Definitions
- the subject of the invention is new vectors for delivering genetic material for i.a. use. in gene therapy, immunotherapy or as a therapeutic or prophylactic vaccine.
- the transfer of genetic material can be carried out according to various operating methods which, for the best known, are (i) transfer by viral vectors, (ii) transfer via encapsulation in liposomes or the like, (iii) transfer mediated by facilitating agents such as cationic lipids, gold beads or calcium phosphate and (iv) transfer by simple injection of naked DNA, i.e. -to say devoid of any other element which can enter into interaction or cooperation with DNA in order to promote its transfer
- viral vectors such as the vaccine vectors are particularly suitable
- vaccine vectors may be suitable.
- the latter will be preferred to retroviral vectors, in particular for preventive vaccination.
- the papillomavirus capsids can be reconstituted in vitro, in the presence of heterologous DNA or RNA, and that this genetic material is effectively encapsulated therein.
- the capsids commonly called VLPs for virus-like particles, can be used as a vehicle for the transfer of genetic material, with various applications.
- Papillomaviruses are small, non-enveloped DNA viruses of icosahedral structure. Their genome codes for up to eight early proteins and two late proteins. The open reading frames are listed from El to E7 without forgetting Ll and L2. The early genes (E for early) are associated with viral replication and cell transformation functions.
- the papillomavirus capsids are made up of the two proteins L, and L 2 (L for late proteins), L being the major constituent A detailed information can be found in Virology, Second Ed by BN Fieids, Raven Press (1990)
- VLPs imitating in all points the capsids of native virions can be obtained by recombinant expression either of L, only, or of L, + L 2 , in the vaccine system (Hagensee et al, J Virol (1993) 67 315) or in the baculovirus system (Kirnbauer et al, PNAS (1992) 89 12180, Kirnbauer et al, J Virol (1993) 67 6929, Rose et al, J. Virol (1993) 67 1936, Le Cann et al, FEMS Microbiol Lett (1994 ) 117.269)
- VLPs adopt a native conformation and react with neutralizing antibodies known to recognize conformational epitopes present in native virions, it has already been suggested to use these VLPs as a vaccine against papillomavirus infections (WO 94/5792)
- HPV human papillomaviruses
- bovine papillomaviruses and human papillomaviruses HPV
- different types of HPV are the cause of various diseases
- Types 1, 2, 3, 4, 7, 10, and 26 - 29 are the cause of benign warts
- Types 5, 8, 9, 12, 14, 15, 17, 19 -25, 36, and 46 - 50 can induce lesions in immunologically deficient individuals
- Types 6, 1 1, 34, 39, 41 - 44 and 51 - 55 are responsible for dysplasias or non-malignant warts genital and respiratory mucosa; in rare cases, some of these types can be found in invasive carcinomas
- types 16 and 18 and to a lesser extent 31, 33, 35 and 45 cause epithelial dysplasias of the genital mucosa and are very widely associated with majority of invasive carcinomas
- the present invention provides, for its part, non-infectious papillomavirus viral pseudo-particles (VLPs) which comprise a capsid delimiting an internal space and a nucleic acid molecule contained in this internal space; the molecule nucleic acid being different from the genome of a papillomavirus at least in that it is devoid of all or part of the regions of said genome coding for late wild type proteins

- the sequence of the L1 protein in use for the purposes of the invention is identical to that of the L1 protein which is present in the papillomavirus when the latter is initially isolated from a benign lesion (eg condyloma acuminatum or cervical dysplasia) Indeed, it seems that at the stage of a benign lesion, the papillomavirus can always replicate freely in the state of complete virion, while in the malignant stage, the virus would have this function altered in particular due to a mutation which would have intervened at the level of the ORF coding for LL This mutation would prevent inter alia the formation of capsids
- the sequence of a protein L l of type 16 coming from a HPV isolated with starting from a condyloma is disclosed in the sequence identifier No.
- amino acid in position 202 is an amino acid other than histidine i.e. an aspartic acid or glutamic acid residue
- L2 protein this can optionally be deleted from its DNA binding site, in order to promote the elimination of any trace of DNA during the purification of the elements necessary for the implementation of the VLPs according to the invention In practice, this involves deleting or modifying one or more of the first 12 amino acids of the N-terminal end.
- L2 proteins are in particular described in WO 95/20659 and Zhou et al, J Virol (1994) 68,619

- the insertion in the sequence of the L1 or L2 protein can be carried out by preserving the entire L1 or L2 sequence or else by deleting a certain part thereof Obviously, the construction of appropriate expression cassettes (by genetic fusion) coding for these hybrid proteins will preside over the obtaining of these proteins
- the element or elements constituting the capsid can be produced in recombinant systems, bacteria, yeast, mammalian or insect cells.
- WO 95/31476 deals with the expression and the purification of a L1 protein in and from ⁇ " . coli
