Definitions
- the present invention is directed to a method for intracellular binding of specific molecules, preferably proteins. More specfically, this method involves the intracellular expression and subsequent use of antibodies specific for a desired molecule.
- HIV human immunodeficiency virus
- mammalian cells for the preparation of viral encoded proteins including structrual proteins and regulatory enzymes.
- Human T-cell Leukemia virus type 1 or 2 (HTLV-1 or 2) produce tumors in infected individuals as a result of viral expression.
- HTLV-1 or 2 Human T-cell Leukemia virus type 1 or 2
- Therapeutic strategies have included the development of drugs to target the undesired proteins, means of intercellular blocking of such proteins, for example, soluble CD4, and the use of drugs which will selectively kill cells expressing the undesired proteins.
- Another method of treatment that has been suggested is the transfer of genetic materials into cell.
- genetic materials for example, by receptor mediated gene delivery, transkaryotic implantation and viral shuttle vectors such as retroviral gene transfer.
- transkaryotic implantation and viral shuttle vectors such as retroviral gene transfer.
- viral shuttle vectors such as retroviral gene transfer.
- gene therapy cells which are either deficient in a protein or produce a dysfunctional protein are hoped to be mended by introducing into the cell DNA coding for the normal gene product.
- TIL tumor infiltrating lymphocytes
- a major impediment to the development of effective gene inhibition protocols using such antisense RNA or ribozymes is the ability to achieve a high level of expression of the inhibitor encoding DNA template in the transformed cells and this may also be a potential problem for using dominant negative mutants because of the competitive nature of the inhibition.
- an undesired molecule (sometimes referred to as a target molecule or target antigen), preferably a protein.
- This method comprises the intracellular expression of an antibody capable of binding to the target.
- a DNA sequence containing a sufficient number of nucleotides coding for the portion of an antibody capable of binding to the target operably linked to a promoter that will permit expression of the antibody in the cell(s) of interest (antibody cassette) is delivered to a cell.
- the "antibody gene" of the antibody cassette would utilize a cDNA encoding heavy chain variable (V H ) and light chain variable (V L ) domains of an antibody which can be connected at the DNA level by an appropriate oligonucleotide as a bridge of the two variable domains, which on translation, form a single polypeptide (referred to as a single chain variable fragment (sFv)) capable of binding to a target such as a protein.
- V H heavy chain variable
- V L light chain variable domains of an antibody which can be connected at the DNA level by an appropriate oligonucleotide as a bridge of the two variable domains, which on translation, form a single polypeptide (referred to as a single chain variable fragment (sFv)) capable of binding to a target such as a protein.
- the antibody gene does not encode an operable secretory sequence and thus the expressed antibody remains within the cell.
- a nucleotide sequence encoding an intracellular localization leader is also used.
- Preferred cell targets are retrovirally infected cells such as HIV infected cells, where the targets are the virally encoded protein.
- the targets are the virally encoded protein.
- an antibody cocktail i.e. mixture of antibodies
- Another preferred target includes oncogenes such as trans-membrane growth factor receptors, receptors, growth factors, membrane associated guanine nucleotide binding proteins, etc.

- Figure 15 shows the synthesis of antibody-polylysine conjugates.
- Figure 16 are autoradiograms showing expression of the sFv F105 in SupT HlV-infected cells under varying concentration of tat protein.
- Figures 17A through 17D show FACS analysis of gp120 expression in CD4 SupT cells infected with HIV-1 and stably transduced with the F105 sFv.
- Figures 18A through 18D show surface CD4 expression in HIV-1 infected SupT cells transduced with sFv F105.
- Figure 19 shows the result of syncytia formation studies after infecting SupT svector cells or SupT sFv 105 cells with HIV-1.
- Figure 20 shows trans-activation of cells expressing a plasmid containing an HIV-1 LTR-CAT reporter transfected with Tat at varying concentrations.
- Figure 21 shows tat activity in the presence of three different tat antibodies.
- Figure 22 shows tat activity for the antibodies of Figure 21 at a different antibody concentration.
- the present invention is directed to a method of targeting a particular molecule (target molecule), preferably a protein such as an undesired protein.
- This method comprises the intracellular expression of an antibody which is capable of binding to a specific target (e.g. a target protein), wherein the antibody preferably does not contain sequences coding for its secretion.
- a specific target e.g. a target protein
- the term antibody refers to at least that portion of an immunoglobulin capable of selectively binding to a target such as a protein.
- the antibody is expressed from a DNA sequence which contains a sufficient number of nucleotides coding for the portion of an antibody capable of binding to the target, referred to herein as the antibody gene.
- the gene is operably linked to a promoter that will permit expression of the antibody in the cell(s) of interest.
- Promoters are well known in the art and can readily be selected depending on what cell type you wish to target.
- inducable promoters which are also well known in the art, in some embodiments are preferred.
- the entire sequence of antibody gene and promoter is described herein as an antibody cassette.
- the cassette is delivered to the cell by any of a number of means described below, which permit intracellular delivery of a gene.
- the cassette results in the intracellular expression of the antibody.
- the expressed antibody can then bind to the target antigen.
- Almost any kind of biologic molecule can serve as an antigen, for example, intermediate metabolites, sugars, lipids, autacoids, and hormones as well as macromolecules such as complex carbohydrates, phospholipids, nucleic acids such as RNA and DNA, and proteins.
- the skilled artisan can generate antibodies that will specifically bind to both the small molecules and macromolecules.
- the preferred target molecules include proteins, RNA, DNA and haptens. More preferably, the targets are proteins, RNA and DNA. Still more preferably, the target is a protein.
- oncogenes Overexpression of a number of oncogenes has been reported to be associated with malignant cellular transformation. For example, amplification of myc has been reported in COLO 320 colon carcinoma cell cultures, the SKBR3 breast carcinoma cell line and in lung carcinoma cell lines. Amplification of N-myc has been reported in neuroblastoma cell lines and retinoblastoma. Amplification of c-abl, c-myb, and other oncogenes have also been reported to be associated with malignant transformation. See, chapter 12 "Human Oncogenes" pp 487-543, RNA Tumor Viruses. Molecular Biolo ⁇ v of Tumor Viruses. 2nd Ed., Weiss, R. et al., Ed. (Cold Spring Harbor Laboratory (1985)).
- PDGF denotes platelet-derived growth factor, FGF fibroblast growth factor, EGF epidermal growth factor, and M-CSF mononuclear-phagocyte growth factor.
- oncogenes (sometimes referred to as ones), some oncogenes undergo a mutation from a proto-onc (normal gene for normal protein) to an one (gene whose protein can cause malignant transformation) which appears to result in malignant transformation of
- the family includes src, fgr, yes, lck, hck, fyn, lyn, and tkl.
- the virus can be either RNA or DNA viruses.
- RNA viruses retroviruses are typically classified as being part of one of three subfamilies, namely oncoviruses, spumaviruses and lentiviruses. Infection by oncoviruses is typically associated with malignant disorders.
- the viral proteins encoded include the gag, pol, and envelope.
- the virus contains oncogenes which encode a protein capable of malignant transformation of a cell in culture. Lentiviruses result in infection which is generally slow and cause chronic debilitating diseases after a long latency period.
- genes encoding the gag, pol and envelope structural proteins they also encode a variety of regulatory proteins.
- the virus's RNA and/or DNA can take over the cell machinery to produce the virally encoded protein.
- HTLV-1 is a retrovirus which is the etiological agent of adult T-cell leukemia-lymphoma (ATLL), an aggressive neoplasm of CD4 + T-cells [Poiesz, B.J., et al., Proc. Natl. Acad. Sci. 77:7415-7419 (1980)].
- ATLL adult T-cell leukemia-lymphoma
- CD4 + T-cells an aggressive neoplasm of CD4 + T-cells
- Epstein-Barr Virus has been linked to a number of tumors such as selected outbreaks of Burkitt's lymphoma, nasopharygeal cancer and B- lymphomas in immunosuppressed individuals, [zur Hausen, H., Science
- Hepatitis B virus has been linked to hepatocellular cancer [zur Hausen, Science, supra].
- the X open reading frame of the virus seems to be involved [Ibid]. Accordingly, an antibody that targets this region or expression products from this region would be preferable in the present method.
- Papillomaviruses have been linked to anogenital cancer [Ibid], in these viruses the E6 and E7 genes appear to be involved and would be good targets.
- nucleic acid such as a DNA provirus
- RNA of the virus By intracellular binding to nucleic acid one can prevent or inhibit the virus's integration into the cell.
- RNA of the virus By binding to the RNA of the virus one can interfere with its expression of viral protein.
- Anti-nucleotide antibodies have been extensively studied [Van Es, J.H., et al., J. of lmmun. 149:2234-2240 (1992); Brigido, M.M. et al., J. of Immun. 150:469-479 (1993); Stollar, B.D., et al., Proc. Natl. Acad. Sci. USA 83:4469-4473 (1986); Eilat, D., et al., J. of Immun. 141 :1745- 1753 (1988); Brigido, M.M., et al., J. of Immun. 146:2005-2009 (1991 )] and the antibodies share the same basic features.
- antibodies can be produced and/or screened by standard techniques such as using a nucleotide sequence such as RNA to screen a library containing antibodies [Tsai, D.E., et al., J. of Immun. 150: 1 137- 1 145 (1993); Okano, Y., et al., J. of Immun. 149:1093-1098 (1992); Tsai, D.E., Proc. Natl. Acad. Sci. USA 89:8864-8868 (1992).
- a nucleotide sequence such as RNA
- the TAR element of the primate immunodeficiency viruses For example, the TAR element of the primate immunodeficiency viruses. This nucleic acid sequence is present in the 5' LTR and is responsive to tat resulting in enhanced expression of viral protein.
- a viral envelope protein e.g. HIV gp160
- a viral envelope protein e.g. HIV gp160
- the capsid protein e.g. the HIV capsid protein
- myristic acid is involved in the attachment of the capsid precursor protein to the inner surface of cells.
- the provirus is not infectious.
- binding to a protein that has a significant external domain can hinder the effect of the protein.
- proteins such as surface receptors, transmembrane proteins, etc. are processed through the endoplasmic reticulum (sometimes referred to as ER)-Golgi apparatus.
- examples of such proteins include neu, envelope glycoproteins such as those of the primate lentiviruses, e.g., HIV-1 or HIV-2.
- antibodies that can be delivered to such a region of the cell and be specific for a particular protein, one can disrupt the function of such protein without disrupting other cellular functions.
- the PDGF-/2 and FGF-like factors produced by sis and int-2 pass through the ER. These factors are involved in many cancers.
- MHC class I and class II molecules are important in the immune systems recognition of antigens.
- HIV-1 envelope gene directs the synthesis of a precursor polyglycoprotein termed gp160.
- This protein is modified by addition of multiple N-linked sugars as it enters the endoplasmic reticulum
- glycosylated envelope protein precursor is then cleaved within the Golgi apparatus to yield a mature envelope protein comprised of an exterior giycoprotein, gp120, and a transmembrane protein, gp41 [Willey, Cell Biol., supra; Stein, B.S., et al., J. Biol. Chem.
- the envelope giycoprotein complex is anchored to the virion envelope and infects cell membranes by gp41 through non-covalent interactions [DiMarzo- Veronese, Science, supra; Gelderblom, H.R., et al., Lancet //:1016-1017 (1985)].
- the fusion of viral and host cell membranes allows virus entry
- the fusogenic domain of the gp120/gp41 complex is thought to reside at the amino terminus of gp41 because this region exhibits sequence homology with a fusogenic domain of other viral proteins [Gallaher, W.R., Cell 50:327-328 (1987)]; Gonzalez-Scarano, F., AIDS Res. Hum. Retrovir. 3:245-252 (1987)] and because mutations in this region inactivate the virus and prevent viral fusion [Kowalski, M., et al., Science 237:1351-1355 (1987); Kowalski, M., et al., J. Virol. 65:281-291 (1991 ); McCune, J.M., et al., Cell 53:55-
- the uncleaved gp160 is delivered to lysosomes for degradation.
- the cleavage process normally is relatively inefficient.
- the method of using intracellular antibodies to bind to the newly synthesized gp160 in the lumen of the endoplasmic reticulum and inhibit its transport to the Golgi apparatus greatly reduces the amount of protein available for cleavage to gp120 and gp41. Accordingly, the viral particles produced have greatly diminished amounts of gp120 and gp41 on their surface. Such particles are not considered as infectious.
- HIV-1 gp160/120/41 proteins is exemplary of other envelope proteins and processed proteins. The same techniques used herein can be adapted by known techniques based upon the present disclosure. Additionally, the envelope protein of the immunodeficiency viruses has been implicated in the other aspects of the disease [DeRossi, A., et al., Proc. Natl. Acad. Sci. 83:4297-4301 (1986)].
- HIV infection of cell cultures typically generates an acute and/or chronic infection. In both cases, virus is produced and becomes released by budding at the cellular membrane.
- An acute infection is typically characterized by a cytopathic effect manifested by vacuolization of cells and formation of syncytia and consequently cell lysis [Laurent-Crawford, Virol. 185:829-839 (1991 )].
- tissue cultures the cytopathic effects of HIV-1 consist of multinucleated giant cell (syncytium) formation and the lysis of single cells. [Popovic, M., Science 224:497-500 (1984); Somasundarin, M., et al., J. Virol. 61 :3114-3119 (1987)].
- Syncytium formation is mediated solely by the HIV-1 envelope protein expressed on the infected cell surface [Sodroski, J., et al.. Nature
- the envelope binds to the CD4 receptor present on adjacent cells and then, via a fusion reaction agnalogous to that involved in virus entry, the apposed cell membranes are fused so that heterokaryons are formed.
- Single cell lysis also depends on efficient membrane fusion induced by the envelope glycoproteins as some mutations in the gp41 amino terminus result in replication competent viruses that are attenuated for both syncytium formation and single cell lysis [Kowalski, M.L., et al., J. Virol. 65, supra (1991 )]. It has also been reported that amino acid changes in gp120 which effect processing of the gp160 precursor can decrease single cell lysis [Stevenson, M., et al., J. Virol.
- HIV envelope giycoprotein has been implicated by a number of other individuals in explaining the onset of the associated immunodeficiency infected individuals.
- Siliciano, R.F., et al., [Cell 54:561-575 (1988)] have shown that a subset of CD4 + gp120-specific clone manifest cytolytic activity and lyse uninfected autologous CD4 + T- cells in the presence of gp120 in a process that is strictly dependent upon
- CD4 mediated uptake of gp120 by T- cells Since gp120 can be shed from infected cells, this CD4 dependent autocytolytic mechanism can contribute to the profound depletion of CD4+ T-cells in AIDS patients. Kion, T.A., et al., [Science 253:1138-1 140 (1991 )] and Hoffman, G.W., et al., [Proc. Natl. Acad. Sci. USA 88:3060-3064 (1991 )] have shown that an autoimmune idiotypic network develops in HIV-1 infections which leads to the development of autoimmune antibodies that destroy CD4 + T- cells. This autoimmune mechanism develops because of the sequence homologies between gp120 and class II MHC molecules [Young, J.A.T, Nature 333:215 (1988)]. The immunosuppresive effects of gp 120 on the
- CD4 + T-cell proliferation to antigenic stimulus have been demonstrated [Hoxie, J.A., et al., Science 234:1 123-1 127 (1986); Diamond, D.C., et al., J. Immunol. 141 :3715-3717 (1988); Gurley, R.J., et al., Proc. Natl. Acad. Sci. USA 86:1993-1997 (1989); Crise, B., et al., J. Virol. 66:2296-2301 (1992)].
- immunodeficiency diseases such as HIV-1 may affect major histocompatibility complex II restricted antigen recognition independent of CD4 + T-cell loss.
- gp120 In rodent neurons, gp120 has been shown to cause an increase in intracellular calcium and neuronal toxicity [Dreyer, E.B., et al., Science 248:364-367 (1990)], an effect which might be mediated by activation of the nuclear endonuclease.
- activation induced T-cell death, or apoptosis has also been proposed as occurring in vivo and accounting for the progressive depletion of CD4 + T-cells that leads to AIDS [Groux, H., et al., J. Exp. Med. 175:331-340 (1992); Meyaard, L., et al., Science 257:217-219 (1992)].
- the envelope giycoprotein can act as a superantigen binding only the variable- ? region of the T-cell antigen receptor, thereby inducing massive stimulation and expansion of such T- cells, followed by deletion or anergy. Pantaleo, G., et al., N. Eng. J. of
- an antibody to its target for example, the antibody to the envelope giycoprotein or the antibody to HIV tat protein
- results in an antibody that binds the target e.g. envelope giycoprotein or tat protein, respectively, in the cell and prevents further processing.
- the present method is highly specific and does not adversely affect cellular functioning.
- a mutant envelope protein that contains a single point mutation that abolishes the protein's ability to bind to this antibody will be processed normally in cells that constitutively express the protein.
- single chain antibodies to other proteins will not affect the processing of the envelope protein.
- the present methodology permits using an antibody specific to a particular protein and results in a process that can be tailored for specific diseases. Additionally, the methodology can be used prophylatically. One could even have the antibody under the control of a promoter that will be specifically activated by the target (e.g. an HIV LTR) thereby only turning the antibody on when the target is present. Other types of inducible promoters are known in the art and can be selected and used based upon the present disclosure.
- the use of the present antibodies do not affect the processing of other proteins.
- the antibody to the HIV envelope giycoprotein does not bind other envelope glycoproteins and does not prevent processing of such a protein.
- the processing of an unrelated envelope glycoproteins such as Bunyavirus envelope giycoprotein, will not be affected.
- cells that are subjected to the present method for example by intracellular delivery of an antibody to the envelope protein to produce a cell that constitutively expresses that antibody, results in a 1 ,000 to 10,000 fold reduction in the activity of viral particles produced when compared to virus from parental cells.

- the antibodies of the present invention can compete successfully with other molecules, they must retain at least about 75% of the binding effectiveness of the complete antibody to that target, i.e. having constant as well as variable regions. More preferably, it has at least 85% of the binding effectiveness of the complete antibody. Still more preferably, it has at least 90% of the binding effectiveness of the complete antibody.

- antibodies have the ability to recognize an almost limitless number of foreign molecules, in nature, antibodies recognize stuctures exterior to the cell. [Winter, G., et al., Nature 349:293 (1991 )]. Once synthesized, antibodies are secreted into the surrounding fluid or remain bound to the outer cell membrane [Klein, Immunology. Blackwell Scientific Publications, Cambridge, MA 1990]). We have found a means to express antibodies which retaining the ability to specifically bind to a target intracellularly.
- specificity for a particular target can be obtained by using the immune system, itself.
- the antigen binding or variable regions is formed by the interaction of the variable heavy (V H ) and variable light (V L ) domains at the amino termini of the chains.
- V H variable heavy
- V L variable light

- single domain antibodies also referred to as single domain antibodies
- one can use a gene coding for such an antibody fragment as long as it retains sufficient binding ability compared to the parent antibody.
- variable domains are each folded into a characteristic structure composed of nine strands of closely packed ?-sheets. The structure is maintained despite sequence variation in the V H and V L domains [Depreval, C, et al., J. Mol. Biol. 102:657 (1976); Padlan, E.A., Q. Rev. Biophys. 10:35 (1977)].
- Analysis of antibody primary sequence data has established the existence of two classes of variable region sequence. Hypervariable sequences and framework sequences [Kabat, E.A., et al., Sequences of Protein of Immunolo ⁇ ical Interests, 4th ed. U.S. Dept.
- the framework sequences are responsible for the correct yff-sheet folding of the V H and V L domains and for the interchain interactions that bring the domains together.
- Each variable domain contains three hypervariable sequences which appear as loops.
- the six hypervariable sequences of the variable region, three from the V H and three from the V L form the antigen binding site, are referred to as a complementarity determining region (CDRs).
- variable region genes for both the V H and V L chains of interest, it is possible to express these proteins in bacteria and rapidly test their function.

- the linker should be able to span the 3.5 nm distance between its points of fusion to the variable domains without distortion of the native Fv conformation.
- the amino acid residues constituting the linker must be such that it can span this distance and should be 5 amino acids or larger.
- the amino acids chosen also need to be selected so that the linker is hydrophilic so it does not get buried into the antibody.
- the linker should be at least about 10 residues in length. Still more preferably it should be about 15 residues. While the linker should not be too short, it also should not be too long as that can result in steric interference with the combining site. Thus, it preferably should be 25 residues or less.
- the linker (Gly-Gly-Gly-Gly-Ser) 3 (SEQ ID NO:1 ) is a preferred linker that is widely applicable to many antibodies as it provides sufficient flexibility.

- the immune system can prepare the antibody which will bind to a specific molecule such as a target protein by standard immunological techniques. For example, using the protein or an immunogenic fragment thereof or a peptide chemically synthesized based upon such protein. Any of these sequences can be conjugated, if desired, to keyhole limpet hemocyanin (KLH) and used to raise an antibody in animals such as a mice, rabbits, rats, and hamsters. Thereafter, the animals are sacrificed and their spleens are obtained. Monoclonal antibodies are produced by using standard fusion techniques for forming hybridoma cells. See, Kohler, G., et al. Nature 256:495 (1975).
- KLH keyhole limpet hemocyanin
- an antibody-producing cell i.e., spleen
- an immortal cell line such as a myeloma cell
- Another method for preparing antibodies is by in vitro immunization techniques, such as using spleen cells, e.g., a culture of murine spleen cells, injecting an antigen, and then screening for an antibody produced to said antigen. With this method, as little as 0.1 micrograms of antigen can be used, although about 1 microgram/milliliter is preferred.
- spleen cells are harvested, for example, mice spleen cells, and incubated at the desired amount, for example, 1 x 10 7 cells/milliliter, in medium plus with the desired antigen at a concentration typically around 1 microgram/milliliter. Thereafter, one of several adjuvants depending upon the results of the filter immunoplaque assay are added to the cell culture.

- the insoluble products of the enzymatic reaction are visualized as blue plaques on the membrane. These plaques are counted, for example, by using 25 times magnification. Nitrocellulose membrane of the microfilter plaques readily absorb a variety of antigens and the filtration unit used for the washing step is preferred because it facilitates the plaque assay.
- Cultures containing the antibodies of interest are grown and induced and the supernatants passed through a filter, for example, a 0.45 micromiter filter and then through a column, for example, an antigen affinity column or an anti-tag peptide column.
- the binding affinity is tested using a mini gel filtration technique. See, for example, Niedel, J., Biol. Chem. 256:9295 (1981 ).

- the F105 single chain antibody which is typically expressed in the ER, was reamplified, containing a new 5' primer that anneals to the framework 1 region of the antibody. It therefore does not contain the leader peptide but contains a strong initiation start signal with a extra methionine at the 5' end as a start codon.
- This primer has a Hindlll site at the 5' end, followed by the Ncol site containing the Met start codon.
- TTT-AAG-CTT-ACC-ATG-GCC-CAG-GTG-CAG-CTG-CAG-GAG-TCG-GG (SEQ ID NO:57) and codes for Met Ala Gin Val Gin Leu Gin Glu Ser Gly (SEQ ID NO:58).
- methionine which is right in the middle of the Ncol site, there is an additional amino acid, Ala.
- Ala At the carboxy end of the signal peptide for bacterial expression, there is an Ala-
- Met-Ala cleavage The cleavage into the periplasm occurs right after the second Ala and before the first amino acid of the framework. So, this is a verstaile primer that can be used or modified and used in many situations. For example, one can start with the Ncol site by the appropriate endonuclease and clone it into a bacterial expression vector. The same primer can be reused to amplify or to take the amplified material that still has the Hindlll site and digest it with Hindlll.
- one has a single chain antibody with the additional methionine as well as an Ala on the 5' end, that can be cloned into a vector, such as the pRC/CMV expression vector, transfected with lipofection, radiolabelled with S 35 methionine and immunoprecipitated with anti-kappa antibody.
- a vector such as the pRC/CMV expression vector
- S 35 methionine was used the technique and obtained expression of an antibody to envelope in the cytoplasm.
- One can use this basic strategy and modify the antibody to also have a localization signal to transport the expressed antibody to a desired target.
- a single chain antibody such as the tat and have it reamplified on the 5' end with a primer that anneals to the framework 1 region of the variable region and has a methionine residue for a start codon and an Hindlll site for cloning.
- This antibody gene is then reamplified for cloning, and expression in pRC/CMV.
- that antibody is further modified so that, in addition to using that new 5' primer for cytoplasmic expression, the C-terminus contains the SV40 nuclear localization signal.
- the antibody can be expressed in the cytoplasm and where we also used, for instance, the SV40 nuclear localization signal, and tranported into the nucleus.
- the negative controls include different kappa chains, that were amplified from the same myeloma.
- tat antibodies can inhibit tat activity.
- a plasmid containing HIV-1 LTR-CAT reporter as little as 0.01 ⁇ g of tat expressing plasmid can result in 25X trans-activation.
- the localization signals can be located anywhere on the antibody so long as the signal is exposed in the antibody and its placement does not disrupt the binding ability of the antibody. For example, it can be placed at the carboxy or amino terminus or even on the linker between the heavy and light chain of a sFv antibody, providing it satisfies the above conditions.
- the expressed antibody does not contain the entire constant region domains. We believe that it is in this region where there are specific sequences which help in the secretion of the antibody from the cell. For example, we have constructed a broadly neutralizing sFv antibody to an envelope giycoprotein that contains only six amino acids of the constant region which is not secreted in any large amount by the cell, whereas the unaltered Fab antibody to such protein is secreted. This type of design to leave out such sequences can readily be accomplished in the selection and omission of nucleotides coding for the antibody. Although a broadly neturalizing antibody was discussed in this example, the antibodies used do not have to be broadly neutralizing. Neutralization is not required, rather, the antibody needs to bind to the target. Thus, one preferably looks for a epitope on the molecule that is conserved and accessible.
- the use of intracellular retention sequences such as KDEL for the endoplasmic reticulum should keep most of the antibodies expressed within the cell.
- the secreted Fab can target the molecule at different intracellular locations as it is secreted.
- the Fab can also target any molecule that might have escaped from the cell, extracellularly.
- the Fab can also bind to gp120 on the free virion and stop it from infecting another CD4 receptor or an uninfected cell.
- the use of these F105 Fabs in HIV infected COS cells has inhibited synctia formation.
- the gene for the antibody can encompass genes for the heavy chain and light chain regions.
- the gene is operably linked to a promoter or promters which results in its expression. Promoters that will permit expression in mammalian cells are well known and include CMV, a viral LTR such as the rous sarcoma virus LTR, HIV-LTR, HTLV-1 LTR, the SV40 early promoter, E. coli lac UV5 promoter and the herpes simplex tk virus promoter. This DNA sequence is described as the antibody cassette.
- a cassette containing these antibody genes can be targeted to a particular cell by a number of techniques.
- the sFv genes coding for HIV antibodies, which would be preferably introduced into CD4 + T-cells.
- the techniques described can readily be used to introduce the antibody genes into other cells, preferably human cells.
- a mammalian expression vector such as a Herpes vector, an adenovirus vector or a pox vector, a retroviral vector, a plasmid bound to an antibody, etc.
- these vectors can be used to transduce cells by standard techniques well known to the skilled artisan.
- this cassette is introduced in the cell by using an HIV viral vector, which is defective in packaging HIV sequences, but will preferentially target HIV susceptable cells.
- a promoter that will differentially express the gene in the desired target cell.
- an HIV-LTR as a promoter where the target is HIV infected cells.
- the HIV viral proteins in the cell such as tat can result in enhanced expression of the antibody when compared to uninfected cells.
- one can transduce cells that are at greater risk for viral infection such as CD4 cells.
- the intracellular expression of the antibody permits it to bind the target. This disrupts the functioning of the target, e.g., a protein, including the undesired functioning.
- expressing the sFv of a broadly neutralizing antibody to envelope giycoprotein can intracellularly block the transport and interaction with the CD4 molecules of the HIV-1 giycoprotein, as well as the cleavage of the protein.
- KDEL endoplasmic retriculum retention signal
- the expression of these antibodies should not harm the cells.
- the "ligand" target antibody is not present the antibody can be designed so that it will degrade.
- the antibody to envelope giycoprotein with a KDEL retention sequence was degraded soon after synthesis unless HIV-1 envelope giycoprotein was present to form an antibody-ligand complex.
- the single chain antibody to the envelope giycoprotein expressed without the retention signal was not similarly degraded but rather could be detected after radiolabeling an immunoprecipitation with polyclonal antibody to human immunoglobulin K- chain or heavy chain in the transfected cells. In both instances, the transformed cells appear to have normal morphology and growth rates
- FIG. 4 shows transformed COS cells, which were established by neomycin selection expressing either the single chain antibody or the single chain with the KDEL sequence, which is retained in the endoplasmic retriculum.
- This antibody bound to the HIV-1 gp160 protein and could be coprecipitated with either anti-K or anti-gp120. Very little gp120 was detected even in a four hour chase sample from the sFv transformed cell while a fraction of gp120 was detected in the vector transformed cells and in a lesser portion in sFv KDEL transformed ceils (See, Figure 5).
- the expressed sFv antibody binds to the protein gp160 and prevents the gp160 protein from further processing.
- an antibody to gp41 would also be delivered to such a cell to target any gp160 protein that was cleaved.
- An alternative strategy is to have the expression of the antibody under the control of an inducible promoter.
- the promoter will be inducible by an effect of the target.
- a viral LTR such as an HIV LTR as a promoter.
- the HIV virus produces proteins, e.g. faf, which "turn on" the promoter.
- the sFv-KDEL product although rapidly degraded without target present, did not appear to be rapidly degraded when the HIV-1 giycoprotein was present.
- an sFv-KDEL band became visable in a polyacrylmide gel after radiolabeling and immunoprecipitation.
- This protein also coprecipitated with the HIV-1 giycoprotein although a small portion of gp120 was detected, which suggests an incomplete block to the giycoprotein transport possibly due to the rapid degredation of newly synthesized antibody before binding to the ligand.
- target protein also assists the antibody to fold to the correct conformational state.
- antibody-ligand complexes prevent the target from operating in its typical manner. For instance, cytopathic fusion mediated by the HIV-1 gp120/41 is inhibited in the cells. This is shown by cotransfecting CD4 + Hela cells with the HIV-1 giycoprotein expresser pSVIII env and sFv or sFv-KDEL plasmid
- DNAs at a ratio of 1 :5 or tranfecting the transformed cells with pSVIII were able to reach the cell surface.
- Cells having the intracellular antibody showed a significant reduction of synctium formation while no significant reduction of synctium formation was observed in cells transformed or transfected with the vector that did not express the antibody, which indicates that the intracellular antibody can inhibit the cytopathic fusion by blocking the transport of the HIV giycoprotein to the plasmid membrane and/or the interaction of the HIV-1 giycoprotein with the CD4 molecules on adjacent cells even if the sFv- gp120 complexes were able to reach the cell surface.
- infectious HIV-1 particles were produced from these intracellular antibody-containing cells.
- the cells expressing the intracellular antibody were transfected with infectious HIV-1 proviral DNA and the supernatants from the transfected cells can be used to infect the CD4 human lymphocyte SupT1.
- a dramatically slower kinetics of infections is observed in such cells when compared with that from vector- transformed cells, although comparable amounts of p24 activity from the supernatants of all these cells were observed which may indicate that non-infectious HIV-1 particles can be produced in the absence of HIV-1 giycoprotein.
- the SupT sFv105 cells maintain parental phenotype, can respond appropriately to external stimuli, are resistant to the cytopathic effects of
- HIV-1 infection and the infected cells produce HIV-1 virus particles that are markedly diminished in their infectivity.
- Antibodies to this protein are known and include C2003 which binds to a sequence in the C-terminal portion of the p66 component [Ibid]. This antibody also binds to HIV-2 [DeVico, A.L., AIDS Res & H. Retro. 5:51 -60 (1989)]. Such antibodies can be screened for from patient sera and antibodies cloned as described above.
- the tar element which is responsive to faf, is located at the 5' end of messenger viral RNA. tat binding to this far element has been shown to result in a derepression of tar inhibition of translation in vitro.
- the tar element increases transcription, initiation and also acts as an anti-attenuator of transcription elongation. By directing an antibody against the tar sequence, inhibition of tat binding will occur and there will be a dramatic decrease in transcription efficiency. This will ultimately result in an inhibition or reduction of virus production.
- Rev controls the synthesis of viral structural proteins, including the capsid protein, replicative enzymes and the envelope giycoprotein.
- the rev protein controls virion protein expression by controlling the cytoplasma accumulation of RNA species.
- small multiply spliced viral RNA species accumulate, in the presence of rev, full-length and partially spliced envelope giycoprotein messenger RNA's accumulate.
- Antibodies directed against the RRE should inhibit rev binding to RRE and therefore, inhibit the major biological effect of rev.
- the rev protein regulates the synthesis of capsid, replicative enzymes, and envelope giycoprotein production by regulating the accumulation of messenger RNA species from which they are made.
- Structural protein messenger RNA's require binding of rev protein to the folded RNA structure called RRE for transloeation from the nucleus to the cytoplasm. Inhibition of rev binding by an anti-rev antibody should prevent virus expression from infected cells.
- RRE folded RNA structure
- Such TAR or RRE antibodies can be synthesized using known technology based upon the disclosure. For example, one can screen an
- RNA library with an antibody to obtain the desired antibody RNA library with an antibody to obtain the desired antibody.
- human melanoma has been found to produce several proteins with angiogenic activity, including fibroblast growth factor (bFGF), transforming growth factor alpha (TGFa), and transforming growth factor beta.
- bFGF fibroblast growth factor
- TGFa transforming growth factor alpha
- beta transforming growth factor beta
- a "cocktail” approach i.e. mixture of antibodies
- a cocktail of antibodies to at least envelope giycoprotein and tat is preferred.
- Other cocktails include antibodies to reverse transeriptase, TAR, RRE, etc.
- Such "cocktails” can be administered together or by co-transfections. It is preferred that no more than about three proteins in the same intracellular region are targeted, preferably no more than about two. For example, targeting gp160 and gp41 at the endoplasmic reticulum.
- nucleus vs endoplasmic reticulum As long as another intracellular target is in a different cellular region, i.e. nucleus vs endoplasmic reticulum, it can also be targeted without having a detrimental effect on antibody production.
- One preferred cocktail of antibodies would be antibodies for at least one structural viral protein such as capsid or envelope and one for regulatory proteins such as HIV rev, tat, HTLV-1 or tax or for a nucleic acid sequence such as TAR or RRE.
- Another preferred cocktail would be of antibodies to the same target, but at various intracellular locations. This could be done using different localization sequences. Thus, if some target is not bound to the antibody at one location and, for instance, is further processed, it can be targeted at a subsequent location. For example, with the envelope giycoprotein one could use localization sequences to target the protein at a number of points in its processing path. Alternatively, one could use multiple antibodies to target different epitopes of molecules. For example, using one antibody to target the CD4 binding region of an envelope giycoprotein and a second antibody to target the fusogenic domain of gp41 .
- HIV encoded proteins one preferred vector would be to have at two antibodies to capsid or envelope proteins and at least one to a regulatory protein. For example, to gp160, gp41 , tat and rev. Another cocktail would include antibodies to both the viral mRNA and the protein it encodes.
- HIV encoded target proteins are nef, vpr and for HIV-1 vpu, and for HIV-2 vpx. More preferably, nef and vpu.

- the vpr protein has been found incorporated into the capsid virus.
- the vpu protein is located within the cytoplasm of cells and may be associated with sub-cellular organelles. Antibodies to these proteins can be made by the methodology described herein.

- mammals preferably humans, suffering from an ailment caused by the expression or overexpression of specific proteins.
- One delivers an effective amount of a gene capable of expressing the antibody under conditions which will permit its intracellular expression to cells susceptible to expression of the undesired target antigen.
- This method can be used as a prophylactic treatment to prevent or make it more difficult for such cells to be adversely effected by the undesired antigen, for example, by preventing processing of the protein, interaction by the undesired protein with other proteins, integration by the virus into the host cell, etc.
- one preferred target is proteins that are processed by the endoplasmic reticulum.

- polylysines having an average chain length of about 60 to 500 lysine monomers. More preferably, the polylysine has an average chain length of about 90 to 450 lysine monomers.
- ligation with the antibodies can be accomplished using SPDP.
- First dithiopyridine groups will be introduced into both antibody or polylysine by means of SPDP and then the groups in the polylysine can be reduced to give free sulfhydryl compounds, which upon mixing with the antibodies modified as described above, react to give the desired disulfide bond conjugates.

- mutant antibodies can be generated.
- the F105 single-chain antibody which contained the immunoglobulin heavy chain leader peptide, was initially cloned into pSL1180 cloning vector as described above. To prepare this antibody for CDR3 replacement, the following methodology was performed. Because the antibody had been cloned into a Ncol/Sphl site, removal of some stuffer DNA was required. Thus, the vector was digested with Spel and Nhel to remove the Not I site. Following self-ligation, colonies were selected that had this stuffer DNA removed by screening. The resultant plasmid contained the F105 single chain antibody with the leader peptide in reverse orientation with two unique restriction sites that flanked the heavy chain CDR3 region.

- the vector was digested with Eag I and Bst Ell and a library of CDR3 regions were cloned in.
- the resultant transformants were digested with PVU2 and mutant antibodies were distinguished from wild type by the change in pattern after PVU2 digestion.
- a unique PVU2 site exists in heavy chain CDR3, therefore, in the mutant antibodies, that site is destroyed. Thus, the pattern would be different from wild type which contained wild type CDR3 that contained the PVU2 site.

- One of the six mutants designated R had a CDR3 region which coded for (SEQ ID NO:74) Leu-Thr-Leu-lle-Ser-Ser-Arg-Leu-Arg-Leu-lle-Ala- Val-Arg-Met.
- a eukaryotic expression vector that is capable of producing high titers of human Fab fragments in COS-1 cells was also produced.
- This vector is based on the pRC/CMV vector described above, however, the Fd heavy chain and the light chain are cloned in tandem and each chain is under the control of a separate CMV promoter.
- the vector also conatins a neomycin gene for stable transfection.
- Figure 3 shows pulse chase of COS-1 cells transfected with a plasmid expressing Fab fragments of F105 heavy (H) and light (L) chains.
- the first three lanes are the cell lysate and the second set of three lanes are from the cell medium. The lanes for each set are at 2, 3 and 4 hours of incubation.
- cell lysates (I) and medium (M) were harvested after the indicated times of incubation and radioimmunoprecipitates were obtained with a mixture of anti-human lgG ⁇ and anti-human kappa chain antibodies.
- the pulse chase experiment shown in Figure 3 shows that high levels of Fab fragments of F105 are found in both intracellularly and in addition, the Fab fragments are actively secreted into the medium.
- Cell lysates and culture supernatants from these F105 Fab transfected COS-1 cells bind gp120 in an ELISA assay and both heavy and light chains can be readily immunoprecipitated with either anti-lgG, heavy chain (Fab H in Fig. 3) or anti-kappa chain antibody (Fab K in Fig. 3).
- a single chain antibody to the HIV-1 tat protein was generated as follows.
- the 5' forward V H primer consisted of a 55 base pair oligonucleotide with the following sequence:
- the reverse murine J H primer beginning at the 5' end had the following sequence:
- GCC CCAG (SEQ ID NO:50).
- V kappa primer For PCR amplification of the murine kappa chain, containing the intrachain linker for the production of a single chain antibody, the following V kappa primer was produced.
- the second reverse C kappa primer was used for amplification of the C kappa chain that contains an SV40 nuclear localization signal at its 3' end.
- the primer had the following sequence.
- This primer will anneal from Kabat positions 1 10 to 1 15 and is then followed by the SV40 nuclear localization signal having the following amino acid sequence:
- RNA isolated from anti-tat-lll hybridomas was used to produce cDNA produced by random primer annealing in a 25 ⁇ g reaction.
- Five to ten percent of the single stranded cDNA was combined with the V H primer and V j primer and PCR was performed as described in Example 1 .
- the annealing temperature for the PCR reaction was 56°C.
- V kappa primer containing the interchain linker was combined with either the C kappa primer alone, or the
- PCR For both light and heavy chain amplification, 30 rounds of PCR was used. These PCR products were gel purified on a 2% low melting point agarose gel. Because prior sequence analysis of the kappa chain showed an internal BstE-ll site, a multistep cloning procedure was necessary. First, the heavy chain PCR product was Klenow kinase treated to repair the ends and assure that blunt ends were produced. The heavy chain fragment was then digested with Xbal. Likewise, the two different kappa chain constructs, with and without the SV40 nuclear localization signal, were Klenow kinase treated followed by digestion with Xho1.
- Equal molar amounts of these two fragments were mixed with the PSK+ vector that had been digested with Xbal and Xhol. This allowed for sticky end cloning at the extreme 5' and 3' ends, and blunt end cloning between the two PCR products.
- plasmid DNA was digested with BstE-ll and the approximately 120 base pair BstE- II fragment was recovered and recloned into the same vector. This was necessary to remove extraneous nucleotides at the blunt end site.
- Several clones were obtained and the orientation of the BstE-ll fragment was confirmed by PCR amplification using either the V H , V kappa primers or V kappa , kappa primers set forth above.
- an Xball/Apal fragment was obtained from the PSK + vector and cloned into the PRC-CMV vector which had been digested with the same restriction enzymes.
- the single chain antibody was reamplified with a new 3' primer to clone into the P-10-1 phagemid vector. Together with the original V H primer, a new reversed
- a second anti-faf sFv which is similar to the above-described tat antibody except that it has a ER localization leader sequence was constructed as follows:
- V H and V L domains of a murine anti-HIV-1 faf hybridoma cell line were cloned and DNA sequenced as described.
- V L primer corresponding to the 5' end sequence of the V L , 5'-GAGCTCGTGCTCAC(C/A)CA(G/A)(T/A)CTCCA-3' (SEQ ID NO:77), and a reverse Ck primer (P-Ck) corresponding to the beginning of the constant region of kappa chain with a stop codon, 5'-GGGTCTAGAC

- Figure 8 shows sFv105-KDEL specific binding to the HIV-1 giycoprotein in cells by autoradiograms of polyacrylamide gels showing that sFv105-KDEL protein is coprecipitated with the HIV-1 giycoprotein.
- Lane 1 shows lysates of mock transfected COS-1 cells precipitated with a mixture of anti-gp120 and anti-kappa chain antisera.

- Lane 3 was precipitated with an anti-kappa chain antiserum.
- Lane 4 shows lysate of COS sFv105- KDEL cells precipitated with a mixture of anti-gp120 and anti-kappa chain antisera.
- the amount of sFv105-KDEL protein precipitated by an anti- human kappa chain antibody is increased by the presence of gp160.
- the gp160 protein present in the COS sFv105-KDEL cells is also precipitated by an anti-kappa chain antibody.
- Antiserum that express gp160 is similar to the distribution of the sFv105 protein in COS sFv105 cells ( Figure 5B). Evidently, the sFv105-KDEL protein is stabilized by binding of gp160.
- the ability of cells that express a single chain antibody capable of binding sFv105 to inhibit processing of a mutant of the env protein was examined.
- the COS sFV105 cells were transfected with a plasmid that expresses a mutant of the envelope protein in which glutamic acid has been substituted with glutamine at position 370. This mutation has been previously shown to eliminate detectable binding of the envelope protein by the sFv105 parental antibody [Thali, M.C., et al., J.
- the COS-sFv cells were infected with 5 M.O.I of vaccinia virus encoding T7 polymerase for 2 hours and then transfected with 10 ⁇ g of plasmid DNAs PTV-G1-G2, which contains the genes of G1 and G2 glycoproteins of Punta Toro virus under the control of T7 promoter (Chen, S.Y., et al., J. Virol., supra], or plasmid T7-HA, which contains the HA gene of the WSN strain of influenza A virus under the control of the T7 promoter [Chen, supra].
- the cells were then pulse-labelled with 35 S-cysteine for 30 minutes and chased for 4 hours.
- Lane 3 and 4 the lysates of PTV G1-G2 transfected cells 3 immunoprecipitated with anti-PTV giycoprotein (Chen, supra) (Lane 3) or anti-kappa chain (Lane 4).
- Figure 9 also shows that the processing of the Punta toto envelope protein is not affected by the expression of the sFv105 antibody (lanes 3-6).
- the ability of other single chain antibodies that do not bind to gp160 to interfere with processing of the envelope protein was examined. Two different single chain antibodies were used. One such antibody is the single chain antibody derived from a murine monoclonal antibody that recognizes the HIV-1 tat protein. This anti-faf single chain antibody has been altered from the tat antibody's normal intracellular target to have a leader sequence which will target the ER. This antibody is also stably retained intracellulary in COS cells and is not secreted into the medium in a transient expression assay. The processing of gp160 to gp120 in COS cells was unaffected by cotransfection of a plasmid which expressed the HIV-1 giycoprotein with the plasmid that expressed the anti-faf sFv.
- an anti-immunoglobulin antisera that precipitates the anti-faf sFv does not coprecipitate the HIV-1 envelope protein (See Figure 10).
- Figure 10 shows that an intracellularly retained anti-faf sFv does not bind HIV-1 giycoprotein.
- the COS cells were cotransfected with 10 ⁇ g of pSVIIIenv and 10 ⁇ g of pRC/CMV-sFvfaf plasmid DNA, pulse-labelled with
- the proteins were immunoprecipitated with antimouse immunoglobulin antisera (Lane 1 ) or sheep anti-gp120 (Lane 2) and analyzed by SDS-PAGE.
- the six mutants of sFv105 produced in which all of the amino acids in the CDR3 region of the heavy chain were replaced by random amino acids and which do not bind the protein were also used.
- the processing of gp160 to gp120 in COS cells was unaffected by cotransfection of the plasmids that express these mutant proteins.
- the anti-immunoglobulin antisera did not coprecipitate the HIV-1 envelope protein.
- the ability of the sFv105 and sFv105-KDEL proteins to inhibit the function of the envelope protein was determined by measurement of the ability of cells transfected with the envelope gene to induce syncytium formation of CD4 + cells.
- the parental COS vector cells as well as the COS sFv105 and COS sFv105-KDEL cells were transfected with a plasmid that expresses a functional envelope giycoprotein.
- the cells were mixed at a ratio of about 1 to 10 with a human CD4 + T cell line, SupT1 , that is susceptible to envelope mediated fusion.
- CD4 + Hela cells were cotransfected with 3 ⁇ g of pSFIIIer/v and 15 ⁇ g of vector or pCMV-sFv or pCMV-sFv-KDEL. Synctia were counted 30 hours post-tranfection. The transformed cells were transfected with 3 ⁇ g of pSVIIIenv which were incubated for 48 hours, then rinsed in PBS and incubated with 50 mM EDTA at 37°C for 40 minutes.
- the cells were removed from the plate, washed with PBS, and resuspended in 2 ml of DMEM supplemented with 10% fetal calf serum. The cells were then added with about 2 x 10 6 SupTI lymphocytes and incubated at 37°C for 12 hours and synctia was scored.
- COS, COS sFv105 and COS sFv105-KDEL cells were transfected with 5 ⁇ g infectious pSVIIIB DNA. The supernatants from the cells were harvested at day 4 of transfection and 1 ml of each of the supernatants was then inoculated with about 2 x 10 6 SupTI cells for 12 hours.
- the SupTI cells were then washed with DMEM twice and placed in the RPMI medium supplemented with 10% fetal bovine serum after 12 hours. The supernatants of the SupTI cells were then harvested and the production of viral particles was measured by using a sensitive radioimmunoassay serum for the HIV-1 p24 capsid antigen protein (DuPont-NEN Inc.) following manufacturer's instructions.
- Figure 7 shows a significant reduction of synctium formation in the CD4 +
- HeLa cells and the transformed COS cells expressing sFv or sFv-KDEL The percentage of the values of synctia observed in the CD4 + HeLa cells or the vector transformed cells transfected with pSVIII env are shown.
- COS vector, COS sFv105, and COS sFv105-KDEL cells were transfected with a plasmid that contains a copy of the entire viral genome [Fisher, A.G., et al., Nature 316:262-265 (1985); Helseth, E.M., et al., J. Virol. 64:2416-2420 (1990)].
- the virus in the culture supernatant fluids was used to initiate infection of the sensitive indicator cell line SupTI .
- the supernatants of all three transfected cells lines were shown to contain similar amounts of the viral capsid protein, p24.
- Figure 11 shows that virus replication in SupTI cells initiated by supernatants from the transfected COS sFV105 or COS sFv105-KDEI cells is delayed about 5 days relative to that initated by supernatants from the tranfected COS sFv105 or COS sFV105-KDEL cells is delayed about 5 days relative to that initiated by virus produced by a control COS-1 cell line that contains the vector but not the sFV105 sequences.
- Figure 1 1 shows virus yield by the infected SupTI cells.
- the infectious pSVIIIB DNA is an infectious HIV-1 proviral DNA of the HXBc2 strain [Fisher, A.G., et al. Nature 315:262-265 (1985)].
- the sFv105 or sFv105-KDEL or vector transformed cells were transfected with 5 ⁇ g of pSVIIIB plasmid DNA containing an infectious HIV-1 proviral DNA of the HXBc2 strain. After 4 days of transfection, the supernatants from the transfected cells were inoculated with SupTi cells for 16 hours and then washed, placed in fresh medium, monitored for concentration of viral capsid p24 protein by gag p24 activity in the culture medium. The medium amounts detected from the supernatants of transfected cells were 1.2 ng/ml (vector-COS), 1.0 ng/ml (COS sFv105), and 1.4 ng (COS sFv105-KDEL) respectively.
- Figure 1 1 represent the results obtained using supernatants harvested from the COS control cell line that contains the vector alone (0), a COS cell line that consitutively expresses the sFv105 protein (D), and a COS cell line that expresses the sFv105-KDEL protein ( ⁇ ).
- Figure 12 shows virus titer by syncytium formation in SupTI cells.
- the transformed COS vector and COS-sFv105 cells were transfected with 4 ⁇ g of pSVIIIB plasmid DNA containing an infectious HIV-1 proviral DNA of the HXBc2 strain [Ratner, supra]. After 48 hours of transfection, the supernatants from the transfected cells were harvested and used in serial dilutions to infect SupTI cells for 16 hours and then washed. After 8 days, syncytia were counted.
- Data are number of wells positive for syncytia/number of wells counted. Five high power fields (HPF) were counted in each well. One or more syncytia in five HPF counts as ( + ) for the dilution.
- the delay in replication of virus produced by COS sFv105 cells and the decrease in infectious titer is attributed to low infectivity of the virus relative to that of virus produced by the control cell line.
- the results of these experiments demonstrate that cells can produce antibodies that function intracellularly.
- the antibody is stably expressed and retained in the endoplasmic reticulum and is not toxic to the cells.
- the antibody binds to the envelope protein within the cell and inhibits the maturation and function of this critical virus protein.
- a trans-complementation assay was used, which uses two plasmids, one encoding rev and envelope proteins (pSVIIIenv) under control of HIV-1 LTR, and the other containing a HIV-1 provirus with a deletion in the en v gene (p XBen vCAT) and a chloramphenicol acetytransferase (CAT) gene replacing the nef gene [Helseth, J. Virol.
- Both plasmids were transfected into COS-1 cells and the supernatants from the ceils, which contained virus particles with single round infectivity, were used to infect parental SupT, SupT vector or SupT sFv105 cells.
- the CAT activity was determined from the lysates of the infected cells, which reflects the single-round infectivity of the virus particles.
- the expression of the sFv105 does not interfere with expression of several cell surface molecules.
- surface CD4 expression is normalized after HIV-1 infection in sFv105 producing SupT cells.
- FACS analysis on additional surface markers including CD3, CD5, CD7, CD8, ⁇ 2 M, CD20 and HLA-DR.
- CD3, CD5, CD7, CD8, ⁇ 2 M CD20
- HLA-DR HLA-DR
- Transduced cells are capable of responding to appropriate stimuli with increased levels of inducible proteins.
- PHA stimulation experiments comparing the levels of 3 H-thymidine incorporation between SupT vector and SupT sFv105 ceils were performed. After 6 hours of incubation with or without 8 mM PHA and labelling with 3 H-thymidine there was a greater than 10-fold increase in thymidine incorporation in both cell lines whereas unstimulated levels were equivalent (SupT vector - stimulated 1485 cpm/unstimulated 139 cpm; SupT sFv105 cells - stimulated 3330 cpm/unstimulated 263 cpm). Therefore these transduced cells appear to respond to the mitogenic response at equivalent levels.

The promoter and cell interdependence of this expression is shown in lane 2 of Fig. 13 where the CMV promoter is used. Many clones were screened and virtually non produced detectable antibody. Jurkat cells gave similar results.
