donor white corpuscle by pcr analysis.Preferably, this leukocyte population has the cell survival at least 3 weeks.Handle the leukocytic quick removing in back and can influence the ability that it induces the leukemia reaction.Processed leukocytic film integrality also is necessary for the GVL effect takes place.Can measure film integrality by trypan blue or the iodate third ingot dye excretion.If use,, optimize the PCT method in that the leukocyte count with intact cell film is reached aspect the maximum light dosage and/or compound concentration.
As described in following present embodiment, for example, can measure proliferation activity by limiting dilution test (LDA) or mixed lymphocyte reacion (MLR) test.The processed white corpuscle of the active indication of white corpuscle in mixed lymphocyte reacion (MLR) test mediates the ability of GVHD in vivo.In addition, GVHD symptom and/or the GVHD inductive M ﹠ M of having imported in the treated leukocytic MHC coupling animal by monitoring can be determined GVHD.
, the expression of surface antigen mark synthetic by the monitoring cytokine and the ability of dissolving target cell can be determined the white corpuscle activity.Utilize the expression of suitable antigen-specific antibodies and standard FACS-SCAN assay determination surface antigen mark.As the existence of function mensuration antigenicity mark CD2, CD28, CTLA4, CD40 part (gp39), CD18, CD25, CD69 (lymphocyte activator mark) and the CD16/CD56 of covalent attachment compound concentration and when using (if) PCT light dosage, known they participations interaction and immunologic function relevant with the NK cell-stimulating with the T cell.If PCT to the protein action temperature and, the stability prediction of PCT condition lower surface molecule is unaffected.Select for example PCT of treatment condition, make them can not influence the expression of surface molecular on the contrary or production of cytokines is reduced under the level of hope (above disclosed preferred levels).
For example, exist 51By the dissolving of people or L-1210, can measure the active dissolved cell activity of indication GVL in the Cr release test.As people such as Choudhury, blood 89:1133-1142,1997 described can be in external test leukemia effect, perhaps as people such as Johnson, blood 85:3302-3312,1995 describedly measure in vivo.The activity energy use-case of solid tumor such as the mouse model of solid tumor are detected.Mediation infected cell or pathogenic agent dissolved ability can be measured with infected animals in animal model.GVHD and GVL ability also can be measured as described in following examples 4 and 5 in vivo.

In a kind of preferred embodiment, utilize wavelength for the ultraviolet ray of 320-400nm to carrying out PCT with S-59 blended white corpuscle.The wavelength that the photoactivation method is limited to greater than 320nm makes direct nucleic acid damaging reduce to minimum, because the absorption of nucleic acid is very little when being higher than 313nm.Cell preferably will accept about 10 -3-100J/cm 2, 1-3J/cm more preferably 2Light dosage.In a kind of the most preferred embodiment, light dosage is 3J/cm 2Irradiation is generally 1-50mW/cm 2Light intensity.The time that the white corpuscle sample is exposed to the UV line is about 1 second to 60 minutes, preferably about 3 minutes, and more preferably about 1 minute.
Behind the PCT, as above reach the described mensuration white corpuscle of embodiment sample propagation and participate in the active usefulness of white corpuscle.Mainly be to measure following parameters: cell survival, multiplication capacity, cytokine secretion and surface antigen are expressed.Treatment is used
Treated leukocyte population of the present invention be do not breed but keep immunologic competence, as described below have multiple prevention and a therepic use.Usually, the individuality of accepting to contain the DLI of treated leukocyte population includes but not limited to the transplant patient, carries out the patient of solid organ transplantation as transplant patient behind the BM or expection.Treated white corpuscle can not cause that this fact of GVHD makes and can use more substantial white corpuscle (promptly bigger cell dosage) in DLI, thereby make the usefulness of treatment reach maximum.
Treated white corpuscle can be used for donor leukocyte infusion (DLI), especially provides immunocompetence to allosome BMT patient or non-responsiveness patient (as suffer from CLL gerontal patient).Use treated leukocytic DLI to can be used for alleviating and comprise following various disease conditions:
Leukemia comprises chronic lymphocytic leukemia (CML), lymphocytic leukemia (CLL), chronic myelomonocytic leukemia (CmML), acute myelogenous leukemia (AML) and acute lymphoblastic leukemia (ALL); Multiple myeloma (MM); Non_hodgkin lymphoma and He Jiejin lymphomas; Large celllymphoma (LCL); With Epstein-Barr virus inductive B lymphocytic hyperplasia disease (EBV-BLPD or EBV-inductive lymphoma);
Solid tumor comprises mammary cancer, lung cancer, ovarian cancer, carcinoma of testis, prostate cancer and colorectal carcinoma, melanoma, renal cell carcinoma, neuroblastoma, neck tumour;
Aplastic anemia; Myelodysplasia;
Immune deficiency, for example common panimmunity defective, SCID, Wei-Ao two syndromes;
Agranulocytosis;
Mix chimerism; With
Inherited disease.
DLI can be used to prevent or the various ways of therapeutic purpose:
(a) to the adoptive immunotherapy of all allotransplantations;
(b) for immunosuppression or immune deficiency patient's immunologic reconstitution;
(c) to the old leukaemic's that is unsuitable for transplanting treatment
(d) a small amount of or small-sized transplanting of BMT.
The a small amount of scheme of BMT is the method for two steps, comprising: i) use minimal condition scheme and stem cell donator inducing transplantation tolerance; Ii) repeat treatment with DLI.This scheme has been avoided the toxicity of chemotherapy scheme.The a small amount of scheme of BMT is applicable to following indication: can not normally be suitable for patient, the especially gerontal patient (>65 years old) that transplant; CLL patient, the wherein serious non-responsiveness of great majority.The a small amount of scheme of BMT has reduced toxicity, GVHD and infection.The a small amount of scheme of a kind of typical B MT has been described in following examples 13.
(e) CD34 select/allotransplantation of T cells exclude adds DLI simultaneously.
The DLI that the cell of selecting with CD34+ (for the selection of stem cell enriched and progenitor cell) provides simultaneously can be used for providing the adoptive immunotherapy to infecting, the infection that causes as CMV, Epstein-Barr virus (EBV), adenovirus (Ad), kaposi sarcoma-associate herpesvirus, and fungi infestation, and can be used for treating leukemia, for example CML.
(f) treatment of mixing chimerism.
(g) remedy chemotherapy or chemoresistance leukemia.
In one embodiment of the present invention, in transplanting, monoploid identical (doubly single) imposes PA-DLI.Usually, single T cells exclude that needs almost completely of transplanting causes immunosuppression serious, that continue.PA-DLI can be used for keeping host's immunocompetence; In addition, can be treatment for cancer GVL is provided effect.
In preferred embodiments, no GVHD ability of the present invention but keep the white corpuscle of some immunologic function, removal, the especially CML and acute leukemia, lymphoma and the multiple myeloma that in DLI, are used for minimum remaining disease behind the alleviation of relapsed cancer or the allogeneic BMT.The usefulness that the special a large amount of donor CTL of the bcr-abl protein of CML is helped to recur DLI among the CML.Can detect malignant cell if be conventionally used for the method for monitoring cancer cells existence by the doctor, determine that then the cancer patients suffers from " recurrence ".
In another embodiment, during inducing chemotherapy (chemotherapeutical the junior one wheel), use in leukaemic's the treatment and contain the leukocytic DLI of non-proliferative, avoid severe bone marrow depression scheme and eliminate minimum remaining disease.In this arrangement, use DLI, can reduce the poisonous dosage of used chemotherapeutics between inductive phase.
In one embodiment of the present invention, PA-DLI also can be used for the transplanting (for example kidney, heart, skin) of solid organ, as a kind of method that improves the chance of allogeneic life-span and donor organ acceptance.Because the existence of passenger leukocyte in the donor organ, big multigenerator official repels in heteroplastic transplantation.Owing to not breeding and can not mediating GVHD, tolerance scheme before DLI (using the white corpuscle of organ donor) can be used as and transplants is used for and will otherwise induces the inhibition of organ rejection's immunne response.For the host's of solid organ transplantation tolerance comprise the following steps: before the organ transplantation process or during, contain or do not contain the PA-DLI input of stem cell donator with the suitable severe bone marrow depression scheme of level, donorcells can be survived in circulation.DLI can be convenient to the implantation of stem cell donator in this scheme, allows the mixing chimerism among the host.
In all types of transplanting and implantation situation, can be before transplanting, simultaneously or afterwards the host is used treated white corpuscle.Can carry out repeatedly the infusion of treated cell colony in any time in these times.
White corpuscle that do not breed, immunologic function is for avoid the patient's of traditional allosome BMT DLI particularly important owing to advanced age or comorbid are sick.The gerontal patient (>65 years old) who suffers from cancer is not the main candidate of allosome BMT, partly is because transplanting can not be rebuild the aged immunity system well, and because the severity of this method.Current, be chemotherapy to the effective unique selection of cancer among the control gerontal patient, its side effect is intolerable for these patients.Treated white corpuscle of the present invention provides the selection method that is equipped with that a kind of ten minutes needs, and is used for the treatment of aged patient's cancer and immune defense to opportunistic infection is provided.DLI does not cause that for destruction of cancer cells the GVHD that follows is useful.
In some treatment situation, before with above-mentioned compound treatment donor leukocyte population, expansion donor white corpuscle subgroup especially T cells with antigenic specificity and precursory cell is desirable.Can use disease cell (for example, tumor associated antigen) or the special antigenic stimulation leukocyte population of pathogenic agent, expand/enrichment is to the cytotoxicity of this antigen-specific and the quantity of helper cell.By before being separated white corpuscle the donor that stimulates with suitable antigen inoculation donor, can stimulate in vivo; In addition, before with the compound treatment leukocyte population, can carry out separating leukocytic stimulation external.
For example, the donor with the IgG of multiple myeloma patients inoculation contains the special CTL of predecessor of high-caliber myelomatosis.Therefore, for the application in the treatment multiple myeloma (MM), the preparation white corpuscle is preferred from the donor of these inoculations.Hsu, people such as FJ, national medical science (Nat.Med.) 2:52-58, described in 1996 for the non_hodgkin lymphoma immune patients and with tumor-associated peptides to the dendritic cell pulse.At Stingl, people such as G., immunity today (Immunol.Today) 16:330-333 has summarized in 1995 with the technology of peptide/antigen to the dendritic cell pulse.Pardoll, people such as D., immunity (Immunity) 3:165-169 has described cDNA immunity (with suitable cDNA transfection dendritic cell) in 1995.At the adoptive immunotherapy that is used for the CML treatment, before separating the donor white corpuscle, can be used for by method treatment of the present invention and infusion subsequently with bcr-abl peptide vaccination donor.For example, ten Bosch, people such as G., blood 88:3522-3527,1996 have described the effective and immunogenic peptide that is used to inoculate.In another kind of embodiment, before the method according to this invention treatment, with prostate specific antigen (PSA) in vivo or external pre-stimulation be used for the donor white corpuscle of prostate cancer therapy.Such inoculation can be used to increase the T of predecessor cell colony and/or the T cell colony special to other tumour specific antigen, virus antigen and other pathogen antigen.
Can be used for patient for non-responsiveness with the white corpuscle of the donor of suitable antigen inoculation provides prevention or treatment to the immune defense of opportunistic infection, and these opportunistic infections such as cytomegalovirus (CMV), Epstein-Barr virus (EBV), kaposi sarcoma-associate herpesvirus or adenovirus (Ad) infect.In a kind of example, can separate its white corpuscle to CMV antigen inoculation donor, and the method according to this invention processing, in DLI, to be used for treating the patient who suffers from cmv infection owing to immunosuppression.The patient of non-responsiveness comprises the patient who is in the immunosuppressive drug treatment, as organ transplantation patient (BM and other organ), HIV or human body, the cancer patients of EBV infection and the individuality with immunodeficient disease.
Also can enlarge the precursory cell set stimulated in vitro donor white corpuscle (being also referred to as stripped expansion).For example, in the multiple myeloma situation, before treatment blocking-up GVHD activity, by with the special MM antigen of the patient who presents by dendritic cell in external cultivation, can stimulate the donor white corpuscle.
Also can utilize stripped or stimulated in vitro expansion leukemia T cell colony to be used for the treatment of CML.In CML, (t (9 in the classical transposition of the breakpoint cluster region (bcr) of the c-abl oncogene on the karyomit(e) 9 on chromosome 22; 22) (q34; Q11)) expression of generation bcr-abl fusion gene and bcr-abl210kD fusion oncoprotein matter.The bcr-abl fused protein is that CML is special, the proteinic two kinds of antigens that main variant is a well-characterized of bcr-abl.Can carry out stimulated in vitro and expand the special T cell of bcr-abl protein, for example, as Choudhury, people such as A., blood 89:1133-1142,1997; Ten Bosch, people such as G., blood 88:3522-3527,1996 and people such as Mannering, blood 90:290-297,1997 is described.The Toplink of representing breakpoint district or contact (new contact aminoacid sequence) is as immunogen, be used for to the human T-cell who derives from healthy donors external immunity (referring to, ten Bosch, people such as G., 1996, as mentioned; People such as Mannering, 1997, as mentioned).The CD4 that produces +The T cell recognition derives from allogeneic CML patient's bcr-abl express cell.In another approach, can be from CML peripheral blood of patients cell external generation dendritic cell (DC), and as antigen presenting cell be used for leukemia T cell stripped expansion (people such as Choudhury, 1997, as mentioned).In general, antigen of donor is the antigen pulse that delivery cell (APC) can be used performance disease cell characteristic, perhaps can cultivate with disease cell (for example, the tumour cell of deactivation) is collaborative; Can before input donor white corpuscle in acceptor, make these APC contact donor white corpuscles then.In addition, the direct T cell colony that can be used for expanding in the donor lymphocyte that contacts of donor white corpuscle and disease cell (or disease cell antigen).
" antigen " that is used for expanding the T cell can be polypeptide, lipid or carbohydrate part (or any combination, as glycoprotein), and can separation or reorganization produce from disease cell or pathogenic agent.The antigen that contains polypeptide does not need to form whole length protein, as long as it comprises at least a epi-position.This antigen can be contained in the vaccine composition as full length protein or its fragment or the fused protein that produces as reorganization, can with or do not combine or otherwise present with a kind of adjuvant.Vaccine can adopt various ways: the disease cell of antigen expressed, or its cell membrane preparation; Perhaps pathogenic agent is preferably the deactivation form.The method for preparing vaccine has instruction in the literature, referring to, for example, Harlow, as mentioned.Immune and external (exsomatizing) stimulates and the method for precursory cell colony expansion is known in the art, referring to, for example, Choudhury, people such as A., blood 89:1133-1142,1997; Ten Bosch, people such as G., blood 88:3522-3527,1996; People such as Mannering, blood 90:290-297,1997.
For using in the body, white corpuscle is generally used in blood plasma, synthetic medium or other physiological buffer solution, and dosage is the every kg of each infusion about 10 5-10 11Individual white corpuscle, volume are approximately 50-500ml or more.These parameters, and are decided by treatment patient's doctor with disease and different with treatment.Standard DLI practice is with every kg body weight 10 7-10 8The dosage of individual cell is used white corpuscle.Can combine with chemotherapy and implement DLI.
For using in the body, white corpuscle of the present invention generally is that intravenously is used.
GVHD is normally obvious in 90 days behind BMT.In order to alleviate the disease among the cancer return patient, preferably after relapse diagnosis, carry out DLI in 1 week-March.For the adoptive immunotherapy behind the allosome BMT, can be from after several years, carrying out DLI before the BMT as keeping treatment.For accepting the cancer patients that DLI replaces BMT, preferably promptly impose DLI in the near future at cancer diagnosis.When not carrying out BMT, can before chemistry and radiation scheme or other treatment plan, during or carry out DLI afterwards.In all indexs, the appropriate time arrangement of DLI will be by determining doctor skilled aspect the disease treatment.

Although MLR will provide the part of the information that LDA provides, it can provide the information about the ability of processed other cell of leukocyte stimulation.Processed leukocytic stimulation can be as a kind of model of leukemia immune response inducing among the MLR, and it transfers among the patient at BMT and is activated by DLI.In this situation, host that antileukemie immunne response (GVL effect) can be existed among the BMT or donorcells starting.B. be subject to processing leukocytic phenotypic characteristic i) the surface antigen marker expression
Utilize the influence of suitable fluorescent-labeled antibody (Pharmingen) and standard FACS-SCAN assay determination PCT or alkylating agent processing to surperficial antigenicity marker expression.As Coligan, people such as J.E., " immunology general scheme: general scheme ", New York, John Wiley ﹠amp; Sons, Inc., described in 1991, utilize suitable fluorescent-labeled antibody (Pharmingen) and standard FACS-SCAN to analyze, as the existence of function mensuration antigenicity mark CD2, CD28, CTLA4, CD40 part (gp39), CD18, CD25, CD69 and the CD16/CD56 of treatment dosage, known these marks participate in and T cell and NK cell-stimulating and the relevant interactions of immunologic function.If it is, then unaffected at the stability prediction of treatment condition lower surface molecule to proteinic PCT and relevant treatment character gentleness; Yet inducing of its expression estimates it is dose-dependent.
About processed human lymphocyte express in propagation, surface markers, cytokine is synthetic and cytotoxicity aspect sign, see embodiment 14.Ii) the leukemia cell is cracking
In order to measure the direct GVL effect that is subject to processing cell induction, research is to the molten cell ability of a series of people and L-1210 (can obtain from ATCC).According to Jiang, people such as Y.Z., bone marrow transplantation 8:233-238,1991 condition is carried out this experiment.As Coligan, people such as J.E., " immunology general scheme: general scheme ", New York, John Wiley ﹠amp; Sons, Inc., 1991 is described, uses under standard conditions 51Cr mark leukemia cell.In supernatant liquor 51All cracking that reach are measured in the radioactive release of Cr, and with as a setting and total cracked contrast compare.The monitoring treatment dosage is to the influence of the molten cell ability that is subject to processing the T cell.Treated white corpuscle by adding cumulative quantity is also observed and whether cracking takes place is carried out this experiment.Can repeat this experiment with the T cell subsets.Although the direct cracking of leukemia system provides a kind of direct mechanism of GVL effect, its shortage may mean that DLI induces a kind of indirect mechanism of GVL effect.Therefore, in addition, can measure cytotoxicity as the generation of IFN-γ, IL-2 or GM-CSF by measuring the cytokine generation.Iii) cells in vivo viability
For the viability of cell treated in the estimated body, after the processing of various dose, the white corpuscle of male mice is imported in female homology or the heteroreceptor.The PCR method that blood sample carried out that the time point that utilization is wished after splenocyte is transferred is taked (Goodarzi, people such as M.O., blood transfusion 35:145-149,1995), the existence of treated cell in the monitoring circulation.This method detects the existence that only is present in the Y-chromosome specific gene sequence in male (donor) cell, has the susceptibility of 1-5 cell of per 50 μ L host blood.This experiment will be measured the influence to the removing of input cell in the Live Animals, and the relation between treatment dosage and the cells in vivo circulation.As people such as Johnson, Scandinavia Journal of Immunology (Scand.J.Immunol.) 45:511-514,1997 is described, by before infusion to leukocytic PKH-26 mark also can detection bodies in treated leukocytic viability.C. the cytokine synthetic quantitatively reaches qualitative sign
Utilization can the commercial Elisa test kit (R﹠amp that obtains; D Systems), after effector cell and the collaborative cultivation of irritation cell, culture supernatant is quantitatively reached qualitative cytokine assay.Test according to the specification sheets that Elisa manufacturer provides.The typical curve that will produce the cytokine standard that the absorbance measurement of each sample and each are measured test kit and provided is compared estimated result.As the function of compound concentration and-under the situation of PCT-light dosage and handle with measure between the function in the timed interval white corpuscle of processing is carried out cytokine assay.Owing to IL-1, IL-2, IL-4, IL-10, the IFN-gamma cells factor are measured in the clearly effect in t cell activation and GVHD/GVL.
Pending white corpuscle cytokine synthetic is determined that it is important producing in the ability that works as the immune response inducing thing at the mensuration cell by cytokine; It also can be used as the mensuration to biochemical function and protein synthesis.
About processed human lymphocyte express in propagation, surface markers, cytokine is synthetic and cytotoxicity aspect sign, see embodiment 14.D. mouse model suppresses and the application of GVL effect inductive for proof GVHD in the body
For research graft versus host disease and graft leukemia effect, mouse is very perfect model.In order to estimate of the influence of treated white corpuscle respectively, use at Johnson people such as B.D., bone marrow transplantation 11:329-336,1993 and Johnson, people such as B.D., blood 85:3302-3312, the transplanting mouse model described in 1995 to GVHD and GVL.In this model, inferior (9Gy) female AKR/J mouse (H-2 that shines deadlyly k), give MHC-then and mate female B10.BR donor (H-2 k) 10 7Individual BM cell adds 3 * 10 7Individual splenocyte.This processes and displays causes the Acute GVHD clinical symptom and is dead in 50 days.The elimination of the splenocyte of input causes the survival fully of mixochimaera, and BMT does not cause 50% mortality ratio.In the present embodiment, before transferring, mice spleen cell is handled, detected the inhibition of handling GVHD to measure, and the lowest dose level that suppresses the GVHD morbidity also is provided according to mortality ratio.Splenocyte is the leukocytic generally acknowledged substitute of mouse blood, because the volumetric blood of mouse is for these experiments and Yan Taixiao.
For the GVL reactivity of evaluation process cell, BMT imported for example PA allosome splenocyte to acceptor after 21 days, attacked with AKR leukemia cell after 7 days then.According to known to, BMT recovers (28 days) 5 * 10, back 4AKR leukemia cell's mortality ratio (Johnson, people such as B.D. transplant 54:104-112,1992) of 95% after the input leukemogenesis of mouse and leukemia are attacked 25 days.On the contrary, the input of BMT allosome splenocyte after 21 days shows, can induce the GVL effect after with the attack of AKR cell after 7 days.This mechanism causes after 70 days 70% survival rate.If proof has the prevention of GVHD, the processing of splenocyte makes and can detect inducing of GVL when no GVHD before then transferring.Its mensuration is that this receptor is attacked with the AKR cell according to the survival rate of the BMT acceptor of the treated splenocyte of input.
Function as treatment dosage detects the influence of the pending leukocytic DLI of use to leukemia attack survival rate, and compares with the control group of the splenocyte infusion that is untreated.Utilize as Johnson people such as B.D., bone marrow transplantation 11:329-336,1993 described PCR assay methods, the chimerism and the leukemia load of detection survival mice.
In this experimental model, before dead, can diagnose the leukemic cause of the death, because leukemia can cause AKR leukemia cell's expansion to the white blood cell count(WBC) or the pcr analysis of blood.The primer special to AKR leukemia cell's specific marker can be used for pcr analysis.According to the death of hanging down white blood cell count(WBC) and splenatrophy and causing by distinctive clinical symptom (change of fur and posture, viscosity fecal etc.) diagnosis GVHD.By the injection still less or more substantial AKR leukemia cell detect the usefulness of PA-DLI to remaining disease of minimum or higher tumour load.
For example pass through the PCT method to leukocytic processing according to the present invention, if under the condition that does not cause GVHD, after imposing the leukemia attack, can induce and improve significantly, think that then this is effective to inducing the GVL effect with the mouse survival rate statistics of handling cell DLI processing.The genotype of surviving animals should also be fully chimeric, because this more high incidence with anosis long-term surviving is relevant in the mankind.In 100 days, the raising of survival rate is easy to proof behind initial BMT.
To handle splenocyte for donor under the leukocytic condition above-mentioned.
About the situation of the treated white corpuscle GVL effect that causes when the no GVHD in the mouse model system, see embodiment 15.

Stand PCT and in the several characteristic of the human peripheral lymphocyte (PBL) of vitro culture in order to characterize the processed cell colony of particular type, to have checked.These comprise viability, T cell proliferation, cytokine is synthetic and secretion, surface antigen expression, vitro cytotoxicity and Fas ligand expression.Viability
Be determined at 3J/cm with trypanblue exclusion method 2Accept the viability of the PBL of 10nM S-59 under the UVA.Survival rate is to be to be 25% after 50%, 4 day after 75%, 3 day after 2 days.In relevant experiment, observe the survival rate of processed lymphocytic dependent dose.Propagation
According to 3H-thymidine mixing in the T cell DNA that allosome stimulates measured lymphocytic propagation.Separating periphery blood monocytic cell (PBMC) from three donors merges, and gamma-irradiation (2500cGy) preventing autostimulation, and is used as irritation cell in MLR.Isolating PBMC action effect cell from the 4th donor.The effector cell is at 3J/cm 2UVA is down with 0.05,0.5 or 5nM 4 '-(4-amino-2-oxa-) butyl-4,5 ', 8-trimethylpsoralen (" S-59 ") is handled, and with the collaborative cultivation of irritation cell.Contrast, untreated effector cell also cultivate with irritation cell is collaborative.Cultivate after 6 days, in nutrient solution, add 3The H-thymidine, harvested cell after a day is by scintillation counting analysis of cells sample determination 3The absorption of H-thymidine.Fig. 8 shows, according among the MLR 3The H-thymidine is taken in the processed leukocytic propagation of being measured, and is eliminated in dose-dependent mode between 0.1nM-10nMS-59, and propagation is suppressed fully during 10nM S-59.
Also available a kind of selection method that is equipped with is analyzed processed leukocytic multiplication capacity, and the anti-CD 3 antibodies with surface bonding in this method activates processed cell.In this test, PBMC or not processed or at 3J/cm 2UVA dosage is handled with 0.0001,0.001 or 0.01 μ M S-59 down or is shone when no S-59.Then in adhering to the culture plate of anti-CD 3 antibodies at 5%CO 2, 37 ℃ of following incubation cells, come the polyclone of inducing T cell to activate, and after cultivating 1,2 and 3 day, measure 3Mixing of H-thymidine.The inhibition fully that result (Fig. 9) breeds when being presented at the reduction of multiplication capacity dependent dose under all treatment condition and 10nM S-59.Cytokine produces
As preceding for described in the part of proliferation assay, cultivator lymphocyte in MLR.At 3.0J/cm 2UVA is down with the S-59 of different concns (0.05,0.5 or 5nM) Treatment Effects cell.Cultivate and take MLR cell culture medium sample after 2,4,6 and 7 days.Measure the IL-2 and the IFN-γ level of these samples with sandwich enzyme-linked immunosorbent adsorption test, and use the spectrophotometry quantitative result.Standardized solution is used for setting up the typical curve that concentration (pg/ml) is associated with absorbancy, comes cytokine concentration in the confirmed test sample by it.
Figure 10 A shows the analysis that IL-2 is produced.Untreated lymphocyte and reach the highest with the lymphocytic IL-2 secretion that low concentration S-59 (that is, 0.005 and 0.5nM) handles when cultivating 2 days is then because IL-2 is bred lymphocyte consumption in the colony descend.On the contrary, in the lymphocyte of handling with 5nM S-59, IL-2 is by the lymphocyte consumption of non-propagation, and still is present in the substratum with quite high level in the time of the 4th, 6 and 7 day.
The IFN-γ of stimulation PBMC produces the influence that is not subjected to the S-59+UVA processing or is improved slightly.See Figure 10 B.The synthesis result of IL-2 and IFN-γ shows that under the repressed condition of propagation, processed cell still can synthesize justacrine and t cell activation related cytokine.Surface antigen is expressed
Analyzed the analysis of processed lymphocyte upper surface marker expression.Obtain lymphocyte through the Ficoll gradient centrifugation, and activate by anti-CD 3 antibodies stimulated in vitro with surface bonding.Use the fluorescence antibody of CD69, CD25 (IL-2 acceptor) or CD40L, express by the lymphocytic surface antigen that fluorescence-activated cell sorting (FACS) assay determination is activated, handles.Express as the function mensuration that activates the back time, and compare with the expression of untreated cell.
CD69 is a kind of early stage mark of lymphocyte activator.Figure 11 A shows, with 1nM or 10nM S-59+3J/cm 2The cell that UVA handles is similar to or a little more than the surface C D69 level of untreated cell up to having in 48 hours time after processing.Therefore, although processed cell can not be bred, still tool is functional with activating relevant signal pipeline.
CD25 is the IL-2 acceptor, and slightly evening, (activating the back) detected its expression in CD69.Figure 11 B shows, compares with untreated cell, with 1nM or 10nM S-59+3J/cm 2In the cell that UVA handles, surface C D25 is unaffected basically.
The CD40 molecule of expressing on CD40 part (CD40L) the identification B cell surface on the T cell is as the part of t cell activation process.The inhibition that CD40L expresses on the T cell can inducing cell unresponsiveness or anergy.Therefore, handling back CD40L undisturbed expression on the T cell is the indication of normal t cell activation.Make with anti-CD 3 antibodies and to check the influence (Figure 12) that PCT expresses CD40L behind the treated cell-stimulating.The result of this analysis shows, for the treatment condition that multiplication capacity subsequently is eliminated, the CD40L of processed cell expresses and observed close parallel in untreated cell.
In a word, under the serious condition that reduces or suppress fully of propagation (seeing Fig. 8 and 9, present embodiment), the expression of earlier T cell-stimulating mark CD69 and IL-2 acceptor CD25 is still unaffected basically; And the CD40L level is parallel with untreated cell.Should be pointed out that CD69 i.e. transient expression on lymphocyte in case through antigen or mitogenesis stimulation, the continuation of CD69 is expressed needs new transcribing.Therefore, observe high CD69 level in treated non-proliferative cell, this has further supported to handle reversibly this opinion of inhibition of gene expression.The cytotoxic T cell function
