Definitions
- the present invention relates to a vector which is suitable for activating the immune system against cells associated with papilloma viruses or sequences thereof, a vaccination agent containing such a vector and the use of both.
- HPVs Human papilloma viruses
- benign e.g. Warts
- malignancies e.g. B. Carcinomas of the skin and uterus, epithelial neoplasms.
- HPVs are also being considered for the development of malignant tumors of the respiratory tract.
- HPVs are also considered to be at least jointly responsible for the development of squamous carcinomas of the lungs.
- Papilloma viruses have an icosahedral capsid without a shell, in which a circular, double-stranded DNA molecule of approximately 7900 bp is present.
- the capsid comprises a major capsid protein (L1) and a minor capsid protein (L2).
- L1 open reading frame
- L2-ORF open reading frame
- L1 or L1 and L2 lead to the formation of virus-like particles (VLPs) in vitro.
- VLPs virus-like particles
- E6 and E7 are encoded by E6-ORF or E7-ORF.
- the present invention is therefore based on the object of providing a means by which the immune system can be activated to recognize and switch off cells, in particular tumor cells, which are associated with papilloma viruses or sequences thereof. According to the invention, this is achieved by the subject matter in the claims.
- the present invention thus relates to a vector with a nucleic acid coding for a fusion polypeptide, the fusion polypeptide comprising a structural papillomavirus (poly) peptide and a non-transforming (poly) peptide encoded by an early papillomavirus gene.
- vector includes any vector that is suitable for gene transfer, i.e. the introduction of nucleic acids into cells.
- the vector can be used in the
- the vector can be a plasmid or a virus vector.
- a virus vector examples include retroviral, adenovirus, vaccinia virus or adeno-associated virus (AAV) vectors, the latter being preferred.
- An AAV vector can be in wild-type or modified form. It can also only include those sequences, such as ITR sequences, that are necessary for its transduction capability. However, it can also be favorable if it additionally comprises sequences such as rep sequences which enable it to be integrated into chromosome 19.
- a virus vector can be present as a virus particle or in the form of its nucleic acid. It is preferred if the virus vector is replication-defective.
- papilloma virus encompasses any papilloma virus or sequences thereof which can be associated with cells, in particular tumor cells.
- it can be HPVs and very particularly "high risk” HPVs, such as HPV16, 1 8, 33, 35 and 45.
- nucleic acid encompasses any nucleic acid, such as DNA and / or RNA, that encodes a fusion polypeptide that includes a papillomavirus (poly) structural peptide and a non-transforming (poly) early papillomavirus gene-encoded peptide. It is favorable if the nucleic acid can be expressed. It is particularly favorable if they are under the control of a constitutive or inducible promoter, such as a tissue or tumor-specific one Promoter stands.
- a constitutive or inducible promoter such as a tissue or tumor-specific one Promoter stands.
- structural papillomavirus (poly) peptide encompasses any peptide or polypeptide of a papillomavirus which is at least partly responsible for the structure of the papillomavirus.
- a (poly) peptide is encoded by L1-ORF or L2-ORF of a papilloma virus or by a part thereof.
- a (poly) peptide which can be present as a VLP is particularly preferred.
- a non-transforming (poly) peptide encoded by an early papillomavirus gene encompasses any peptide or polypeptide which is encoded by an early papillomviurs gene, in particular E1, E2, E4, E5, E6 or E7-ORF or by a part of it is coded and non-transforming.
- non-transforming indicates that the (poly) peptide has no transformability by nature or by intervention.
- a preferred (poly) peptide is by E6 or E7 ORF of a papilloma virus or by
- fusion polypeptide indicates that the papillomvirs (poly) structural peptide and the non-transforming (early) papillomavirus gene encoded (poly) peptide may be present in any combination in the fusion polypeptide.
- the individual (poly) peptides can also come from different papilloma viruses.
- the C-terminus of the structural (poly) peptide is connected to the N-terminus of the non-transforming (poly) peptide. It may also be advantageous if the non-transforming (poly) peptide is located within the structural (poly) peptide.
- a preferred fusion polypeptide comprises a (poly) peptide encoded by HPV 16 L1 -ORF and a (poly) peptide encoded by HPV1 6 E6 or E7-ORF. Furthermore, a fusion polypeptide is preferred which comprises a (poly) peptide encoded by HPV 18 L1 ORF and a (poly) peptide encoded by HPV 18 E6 or E7 ORF.
- an AAV vector can be produced as a virus particle as follows: The 5 'end of the HPV 16 E6 ORF is ligated to the 3' end of the HPV 16 L1 ORF. Previously, part of the E6 ORF was deleted, which destroyed the transforming properties of E6. The DNA fragment L1 -ORF-E6-ORF is inserted into an AAV vector which contains the 5'- and 3'-ITR-
- AAV vector Contains sequences of AAV, but not the sequences coding for the AAV rep and cap proteins. The insertion takes place between the two ITR sequences.
- the DNA fragment L1 -ORF-E6-ORF is under the control of a promoter which is heterologous with respect to AAV.
- the resulting AAV vector is transfected into cells that express the AAV Rep and Cap proteins.
- the cells are further infected with a helper virus, e.g. Adenovirus, whereby the AAV vector is obtained as a virus particle.
- helper virus e.g. Adenovirus
- the immune system can be activated to recognize and switch off cells, in particular tumor cells, which are associated with papilloma viruses or sequences thereof. This can be achieved prophylactically and in therapy.
- cells of the organism in question such as antigen-presenting cells, for example dendritic cells, B cells, macrophages and / or tumor cells or pre-tumor cells associated with papilloma viruses or sequences thereof, are transduced with the vector.
- the transduction can be carried out by conventional methods. If the vector is in the form of a virus particle, it is favorable to infect the cells with it. On the other hand, if it is present as nucleic acid, such as DNA, it is advisable to transfect the cells with it.
- Electroporation, lipofection and particle cannon are examples of transfection techniques.
- the cells can be present in the organism.
- the cells to be transduced can also be isolated from the organism, transduced outside the organism and then returned to the organism. Such cells are called autologous cells.
- allogeneic cells can also be used for transduction with regard to the organism. It is advantageous if these cells belong to an HLA type corresponding to the organism. Those skilled in the art are familiar with methods of imparting a certain HLA type to cells. It is also beneficial if in one of the above methods, the tumor cells or pre-tumor cells are inactivated before they are returned to the organism. Conventional methods such as radiation can be carried out for this.
- Another object of the present invention is a vaccination agent which comprises a vector above and conventional auxiliary substances such as buffers, diluents, carriers, etc. It may be beneficial if the vaccination agent contains other substances that affect the immune system, e.g. against tumor cells. Such substances can in particular be MHC-1 molecules, costimulatory molecules, e.g. B7, and secretory immunostimulators, e.g. Cytokines such as IL-2, IL-1 2, interferon and GM-CSF.
- the substances can e.g. in the form of peptides, in particular synthetic peptides.
- the substances can also be in the form of expression plasmids encoding them, which can also encode HLA molecules. It is particularly favorable if the vaccination agent also by the
- the present invention it is possible to activate the immune system against cells which are associated with papilloma viruses or sequences thereof. These cells can be tumor cells or pre-tumor cells.
- the immune system can be activated prophylactically and in therapy.
- the present invention represents a new step in treating the most serious diseases using in vivo or ex vivo gene therapy.
- the invention is illustrated by the following example.
- L1 ORF From a genomic HPV1 6 clone (see Kirnbauer et al, (1 993), 6929-6936) the L1 ORF was amplified by a PCR reaction. For this purpose, L1-specific primers were used which have an additional Bgl II restriction site at the 5 'end. The amplified DNA fragment was digested with Bgl II and inserted into the BamHI restriction site of the usual vector pUC 19. An EcoRV- was identified at position 7051 of L1 -ORF by specific mutagenesis
- Vector pVL1 392 inserted. From this, the L1-E7 fusion gene was cut out by NotI / Smal and inserted into the NotI restriction site of the AAV vector pUF2 (cf. Zolotukhin et al., J. Virol. 70, (1 996), 4646-4654). A vector was obtained which codes for an HPV16 L1 -E7 fusion polypeptide. Viral particles of the vector were obtained in accordance with customary methods (cf.
