Definitions
- the present invention relates to genes of particular strains of feline calicivirus, to the proteins encoded by these genes, and their use for the production of immunogenic preparations and recombinant vaccines or subunits against feline calicivirosis. These immunogenic preparations and these vaccines can also be combined with immunogenic preparations or vaccines prepared on the basis of other feline pathogens, for the production of immunogenic preparations and multivalent vaccines.
- Feline caliciviruses in English Feline Calicivirus or FCV were first described in 1957 (Fastier LB Am. J. Vet “ . Res. 1957. 18. 382-389). Feline caliciviruses are with feline herpes viruses the two main sources of viral diseases of the upper respiratory tract in cats. FCV viruses affect a large number of animals, with FCV carriage rates of around 15 to 25%, and an anti-FCV seroprevalence of 70 to 100% (Coutts et al. Vet. Rec. 1994. 135. 555-556; Ellis TM Australian Vet. J. 1981. 57. 115-118; Harbor et al. Vet. Rec. 1991. 128. 77- 80;..
- FCV Fibre Channel virus
- Transmission of the FCV virus occurs only horizontally, there is no vertical transmission from the mother to her kitten during gestation (Johnson R.P. Res. Vet. Sci. 1984. 31. 114-119). Transmission of FCV is by contact between infected animals and healthy animals or by air during sneezing (Wardley RC. Arch. Virol. 1976. 52. 243-249).
- Feline caliciviruses are naked viruses of the family Caliciviridae, they are provided with a positive single-stranded RNA, of a size of approximately 7.7 kilo base pairs (kbp) (Carter MJ Arch. Virol. 1994. 9. 429-439). Like many RNA viruses, great heterogeneity exists within the FCV viral population. The antigenic variations, brought to light at the beginning of the 1970s by experiments in cross-neutralization, make it possible to classify the FCV into several viral strains or quasi-species (Radfoord et al. Proc. 1 st Int. Symp. Caliciviruses ESVV 1 997 . 93-99).
- FCV strains have been isolated and sequenced, in particular the F9 strain (Carter et al. Arch. Virol. 1 992. 122. 223-235, sequence deposited in the GenBank database under the access number M86379), CFI (Neill et al. J. Virol. 1 991. 65. 5440-5447, GenBank access number U13992 and M3281 9), Urbana or URB (Sosnovtsev and Green Virology 1 995. 210. 383-390, access number GenBank L40021), F4 (Tohya et al. Arch. Virol. 1 991. 1 17. 173- 1 81, GenBank access numbers D31 836 and D90357), KCD (Fastier LB Am. J.

- 255 Kann and Gillepsie. Cornell Vet. 1 970. 60. 669-683, GenBank access number U07130
- FCV Vaccination against FCV has been implemented since the late 1970s using attenuated FCV strains, mainly the F9 strain isolated in 1958 by Bittle (Bittle et al. Am. J. Vet. Res. 1 960. 21. 547-550) or strains derived from F9 by passage in vitro or in vivo ("F9-like").
- Inactivated vaccines are also available. They use strains 255 and 2280, isolated respectively in 1970 in a cat presenting with pneumonia (Kahn and Gillepsie. Georgia Vet. 1970. 60. 669-683) and in 1983 in a cat suffering from lameness (Pedersen et al. Fel Prac. 1 983. 13. 26-35).
- the humoral response is essentially directed against the capsid protein, also called p65 (Guiver et al. J. Gen. Virol. 1992. 73. 2429-2433).
- the genes coding for the capsid protein of many feline caliciviruses have been sequenced and compared without any particular distinction being made (Glenn et al. Proc. 1 st Int. Symp.
- Caliciviruses ESVV 1 997. 106-1 10 Geissier et al. Virus Res. 1 997. 48. 1 93-206; Neill et al. Proc. 1 st Int. Symp. Caliciviruses ESVV 1997. 120-124).
- the gene coding for the capsid protein has also been cloned and expressed in various expression systems, in particular the gene coding for the capsid protein of the FCV KS20 virus in plasmids (Geissier et al. J. Virol. 1999. 73.
- antisera produced against old vaccine strains isolated in the 60s and 70s such as strains F9, 255 or 2280, neutralize only a few isolates from the 90s.
- the anti-F9 serum neutralizes 43% of the isolates from the period 1990-96, against 56% for the period 1980-89 and 86% for the period 1958-79, and only 10% of the English isolates from the period 1990-96 (Lauritzen et al. Vet. Microbiol. 1997. 56. 55-63).
- the present invention aims to demonstrate strains of FCV, inducing in cats antibodies having a broad spectrum of cross neutralization.
- the invention has in particular for objective, from the selected strains, the isolation and the characterization, of genes coding for immunogenic proteins usable for vaccination against feline calicivirosis.
- Another objective of the invention is to provide recombinant in vitro and in vivo expression vectors containing and expressing at least one such nucleotide sequence.
- Yet another object of the invention is to provide immunogenic preparations or vaccines against feline calicivirosis.
- Yet another objective of the invention is to provide multivalent immunogenic preparations and multivalent vaccines against feline calicivirosis and against at least one other feline pathogen.
- the invention relates essentially to two FCV strains obtained by pharyngeal swabs practiced in France and in the United Kingdom on cats showing signs of infection by feline caliciviruses. They are respectively strain G1 (deposited at the National Collection of Cultures of Microorganisms (or CNCM) of the Institut Pasteur, Paris, France, under the access number 1-2167) and strain 431 (deposited at CNCM under access number 1-2166), both deposited on March 12, 1999.
- CNCM National Collection of Cultures of Microorganisms
- FCV G1 strain isolated in France does not correspond to the FCV strain isolated in the United Kingdom in 1978 by Tohya (Tohya Y. et al. Jpn. J. Sci., 1990, 52, 955-961) and also named G1.
- FCV 431 and G1 strains were carried out by cross-neutralization tests against FCV isolates from a reference panel.
- This reference panel is made up of 18 current FCV isolates taken from cats showing signs of infection by feline calicivirus and coming from three distinct geographical areas. 7 isolates are American, these isolates are identified RMI1, RMI2, RMI3, RMI5, RMI6, RMI7 and RMI9. 7 isolates are French, they are designated A2, F1, G1, G3, F3031, H3-2 and H1 -4. The last 4 isolates are English, they are designated 431, 388b, 337 and J5.
- strains of the panel are available from the depositor on request. They were also published in an article in the journal “Archives of Virology” (Poulet et al. Arch. Virol. February 2000. 145 (2). 243-261), available online on the Internet at the time of filing with the publisher.
- FCV 431 strain a dominant strain which can be used for the protection of felines and in particular cats against most FCV strains. Thanks to the panel of ⁇ FCV strains disclosed here, it is possible for a person skilled in the art to select other dominant FCV strains. By equivalence, the invention also covers, through the FCV 431 strain, the FCV strains equivalent to the latter, having antibodies with a broad spectrum of cross-neutralization.
- FCV strain seroneutralizes another FCV strain when the heterologous seroneutralization titer is greater than or equal to 1.2 log 10 VN 50 (Povey C. and Ingersoll J., Infection and Immunity, 1975, 11, 877 -885). The applicant took this value as the positivity threshold. However, cross-neutralization results of an isolated t â FCV with a counterpart as lower serum neutralization or equal to 2 log 10 VN 50 can not be interpreted.
- a second method for establishing the equivalence of an FCV strain vis-à-vis the FCV 431 strain is to use monoclonal antibodies specific for the FCV 431 strain and to test the candidate FCV strain by indirect immunofluorescence (IFI).
- IFI indirect immunofluorescence
- the applicant has thus succeeded in producing several monoclonal antibodies which have been found to be specific for strain 431.
- One of them has been named 44.
- This monoclonal antibody and the corresponding hybridoma are available from the applicant on request and are also disclosed in the article by Poulet et al. supra.
- the other FCV G1 strain was chosen for its complementarity with respect to the FCV 431 strain, namely that the combination of the 431 and G1 anti-sera seroneutralize 100% of the isolates from the reference panel. that is to say that the FCV G1 strain has a homologous seroneutralization titer greater than or equal to 2 log ⁇ 0 VN 50 and heterologous seroneutralization titers greater than or equal to 1, 2 log 10 VN 50 vis-à-vis the FCV isolates of reference panel against which the anti-serum 431 does not seroneutralize or weakly (value less than 1.2 log 10 VN 50 ).
- the invention also covers the equivalent FCV strains having the same complementarity with respect to the FCV 431 strain. It is also possible to produce and select antibodies specific for this strain, which makes it possible to determine equivalents on this other basis.
- the applicant has also succeeded in isolating, characterizing and sequencing the capsid gene of FCV 431 and FCV G1, the capsid protein, and has determined the corresponding cDNA (complementary DNA) sequences,
- the subject of the invention is therefore a nucleic acid fragment comprising all or part of the nucleotide sequence coding for the capsid protein - of virus 431, the amino acid sequence of which is shown in SEQ ID NO: 7 or in the figure. 2, or an immunologically active fragment of this protein, that is to say an epitope, peptide or polypeptide substantially retaining the immunogenic activity of the capsid protein.
- the subject of the invention is in particular a DNA fragment comprising the cDNA sequence of SEQ ID NO: 6 or a fragment retaining the essential properties of the complete sequence, that is to say coding for a peptide, polypeptide or epitope substantially retaining the immunogenic activity of the capsid protein.
- the subject of the invention is in particular a DNA fragment comprising this cDNA sequence, in particular coupled with elements for regulating transcription. It goes without saying that the invention automatically covers the nucleic acid fragments, DNA fragments and equivalent cDNA sequences, that is to say FCV capsid specifics which do not change the functionality or the strain specificity of the described sequence or of the polypeptides encoded by this sequence. Of course, the sequences which differ by degeneration of the code will be included.
- the invention also automatically covers the equivalent nucleotide sequences (RNA, DNA, cDNA) in the sense that they code for an FCV capsid protein, or a peptide, polypeptide or epitope specific for FCV capsid protein, capable of inducing in vivo in the feline species, in particular in the cat, antibodies having substantially the same spectrum of cross neutralization as the antiserum of the FCV 431 strain.
- RNA, DNA, cDNA equivalent nucleotide sequences
- the subject of the invention is also a nucleic acid fragment comprising all or part of the nucleotide sequence coding for the capsid protein of the G1 virus as represented in SEQ ID NO: 5 or in FIG. 1, or a fragment immunologically active of this protein, that is to say an epitope, peptide or polypeptide substantially retaining the immunogenic activity of the capsid protein.
- the subject of the invention is in particular a DNA fragment comprising the cDNA sequence of SEQ ID NO: 4 or a fragment retaining the essential properties of the complete sequence, that is to say coding for a peptide, polypeptide or epitope substantially retaining the immunogenic activity of the capsid protein.
- the subject of the invention is in particular a DNA fragment comprising this cDNA sequence, in particular coupled with elements for regulating transcription. It goes without saying that the invention automatically covers the nucleic acid fragments, DNA fragments and equivalent cDNA sequences, that is to say the fragments and nucleotide sequences which do not change the functionality or the strain specificity of the described sequence or polypeptides encoded by this sequence. Of course, the sequences which differ by degeneration of the code will be included.
- the invention also automatically covers the equivalent nucleotide sequences (RNA, DNA, cDNA) in the sense that they code for a peptide, polypeptide or epitope capable of inducing in vivo in the feline species, in particular in the cat, antibodies having substantially the same cross-neutralization spectrum as the antiserum of the FCV G1 strain.
- RNA, DNA, cDNA equivalent nucleotide sequences
- the gene coding for the capsid protein of the FCV G1 and FCV 431 viruses has a size of 2007 nucleotides for FCV 431 and 2010 nucleotides for FCV G1.
- the capsid protein has a size of 668 amino acids for FCV 431 and 669 amino acids for FCV G1, and a mass of 60-65 kDa (protein p65).
- the subject of the invention is also an expression vector comprising at least one DNA fragment according to the invention, in particular a type 431 cDNA or a
- the expression vector comprises a cDNA type 431 and a cDNA type G1.
- type is meant that the cDNA is complementary to an RNA sequence of the strain considered.
- These expression vectors can be poxviruses, for example the vaccinia virus, avipox (canarypox, folwpox), including species-specific poxviruses (swine pox, raccoonpox and camelpox), adenoviruses and herpesviruses, such as feline herpes viruses (eg FR-A-2,741,806).
- poxviruses for example the vaccinia virus, avipox (canarypox, folwpox), including species-specific poxviruses (swine pox, raccoonpox and camelpox), adenoviruses and herpesviruses, such as feline herpes viruses (eg FR-A-2,741,806).
- poxviruses for example the vaccinia virus, avipox (canarypox, folwpox), including species-specific poxviruses (
- insertion strategies can be used for the expression of several heterologous nucleotide sequences from the same expression vector in vivo. These insertion strategies are in particular the use of a double expression cassette having an opposite orientation, or the use of a double expression cassette having an identical orientation, or else a multiple expression cassette with a "IRES" element (Internai Ribosome Entry Site) located between each insert (patent EP-A1 -0803573).
- the heterologous nucleotide sequences are inserted under the dependence of transcriptional regulatory signals and in particular of promoters, preferably provided during insertion. It is however not excluded to express these heterologous nucleotide sequences under the control of signals specific to the expression vector used.
- one of the preferred promoters is the H6 vaccine promoter (Taylor J. et al. Vaccine, 1988, 6, 504-508; Guo P. et al. J. Virol., 1989, 63, 4189 -4198; Perkus M. et al. J. Virol., 1989, 63, 3829-3836).
- the expression vectors in vivo can also be plasmids.
- the term piasmid is intended to cover any DNA transcription unit in the form of a polynucleotide sequence comprising a cDNA sequence according to the invention and the elements necessary for its expression in vivo. We prefer the circular piasmid form, supercoiled or not. The linear shape also falls within the scope of this invention.
- Each piasmide comprises a promoter capable of ensuring, in the host cells, the expression of the cDNA inserted under its dependence. This is in general a strong eukaryotic promoter and in particular a cytomegalovirus early promoter CMV-IE, of human or murine origin, or 'possibly of another origin such as rat or guinea pig.
- the promoter is either of viral origin or of cellular origin.
- viral promoter other than CMV-IE there may be mentioned the early or late promoter of the SV40 virus or the LTR promoter of the Rous Sarcoma virus.
- cell promoter mention may be made of the promoter of a cytoskeleton gene, such as for example the desmin promoter, or even the actin promoter.
- a subfragment of these promoters, retaining the same promoter activity is included in the present invention, eg the CMV-IE promoters truncated according to WO-A-98/00166.
- the plasmids can also comprise other transcriptional regulatory elements, such as for example intron-type stabilizing sequences, preferably intron II of the rabbit ⁇ -globin gene (van Ooyen et al. Science, 1979, 206: 337-344), signal sequence of the protein encoded by the tissue plasminogen activator gene (tPA; Montgomery ef al. Cell. Mol. Biol. 1997, 43: 285-292), and polyadenylation signal (polyA) , including the bovine growth hormone (bGH) gene (US-A-5 122 458) or the rabbit ⁇ -globin gene.
