B.rVSV immunogenic composition
Another kind of immunogenic composition for the inventive method and compositions is vesicular stomatitis virus (VSV) delivery vector reproducible, alive, attenuation.This restructuring VSV comprises the nucleotide sequence of the selected antigen of coding, and described coded sequence is instructed its regulating and controlling sequence of expressing in mammal or vertebrate cells to regulate and control.In the method for the invention, for the antigen of DNA plasmid compositions with identical for the antigen of rVSV immunogenic composition.
VSV is a kind of bovine viral, and it is a member that is called Mononegavirales on taxonomy, comprises 11kb Nonsegmented, strand RNA genome, encode four internal structure albumen and an outside transmembrane protein.From 3 '-5 ' sequentially, the albumen of gene code is called nucleocapsid (N), phosphoprotein (P), stromatin (M), transmembrane glycoprotein (G) and polymerase (L).The VSV that uses technology known in the art separable also " rescue " to live.Referring to, as U.S. Patent number 6,044,886,6,168,943 and 5,789,299; International Publication patent No. WO99/02657; Conzelmann, 1998, Ann.Rev.Genet., 32:123-162; Roberts and Rose, 1998, Virol., 247:1-6; Lawson etc., 1995 Proc.Natl.Acad.Sci., USA 92:4477-4481.In addition, for example, the registration number that the genome sequence of VSV (Indiana) is listed in ncbi database is NC001560.Other VSV sequence, comprises VSV (Chandipura) sequence, can in this data base, obtain, for example, referring to registration number Ay382603, Af128868, V01208, V01207, V01206, M16608, M14715, M14720 and J04350 etc.VSV strain, all can obtain from preservation center such as New Jersey and Indiana etc., for example American type culture collection, Rockville, Maryland (referring to, as registration number VR-1238 and VR-1239.In the file of quoting as proof in full in this description, describe or with reference to other sequence.All documents of quoting as proof in this description are incorporated herein by reference at this.)。
Already shown that VSV genome can hold more than one exogenous gene, at least reached 3,000 bases.These viral genomes are highly stable, can not recombinate, almost rare significant sudden change.In addition,, because copying of they is that Cytoplasm copies, so their genome contains RNA, they can not be incorporated into the genome of infected host cell.Equally, these minus-stranded rna virus have relatively simple transcription regulating nucleotide sequence, can easily handle for inserting effective exogenous gene.Finally, can by change exogenous gene with respect to the position of the initial son of virus transcription to regulate the level of exogenous gene expression.3 '-5 ' gene expression gradient has reflected that the probability that can successfully cross each run into gene within gene termination/gene initial signal when transcribing varial polymerases advances along genomic templates has reduced.Therefore, be positioned at approach 3 ' exogenous gene of end transcription initiation promoter can give full expression to, those be inserted in genome more the exogenous gene of distal position express less.
VSV can copy and reach high-titer in much different cellular type, and great expression virus protein.This not only means that VSV can be used as a kind of delivery vector of effective functional exogenous gene, and approval for the production of the cell line of people's kind biological product in the corresponding accessible level of production of rVSV.
RVSV has and outstanding the crucial former exogenous gene of protective immunity of coding is delivered to the ability of many different cellular types from viral pathogen, cause subsequently real shaping immunogenic protein great expression (Haglund, K., etc., 2000 Virol., 268:112-21; Kahn, J.S. etc., 1999 Virol., 254:81-91; Roberts, A. etc., 1999 J.Virol., 73:3723-32; Rose, N.F. etc., 2000 J.Virol., 74:10903-10 and Schlereth, 2000 J.Virol., the 74:4652-7 such as B.).This immunogen of so expressing can cause the reaction of high lasting virucidin and protectiveness cytotoxic T lymphocyte (CTL) (Roberts, A. etc., 1998 J.Virol., 72:4704-11) simultaneously.
Except the effect of rVSV, the viral gene delivery carrier of this work is safe, because the disease symptoms that wild type VSV can not cause substantially in Healthy People or pathology, (Tesh as the same when a large amount of virus replication even, R.B. etc., 1969 Am.J.Epidemiol., 90:255-61).In addition, the mankind infected by it and be therefore pre-existing in the immunity of VSV be rare.If further attenuation, these rVSV compositionss are applicable to immunocompromised host or and the experimenter of subhealth state.The remarkable advantage that uses in the method VSV carrier is to exist much VSV serotype, and this is due to due to the exchange of VSV viral attachment protein G or modifying.Therefore, carry the different serotypes VSV carrier of identical heterologous antigen can repetitive administration to avoid host immune system to produce the interference of any reaction of the neutralizing antibody for VSV G albumen.
Use the technology of describing before this area can design restructuring VSV, it carries selected antigen and is inserted into the regulating and controlling sequence of any position of VSV under virus transcription promoter regulation.In one embodiment, the heterologous gene of the selected antigen of described coding is inserted between the G and L coding region of VSV.In another one embodiment, heterologous gene can merge the protein loci to G.In another embodiment, heterologous gene merges or is abutted to arbitrary other VSV gene loci.
In another embodiment, gene is in genome diverse location ' reorganization '.Particularly, by N gene ' reorganization ' in genome to diverse location.The recombinant cDNA sequence that clone produces described reorganization comprises modification initial VSV plasmid main chain (pVSV-XN1).Three variants of this initial vector comprise the plasmid that departs from normal gene order (3 '-N-P-M-G-L-5 '), as follows: i) 3 '-P-N-M-G-L-5 '; Ii) 3 '-P-M-N-G-L-5 '; And iii) 3 '-P-M-G-N-L-5 '.The method adopting for generation of the Strategies For The Cloning of these plasmids is described in Ball, and 1999 J.Virol. such as L.A., in 73:4705-12.This technology has been utilized this fact, finds that the gene end/gene initial signal between each coded sequence is almost the same, therefore allows gene rearrangement to build and replaces without importing any nucleotide.Or, some key point sudden changes can be imported to non-coding sequence to produce the restriction enzyme site that contributes to genome rearrangement nearby.
Also in another embodiment of these carriers, the amino acid whose carboxyl terminal coded sequence in 29, G gene cell matter district by the aminoacid of disappearance G gene 5 ' C-terminal by truncate.Or, lack G gene completely.In one embodiment, remove the Cytoplasm district of G gene complete.In another embodiment, remove at least 28, Cytoplasm district aminoacid.In another embodiment, approximately 20 aminoacid in disappearance Cytoplasm district.In another embodiment, approximately 10 or the aminoacid still less in disappearance Cytoplasm district.
It is reported, reorganization genome method and the protein modified method of G all can generating portion growth defect (Flanagan, E.B. wait 2001 J.Virol.75:6107-14; Schnell, M.J. etc., 1998 EMBO J., 17:1289-96).Can estimate that the such modification of VSV can produce more attenuation phenotype or even produce non-replicating VSV, can be used in the various embodiments of the present invention.Referring to, as Johnson, J.E. etc., 1998 Virol., 251:244-52.37; Johnson, J.E., etc., 1997 J.Virol., 71:5060-8.

In order to overcome the problem that any potential carrier duplicating efficiency reduces in continuous administration, designed similar one group of carrier, carry separately the G gene of different VSV serotypes, can carry out successful booster immunization inoculation.One-level aminoacid sequence from the G albumen of VSV Indiana, New Jersey and Chandipura is substantially divergent, makes the immunity that certain is pre-existing in not get rid of the infection of other kind and copy.Therefore the neutralizing antibody reaction, producing by rVSV (Indiana) should be disturbed copying of rVSV (New Jersey) or rVSV (Chandipura).Can be by using the divergent homologue from VSV Chandipura or VSV New Jersey to replace three kinds of distinct immunocompetence carriers of VSV Indiana G gene formation, to prepare the vehicle group that can allow successfully to carry out continuous immunity inoculation.
Therefore, this rVSV immunogenic composition can comprise a kind of rVSV of the single selected antigen of encoding, for expressing host.The method according to this invention, described rVSV immunogenic composition comprises a kind of rVSV, the nucleotide sequence of the identical selected antigen that it contains the more than one copy of encoding.Or said composition can comprise a kind of rVSV that expresses multiple selected antigen.Every kind of antigen can be regulated and controled by controlling element or component separately.Or every kind of antigen can be regulated and controled by identical controlling element.In another embodiment, described rVSV compositions can comprise multiple rVSV, wherein every kind of rVSV identical or different antigen of encoding.
