FIELD OF THE INVENTION
The present invention relates to a method of preparing a novel recombinant adenovirus (RAdEs) vaccine to protect against Japanese encephalitis virus (JEV) infection. Also, it relates to a method of immunization and to the vaccine per se.
BACKGROUND AND PRIOR ART REFERENCES OF THE INVENTION
Japanese encephalitis virus (JEV) is a member of the flaviviridae family of animal viruses that consists of several viruses of immense medical significance such as those causing dengue and yellow fever. JEV, transmitted to human beings by mosquitoes, is responsible for an acute infection of the central nervous system resulting in encephalitis. The virus is active over a vast geographic area covering India, China, Japan and virtually all of the South-East Asia. Approximately 3 billion people live in JEV endemic area and up to 50,000 cases of JEV infection are reported every year, of which, about 10,000 cases result in fatality and a high proportion of survivors end up having serious neurological and psychiatric sequel (45). A mouse brain-grown, formalin-inactivated JEV vaccine is available internationally. However, this vaccine has limitations in terms of its high cost of production, lack of long-term immunity and risk of allergic reaction due to the presence of the murine encephalogenic basic proteins or gelatin stabilizer (1, 33, 38, 39). There is, thus, an urgent need to develop an improved vaccine against JEV and several potential vaccines are currently being investigated in various laboratories (16).
JEV contains a single-stranded, plus-sense RNA genome of ˜11 Kb. It consists of a single open reading frame that codes for a large polyprotein of 3432 amino acids which is co- and post-translationally cleaved into three structural (capsid, C; pre-membrane, prM; and envelope, E) and seven non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B and NS5) (5, 44). In flaviviruses, E protein is involved in a number of important functions related to virus infection such as receptor binding and membrane fusion (26). Antibodies to the E protein were shown to neutralize virus activity in vitro as well as in vivo since passive administration of monoclonal antibodies to the E protein protected mice with JEV infection (17). Furthermore, sub-viral particles consisting of only the prM and the E proteins were highly effective in generating protective immune response in mice against JEV (18, 25). Chen et al. (7) examined the potential of various JEV structural and non-structural proteins for vaccine development. They concluded that the E protein was the single most important protein capable of inducing protective immunity against JEV. Accordingly, several plasmid vectors have been described synthesizing different forms of JEV E protein with or without prM protein and these provided protection of varying degree in mice against Japanese encephalitis (2, 6, 15, 20).
In recent years, adenoviruses have shown great promise as vectors for recombinant vaccine development (3, 4, 8, 13, 35, 41, 42, 49). Besides being safe, these viruses have been shown to induce effective humoral and cellular immune responses in experimental animals when delivered orally, intra-muscular (IM), intra-peritoneal or intra-nasal (3, 21, 24, 40, 41, 50). In the present invention, we constructed RAdEa expressing the prM and the full length JEV E protein since it is known to induce neutralizing immune response. However, adenovirus recombinant (RAdEa) synthesizing the full-length protein (Ea) did not grow well. Besides it induced poor immune response and very little JEV neutralizing antibodies. The full-length E protein is membrane anchored and removing the anchor signal from it is likely to make it soluble and perhaps more immunogenic.
On this premise, we truncated the Ea protein to remove 102-amino acid hydrophobic sequence from the C-terminus of the protein to generate a 398-amino acid Es protein. Recombinant adenovirus RAdEs synthesizing JEV prM and Es was found to grow very well in cultured cells and synthesize JEV E protein that was secreted into the medium. So, the removal of 102-amino acid hydrophobic sequence from the C-terminus of the protein played a critical role in smooth culturing of the recombinant. Even the inventors were pleasantly surprised with this effect.
Further, this recombinant adenovirus, synthesizing a novel form of JEV E protein that was secretory as opposed to the anchored protein in the normal course, was highly immunogenic in mice. RAdEs induced high titers of JEV neutralizing antibodies and protected the immunized mice against lethal JEV challenge demonstrating its potential use as a vaccine against JEV infection. The highly immunogenic effect of the recombinant helped achieve the desired results, which were long awaited by the scientific community.
The infection caused by JEV is fatal in nature and absence of long-term immunity had added to the problem. The allergic reactions to the known vaccine had further compounded the problem. However, administration of the vaccine of instant invention is been found to be absolutely safe and free from adverse effects.

Replication-defective recombinant adenoviruses (RAds) were constructed that synthesized the pre-Membrane (prM) and envelope (E) proteins of Japanese encephalitis virus (JEV). Recombinant virus RAdEa synthesized Ea, the membrane-anchored form of the E protein, and RAdEs synthesized Es, the secretory E protein. RAdEa replicated poorly in human embryonic kidney (HEK) 293A cells and 88-folds lower titers of the virus were obtained compared to RAdEs. RAdEa also synthesized lower amounts of E protein in HEK 293A cells as judged by radioimmunoprecipitation and immunofluorescence studies.
Mice were immunized intramuscular (IM) and orally with RAds. Oral route of virus delivery induced low titers of anti-JEV antibodies that had only little JEV neutralizing activity. IM immunizations with both RAdEa and RAdEs resulted in high titers of anti-JEV antibodies. Interestingly, RAdEa induced very low titers of JEV neutralizing antibodies whereas RAdEs inoculation resulted in high titers of JEV neutralizing antibodies. Splenocytes from mice immunized IM with RAds secreted large amounts of interferon-γ and moderate amounts of interleukin-5. These splenocytes also showed cytotoxic activity against JEV-infected cells. Mice immunized IM with RAdEs showed complete protection against the lethal dose of JEV given intra-cerebral.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS
FIG. 1 shows Growth of RAds in HEK 293A cells. Monolayers of HEK 293A cells in 35-mm tissue culture dishes were infected with RAds at a multiplicity of infection (MOI) of 1 and incubated at 37° C. in 3 ml culture medium. At 6 hr interval the cell monolayers were lysed in the culture medium by three cycles of freeze-thawing.

Shown in the figure are mean JEV neutralization titers of serum samples from immunized mice.
FIG. 7 shows Cytokine production by splenocytes from immunized mice. BALB/c mice were immunized with RAdEa, RAdEs or the vaccine by IM or oral route of inoculation as indicated at the top of the figure. These mice were given two booster doses as described in the methods. One week after the second booster dose splenocytes from two mice (indicated by gray and black bars) from each immunization group were cultured in presence of JEV. Culture supernatants were collected each day and stored at -70° C. These were then assayed for IFN-γ, IL-4 and IL-5.

These mice received two booster doses of the immunogen on day 22 and 36 post-immunization. Mice were challenged on day 44 post-immunization with 100 LD50 (50%-lethal dose) of JEV given intra-cerebrally. Mice were observed for mortality for the next three weeks. Shown above is the percentage of surviving mice at a given time point. Immunogen dose and route of inoculation have been indicated. *indicates oral delivery of RAdEs along with the bicarbonate buffer.
The invention is further elaborated with the help of experimental data, as presented below in the form of examples. However, the examples should not be construed to limit the scope of the invention
JEV and cells: The GP78 strain of JEV was used in these studies (44). The virus was grown in neonatal mouse brain. The brain from infected mice was homogenized as a 10% suspension in Eagle's minimal essential medium (EMEM). The suspension was centrifuged and filtered through 0.22 μm sterile filters. The virus was stored at -70° C. in aliquots. Virus titration was carried out by plaque assay on porcine stable kidney (PS) monolayers as described previously (43). Adenovirus was grown in human embryonic kidney (HEK) 293A cells (Quantum Biotechnologies Inc.) cultured in Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% fetal calf serum (FCS).
Construction of recombinant adenoviruses: Recombinant adenoviruses were constructed using the Adeno-X expression system (BD Biosciences) that utilized a ligation-based strategy for producing recombinant virus. Using this system a mammalian expression cassette containing the cDNA encoding JEV E protein was incorporated into a replication incompetent (E1/E3) human adenovirus type 5 (Ad5) genome. Two recombinant adenoviruses (RAds) were made; RAdEa, synthesizing JEV prM and the membrane-anchored E protein, and RAdEs, synthesizing prM and the secretory E protein. Plasmids pMEa and pMEs that contained the cDNAs encoding JEV prM and the membrane-anchored (Ea) or secretory E protein (Es), respectively have been described previously (15). Plasmid pMEa was modified by site-directed mutagenesis to contain an Afl II restriction site down-stream of the 3'-end of the JEV cDNA past the Bam HI site. The JEV cDNA encoding the prM and Ea proteins was excised from the mutated pMEa as a Kpn I-Afl II fragment and cloned at these sites in the adenovirus shuttle plasmid pShuttle (BD Biosciences) under the control of human cytomegalovirus (CMV) immediate early (IE) promoter/enhancer to yield plasmid pSEa. The shuttle plasmid pSEa contained the bovine growth hormone (BGH) polyadenylation signal downstream of the cloned JEV cDNA. The cDNA encoding prM and Es sequence was obtained by digesting pMEs with Kpn I and Bam HI. This cDNA fragment was ligated to the adenovirus shuttle plasmid, pShuttle, digested with Kpn I and Hind III at the Kpn I end. The free Bam HI and Hind III ends were nucleotide filled with T4 DNA polymerase and the blunt ends so created were ligated together to yield plasmid pSEs where JEV cDNA encoding prM and Es was under the control of human CMV IE promoter/enhancer. The shuttle plasmid pSEs contained the BGH polyadenylation signal downstream of the cloned cDNA. The junctions of the shuttle plasmid and the cDNA insert were sequenced to confirm the presence of the cDNA in correct frame. The plasmids pSEa and pSEs were digested with I-Ceu I and Pl-Sce Ito obtain the expression cassettes containing the JEV cDNA together with CMV promoter/enhancer and BGH polyadenylation signal. These were then ligated with I-Ceu I and Pl-Sce I digested adenovirus plasmid pAdeno-X (BD Biosciences) to generate plasmids pAdEa and pAdEs containing the Ea and Es expression cassettes, respectively. Monolayers of HEK 293A cells were transfected with Pac I digested pAdEa and pAdEs using Effectene (Qiagen) and incubated for a week at 37° C. By this time, RAd plaques had begun to show. The cell monolayers were harvested in culture supernatant, frozen-thawed thrice and centrifuged to obtain the released crude recombinant virus that was amplified once in HEK 293A cells and subjected to 2 rounds of plaque purification to obtain recombinant viruses RAdEa and RAdEs.
Radioimmunoprecipitation: Synthesis of JEV proteins by RAdEa and RAdEs was studied by infection of HEK 293A cells followed by radiolabelling and immunoprecipitation. Briefly, monolayers of HEK 293A cells were infected with virus at a multiplicity of infection (MOI) of 1 and incubated at 37° C. After 24 hr, the cell monolayer was radiolabelled by growing in presence of 100 μCi of Easytag® EXpre35S35S protein labeling mix (NEN) for 4 hr. The culture supernatant was harvested and stored at -70° C. The monolayers were harvested in 500 μl of radioimmunoprecipitation assay buffer (10 mM Tris-HCl pH 8.0, 140 mM NaCl, 5 mM Iodoacetamide, 0.5% Triton X-100, 1% Sodium dodecyl sulphate (SDS), 1% Sodium deoxycholate, 2 mM Phenylmethylsulfonyl fluoride). Immunoprecipitation was carried out using mouse anti-JEV serum (ATCC) and Protein A Sepharose beads (Amersham). Immunoprecipitated proteins were electrophoresed on a 12% SDS-polyacrylamide gel that was dried before exposing to X-ray film for autoradiography.
Immunofluorescent staining: Monolayers of HEK 293A cells were infected with RAdEa, RAdEs or JEV at a MOI of 1. The cells were fixed the next day with 2% Paraformaldehyde and permeabilized with 0.1% Triton-X 100. These cells were then stained by incubation with mouse anti-JEV serum (ATCC) followed by anti-mouse IgG-FITC conjugate (Dako) and observed under a microscope using ultra-violet light.
Mice immunization and challenge experiments: All immunizations were carried out on 4-5-week-old inbred BALB/c mice. Each immunization group consisted of 6-8 mice. For IM immunizations, mice were injected in the hind legs with different amounts of RAds diluted in 100 μl phosphate-buffered saline (PBS) using a 30 G needle. Another group of mice was immunized with the mouse brain-derived, formalin-inactivated JEV vaccine manufactured by the Central Research Institute, Kasauli (India). Each mouse was given an IM injection of 100 μl of the vaccine that was 1/10th of the recommended adult human dose. For oral immunizations, water was withdrawn from the mice cages for 6-8 hr and then 200-400 μl virus diluted in PBS or 100 mM Sodium bicarbonate buffer (ph 8.9) was administered per oral using a mouse-feeding needle that had a small balloon at the point of the delivery. Two booster doses, given 3 and 5 weeks after the primary immunization, contained the same amount of immunogen as the primary dose. At 44 days post-immunization, mice were challenged with intra-cerebral inoculation of the lethal dose of JEV. These mice were observed for mortality for the next 3 weeks.
Antibody assays: Titers of anti-JEV antibodies were assayed using an enzyme-linked immunosorbent assay (ELISA). An ELISA plate was coated with C6/36 cell-grown JEV overnight at 4° C. in 0.2 M Sodium carbonate buffer, pH 9.6 (36). The plate was washed with PBS containing 0.1% Tween-20 (PBS-T) thrice and the wells were blocked with 1% Lactogen in PBS-T at 37° C. for 2 hr. The plate was again washed with PBS-T thrice and incubated with 100 μl diluted mice sera per well at 37° C. for 1 hr. Serial two-fold dilutions of sera were assayed starting at a dilution of 1:25. The plate was then washed thrice with PBS-T and 100 μl anti-mouse antibody conjugated to horse radish peroxidase (HRP) (Dako), diluted 1:2000, was added per well, followed by incubation at 37° C. for 1 hr. The antibody-conjugate was removed by washing the plate thrice with PBS-T. The plate was then incubated in dark with 100 μl per well of the substrate o-Phenylenediamine dihydrochloride (0.5 mg/ml) prepared in citrate buffer (1% Citric acid and 1.46% Disodium hydrogen phosphate) at room temperature for 10 min. The reaction was stopped by adding 50 μl of 5 N Sulfuric acid. The absorbance was read at 492 nm in an ELISA plate reader (Spectramax). The reciprocal of the highest serum dilution giving an optical density at least twice that given by the reagent blanks was taken as the ELISA end-point.
The antibody isotyping ELISAs were carried out in a similar fashion, except that in place of anti-mouse IgG-HRP conjugate, anti-mouse IgG 1-HRP or the IgG2a-HRP conjugate (Pharmingen) was added. This was followed by the incubation with the substrate and color development as above.
Plaque reduction neutralization assay: Two fold serial dilutions of sera from the immunized mice (starting from 1:10) were prepared in EMEM containing 5% FCS and antibiotics. Diluted sera were incubated at 56° C. for 30 min to inactivate the complement. The serum sample (100 μl) was then mixed with equal volume of JEV culture supernatant containing 100 plaque-forming units (PFU) of the virus. The virus-antibody mixture was incubated at 37° C. for 1 hr before adding to a 35-mm dish containing ˜70% confluent monolayer of PS cells. The plaque assay was carried out as described. (43). Percent neutralization was calculated by counting the number of plaques in the presence and the absence of the mouse serum. All assays were done in duplicates. Reciprocal of the highest serum dilution giving 50% neutralization was taken as the JEV neutralization titer.
Cytokine ELISA: Spleen cell suspensions were prepared in RPMI 1640 supplemented with 10% FCS and 6×107 splenocytes were incubated with 3×107 PFU of JEV or E. coli-synthesized JEV E protein (10 μg/ml) in a 35-mm dish at 37 μC. Aliquots of culture supernatant were removed every day for the next 4 days and stored at -70° C. Interleukin (IL)-4, IL-5 and interferon (IFN)-γ were assayed using BD OptEIA kits (BD Biosciences) and as per the assay protocols.
Cytotoxic T lymphocyte (CTL) assay: Standard 51Cr-release method as described previously (15) was used for the CTL assays with some modifications. Briefly, for preparation of the responder cells, 3×107 splenocytes were incubated for 4 days with 3×107 PFU of JEV in a 35-mm dish in RPMI 1640 medium supplemented with antibiotics, 0.5 mM β-Mercaptoethanol, 0.32 mg/ml L-Glutamine, 0.1 mg/ml non-essential amino acids, 0.12 mg/ml Sodium pyruvate and 5% FCS at 37° C. The cells thus generated were referred to as the effector cells. Virus-infected target cells were prepared by infecting P388D1 cells with JEV for 48 hr at a MOI of 1 followed by incubation with 100 μCi of Na251CrO4 (NEN) and subsequent washings to remove free 51Cr.
For carrying out the CTL assay, various numbers of effector cells were incubated at 37° C. for 6 hr with 2×104 51Cr-labelled virus-infected cells by briefly centrifuging them at 100 g for 4 min in a 96-well round bottom plate. At the end of the incubation period, 100 μl of cell-free supernatant was removed and the 51Cr release was counted using a gamma counter (LKB). Triplicate estimations were done in all the assays and the percentage lysis was calculated using the following formula. Percent lysis=[(cpm released in the presence of effector cells-cpm released due to spontaneous leakage)/(total cpm released by 0.2% Triton X-100 lysis-cpm released due to spontaneous leakage)]×100.
Statistical analysis: The statistical significance of different findings between mouse groups was determined by Student's t test. P<0.05 was considered to be significant.
Replication of RAds and synthesis of JEV proteins: The JEV E protein is 500 amino acids long membrane-anchored protein. We have earlier shown that deletion of the C-terminal 102 amino acids of JEV E protein leads to efficient secretion of the truncated protein into the cell surroundings (15). We had also shown that quality of immune responses in mice induced by the secretory E protein were different from those induced by the membrane-anchored E protein (15). Besides, vaccinia recombinants expressing the secretory E protein of Japanese encephalitis or Dengue viruses devoid of the membrane anchor sequence were found to be highly immunogenic in mice (14, 27, 37). We, therefore, constructed two recombinants, RAdEa synthesizing prM and Ea (full-length membrane-anchored JEV E protein) and RAdEs synthesizing prM and Es (398 amino acid secretory E protein). The JEV prM was included in our constructs as its co-synthesis was necessary for correct processing and folding of the E protein (18, 25). The presence of appropriate JEV cDNA in genomes of RAds was established by polymerase chain reaction using JEV genome sequence-specific oligonucleotide primers.
Replication of RAds was studied in HEK 293A cells infected at a MOI of 1. FIG. 1 shows that a major burst in viral titers was observed both for RAdEa and RAdEs between 18 and 24 hr post-infection (PI) after which there was only a marginal increase in titers. RAdEs titer was ˜40-fold higher than that of RAdEa at 24 hr PI. Following the virus replication, the cytopathic effects were first visible at 30 hr PI for both RAdEa and RAdEs. The cytopathic effects had become highly pronounced by 42 hr PI when almost 80% cells had come off the surface of the tissue culture plates. At this time point titer of RAdEs was 1.2×107 PFU/ml, which was 88-times higher than that of RAdEa. These results showed that compared to RAdEs, RAdEa replicated poorly in HEK 293A cells. We studied four independent isolates of RAdEa and found all them to be slow growers.
The synthesis of JEV proteins by RAds was studied in HEK 293A cells that were infected with different viruses followed by radiolabelling and immunoprecipitation of JEV proteins using mouse anti-JEV serum. FIG. 2 shows that RAdEa-infected cell lysate had 2 proteins of apparent molecular masses of 51 and 23 kDa that corresponded with JEV E and prM proteins. None of these proteins were detectable in the culture supernatant of the infected cells. The RAdEs-infected cell lysate showed the synthesis of Es and prM proteins of apparent molecular masses of 45 and 23 kDa, respectively. The culture supernatant from the RAdEs-infected cells had a significant amount of Es, indicating that the E protein synthesized by RAdEs was secretory.
Use of increased amounts of anti-JEV antibody and Protein A Sepharose in immunoprecipitations did not result in precipitation of enhanced amounts of E protein indicating that the amounts of these reagents used were not limiting. Scanning of the autoradiograph with optically-enhanced densitometer using `Diversity One` software (version 1.6, PDI, New York) followed by calculations based on the volumes of the lysate or the supernatant loaded on the gel, suggested that the secretory E protein present in the culture supernatant constituted about 76% of the total E protein synthesized by RAdEs-infected cells. Furthermore, levels of total Es protein synthesis were around 20-fold higher than the levels of Ea protein. Immunofluorescent staining of RAdEa- and RAdEs-infected HEK 293A cells further confirmed that levels of Ea protein were significantly lower than that of the Es protein (FIG. 3). The lower levels of Ea synthesis may be related to the poor growth of RAdEa in HEK 293A cells.
We found that RAdEa synthesizing the membrane-anchored E protein grew slowly and achieved 88-fold lower titers in HEK 293A cells when compared with RAdEs synthesizing the secretory E protein. Infection of HEK 293A cells with the recombinants followed by radioimmunoprecipitation of JEV proteins showed that RAdEa synthesized lower amounts of JEV E protein. This was corroborated by the low levels of immunofluorescence on RAdEa-infected HEK 293A cells when compared with RAdEs-infected cells. HEK 293A cells support replication of E1-deleted RAds reported in this work as these cells contain Ad5 E1 transcription unit permanently integrated in them. In other mammalian cells these RAds are unable to replicate for the want of the E1 sequences. However, expression of the foreign gene does take place, which is under the independent control of the CMV IE promoter. We have studied expression of JEV E protein by RAds in PS cells by immunofluorescence and radioimmunoprecipitation. No significant differences were found in the levels of E protein synthesis in PS cells infected with RAdEa or RAdEs at a MOI of 1.
The adenovirus vector used in our studies had deletions in both the E1 and E3 transcription units that allow packaging of up to 8 Kb foreign DNA in the recombinant virus. The size of JEV expression cassette inserted in RAdEa was ˜3.3 Kb which was well within the packaging limits of the recombinant virus. The reason for lower titers of RAdEa in HEK 293A cells is, thus, not clear. Previously, we found no differences in the levels of expression of membrane-anchored or secretory E protein of JEV when HEK 293A cells were transfected with expression plasmids containing the Ea or Es genes under CMV IE promoter (15). This observation together with our results in the PS cells on E protein synthesis indicates that lower levels of E protein synthesis by RAdEa in HEK 293A cells are related to the low levels of its replication.
Anti-JEV antibody response in mice immunized with RAds: Groups of BALB/c mice were immunized with RAdEa or RAdEs delivered orally or IM. The antibody response of these mice was compared with those immunized with formalin-inactivated commercial JEV vaccine. Serum samples collected from mice at various time points were assayed for anti-JEV end-point ELISA titers. FIG. 4 shows that anti-JEV antibodies were detectable in all immunization groups on day 20 post-immunization and these titers increased further on days 28 and 44 post-immunization following the booster doses. Compared to IM immunization, antibody titers were drastically low in mice immunized orally with RAds. For example, compared to oral immunization, 1×108 PFU of RAdEs given IM induced ˜60-fold higher antibody response on day 44. For both the oral as well as IM immunizations, higher antibody titers were obtained when higher doses of RAd were used. No significant differences were seen in day 44 anti-JEV antibody titers of mice immunized IM with 7.5×105 PFU of RAdEa or RAdEs. IM immunizations with RAds induced significantly higher antibody titers than those induced by IM inoculation of the vaccine. Thus, the lower dose of RAdEa and RAdEs (7.5×105 PFU) gave ˜60-fold higher antibody titers after the second booster when compared with the titers obtained with the vaccine. At the higher dose of 1×108 PFU, RAdEs induced ˜250-fold higher titers than the vaccine on day 44.
Some investigators have carried out oral immunization of mice with RAds using Sodium bicarbonate buffer to neutralize the acid pH of the stomach (11, 40, 47). However, there are others who have carried out oral immunization of mice with RAds without the use of any buffer (3, 9, 42, 48). We have compared the immunogenicity in mice of RAdEs given orally (1×108 PFU) with or without the bicarbonate buffer. FIG. 4 shows that no advantage was offered by the use of bicarbonate buffer during oral immunization with RAdEs. In fact, no effect of booster doses was seen when RAdEs was delivered orally using bicarbonate buffer and antibody titers on day 44 post-immunization were lower than in those mice that received the virus without bicarbonate buffer.
Isotype analyses of anti-JEV antibody produced by immunized mice: In order to analyze the quality of immune responses generated by the RAds, end-point titers of anti-JEV IgG1 and IgG2a antibodies were determined by ELISA. FIG. 5 shows that at lower dose of RAds given orally (3×106 PFU) titers of anti-JEV IgG1 and IgG2a antibodies were below 25. When a higher dose of RAdEs (1×108 PFU) was given orally, the majority of antibodies were of IgG1 type; the ratio of IgG1/IgG2a titers in this case was 6.48 indicating a Th2 type of immune response. When RAds were delivered through IM route, the anti-JEV antibody response was almost exclusively of IgG1 type. In case of mice immunized IM with RAdEa (7.5×105 PFU), IgG1/IgG2a titer ratio was 68 and it was 64 in the case of RAdEs (7.5×105 PFU)-immunized mice. At higher dose of 1×108 PFU, RAdEs again induced predominantly IgG1 type of anti-JEV antibodies; the ratio of IgG1/IgG2a titers in this case was 25. These results indicated that RAdEa and RAdEs induced an almost exclusive Th2 kind of immune response in mice when delivered IM. The IM immunization of mice with the vaccine also induced IgG1 dominated antibody response indicating a Th2 type immune response.
JEV neutralizing antibody response in mice immunized with Rads: Titers of JEV neutralizing antibodies were determined in serum samples obtained from the immunized mice at day 44 post-immunization. FIG. 6 shows that oral route of immunization induced very low JEV neutralizing antibodies. Similar to ELISA titers, the JEV neutralizing antibody titers were lower in mice immunized orally with RAdEs plus the bicarbonate buffer compared to titers in those mice immunized with RAdEs without the bicarbonate buffer, although the difference was statistically insignificant. Compared to RAdEa, RAdEs given IM induced higher JEV neutralizing titers and these were enhanced further when higher dose of virus was used for immunization. IM immunization with RAdEs induced significantly higher JEV neutralizing antibody titers than those induced by the vaccine.
Cytokine secretion by splenocytes from immunized mice: Splenocytes prepared from the immunized mice were cultured in presence of JEV and synthesis of IFN-γ, IL-4 and IL-5 was studied on each day for the next 4 days. FIG. 7 shows that splenocytes from mice immunize with RAdEa or RAdEs by IM route secreted large amounts of IFN-γ. Splenocytes from mice immunized with the recombinant viruses through oral route made only small amounts of IFN-γ. Similarly, mice immunized with the vaccine made only small amounts of IFN-γ. Splenocytes from IM-immunized mice also made moderate amounts of IL-5 which was almost absent in the case of orally immunized mice or mice immunized with the vaccine. IL-4 was not detectable in any of the cases; the detection limit of IL-4 ELISA was 7.8 pg/ml. Similar pattern of cytokine secretion was observed when splenocytes were cultured in presence of JEV E protein
CTL activity in immunized mice: To study the generation of memory CTLs, splenocytes from immunized mice were stimulated in vitro with JEV and examined for cytotoxic activity against cells infected with JEV. FIG. 8 shows the results of CTL assays at various effector to target cell ratios. Thus, mice immunized with RAdEa or RAdEs through IM route showed significant CTL activity. No CTL activity was detectable in mice immunized with RAdEa or RAdEs through oral route. Similarly, unimmunized and Ad5-immunized mice or those immunized with the vaccine showed no CTL activity.
Mice challenge studies: Mice immunized with RAds were challenged at day 44 post-immunization by intra-cerebral inoculation of a lethal dose (100 LD50) of JEV. These mice were observed for mortality for 3 weeks after the challenge. All mice immunized with 7.5×105 or 1×108 PFU of RAdEs given IM survived the challenge while none of the unimmunized mice survived. Furthermore, none of the mice immunized IM or orally with 1×108 PFU of E1/E3 Ad5 survived the challenge. About 50-60% protection was seen in mice immunized with 1×108 PFU of RAdEs given orally. The level of protection was lower (30%) when mice were immunized orally with lower doses of RAdEs (3×105 PFU). The level of protection afforded by RAdEa immunization was very low; about 40% mice survived from those immunized with 7.5×105 PFU given IM and only about 20% mice survived from the group immunized with 3×106 PFU given orally. In a separate experiment, 15 mice were immunized with 1×108 PFU of RAdEs and given 2 booster doses on day 21 and 35. When challenged on day 44 post-immunization with 1000 LD50 of JEV, given intra-cerebral, 100% of the immunized mice survived.
The flavivirus E protein has been the antigen of choice for vaccine development using modern methods of vaccinology such as the DNA vaccination or the use of recombinant virus for antigen delivery (10, 12, 16, 28-31). This has been so because E protein plays an important role in a number of processes, including viral attachment, membrane fusion and entry into the host cell (26). Besides, flavivirus E protein induces virus-neutralizing antibodies and CTLs (14, 14, 15, 22, 23, 34). It has been shown that protection against JEV is mainly antibody dependent, and virus-neutralizing antibodies alone are sufficient to impart protection (19, 32). This was also implied from our previous observation that the formalin-inactivated JEV vaccine, which did not induce CTLs, provided protection to vaccinees against JEV (15). Thus, with a view to develop a recombinant virus-based JEV vaccine, we have constructed RAds synthesizing JEV E protein.
During replication of JEV, the E protein is expressed on the cell surface. Plasmid DNA vectors have been described that synthesize different forms of the E protein, such as the cytoplasmic, membrane-anchored or secretory (2, 6, 7, 15, 20). These different forms of JEV E protein were shown to induce different kind of immune responses. Similarly, recombinants of vaccinia expressing the secretory E protein of Japanese encephalitis or Dengue viruses were found to be highly immunogenic in mice (14, 27, 37). Previously, we had shown that truncated JEV E protein, where the membrane-anchor sequence had been removed by deletion of the C-terminal 102 amino acids, was actively secreted in the cell surroundings (15). We have now constructed RAds that synthesize the membrane-anchored or the secretory E protein.
Oral delivery of RAd has been shown to induce humoral and cellular immune responses to the protein encoded by the transgene, however, these responses have usually been weaker compared to those induced by the IM or intra-peritoneal delivery of RAd (21, 35, 42). In the present study too, oral immunization of mice by RAds resulted in significantly lower anti-JEV antibody titers when compared with the IM route of RAd delivery. Thus, mice immunized IM with 1×108 PFU of RAdEs gave ˜60-fold higher anti-JEV antibody response than those immunized with the same dose of the virus given orally.
Use of Sodium carbonate buffer to neutralize the pH of the stomach made no perceptible difference to antibody titers when compared with the antibody titers induced by RAdEs given orally without the bicarbonate buffer. In fact, when bicarbonate buffer was used during oral immunization, the booster doses of RAdEs failed to enhance the anti-JEV antibody titers. For RAdEa too, oral delivery resulted in weaker anti-JEV antibody responses compared to the IM delivery of the recombinant. Thus, compared to oral delivery, IM inoculation of 7.5×105 PFU of RAdEa (which was half the dose given orally) induced ˜100-fold higher anti-JEV antibody titers. The antibody titers were dose dependent. Thus higher doses of RAdEs (1×108 PFU) delivered orally induced higher anti-JEV antibody titers. These titers were ˜4-fold higher than those induced by the commercial vaccine given IM. Importantly, IM inoculation of RAdEa or RAdEs at both the doses tested (7.5×105 and 1×108 PFU) resulted in significantly higher antibody responses than those given by the vaccine; 1×108 PFU of RAdEs given IM induced ˜250-fold higher titer than the vaccine. Similar pattern was reflected in JEV neutralizing antibody titers when oral route of RAds delivery was compared with the IM route although the differences weren't so pronounced. Thus ˜20-fold higher JEV neutralizing antibody titers were induced by IM inoculation of 1×108 PFU of RAdEs compared to oral delivery of the recombinant. Only statistically insignificant differences were noted in anti-JEV antibody titers induced by 7.5×105 PFU of RAdEa and RAdEs given IM. However, there was significant difference in the JEV neutralizing antibody titers generated by the two RAds; a mean JEV neutralizing antibody titer of 10 was obtained when mice were immunized with RAdEa whereas it was 133 when mice were immunized with RAdEs. Higher JEV neutralizing antibody titers were recorded when higher doses of RAdEs were used for immunization. At both the doses tested (7.5×105 and 1×108 PFU) IM inoculation of RAdEs induced significantly higher JEV neutralizing antibody titers than the commercial vaccine. Thus a dose of 1×108 PFU of RAdEs given IM induced 8-fold higher JEV neutralization titer than the vaccine. These differences in JEV neutralizing antibody titers induced by RAdEa and RAdEs by oral and IM inoculation were reflected in the level of protection afforded by these recombinants to the immunized mice against lethal JEV challenge. Thus both doses of RAdEs inducing JEV neutralizing antibody titers higher than the vaccine gave 100% protection. Immunization with RAdEs or RAdEa given orally gave only low levels of protection. Challenge experiments indicated that mice immunized IM with the adenovirus synthesizing the membrane-anchored form of JEV E protein did not develop protective immunity whereas those immunized with recombinant synthesizing the secretory form of JEV E protein developed robust anti-JEV protective immunity resulting in 100% protection. These results show that RAd-based JEV immunizations are superior to naked DNA immunizations, which imparted only about 50-60% protection in a mouse challenge model (15). It is interesting that level of protection was similar (50-60%) when mice were immunized with plasmid DNA synthesizing Ea or Es proteins (15) whereas in the present work Es induced significantly superior protective immune response than the Ea protein. This may be related to a more efficient delivery of JEV transgene using RAd than the direct injection of naked plasmid DNA for immunization. Our finding is, however, consistent with reports from others where truncated form of JEV or Dengue E protein (leading to its secretion) was found to be more immunogenic than the membrane-anchored form of the E protein (14, 37).
Poor anti-JEV antibody induction by oral immunization with RAds was also reflected in poor cytokine secretion by splenocytes in presence of JEV. While very little IFN-γ was secreted by splenocytes from mice immunized orally with RAdEs or RAdEa, significant amounts of IFN-γ were secreted by splenocytes obtained from mice immunized IM with RAdEa or RAdEs. Splenocytes from IM immunized mice also synthesized moderate amounts of IL-5 that was not detectable in cultures of splenocytes obtained from mice immunized orally with RAds. Mice immunized IM with both RAdEa and RAdEs had significant CTL activity, which was undetectable in mice immunized orally with RAds or IM with the vaccine. Oral immunization with RAdEs at lower dose resulted in IgG1 dominated immune responses; ratio of IgG1/IgG2a end-point titers was 6.5. This is consistent with studies on oral immunization of mice with RAd synthesizing rabies glycoprotein where abundance of anti rabies IgG1 was recorded (46). The IM inoculation of RAdEa and RAdEs also resulted in preponderance of IgG1 kind of antibodies. No data could be found in literature on antibody isotypes when adenovirus recombinants are delivered IM. Our results indicating the preponderance of IgG1 type antibodies, secretion of IFN-γ and IL-5 by splenocytes and induction of CTLs suggest that IM inoculation of mice with RAds synthesizing JEV E protein activates both the humoral and the cellular arms of the immune system, and immune responses of both Th1 and Th2 type are induced.
The results presented in this invention show that RAd synthesizing the secretory form of JEV E protein imparted robust immunity in mice against lethal dose of JEV given intra-cerebral. This makes RAdEs a potential candidate vaccine against JEV. Further, safety profile of the vaccine of the instant application was studied. The vaccine is found to be safe for administration. None of the immunized mice showed any obvious complications.
