The result showed that either of H58N35-33T1 VLP and H58N35-33T5 VLP could induce the generation of high-titer neutralizing antibodies against HPV33 and HPV58 in mice; and their protective effects against HPV58 were comparable to that of HPV58N35 VLP alone, and were significantly higher than that of HPV33N9 VLP alone; and their protective effects against HPV33 were comparable to that of HPV33N9 VLP alone, and were significantly higher than that of HPV58N35 VLP alone. This showed that H58N35-33T1 VLP and H58N35-33T5 VLP could be used as effective vaccines for preventing HPV58 infection and HPV33 infection, and could be used in place of a mixed vaccine comprising HPV58 VLP and HPV33 VLP.

The result showed that either of 1158N35-33T1-52S1 VLP and H58N35-33T1-52S4 VLP could induce the generation of high-titer neutralizing antibodies against HPV58, HPV33 and HPV52 in mice; and their protective effects against HPV58 was comparable to that of HPV58N35 VLP alone and that of the mixed HPV58/HPV33/HPV52 VLP, and were significantly higher than that of HPV33N9 VLP alone and that of HPV52N40 VLP alone; and their protective effects against HPV33 were comparable to that of HPV33N9 VLP alone and that of the mixed HPV58/HPV33/HPV52 VLP, and were significantly higher than that of HPV58N35 VLP alone and that of HPV52N40 VLP alone; and their protective effects against HPV52 were comparable to that of HPV52N40 VLP alone and that of the mixed HPV58/HPV33/HPV52 VLP, and were significantly higher than that of HPV33N9 VLP alone and that of HPV58N35 VLP alone. This showed that H58N35-33T1-52S1 VLP and H58N35-33T1-52S4 VLP could be used as effective vaccines for preventing HPV58 infection, HPV33 infection and HPV52 infection, and could be used in place of a mixed vaccine comprising HPV58 VLP, HPV33 VLP and HPV52 VLP.

This showed that H58N35-33T1-52S4 VLP had good cross-immunogenicity against HPV58, HPV33 and HPV52, and could induce good cross-protection against HPV58, HPV33 and HPV52 in primate.

    [0082] FIGS. 10A-10D show the cryo-electron microscopy (cryoEM) photographs and the reconstructed three-dimensional structures of H58N35-33T1 VLP and H58N35-33T1-52S4 VLP, respectively. FIG. 10A, the cryo-electron microscopy (cryoEM) photograph of H58N35-33T1 VLP; FIG. 10B, the reconstructed three-dimensional structure of H58N35-33T1 VLP; FIG. 10C, the cryo-electron microscopy (cryoEM) photograph of H58N35-33T1-52S4 VLP; FIG. 10D, the reconstructed three-dimensional structure of H58N35-33T1-52S4 VLP. The reconstructed three-dimensional structures showed that both H58N35-33T1 VLP and H58N35-33T1-52S4 VLP had a T=7 icosahedral structure (h=1, k=2) consisting of 72 capsomers (morphological subunit, pentamer). Unlike conventional icosahedral viral capsids consistent with quasi-equivalence principle, all the constitutive subunits in the structures of H58N35-33T1 VLP and H58N35-33T1-52S4 VLP were pentamers, without hexamer. Moreover, said two VLPs had an external diameter of about 60 nm. These were similar to the three-dimensional structures of the previously reported natural HPV viral particles and the HPV VLP prepared by eukaryotic expression system (e.g. poxvirus expression system) (Baker T S, Newcomb W W, Olson N H. et al. Biophys J. (1991), 60(6): 1445-1456. Hagensee M E, Olson N H, Baker T S, et al. J Virol. (1994), 68(7):4503-4505. Buck C B, Cheng N, Thompson C D. et al. J Virol. (2008), 82(11): 5190-7).

    EXAMPLE 1. EXPRESSION AND PURIFICATION OF THE MUTATED HPV58 L1 PROTEINS

    Construction of Expression Vectors

    [0086] An expression vector encoding the mutated HPV58 L1 protein comprising a segment from HPV33 L1 protein was constructed by PCR for multi-site mutagenesis, wherein the initial template used was the plasmid pTO-T7-HPV58L1N35C (encoding the HPV58 L1 protein having 35 amino acids truncated at N-terminal; abbreviated as 58L1N35 in Table 2). The templates and primers for each PCR were shown in Table 2, and the amplification conditions for PCR were as followed: denaturation at 94 C. for 10 min; 25 cycles (denaturation at 94 C. for 50 sec, annealing at a given temperature for a certain period of time, and extension at 72 C. for 7.5 min); and final extension at 72 C. for 10 min. The sequences of the PCR primers used were listed in Table 3.

    [0087] To the amplification product (50 L), 2 L restriction endonuclease DpnI was added, and the resultant mixture was incubated at 37 C. for 60 min. 10 L of the product of digestion was used to transform 40 L competent E. coli ER2566 (purchased from New England Biolabs) prepared by the Calcium chloride method. The transformed E. coli was spread onto solid LB medium (the components of the LB medium: 10 g/L peptone, 5 g/L yeast powder, 10 g/L NaCl, the same hereinafter) containing kanamycin (at a final concentration of 25 mg/mL, the same hereinafter), and was subjected to static culture at 37 C. for 10-12 h until single colonies could be observed clearly. Single colony was picked and inoculated into a tube containing 4 mL liquid LB medium (containing kanamycin), and cultured with shaking at 220 rpm for 10 h at 37 C., and then 1 ml bacterial solution was taken and stored at 70 C. Plasmids were extracted from E. coli, and T7 primer was used to sequence the nucleotide sequences of the fragments of interest inserted into the plasmids. The sequencing result showed that the nucleotide sequences of the fragments of interest inserted into the constructed plasmids (expression vectors) were SEQ ID NO: 18, 19, 20, 21, 22, 23, and 24, respectively, and their encoded amino acid sequences were SEQ ID NO: 4, 5, 6, 7, 8, 9, and 10, respectively (the corresponding proteins were designated as H58N35-33T1, H58N35-33T2-1, H58N35-3312-2, H58N35-33T2, H58N35-33T3, H58N35-33T4 and H58N35-33T5, respectively).

    [0088] The mutated protein H58N35-33T1 differs from HPV58N35 by: the substitution of the amino acid residues from positions 80 to 87 of wild type HPV58 L1 protein with the amino acid residues from positions 54 to 61 of wild type HPV33 L1 protein. The mutated protein H58N35-33T2 differs from HPV58N35 by: the substitution of the amino acid residues from positions 144 to 168 of wild type HPV58 L1 protein with the amino acid residues from positions 118 to 142 of wild type HPV33 L1 protein. The mutated protein H58N35-33T3 differs from HPV58N35 by: the substitution of the amino acid residues from positions 203 to 209 of wild type HPV58 L1 protein with the amino acid residues from positions 177 to 183 of wild type HPV33 L1 protein. The mutated protein H58N35-33T4 differs from HPV58N35 by: the substitution of the amino acid residues from positions 308 to 311 of wild type HPV58 L1 protein with the amino acid residues from positions 282 to 285 of wild type HPV33 L1 protein. The mutated protein H58N35-33T5 differs from HPV58N35 by: the substitution of the amino acid residues from positions 376 to 383 of wild type HPV58 L1 protein with the amino acid residues from positions 350 to 357 of wild type HPV33 L1 protein.

    [0089] Gibson assembly (Gibson D G, Young L, Chuang R Y, Venter J C, Hutchison C A, Smith H O. Enzymatic assembly of DNA molecules up to several hundred kilobases. Nat Methods. 2009;6:343-5. doi: 10.1038/ntneth.1318) was used to construct the expression vector encoding the mutated HPV58 L1 protein having double substitutions, wherein the mutated HPV58 L1 protein comprised a segment from HPV33 L1 and a segment from HPV52L1. In brief, a short fragment comprising mutations and a long fragment comprising no mutation were obtained by PCR, and Gibson assembly system was then used to ligate the two fragments to form a ring. The initial template used comprised the plasmid pTO-T7-H58N35-33T1 (encoding the mutated protein H58N35-33T1; abbreviated as H58N35-33T1 in Table 2) and the plasmid pTO-T7-HPV52N40C (encoding the HPV52 L1 protein having 40 amino acids truncated at N-terminal; abbreviated as 52L1N40 in Table 2). The templates and primers for each PCR were shown in Table 2, and, the amplification conditions for PCR for amplifying the short fragment were as followed: denaturation at 94 C. for 10 min; 25 cycles (denaturation at 94 C. for 50 sec, annealing at a given temperature for a certain period of time, and extension at 72 C. for 1 min); and final extension at 72 C. for 10 min. The amplification conditions for PCR for amplifying the long fragment were as followed: denaturation at 94 C. for 10 min; 25 cycles (denaturation at 94 C. for 50 sec, annealing at a given temperature for a certain period of time, and extension at 72 C. for 7.5 min); and final extension at 72 C. for 10 min. The sequences of the PCR primers used were listed in Table 3. The amplification product was subjected to electrophoresis, the fragment of interest was then recovered by using DNA Extraction Kit, and its concentration was determined. The short fragment and long fragment obtained by amplification were mixed at a molar ratio of 2:1 (a total volume of 3 L), and 34 of 2 X Gibson Assembly Master Mix (purchased from NEB, containing 15 exonuclease, Phusion DNA polymerase, Taq DNA ligase) was then added, and reacted at 50 C. for 1 h.

    [0090] The assembled product (64) was used to transform 40 .sub.1AL competent E. coli ER2566 (purchased from New England Biolabs) prepared by the Calcium chloride method. The transformed E. coli were spread onto solid LB medium containing kanamycin, and were subjected to static culture at 37 C. for 10-12 h until single colonies could be observed clearly. Single colony was picked and inoculated into a tube containing 4 mL liquid LB medium (containing kanamycin), and cultured with shaking at 220 rpm for 10 h at 37 C., and then 1 ml bacterial solution was taken and stored at 70 C. Plasmids were extracted from E. coli, and T7 primer was used to sequence the nucleotide sequences of the fragments of interest inserted into the plasmids. The sequencing result showed that the nucleotide sequences of the fragments of interest inserted into the constructed plasmids (expression vectors) were SEQ ID NO: 25, 26, 27, and 28, respectively, and their encoded amino acid sequences were SEQ ID NO: 11, 12, 13, and 14, respectively (the corresponding proteins were designated as H58N35-33T1-52S1, H58N35-33T1-52S2, 1-158N35-33T1-52S3, and H58N35-33T1-52S4, respectively).

    [0091] The mutated protein H58N35-33T1-52S1 differs from HPV58N35 by: the substitution of the amino acid residues from positions 80 to 87 of wild type HPV58 L1 protein with the amino acid residues from positions 54 to 61 of wild type HPV33 L1 protein, and the substitution of the amino acid residues from positions 144 to 168 of wild type HPV58 L1 protein with the amino acid residues from positions 146 to 170 of wild type HPV52 L1 protein. The mutated protein H58N35-33T1-52S2 differs from HPV58N35 by: the substitution of the amino acid residues from positions 80 to 87 of wild type HPV58 L1 protein with the amino acid residues from positions 54 to 61 of wild type HPV33 L1 protein, and the substitution of the amino acid residues from positions 200 to 209 of wild type HPV58 L1 protein with the amino acid residues from positions 202 to 212 of wild type HPV52 L1 protein.

Then, the culture was transferred to 500 mL LB medium containing kanamycin (1 ml bacterial solution was transferred), and was further incubated. When the bacterial concentration reached an OD.sub.600 of about 0.6, the culturing temperature was lowered to 25 C. and 500 L IPTG was added to each culture bottle. The incubation was further performed for 8 h. After the incubation was finished, the bacteria were collected by centrifugation. The bacteria expressing H58N35-33T1, H58N35-33T2, H58N35-33T3, H58N35-33T4, H58N35-33T5, H58N35-33T1-52S1, H58N35-33T1-52S2, H58N35-33T1-52S3, and H58N35-33T1-52S4 protein, were obtained, respectively.

    [0093] The bacteria obtained were re-suspended at a ratio of 1 g bacteria to 10 mL lysis buffer (20 mM Tris buffer, pH7.2, 300 mM NaCl). The bacteria were disrupted by using an ultrasonic apparatus for 30 min. The lysis solution containing the disrupted bacteria were centrifuged at 13500 rpm (30000 g) for 15 min, and the supernatant (i.e. the supernatant of disrupted bacteria) was obtained.

    Elution Protocol

    [0098] (1) Cation exchange purification of the supernatant of disrupted bacteria by SP Sepharose 4 Fast Flow: the sample was loaded on the column, undesired proteins were then eluted with a buffer containing 400 mM NaCl, followed by the elution of the protein of interest with a buffer containing 800 mM NaCl, and the fraction eluted with the buffer containing 800 mM NaCl was collected;

    [0099] (2) Chromatographic purification of the elution fraction obtained in the step (1) by CHTII (hydroxyapatite chromatography): the elution fraction obtained in the step (1) was diluted so that the NaCl concentration was decreased to 0.5 M; the sample was loaded on the column, undesired proteins were then eluted with a buffer containing 500 mM NaCl, followed by the elution of the protein of interest with a buffer containing 1000 mM NaCl, and the fraction eluted with the buffer containing 1000 mM NaCl was collected;

    [0100] (3) Chromatographic purification of the elution fraction obtained in the step (2) by HIC (hydrophobic interaction chromatography): the sample was loaded on the column, undesired proteins were then eluted with a buffer containing 1000 mM NaCl, followed by the elution of the protein of interest with a buffer containing 200 mM NaCl, and the fraction eluted with the buffer containing 200 mM NaCl was collected.

    [0101] 150 L elution fraction obtained in the step (3) was added to 30 AL of 6Loading Buffer. The resultant solution was mixed homogeneously and incubated in 80 C. water bath for 10 mM. 10 l of the resultant sample was then subjected to 10% SDS-PAGE at 120V for 120 mM; and the electrophoretic bands were stained by Coomassie brilliant blue. The electrophoretic result was shown in FIG. 1. The result showed that after said purification steps, H58N35-33T1, H58N35-33T2, H58N35-33T3, H58N35-33T4, H58N35-33T5, H58N35-33T1-52S1, H58N35-33T1-52S2, H58N35-33T1-52S3, and H58N35-33T1-52S4 protein had a purity of above 95%.

    EXAMPLE 2: ASSEMBLY OF HPV VIRUS-LIKE PARTICLES AND MORPHOLOGICAL DETECTION OF PARTICLES

    Assembly of HPV Virus-Like Particles

    [0104] A given volume (about 2 ml) of the protein H58N35-33T1, H58N35-33T2, H58N35-33T3, H58N35-33T4, H58N35-33T5, H58N35-33T1-52S1, H58N35-33T1-52S2, H58N35-33T1-52S3, or H58N35-33T1-52S4, was dialyzed to (1) 2 L storage buffer (20 mM sodium phosphate buffer pH 6.5, 0.5 M NaCl); (2) 2 L renaturation buffer (50 mM sodium phosphate buffer pH 6.0, 2 mM CaCl.sub.2, 2 mM MgCl.sub.2, 0.5 M NaCl); and (3) 20 mM sodium phosphate buffer pH 7.0, 0.5 M NaCl, successively. The dialysis was performed in each of the three buffers for 12 h.

    [0105] By similar methods, the HPV58N35, HPV33N9 and HPV52N40 protein were assembled into HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP, respectively.

    Molecular Sieve Chromatographic Analysis

    [0106] The dialyzed sample was subjected to molecular sieve chromatographic analysis by 1120 Compact LC High Performance Liquid Chromatographic System (Agilent Technologies), wherein the analytical column used was TSK Gel PW5000xl 7.8300 mm. The analysis results were shown in FIGS. 3A-3L. The results showed that the first protein peak of the samples comprising the protein H58N35-33T1, H58N35-33T3, H58N35-33T4, H58N35-33T5, H58N35-33T1-52S1, H58N35-3311-5252, H58N35-33T1-52S3, and H58N35-33T1-52S4 appeared at about 12 min, which was comparable to that of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP. This showed that all these protein were able to assemble into VLPs. However, the first protein peak of the sample comprising the protein H58N35-33T2 appeared at about 16 min, which was comparable to the retention time of the pentamer of HPV58 L1 protein, indicating that the protein was unable to assemble into VLP.

    Sedimentation Velocity Analysis

    [0107] The apparatus for sedimentation velocity analysis was Beckman XL-A Analytical Ultracentrifuge, equipped with optical inspection system and An-50Ti and An-60Ti rotor. The sedimentation coefficient of H58N35 VLP, HPV33N9 VLP and H58N35-33T1 VLP was analyzed by sedimentation velocity method. The results were shown in FIGS. 4A-4F. The results showed that the sedimentation coefficient of H58N35-33T1 VLP, H58N35-33T1-52S1 VLP and H58N35-33T1-52S4 VLP was 109S, 113S and 109S, respectively, while the sedimentation coefficient of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP was 118S, 133S and 131S, respectively. This showed that H58N35-33T1, H58N35-33T1-52S1 and H58N35-33T1-52S4 were able to assemble into virus-like particles that were similar to wild type VLP in terms of size and morphology.

    Morphological test of virus-like particles

    [0108] A 100 L sample comprising VLP was observed by transmission electron microscope (TEM). The equipment used was a 100 kV Transmission Electron Microscope supplied by JEOL Ltd. (100,000 magnification). In brief, a 13.5 L sample was negatively stained with 2% phosphotungstic acid (pH 7.0), fixed on a carbon-coated copper grid, and then observed by TEM. The results were shown in FIGS. 5A-5L. The results showed that H58N35-33T1, H58N35-33T3, H58N35-33T4, H58N35-33T5, H58N35-33T1-52S1, H58N35-33T1-52S2, H58N35-33T1-52S3, and H58N35-33T1-52S4 were able to assemble into virus-like particles. In addition, the results also showed that the particles assembled by these mutated proteins had a radius of about 30 nm, and were uniform in size. This indicated that these mutated proteins were similar to the L1 protein of HPV33, HPV58 and HPV52, and were able to assemble into VLPs with a uniform size. H58N35-33T2 could only form pentamer, but was unable to assemble into virus-like particle.

    EXAMPLE 3: EVALUATION OF THERMOSTABILITY OF VIRUS-LIKE PARTICLES

    [0109] The VLPs formed by H58N35-33T1, H58N35-33T1-52S1, H58N35-33T1-52S2, H58N35-33T1-52S3, and H58N35-33T1-52S4 were evaluated for their thermostability by using a differential scanning calorimeter VP Capillary DSC purchased from GE Company (i.e. the MicroCal Co.), wherein the storage buffer for the protein was used as control, and the proteins were scanned at a heating rate of 1.5 C./min within a temperature range of 10 C.-90 C. The detection results were shown in FIGS. 6A-6F. The results showed that all these VLPs formed by the proteins had very high thermostability.

    EXAMPLE 4: EVALUATION 1 OF IMMUNE PROTECTION OF VIRUS-LIKE PARTICLES IN ANIMALS

    [0110] The immune protection of the VLPs formed by H58N35-33T1, H58N35-33T3, H58N35-33T4, H58N35-33T5, H58N35-3311-5251, H58N35-33T1-52S2, H58N35-33T1-52S3, and H58N35-33T1-52S4, was evaluated in mice. Animals for vaccination were BALB/c mice (ordinary grade), 5-6 weeks old (purchased from Shanghai SLAC Laboratory Animal Co. LTD.).

    [0111] The H58N35-33T1 VLP, H58N35-33T3 VLP, H58N35-33T4 VLP, H58N35-33T5 VLP, HPV58N35 VLP and HPV33N9 VLP as prepared above were absorbed onto Freund's adjuvant, respectively. Mice were divided into 6 groups depending on immunogen, and each group included 3 mice. Vaccination procedure was as followed: the first vaccination at Week 0, and the booster vaccination at Weeks 2 and 4, respectively. Mice were vaccinated via subcutaneous injection. The immunogens used and doses thereof were shown in Table 4. At Week 8 after the first vaccination, venous blood was collected from eyeball, and serum was separated. The titers of neutralizing antibodies in the serum were determined. The detection result was shown in FIG. 7A. The result showed that either of H58N35-33T1 VLP and H58N35-33T5 VLP could induce the generation of high-titer neutralizing antibodies against HPV33 and HPV58 in mice; and their protective effects against HPV58 were comparable to that of HPV58N35 VLP alone, and were significantly higher than that of HPV33N9 VLP alone; and their protective effects against HPV33 were comparable to that of HPV33N9 VLP alone, and were significantly higher than that of HPV58N35 VLP alone. This showed that H58N35-33T1 VLP and H58N35-33T5 VLP could be used as effective vaccines for preventing HPV58 infection and HPV33 infection, and could be used in place of a mixed vaccine comprising HPV58 VLP and HPV33 VLP.

    [0112] In addition, the H58N35-33T1-52S1 VLP, H58N35-33T1-52S2 VLP, H58N35-33T1-52S3 VLP, H58N35-33T1-52S4 VLP, HPV58N35 VLP, HPV33N9 VLP, HPV52N40 VLP and a mixed HPV58/HPV33/HPV52 VLP (i.e. a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP) as prepared above were absorbed onto aluminum adjuvant. Mice were divided into 8 groups depending on immunogen, and each group included 4 mice. Vaccination procedure was as followed: the first vaccination at Week 0, and the booster vaccination at Weeks 2 and 4, respectively. Mice were vaccinated via intraperitoneal injection. The immunogens and doses thereof were shown in Table 5. At Week 8 after the first vaccination, venous blood was collected from eyeball, and serum was separated. The titers of neutralizing antibodies in the serum were determined. The detection result was shown in FIG. 7B. The result showed that either of H58N35-33T1-52S1 VLP and H58N35-33T1-52S4 VLP could induce the generation of high-titer neutralizing antibodies against HPV58, HPV33 and HPV52 in mice; and their protective effects against HPV58 was comparable to that of HPV58N35 VLP alone and that of the mixed HPV58/HPV33/HPV52 VLP, and were significantly higher than that of HPV33N9 VLP alone and that of HPV52N40 VLP alone; and their protective effects against HPV33 were comparable to that of HPV33N9 VLP alone and that of the mixed HPV58/HPV33/HPV52 VLP, and were significantly higher than that of HPV58N35 VLP alone and that of HPV52N40 VLP alone; and their protective effects against HPV52 were comparable to that of HPV52N40 VLP alone and that of the mixed HPV58/HPV33/HPV52 VLP, and were significantly higher than that of HPV33N9 VLP alone and that of HPV58N35 VLP alone. This showed that H58N35-33T1-52S1 VLP and H58N35-33T1-52S4 VLP could be used as effective vaccines for preventing HPV58 infection, HPV33 infection and HPV52 infection, and could be used in place of a mixed vaccine comprising HPV58 VLP, HPV33 VLP and HPV52 VLP.

    ED.SUB.50 .of H58N35-33T1 VLP

    [0113] 6-week old BalB/c female mice (8 mice) were vaccinated with aluminum adjuvant by single intraperitoneal injection, wherein H58N35-33T1 VLP was used in the Experimental groups, and HPV58N35 VLP alone or HPV33N9 VLP alone was used in the Control groups; the immunizing dose was 0.300 g, 0.100 g, 0.033 g, 0.011 g or 0.004 g; the immunizing volume was 1 mL. At Week 5 after vaccination, venous blood was collected from eyeball. Antibodies against HPV in the blood were detected, and by Reed-Muench method (Reed LJ MH.

    [0116] The results showed that 5 weeks after vaccination of mice, ED.sub.50 of H58N35-33T1-52S1 VLP and H58N35-33T1-52S4 VLP for inducing the generation of antibodies against HPV58 in mice was comparable to that of HPV58N35 VLP alone and of a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP, and was significantly superior to that of HPV33N9 VLP alone and HPV52N40 VLP alone; and their ED.sub.50 for inducing the generation of antibodies against HPV33 in mice was comparable to that of HPV33N9 VLP alone and of a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP, and was significantly superior to that of HPV58N35 VLP alone and of HPV52N40 VLP alone; and their ED.sub.50 for inducing the generation of antibodies against HPV52 in mice was comparable to that of HPV52N40 VLP alone and of a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP, and was significantly superior to that of HPV33N9 VLP alone and of HPV58N35 VLP alone. This showed that H33N9-58T5-52S2 VLP and H33N9-58T5-52S4 VLP had good cross-immunogenicity and cross-protection against HPV58, HPV33 and HPV52.

    Evaluation of Neutralizing Antibody Titer in Serum of Mice Vaccinated with H58N35-33T1 VLP

    [0117] In this experiment, vaccination schedule was shown in Table 15. All the mice (6-week old BalB/c female mice) were divided into 4 groups: Freund's adjuvant group (at an immunizing dose of 1 g, using Freund's adjuvant), Aluminum adjuvant group 1 (at an immunizing dose of 10 g, using aluminum adjuvant), Aluminum adjuvant group 2 (at an immunizing dose of 1 g, using aluminum adjuvant), and Aluminum adjuvant group 3 (at an immunizing dose of 0.1 g, using aluminum adjuvant). Each group was further divided into 3 subgroups. The Control subgroups 1 and 2 were vaccinated with HPV33N9 VLP alone and HPV58N35 VLP alone, respectively, and the Experimental subgroup was vaccinated with H58N35-33T1 VLP.

    [0118] In Freund's adjuvant group, 6 mice/subgroup were vaccinated by subcutaneous injection, at an immunizing dose of 1 g, and an injection volume of 200 l. In Aluminum adjuvant groups 1-3, 6 mice/subgroup were vaccinated by intraperitoneal injection, at an immunizing dose 10 g, 1 g, and 0.1 g, respectively, and an injection volume of 1 mL. All the mice were subjected to the first vaccination at Week 0, and then subjected to the booster vaccination at Weeks 2 and 4, respectively. At Week 8, blood sample was collected via orbital bleeding, and the titers of antibodies against HPV58 and HPV33 in serum were analyzed. The analysis results were shown in FIGS. 8A-8D. The results showed that H58N35-33T1 VLP could induce the generation of high-titer neutralizing antibodies against HPV58 in mice, and its protective effect was comparable to that of HPV58N35 VLP alone at the same dose, was significantly superior to that of HPV33N9 VLP alone at the same dose; and it could induce the generation of high-titer neutralizing antibodies against HPV33 in mice, and its protective effect was comparable to that of HPV33N9 VLP alone at the same dose, and was significantly superior to that of HPV58N35 VLP alone at the same dose. This showed that H58N35-33T1 VLP had good cross-immunogenicity and cross-protection against HPV58 and HPV33.

    [0119] In this experiment, vaccination schedule was shown in Table 16. All the mice (6-week old BalB/c female mice) were divided into 3 groups: Aluminum adjuvant group 1 (at an immunizing dose of 10 g, using aluminum adjuvant), Aluminum adjuvant group 2 (at an immunizing dose of 1 g, using aluminum adjuvant), and Aluminum adjuvant group 3 (at an immunizing dose of 0.1 g, using aluminum adjuvant). Each group was further divided into 6 subgroups. The Control subgroups 1, 2 and 3 were vaccinated with HPV58N35 VLP alone, HPV33N9 VLP alone and HPV52N40 VLP alone, respectively; the Control subgroup 4 was vaccinated with a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP; and the Experimental subgroups 1 and 2 were vaccinated with H58N35-33T1-52S1 VLP alone and H58N35-33T1-52S4 VLP alone, respectively.

    [0120] In Aluminum adjuvant groups 1-3, 6 mice/subgroup were vaccinated by intraperitoneal injection, at an immunizing dose of 10 g, 1 g, and 0.1 g, respectively, and an injection volume of 1 mL. All the mice were subjected to the first vaccination at Week 0, and then subjected to the booster vaccination at Weeks 2 and 4, respectively. At Week 8, blood sample was collected via orbital bleeding, and the titers of antibodies against HPV58, HPV33 and HPV52 in serum were analyzed. The analysis results were shown in FIGS. 8E-8G. The results showed that H58N35-33T1-52S1 VLP and H58N35-33T1-52S4 VLP could induce the generation of high-titer neutralizing antibodies against HPV58 in mice, and their protective effect was comparable to that of HPV58N35 VLP alone and that of a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP at the same dose, and was significantly superior to that of HPV33N9 VLP alone or HPV52N40 VLP alone at the same dose; and they could induce the generation of high-titer neutralizing antibodies against HPV33 in mice, and their protective effect was comparable to that of HPV33N9 VLP alone and that of a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP at the same dose, and was significantly superior to that of HPV58N35 VLP alone or HPV52N40 VLP alone at the same dose; and they could induce the generation of high-titer neutralizing antibodies against HPV52 in mice, and their protective effect was slightly weaker than that of HPV52N40 VLP alone and that of a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP at the same dose, but was significantly superior to that of HPV58N35 VLP alone or HPV33N9 VLP alone at the same dose. This showed that H58N35-33T1-52S1 VLP and H58N35-33T1-52S4 VLP had good cross-immunogenicity and cross-protection against HPV58, HPV33 and HPV52.

    EXAMPLE 6: EVALUATION OF IMMUNE PROTECTION OF H58N35-33T1-52S4 VLP IN CYNOMOLGUS MONKEY

    [0121] This experiment was carried out in the Yunnan Key Laboratory of Primate Biomedical Research. Vaccination schedule was shown in Table 17. 14 cynomolgus monkeys were randomly divided into two groups: the Control group was vaccinated with a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP, at a dose of 5 g for each VLP, and an injection volume of 1 mL; the Experimental group was vaccinated with H58N35-33T1-52S4 VLP alone, at a dose of 5 g, and an injection volume of 1 mL. The adjuvant used was aluminum adjuvant, and the cynomolgus monkeys were vaccinated by intramuscular injection. All the cynomolgus monkeys were subjected to the first vaccination at Week 0, and then subjected to the booster vaccination at Week 8. Blood was collected from cynomolgus monkeys at Week 10, and the titers of antibodies against HPV58, HPV33 and HPV52 in serum were analyzed. The analysis result was shown in FIG. 9. The result showed that H58N35-33T1-52S4 VLP alone could induce the generation of high-titer neutralizing antibodies against HPV58, HPV33 and HPV52 in cynomolgus monkeys, and its protective effect was comparable to that of a mixture of HPV58N35 VLP, HPV33N9 VLP and HPV52N40 VLP at the same dose. This showed that H58N35-33T1-52S4 VLP had good cross-immunogenicity against HPV58, HPV33 and HPV52, and could induce good cross-protection against HPV58, HPV33 and HPV52 in primates.

    EXAMPLE 7: RECONSTRUCTION OF THREE-DIMENSIONAL STRUCTURES OF H58N35-33T1 VLP AND H58N35-33T1-52S4 VLP

    [0122] The three-dimensional structures of H58N35-33T1 VLP and H58N35-33T1-52S4 VLP were reconstructed by three-dimensional structure reconstruction experiment using cryo-electron microscopy (cryoEM) (Wolf M, Garcea R L, Grigorieff N. et al. Proc Natl Acad Sci USA. (2010), 107(14): 6298-303). In brief, in the cryo-electron microscopy (cryoEM) photograph of H58N35-33T1 VLP (FIG. 10A), 581 particles with an uniform size and a diameter of greater than 50 nm were selected for computer overlapping and structural reconstruction, thereby obtaining the three-dimensional structure of H58N35-33T1 VLP. The three-dimensional structure obtained was shown in FIG. 10B (at a resolution of 22). In addition, in the cryo-electron microscopy (cryoEM) photograph of H58N35-33T1-5254 VLP (FIG. 10C), 220 particles with an uniform size and a diameter of greater than 50 nm were selected for computer overlapping and structural reconstruction, thereby obtaining the three-dimensional structure of H58N35-33T1-52S4 VLP. The three-dimensional structure obtained was shown in FIG. 10D (at a resolution of 18). The results showed that both H58N35-33T1 VLP and H58N35-33T1-52S4 VLP had a T=7 icosahedral structure (h=1, k=2) consisting of 72 capsomers (morphological subunit, pentamer). Unlike conventional icosahedral viral capsids consistent with quasi-equivalence principle, all the constitutive subunits in the structures of H58N35-33T1 VLP and H58N35-33T1-52S4 VLP were pentamers, without hexamer. Moreover, said two VLPs had an external diameter of about 60 nm. These were similar to the three-dimensional structures of the previously reported natural HPV viral particles and the HPV VLP prepared by eukaryotic expression system (e.g. poxvirus expression system) (Baker T S, Newcomb W W, Olson N H. et al. Biophys J. (1991), 60(6): 1445-1456. Hagensee M E, Olson N H, Baker T S, et al. J Virol. (1994), 68(7):4503-4505. Buck C B, Cheng N, Thompson C D. et al. J Virol. (2008), 82(11): 5190-7).
