Abstract:
The problems to be solved by the present invention are to provide: a recombinant varicella-zoster virus; a process for producing the same; a pharmacological composition containing a recombinant varicella-zoster virus; a vector containing a BAC vector sequence in the specific gene of a genomic gene of varicella-zoster virus; cells containing such a vector; a fragment capable of homologous recombination with a genome of varicella-zoster virus; a nucleic acid cassette containing the BAC vector sequence; and a multivalent vaccine. The above problems were solved by developing a process for producing a recombinant varicella-zoster virus, wherein the BAC vector sequence is inserted into a specific virus gene.
Abstract:
A nucleic acid molecule containing nucleotide sequences that encode the capsid protein, pre-membrane protein and non-structural protein of Japanese encephalitis virus, and a nucleotide sequence that encodes the envelop protein of a second flavivirus, wherein the nucleotide sequence(s) that encode(s) the pre-membrane protein and/or non-structural protein of Japanese encephalitis virus contain(s) nucleotide mutations that produce one or more amino acid mutations that attenuate the virus.
Abstract:
The present invention provides a vaccine composition for transnasal mucous membrane administration, which contains an influenza virus antigen, polyriboinosinic polyribocytidylic acid (poly (I:C)) or a derivative thereof and a carboxyvinyl polymer. The present invention also provides a prophylactic method of influenza, including a step of administering the vaccine composition at least once to the nasal mucosa of a subject in need thereof.
Abstract:
The present invention provides an adjuvant for cancer antigen peptide vaccines and virus antigen peptides, containing a pertussis vaccine as a primary ingredient. The present invention also provides a therapeutic agent for a cancer or viral infectious disease, and a prophylactic agent for metastasis or recurrence of cancer or onset of virus-induced tumor, containing a cancer antigen peptide or virus antigen peptide and a pertussis vaccine. A pertussis vaccine that can be suitably used is a whole cell body pertussis vaccine. The agents of the present invention can be safely administered in a plurality of doses.
Abstract:
Mutant measles virus antigens containing at least one protein antigen selected from the group consisting of (I) mutant measles virus H protein antigens and (II) mutant measles virus F protein antigens as specified below: (I) at least one measles virus H protein selected from the group consisting of a full-length protein of an amino acid sequence consisting of 617 amino acids in total described in SEQ ID NO.2 or 10 and specified peptide fragments thereof, and (II) at least one measles virus F protein antigen selected from the group consisting of a full-length protein of an amino acid sequence consisting of 550 amino acids in total described in SEQ ID NO:18 or 20 specified peptide fragment thereof; and mutant measles virus genes containing genes encoding the above measles virus antigens. The use of these antigens or genes encoding the same makes it possible to efficiently and economically provide attenuated live measles vaccines or gene vaccines suitable for epidemic measles virus stains and diagnostics for appropriately detecting the infection with epidemic measles virus stains.

Abstract:
Disclosed are isolated non-A, non-B hepatitis virus genomic cDNA fragments of the entire region of the virus gene nucleotide sequence from the 1st to 9416th nucleotides shown in Fig. 2(1) through Fig. 2(16) hereof. The fragments are in particular a cDNA covering the sequence from the 333rd to the 422nd nucleotide, the coding region from the 333rd to 9362nd nucleotides. The cDNA fragments and antigen polypeptide expression products thereof are useful as a diagnostic reagent for non-A, non-B hepatitis. The antigen polypeptide is also useful as an active ingredient for a non-A, non-B hepatitis virus vaccine.
Abstract:
Three kinds of core protein coded for with a gag gene and three kinds of enzyme coded for with a pol gene are each separately mass-produced as a mature or active protein by inserting cDNA fragments containing at least protease genes among retrovirus genes into mass-expressed genes and directly gene expressing vectors to prepare a plasmid, expressing retrovirus genes therewith, and processing the product of expression per se with a protease present in said product. Alternatively, cDNA fragments containing a nef gene domain of HIV is inserted into mass-expressed genes and directely gene expressing vectors to prepare a plasmid, with which a Nef protein is mass-produced as the product of expression of a nef gene.
Abstract:
The present invention provides a method of preparing a plasmid having both expressing ability of retroviral genes and after-translational processing, and the resultant plasmid and the expression products thereof. The method of the present invention is to prepare a plasmid by insertion-linking a cDNA fragment containing at least protease gene from among retroviral genes with a highly expressing gene or a gene direct expressing vector, thereby causing expression of the retroviral genes, and at the same time, to process said expression product itself with protease in that expression product, thereby mass-producing three kinds of core protein encoded by gag gene, and three kinds of enzyme encoded by pol gene, in the form of individual single mature or active protein.
