摘要:
It is intended to provide a promoter for inducing expression selectively and strongly in an immunocompetent cell and/or a blood cell such as a lymphocyte. In the invention, the object was achieved by finding that HHV6 MIE promoter, HHV7 MIE promoter and HHV7 U95 promoter unexpectedly induce a specific expression in an immunocompetent cell and/or a blood cell such as a T lymphocyte. By utilizing the promoters, a selective delivery of a DNA vaccine or the like can be realized.

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.

摘要:
Disclosed is a method for exact identification of the attenuated varicella virus Oka strain or a strain derived therefrom capable of functioning as an attenuated varicella live vaccine virus, which comprises analyzing the difference in the genomic DNA and fragments thereof between the Oka strain and a sample varicella strain, and determining whether or not a sample strain satisfies all of the following eight characteristics: the sizes of the HpaI-K fragment and the EcoRI-P fragment; the size of R2-487 region of Gene14 and the analysis by PCR-SSCP; the sizes of the restriction fragments obtained by digesting the R2-1764 fragment with AccIII; the absence or presence of a PstI cleavage site; the homology of the amino acid sequences coded by R2-487 coding region; and the homology of the amino acid sequences coded by the coding region of VZV Gene14. The method of the present invention is extremely useful for the quality control and quality assurance of attenuated varicella live vaccines. Also disclosed are an isolated virus strain which is substantially the same virus strain as identified by the above method; an attenuated varicella virus live vaccine comprising the same virus strain as identified by the above method; an attenuated varicella virus Oka strain antigen; and a pair of primers which are advantageously, effectively usable in the above method.
