Describe in detail
The invention describes vaccine combination, described preparation of compositions method and medication, so that not dependence antigen or cause antigen such as polysaccharide (PS), polyhydric alcohol, polyamino acid and other organic polymer of faint immunne response usually of immunity antagonism T cell to be provided.Vaccine of the present invention has the effective immunological characteristic of typical PS albumen conjugate vaccines, but the phase be different from conjugate vaccines with needing, difference is need not significant covalency atom and connects target antigen such as PS or pod membrane organic polymer are connected to carrier protein.On the contrary, carry target antigen such as PS or pod membrane organic polymer with the carrier protein bag.For example, can form protein matrix by carrier protein self covalent cross-linking in the presence of soluble antigen such as PS or pod membrane organic polymer: these vaccines are known as protein matrix vaccines.Highly cross-linked each other carrier protein can form can capture antigen and promote antigen absorption and to producing the substrate of the stimulation of antibody in the immunocyte.Carrier protein substrate can be and seals antigenic " grid " form or antigen wherein is " rope " and protein or crosslinking protein complex are the forms of a series of " beading " of " pearl ".If carrier protein forms around the antigenic ring or the antigenic three dimensional network that tangles around antigen, then can make the carrier protein bag carry antigen.In addition, described carrier and antigen can be crosslinked, and is for example crosslinked by antigen chain and carrier protein are carried out in the chain.In the embodiment of phase need, described antigen and carrier protein right and wrong are covalently bound.This non-covalent connection can comprise hydrophobic interaction, ionization, model ylid bloom action or hydrogen bond.Non-covalent connection can comprise antigen and the non-covalent associating physical geometry of protein complex (seeing the metaphor of above " beading ").
Carrier protein need not self to carry out crosslinked the bag and carries antigen.For example also can antigen and albumen co-precipitation be wrapped carry antigen by mixed carrier albumen and antigen and precipitophore albumen in aqueous solution.Also can come to carry antigen from the chemical compound of antigen and carrier protein mixture (for example Alumen, sodium hexameta phosphate, poly-phosphorus piperazine or by hydrophobic or ionization drives that protein is had other polymer of affinity) by precipitation with the carrier protein bag.The method of precipitating proteins in this area be standardized and comprising, for example, (1) pH of change mixture, (2) change the ionic strength of solution by the concentration that increases or reduce inorganic salt in the mixture, (3) or toward mixture add trichloroacetic acid (TCA) or ammonium sulfate, (4) heating blends causes protein coagulating (promptly forming precipitation or gel), (5) in a certain way the protein in the chemical modification mixture it can not be dissolved and (6) with the ionizing radiation (ultraviolet of enough flux, gamma-rays or β ray) the irradiation protein solution cause proteinic crosslinked and/or the precipitation.
When using the pathogen protein clostridium, this vaccine is called albumen pod membrane matrix vaccines (PCMV).As described in an embodiment, prepare PCMV, it comprises based on pattern T cell dependent/non-dependent k antigen: poly--γ-D-glutamic acid (PGA) and alginic acid (alginate) and glucosan; PCMV with exemplary carrier protein DNI.PGA PCMV be easy to prepare in a large number and find its induce typical case in the immunne response of PGA albumen conjugate vaccines.Can in the presence of any target antigen, carry out the crosslinked vaccine of the present invention for preparing to any a lot of possible carrier proteins with any a lot of possible joints.This paper has discussed exemplary and preferred joint, carrier protein and target antigen.
Polysaccharide (PS) is the polymer of sugar.The PS that derives from pod membrane relates to the first antigen component (primary antigenic component) at the protective immunity of capsular bacterium pathogen, and these bacterial pathogens for example have Neisseria meningitidis (Neisseria meningitidi), streptococcus pneumoniae (Streptococcus pneumoniae), salmonella typhi (Salmonella typhi) and influenza B haemophilus (Haemophilus influenzae Type B).Use based on the immunity inoculation teenager of the vaccine of microorganism PS and adult and reducing success aspect the disease puzzlement, but proved for child of tender age (i.e. child below 24 months) protective immunity aspect effect is provided lower.Child of tender age's adaptive immune system is not all also reached maturity, and a little less than the immunogenicity of T cell dependent/non-dependent antigen such as pod membrane PS and can not in these young vaccine receptors, cause secular protective immune response (being that immunological memory is replied).
T cell dependent/non-dependent antigen such as PS can be converted into T cell dependence antigen by PS and proteinic chemical coupling; This chemical coupling process is called " puting together " and relates to the atom in the PS structure and be present in covalently bound formation between the side chain atom of " carrier " Argine Monohydrochloride.This " conjugate vaccines " more effectively promotes to induce B cell maturation and isotype conversion, causes the much higher antibody of level with correct anti-PS protectiveness overview (profile).Protection antibody has high-affinity to its PS antigen, normally immunoglobulin G (IgG) subclass, have the antibody of the Shou Qichang of complement fixation activity and opsonin effector activity.
Fig. 1 has shown the exemplary non-limiting approach of inducing anti-PS IgG immunne response about the conjugate between PS and the carrier protein tetanus toxoid.In this model, the B cell that has only displaying can discern the antibody receptor of PS combines with the PS protein conjugate.Therefore, carrier protein is incorporated in to the B cell surface that shows correct PS binding specificity.Albumen-PS complex is absorbed intramolecularly vacuole compartment by these B cells, and here carrier is subjected to protein degradation effect processing.Presenting in the ditch (presentation groove) of MHC II receptoroid (MHC-II) transported and loaded to the peptide that derives from protein carrier.This MHC-II-carrier peptides complex is showed in the surface of B cell.When the MHC-II-peptide complexes was discerned by TXi Baoshouti (TCR), the T cell was activated justacrine and is provided the cytokine of " assisting " for inducing the B cell differentiation.The B cell is quantitatively enlarged and is divided into " plasma cell " of ready-made secretory antibody.Initial IgM (IgM) is generated by plasma cell but the auxiliary antibody such as the IgG that causes plasma cell to carry out the classification conversion and generate other isotype classification of final T cell.This process continues along with the sudden change of plasma cell experience, and causing producing has the more antibody receptor of high-affinity to the PS protein conjugate.When antigen is eliminated, have only the plasma cell of high-affinity to be retained in PS protein conjugate activation remaining in the circulation.The continuation of the maturation process that plasmacytic T cell relies on causes plasma cell group's expansion, produces the IgG antibody-like of high-affinity.By measuring the level of anti-PS IgG antibody in the study subject of immunity inoculation such as human serum, can monitor the expansion situation at an easy rate.
Final ripe and transformation process causes Shou Qichang's and to the generation of the special memory B cell of PS.Memory B cell has unique characteristic, if promptly be exposed to PS then be activated immediately.Activation causes memory B cell propagation and produces anti-PS IgG fast.Occur in " secondary " memory immunne response that the activation that is exposed to the memory B cell in the PS antigen process for the second time is called " booster response " and shows Shou Qichang.Initial immunity can stimulate IgM antibody and some IgG production of antibodies.At secondary immunity, i.e. " reinforcement " when injection, be upset and produce a large amount of IgG by the memory cell of initial immunity sequencing, promptly remember immunne response.
T cell dependent/non-dependent antigen does not stimulate lasting immunity usually, i.e. IgG production of antibodies, but can stimulate more provisional IgM production of antibodies than poor efficiency.Thereby PS antigen does not produce the IgG booster response usually separately.Yet if carry out initial immunity with the PS protein conjugate, PS will produce booster response, because produced IgG by sequencing by the inductive memory cell of conjugate.Really, be considered to simulate the protective response that produces owing to the microorganism that is exposed to displaying PS through the intravital booster response of vaccinated animal or human; This secular memory is for being very crucial with the vaccine that works aspect the immune object in protection after the conjugate vaccines immunity inoculation several years.Therefore, the value of PS protein conjugate is (1), and they induce the ability of the antigenic high-level IgG of anti-PS, and they induce ability at the antigenic memory immunne response of PS (2).PS antigen does not show these characteristics usually thereby is semiprecious antigen.Cause at the development progress of the conjugate vaccines of a lot of bacterial diseases (wherein the immunne response to PS may be a protectiveness) slow at the difficulty aspect the synthetic conjugated antigen and their production cost.
Other T cell dependent/non-dependent antigen comprises the aminoacid homopolymer, as poly--γ-D-glutamic acid (PGA) and polyhydric alcohol.Really, most of biopolymers are T cell dependent/non-dependent antigen.Polymer is because the repeat property of its chemical constitution (epi-position) can be crosslinked with their B cell immunoglobulin (Ig) receptor of identification.Therefore polymer can activate the IgM that the B cell produces anti-polymer with the same mode of polysaccharide.For example, the aminoacid homopolymer, poly--γ-D-glutamic acid (PGA) of Bacillus anthracis (Bacillusanthracis) is the weak and antigenic pod membrane polymer of T cell dependent/non-dependent of immunogenicity.The vaccine of being made up of the PGA that puts together with protein carrier is a hyperimmunization originality, can induce anti-PGA IgG and PGA is had immunological memory.Therefore.Most polymers is reacting as PS aspect their immunogenicity, because they are can not be under the MHC-II background processed and show, therefore can not raise the auxiliary of T cell.In being called the polymer of acceptor interaction of Toll sample receptor (TLR), some naturally occurring and another classes find exception.In case be activated, TLR can come the inducing cell factor to produce and adaptive immune response is produced to change by host cell.Some PS and TLR part are covalently bound or be subjected to this part and pollute (contaminate).For example, lipopolysaccharide (LPS) be hyperimmunization originality, induce the PS of IgG and memory response; The fat A of LPS partly is the TLR part, can be responsible for immunological characteristic.
In another example, even have been found that their some immunological characteristics of not linking to each other with protein carrier and also represent conjugate vaccines of minority streptococcus pneumoniae PS, promptly they induce the isotype conversion to IgG.Recently, commercial polysaccharide vaccine Pneumovax-23, and from indivedual PS of streptococcus pneumoniae (Streptococcus pneumoniae) different strains, find to be polluted (Sen etc., J.Immunol.175:3084-3091,2005) by the TLR part.What these PS preparation this discovery can be interpreted as does not exist albumen to put together the following isotype conversion that can induce to IgG.These streptococcus pneumoniae PS induce macrophage secretion IL-6 and TNF-α.Yet the PS that extracts through being further purified by phenol extraction can not induce the macrophage secrete cytokines.In immune Research, a little less than the PS of extract with phenol immunogenicity and no longer induce anti-PS IgG.Therefore, extract with phenol is removed the pollution molecule that these abnormal immunes of being responsible for this PS preparation are learned characteristic.Polluting molecule seemingly provides the TLR part of activating macrophage TLR dependent cell factor responsibility.By extract with phenol being further purified of PS removed described pollution TLR part and caused PS to become T cell dependency fully.
Above example explanation PS antigen can play the effect as PS-albumen conjugated antigen and need not the covalently bound of protein and carbohydrate.Unfortunately, the TLR part is normally urged inflammation.For example, even the very little dosage of LPS also is deleterious.Therefore, though the TLR part is mixed the immunne response that may enlarge PS with PS, this method also may produce the vaccine tool reactionogenicity or that cause vaccine receptor ill symptoms.The conjugate vaccines technology has kept the optional method that is used to prepare the PS vaccine with required immunogenicity spectrum and safety.
Exploitation with PS-albumen conjugate vaccines has reduced the children disease burden that is caused by the aggressive bacterial pathogens widely.For these less vaccines of number comprise that anti-influenza B haemophilus (Haemophilus influenzae B Type) vaccine and some meningococcus and strains of streptococcus are that the market can be sold in developed country.These PS-albumen conjugate vaccines in developing country because too expensive and can't be at developing country's production and selling.For example, septivalency streptococcus pneumoniae conjugate vaccines that commerce can be sold is worth every approximately every $58 (2006 time dollar), and need take four doses.Only price just makes these vaccines beyond one's ability the people that developing country bears the disease burden for those.
Because being difficult to carry out low price, the related chemistry and the production and the purification cost of PS and carrier protein, traditional conjugate vaccines produce.Usually all need to have suitable purity puting together the former two, chemical reaction just is able to carry out with rational coupling efficiency.Usually, the coupling chemistry must prove effective to the various PS in uniqueness aspect selected PS and carrier protein chemical.This coupling chemistry is introduced functional group in PS, the latter can be connected with carrier protein through the ε amino side chain of lysine thereafter.The PS chemical modification of introducing these coupling group can destroy the epi-position on the PS and introduce new epi-position (for example, the epi-position relevant with the glycosyl of joint or modification), and its significance has only by conscientious careful immune analysis and could assess.In addition, for traditional PS-albumen conjugate vaccines, the type of the character of the size of PS, the PS molecule number that each protein carrier molecule is connected, selected carrier and connection chemistry can influence the immunogenicity of conjugate vaccines.Therefore, for example (wherein every kind of known serotype of 90+ all has different PS structure (Bentley etc. in pneumoccoccosis, PLOS Genetics 2 (3): e31 262-269,2006)) situation under, a kind of single conjugation methods may be not suitable for all serotype.Repeating to synthesize the conjugate vaccines that (reproduciblysynthesize) have repetition immunological characteristic (reproducible immunological property) relates to: the character of the size of PS, the PS molecule number that each carrier protein molecule is connected, selected carrier and the type that connects chemistry are carefully controlled, and this has increased the cost of making conjugate vaccines significantly.
The appearance of antibiotic resistance makes that the vaccine urgency is more outstanding safely and effectively to developing.Make widely available vaccine, especially for developing country, also need to make cost-effective vaccine.Make at from the multiple polysaccharide antigen of one or more bacterial species different serotypes put together the connection Seedling, in the immunization protocol the childhood period of merging to, this will simplify high-risk group's vaccine administration.Yet existing conjugate vaccines technology is not calculate, and therefore puts together connection Seedling (combination conjugate vaccine) and may popularize in developing country hardly.Really, even in the developed country that has set up powerful market, the Wyeth 7-valency short supply of puting together Pnu-Imune 23 has recently illustrated that how difficult the vaccine of producing and store the complicated conjugate vaccines synthetic technology of needs is.
In the embodiment of phase need, vaccine of the present invention is a multivalence pod membrane matrix vaccines (PCMV), and wherein a kind of or a plurality of bacterial capsule components are downloaded in the multivalence carrier protein substrate by bag.Preparation PCMV is easy to, because as the target antigen of one of parent material, for example pod membrane only needs suitable purity.For example, it also is impure (it carries proteinase activity on DNI) that Vedan gathers γ-D-glutamic acid (PGA), and as described herein, its behavior is fully as the T cell dependent/non-dependent antigen of being suspected (embodiment 1).All three kinds of PCMV preparations (protein and PGA ratio its more than 7 times scope different) in PGA be successful to participating in of PCMV.
Because the method for preparing vaccine of the present invention is without any need for the target antigen chemical knowledge of capsular polysaccharide for example, this method does not rely on the needs of the cross-linking chemistry that exploitation and target antigen and carrier protein chemistry can hold.Though some antigen still may interact with joint, the usefulness of this vaccine that should not detract, in any case because target antigen and carrier protein be not intended to crosslinkedly can expect to have the immunogen characteristic.In vaccine of the present invention, the crosslinked of target antigen and carrier protein is not to make vaccine effectively necessary.This and traditional conjugate vaccines form sharp contrast, are therefore hindered in its preparation and exploitation.The vaccine phase of the present invention need have at least, 1%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 98% and even 100% crosslinked carrier protein for example, and be no more than, for example 1%, 5%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90% target antigen and carrier protein are crosslinked.Ideally, be no more than 10% antigen and carrier protein is crosslinked and at least 50% carrier protein is crosslinked.
The method for preparing vaccine described herein do not cause target antigen for example the pod membrane polymer extensively modified.Antigen keeps same state usually, and possible modification is for example reduction (reduction) of reducing sugar for the PS pod membrane that the end at polymer chain carries this group.This small modification can not have influence on the immunogenicity of most of pod membrane PS, because the inner residue of polymer enriches 100-1000 doubly than terminal sugar.On the contrary, for traditional conjugate vaccines, the joint group need be introduced for example pod membrane polymer of antigen usually, as the covalently bound point of carrier protein.Need to use joint because a lot of antigen for example the pod membrane polymer not as the reactive group of the part of its structure for example carboxyl or amino.For example, joint chemistry is introduced destruction and because its new epi-position that generation is not expected in vaccine product with the immune cross-reactivity of host self epi-position the unknown that PS can cause the pod membrane epi-position.
Vaccine production method described herein is not as the conjugate vaccines technical sophistication, because its chemistry only relies on carrier protein (DNI for example, b subunit of cholera toxin, diphtheria toxin, diphtherotoxin, tetanus toxin fragment C or escherichia coli (Escherichia coli) beta galactosidase) cross-linking chemistry.For example,, do not influence crosslinked pattern or degree, cross-linking agent (for example glutaraldehyde) concentration that the two is controlled by employed protein, concentration more and is added though the pod membrane polymer influences crosslinking rate when mixing with DNI.These parameters be can easily adjust, thereby required time and the effort of preparation vaccine, cost saving reduced.
Can use the method for the PCMV of preparation described herein, together with for example any pod membrane polymer of any antigen or any have minority amino or do not have that amino polymer and any carrier protein that is crosslinked for example do not have can be by the carrier protein of the destructive critical epitopes of borohydride reduction effect.The carrier protein phase of using in method described herein need have (unblocked) of at least 2 lysine residues or opening and can carry out other crosslinked residue through chemical modification.Tetanus toxoid is a kind of possible carrier protein.This toxin detoxifies by using formaldehyde, and formaldehyde is and the proteinic amino reagent that reacts.The carrier protein that other needs phase comprises b subunit of cholera toxin (available from SBL Vaccin AB), diphtheria toxin, diphtherotoxin, tetanus toxin fragment C (available from SigmaAldrich), DNI or from the beta galactosidase (available from Sigma Aldrich) of escherichia coli (Escherichia coli).
Current multivalence conjugate vaccines passes through at first synthetic discrete conjugate vaccines, subsequently their mixing generation " mixture " conjugate vaccines are prepared (for example, Wyeth septivalency Pnu-Imune 23,
Figure A20078003754500361
).For example the pod membrane organic polymer is admixed together makes carrier protein crosslinked with for example glutaraldehyde subsequently by the antigen that chemistry is different, perhaps mix by distinguishing the specific vaccine of synthetic the present invention, the method that can use the present invention to prepare vaccine prepares polyvalent vaccine.This motility provides significant advantage for the method that the present invention prepares polyvalent vaccine.
The exemplary vaccine PCMV of the present invention who is discussed vaccine #1-3 in an embodiment, its performance is just like conjugate vaccines, although in fact these vaccines are not through expecting that the method that produces any covalent bond synthesizes, described covalent bond is at the atom that constitutes the PGA molecule and constitute between the proteic atom of DNI and form.Glutaraldehyde reacts with protein amino side chain by the amino representative of the ε of lysine residue single-mindedly.The PGA polymer does not have free amine group and only has not carboxylic side-chain with the glutaraldehyde reaction.Therefore, the immunne response that similar conjugate produced that is produced by PCMV shows that long PGA molecule is loaded in DNI cross linking of protein molecule substrate inside by molecule ground bag.
According to non-limiting pattern, the effect that described bag carries is to carry DNI albumen and PGA enters the B cell, and the B cell combines with this substrate by the Ig receptor of immunity identification PGA.In case absorbed by these B cells, described substrate is degraded in the mode similar to traditional conjugate vaccines, this can cause the generation of the DNI derived peptide of showing on the MHC-II of corresponding B cell molecule.Thereby attached amplification and the maturation that causes this B cell that help that this raises the T cell immediately becomes generation product IgG plasma cell and the memory cell special to PGA.Therefore, according to non-limiting pattern, but PCMV works to be similar to albumen-put together the pod membrane vaccine in immunity completely different, because PCMV lacks significantly covalently bound between carrier protein and the pod membrane polymer.
The vaccine of the present invention that comprises PCMV can be used for combination, for example is used for the department of pediatrics vaccine.In addition, vaccine of the present invention can be used for the inoculation antagonism, for example, pneumococcal infection, (A group and B group) streptococcal infection, influenza B haemophilus (Haemophilus influenzae TypeB) (" HiB ") infects, meningococcus (for example, Neisseria meningitidis (Neisseriameningitides)) infects, and (for example can be used as from gram negative bacteria, Pseudomonas aeruginosa (Pseudomonas aeruginosa), soil draws hot Frances Salmonella (Francisellatularensis) (Thirumalapura etc., J.Med.Microbiol.54:693-695,2005; Vinogradov and Perry, Carbohydr.Res.339:1643-1648,2004; Vinogradov etc., Carbohydr.Res.214:289-297,1991), shigella (Shigella species), Salmonella (Salmonella species), acinetobacter calcoaceticus (Acinetobacter species), bulkholderia cepasea (Burkholderia species) and escherichia coli (Escherichia coli)) the O antigen vaccine.
Vaccine of the present invention can prepare in the following manner: for example in the presence of target antigen described herein, use that any for example those make at joint described herein that any for example those are crosslinked at carrier protein described herein at one or more.If use a kind of target antigen, albumen substrate vaccine of the present invention then is considered to univalent vaccine.If use more than a kind of target antigen, albumen substrate vaccine of the present invention then is considered to polyvalent vaccine.If microorganism pod membrane polymer is a target antigen, albumen substrate vaccine of the present invention then is considered to albumen pod membrane matrix vaccines (PCMV).

Under room temperature, five reactions are not packed under the situation of glutaraldehyde having.When T=0, add the glutaraldehyde (G25) of 0.1mL 25% in the shown reaction.Thereafter per G25 and repetition that added other 0.1mL in 30 seconds reaches the G25 of 0.8mL altogether up to reaction shown in each.The molecule crosslinked situation of DNI of being undertaken by difunctional glutaraldehyde molecule can be by being observed visually, this is according to producing different turbidity and judging according to the insoluble particle sample " gel " (" gel " like particle) that following order is arranged: the highest and gel formation situation of turbidity, reaction 1>2>3>4, reaction 5 keeps fully transparent and solvable.After 1 hour, 0.5M sodium borate buffer liquid pH 9.3 (SBH) that 2mL contained the 1M sodium borohydride join in all six reactions, to reduce the Schiff's base that forms between DNI molecules of ammonia base side chain and difunctional glutaraldehyde molecule.Silicone defoaming agent (0.01mL) is joined each reaction to be formed with the foam in the control course of reaction.Reactant was preserved 72 hours in 4 ℃.Then all reactants were fully dialysed 48 hours with SP7.4.With the centrifugal insoluble substance and stand-by of removing of end product in 4 ℃ of preservations.
By using water miscible carbodiimide, EDAC (1-ethyl-3-(3-dimethylamino-propyl) carbodiimide) amino coupled with carboxyl and the BSA of PGA, to synthesize the traditional conjugate between bovine serum albumin (BSA) and PGA, step is as follows: the water that makes 5mL contain 30mg/mL BSA mixes with the NP7.5 that 1mL contains 134mg/mL PGA, add 50mg EDAC, allow reaction at room temperature to carry out 3 hours.Make to react on 4 ℃, only in SP7.4, dialysed 24 hours then in 4 ℃ with SP7.4 dialysis blocking-up in the 18 hours active group that contains the 1mM glycine.End-product is called as the PGA-BSA conjugate.
After synthetic and dialysis PCMV and control formulation, check the proteic molecularity of DNI confirming no matter whether to exist different content PGA, glutaraldehyde really and albumen taken place molecule crosslinked.By SDS (dodecyl sodium sulfate) polyacrylamide gel electrophoresis with the described crosslinked situation of the sero-fast Western blot of anti-PA monitoring PCMV and control formulation.As shown in Figure 2, before glutaraldehyde cross-linking, DNI albumen moves to the 84kDa place.Confirm that as the migration band of molecular weight PCVM1-PCMV3 (swimming lane 1-3) shows that DNI albumen is crosslinked widely greater than 220kDa.Do not exist DNI albumen crosslinked alone under the PGA to show same high molecular weight species (swimming lane 5) yet.On the contrary, mix with PGA but show the band that moves altogether with DNI or lower molecular weight kind (swimming lane 4) without the DNI that glutaraldehyde is handled.Therefore, as if be subjected to protease activity contact scar from the PGA preparation of Vedan (Taiwan) to DNI.Vedan PGA sample carries out electrophoresis in swimming lane 6, yet does not show the contaminating protein of high-caliber and anti-PA antiserum reaction, shows that observed band is the DNI derivative products of each reaction.
In addition, with PGA and one or more as antigenic streptococcus pneumoniae PS whether be used for probing into FLA (vibrio cholera (Vibrio cholerae) flagellin) be a kind of under the PCMV background than the better carrier protein of DNI.By measuring, estimate the effect of these carrier proteins with the resulting carrier protein usefulness of calculating based on albumen weight at IgG level and the carrier protein of PS and PGA of various PCMV immunity inoculations.
Can also prepare PCMV by not using bi-functional cross-linking agent directly to make amino and carboxyl carry out crosslinked method.Particularly, prepare PCMV with the amino and the carboxyl of carbodiimide chemistry by crosslinked carrier protein.This chemistry makes between the carboxyl of the primary amino radical of lysine side-chain and agedoite and glutamine side chain and forms peptide bond.Though amino major part is subjected to through the sealing of the toxoid of formaldehyde treated, formaldehyde fully not with carboxyl reaction.Therefore, the carbodiimide chemistry can be used for preparing PCMV with fluid toxoid, and described fluid toxoid can have resistance to glutaraldehyde cross-linking.Be easy to crosslinked situation is detected by SDS-PAGE.The existence that depends on the high-molecular-weight protein " stain " that cross-linking agent (as glutaraldehyde) adds show taken place crosslinked.

For the experiment shown in the table 2, in 50mM HEPES pH 7.5, carry out the reaction of 200 microlitres and make it at room temperature be incubated 2 hours.With the reaction of going out of 120mM hydroboration Na temper.Add glutaraldehyde to 64mM, use bovine serum albumin (BSA), use diphtheria toxin, diphtherotoxin, diphtheria toxoid and tetanus toxoid extremely, add PGA, add 6B and 23F type streptococcus pneumoniae PS with 4mg/mL with 13.4mg/mL with about 5mg/mL with 15mg/mL.
As shown in table 2, some albumen through formaldehyde treated (for example, diphtheria toxoid) can not be crosslinked well with glutaraldehyde, therefore, needs to use other cross-linking chemistry to prepare PCMV.Other protein carrier as tetanus toxoid can with glutaraldehyde cross-linking, but different with the crosslinking degree of unmodified protein such as diphtheria toxin, diphtherotoxin and bovine serum albumin.
The analysis of embodiment 2. immunity inoculations and anti-DNI and anti-PGA immunne response
The soluble product of adjustment form 1 described 5 reactions is to same protein concentration (based on the absorptance at its 280nm place).To be used for described all the immunity inoculation researchs of Fig. 2 from the BALB/c mouse in about 5-7 age in week of Charles River.Contrasted 4 and 5 with 20 μ g DNIs proteic dosage immunized mice by peritoneal injection with PCMV vaccine 1-3 and antigen preparation at the 0th day.At the 7th day all mices are carried out blood-letting, at the 10th day antigen preparation it is carried out booster immunization then with onesize dosage.The 17th day once more to the mice blood-letting, then at the 20th day once more to its booster immunization.Again mice was carried out blood-letting at the 30th day and this time with its execution.Treat behind the blood clotting from blood sample collection serum and in-20 ℃ of storages.Use enzyme-linked immunosorbent assay (ELISA) to analyze the level of anti-PGA serum antibody and anti-DNI serum antibody.In brief, by volume the 0.1M sodium carbonate buffer (pH9.6) that contains 0.5 μ g/ hole BSA-PGA or DNI in 100 μ L/ holes to Immulon 2HB ELISA (VWR) microtitration plate bag.After 4 ℃ of incubated overnight, by with 3%BSA (w/v) (being dissolved in TBS-0.1% tween (TBST)) in room temperature 1 hour or 4 ℃ of night incubation, seal and be coated with antigenic plate.The blood serum sample that will merge from four mice groups when the time point behind each booster immunization carries out serial dilution with TBST, it is joined be coated with in the antigenic plate, hatches at least 1 hour.Use at Mus IgG that puts together with alkali phosphatase (Zymed) or the rabbit anti-serum of IgM, measure anti-DNI antibody response and anti-PGA antibody response.Be added to substrate p-nitrophenyl phosphate (PNPP) in each hole and measure the absorptance of each reaction in the 405nm place with spectrophotography.The form report that data are tired reciprocal with terminal point, the latter is defined as the OD of acquisition 405Reading surpass two standard deviations of negative control reading greatest dilution.
Measure in intravital IgM of mice and special anti-DNI and the anti-PGA immunne response of IgG with the ELISA algoscopy through three kinds of PCMV preparation 1-3 and two antigen control preparations 4 and 5 (Fig. 3-5) immunity inoculation.As shown in Figure 3, except the control formulation 4 without glutaraldehyde cross-linking (no glutaraldehyde), the DNI albumen in all preparations has hyperimmunization originality.Yet these DNI specific immune responses are only based on IgG's.Though even also detect less than anti-DNI IgM the 7th day of immunity inoculation, at the 17th day, in the mice body of crossing through the mice and crosslinked DNI (preparation 5) immunity inoculation of those usefulness of PCMV preparation immunity inoculation, can detect significant anti-DNI IgG and reply.Observed after inoculation comprises all preparations of preparation 4 strong booster response at DNI at the 30th day.
Anti-PGA IgM replys and has shown typical pod membrane polymer pattern (Fig. 4).Control formulation 4 produced detectable anti-PGA IgM at the 7th day and replys, but the 17th or 30 day this do not reply and be reinforced.All PCMV preparations induced anti-PGA IgM to reply at the 7th day, produced exclusive then the 17th day and the 30th day even stronger anti-PGA IgM replys.As expected, control formulation 5 (having only crosslinked DNI) does not produce based on IgM or based on the anti-PGA of IgG and replys.What form sharp contrast is, PCMV1-3 (preparation 1-3) produces intensive anti-PGA based on IgG and replys, and this is replied performance in the 7th day obviously subsequently at the 30th day significantly strengthened (Fig. 5).Finding is similar at replying obviously based on the anti-PGA of IgG of PCMV1-3: the observed conventional P GA-DNI conjugate vaccines of Aulinger etc. report inductive immunne response (Infect.Immun.73:3408-3414 to PGA, 2005) and Rhie etc.) inductive the replying of PA-PGA conjugate vaccines (Proc.Natl.Acad.Sci.USA100:10925-10930,2003 described.Therefore inducing (Bacillus anthracis (B.anthracis) protection antigen (Wang etc. of known T cell dependent/non-dependent at pod membrane PGA; Infect.Immun.72:5460-5463; 2004) IgG) replys the aspect, and PCMV vaccine #1, #2 have and traditional the same good performance of PGA vaccine of puting together with #3.Contain with the control formulation 5 of the blended DNI of PGA (noncrosslinking) and do not induce detectable IgG, show DNI does not serve as the TLR part in the anti-PGA of IgG that stimulates PCMV preparation 1-3 replys effect at PGA.This result has also confirmed the observation in the document, and promptly PGA is the T cell dependent/non-dependent immunogen of reduced immunogenicity, unless it is by covalently bound and protein coupling (Rhie etc., Proc.Natl.Acad.Sci.USA 100:10925-10930,2003).The PCMV method obviously changes into PGA the dependent immunogen of T cell, although in fact this method do not cause DNI albumen directly and the PGA molecule carry out crosslinked.
These data support the PCMV method can prepare characteristic and the similar immunogen of traditional conjugate vaccines.Prepare PGA PCMV easily with method as herein described, and find the typical immunne response that it induces PGA-albumen conjugate vaccines.The small-scale prepared in reaction that describes in detail in the table 1 goes out the dosage of describing based on Fig. 3 enough carries out immunity inoculation to 1000 mices PCMV.These data are supported can be used as the anthrax that vaccine prevention is caused by Bacillus anthracis (Bacillus anthracis) by the PCMV of PGA and DNI preparation.
Preparation and the sign of embodiment 3. additional PCMV
The PCMV technology can be applicable to the k antigen of various structures and ionic charge.23 types of streptococcus pneumoniae (Streptococcus pneumonia) PS is available from American type culture collection (ATCC) and by Merck, and Inc makes.These PS are very different on its molecular structure, comprise the reinforcing YIN-essence ion-type, the PS partial cation type, neutral charge, phosphorylation, linear, that branched structure is arranged and that modify through various alternate manners.In preliminary experiment, get these PS subclass corresponding to 7 pod membrane types among the Wyeth product P revnar (4,6B, 9V, 14,18C, 19F and 23F), measure the ability that its inducing mouse macrophage produces IL-6.The PS of 4 types enlivens in mensuration; Lipopolysaccharide (LPS) is the contrast of TLR agonist.Also measured other PS (for example, 3 types), PGA and draw O antigen PS of hot Frances Salmonella (F.tularensis) and the PCMV vaccine that is prepared from by PGA-DNI and do not have crosslinked contrast from soil.This experiment has shown that 3 type streptococcus pneumoniae PS (degree than PGA is less) also are subjected to the TLR agonist and pollute.Draw the PS of hot Frances Salmonella (F.tularensis) and PCMV equal clean in mensuration from soil.Phenol extraction and ethanol precipitation can be after twice be handled continuously " cleaning " (removing the unknown TLR agonist of remnants) streptococcus pneumoniae (S.pneumoniae) PS 3 types.Therefore, find that 6 kinds of streptococcus pneumoniae (S.pneumoniae) PS and soil draw hot Frances Salmonella (F.tularensis) O antigen PS to clean totally for the generation of IL6, these are probed in experiment as herein described.
Utilize DNI as carrier protein by the method that is similar to described in the embodiment 1, cleaned 7 kinds of clean PS and carried out PCMV and synthesize producing for IL6.Preliminary immunogenicity determining shows that all seven kinds of PCMV have immunogenicity in various degree." unit price " PCMV (14-PCMV) based on DNI that finds streptococcus pneumoniae (S.pneumoniae) PS14 induces the remarkable enhanced height anti-PPS14 IgG that tires after immunity for the third time.Obviously, when six kinds of PCMV of 14-PCMV and other mix generation " mixing " antigen, can see same immunne response.Because

Be " adjuvantization " vaccine of absorption Alumen, so whether also can be determined by adsorbed onto alum adjuvant absorption to sexavalence PCMV mixture.Come observation measurements being exposed to the amount that PCMV or control mixture (identical PS mixes with DNI albumen but do not carry out glutaraldehyde cross-linking) are adsorbed in the streptococcus pneumoniae PS of Alumen afterwards by immunoassay, the result shows, the PS comparison that is adsorbed in Alumen under the PCMV background is according to (the noncrosslinking DNI albumen of PS+) much more (this as further the immunoreactivity higher level of the PCMV of dilution is indicated in immunoassay).
Mice is carried out immunity, the immunogenicity of the septivalency PCMV of the adsorbed onto alum adjuvant of being adsorbed in is arranged or do not have with evaluation.Adsorbed onto alum adjuvant is improved the immunne response kinetics to PS14, takes Zao 7 days with induce the IgG at this PS than no Adjuvanted vaccines.Yet, have more immunogenicity than the non-crosslinked PS+DNI combination contrast that has Alumen at the septivalency PCMV that does not have Alumen.This result has confirmed that the PCMV method makes PS have more immunogenicity for mice, and has supported the PCMV method can be used for preparing the antigen mixture that immune performance is similar to the conjugate vaccines mixture.
In other experiment, use phenol extraction and ethanol precipitation so that contaminative TLR agonist is removed from 23 kinds of pneumococal polysaccharide commercial formulation.Method with standard is come to testing through treated PS, to confirm the removal situation of pollutant according to inducing peritoneal macrophages to produce IL-6.The PS that lacks the IL-6 induced activity is used to prepare PCMV.Other polysaccharide that is used for PCMV comprises from soil and draws the O antigen PS of hot Frances Salmonella (F.tularensis) purification and from the PGA pod membrane of Bacillus anthracis (B.anthracis).25 pod membrane types (23 streptococcus pneumoniae types, each one of tularemia type and anthrax pattern of fever) have altogether been checked.Each of 25 kinds of pod membrane types is passed through embodiment 1 described method substantially, prepares PCMV with DNI albumen.PS with 1: 1 ratio: albumen is used for (about 1: 1 dry weight) these initial p CMV preparation.By SDS-PAGE every kind of preparation is characterized, confirming proteic crosslinked situation, the immunogenicity of various PCMV preparations is relevant fully in protein-crosslinking situation and the preliminary experiment.For some pod membrane type (for example 6B and 23F), use other carrier protein to prepare PCMV.For these same pod membrane types (for example 6B and 23F), can use alternative cross-linking chemistry.Immunogenicity to all PCMV preparations of having confirmed protein-crosslinking (for example in SDS-PAGE) is tested.
For example, below with 10 kinds of different PCMV of 5 kinds of different stromatins and 2 kinds of different antigen preparation.The selection of 5 kinds of stromatins based on: their are current to be used for vaccine of FDA approval, perhaps allows it to be used to measure other characteristic of PCMV preparation stability as tracer.Used following stromatin: (1) b subunit of cholera toxin (SBL Vaccin AB provides), (2) diphtheria toxin, diphtherotoxin, (3) tetanus toxin fragment C, " Frag C " (Sigma Aldrich provides), (4) DNI and (5) are from the beta galactosidase (SigmaAldrich provides) of escherichia coli (Escherichia coli).As k antigen, used k antigen to gather-D-glutamic acid and 14 type streptococcus pneumoniae (Streptococcuspneumoniae) pod membrane (Suarez etc. from Bacillus anthracis (Bacillusanthracis), Appl.Environ.Micobiol.67:969-971,2001).When being used for corresponding PCMV with DNI as stromatin, these two kinds of k antigens all have hyperimmunization originality.10 kinds of different PCMV are made in every kind of k antigen and 5 kinds of each combinations in the stromatin of selection.
As viewed in traditional conjugate vaccines, in the mice body, can test PCMV and induce isotype antibody to convert the ability of IgG to.Can make all antigens be adsorbed in the group that Alumen typically uses corresponding 5 mices of every kind of PCMV preparation then.Obtain at being tried antigenic immunne response baseline in advance the mice blood-letting.Peritoneal injection scheme by standard is to three immunity of mice several (in the 0th, 7,14 days) then, and the 10th, 20,30 and 60 day collection blood in initial immunity after.By the ELISA assay method of standard, mice serum is analyzed according to situation at the IgG of used PS and carrier protein.In these experiments, the control group mice of only accepting the PS immunity inoculation is included, be used for estimating various PCMV preparations with should non-immunogenicity or the low non-PS of puting together of immunogenicity compare the ability of inducing anti-PS IgG.Make promising PCMV (promptly inducing high-level anti-PS IgG) through careful immune analysis, manage to set up kinetics and the dose response situation of mice the PCMV immunne response.
Perhaps, promising PCMV and its corresponding contrast can be delivered to businessman to produce rabbit anti-serum.Carry out similar immunoassay estimate immunogenicity, the classification, the immunne response kinetics of rabbit of inductive antibody.In these experiments, contrast is the commercially available prod
