Mutations can be introduced into the VZV-BAC-DNA plasmid by recombination between the VZV-BAC-DNA plasmid and its mutant nucleic acid. It is also possible to introduce mutations at random by using a transposon. The VZV-BAC-DNA plasmid into which the mutation has been introduced can be easily selected and amplified in E. coli. Recombinant varicella-zoster virus can be obtained by producing a virus from VZV-BAC-DNA having a mutation (Markus Wagner TRENDS in Microbilogy Vol. 10, No. 7, 2002 7 Moon). Specific examples are listed below:
- the shuttle vector and the VZV-BAC-DNA plasmid are recombined via the first homologous region, resulting in a co-insert with the shuttle vector and the VZV-BAC-DNA plasmid linked.
- the shuttle plasmid is then removed because the replication origin of the shuttle vector is temperature sensitive.

- a mutant VZV-BAC-DNA plasmid having a mutation on the shuttle vector is obtained. It is done. If the first homologous region and the second homologous region are approximately the same length, the probability that the second recombination event will occur in the second homologous region is that the second recombination event is the first homologous Probability that occurs in the region is almost the same. Therefore, about one-half of the VZV-BAC-DNA plasmid obtained has the same sequence as the one used for thread replacement, and about one-half of the plasmid has the mutation introduced into the shuttle vector. It is.
- Circular VZV BAC— Introduces mutations into DNA molecules. Specifically, a linear DNA fragment containing a selectable marker adjacent to the target sequence and a homologous sequence is introduced into E. coli capable of causing homologous recombination together with VZV-BAC-DNA. In order to avoid degradation of linear DNA in E. coli, it is necessary to use E. coli deficient in E.
- Linear DNA has regions homologous to the VZV-BAC-DNA plasmid at both ends. By producing homologous recombination through the homologous region, the desired sequence within the linear DNA fragment can be introduced into VZV-BAC DNA. When using recET or red8 j8 recombination functions, these recombination functions result in homologous recombination with homologous sequences as long as 25-50 nucleotides, which is more than recA-mediated homologous recombination. Can be used conveniently.

- gene 58 was not affected by virus growth, even if it was deleted.
- gene 56, and gene 58 especially 56 to gene 58, continuous region force knockout and insertion sites for foreign sequences (eg, gene sequences encoding BAC vector sequences and other antigens) It turned out to be a suitable gene.
- Example 1 since it was found that gene 13 is an appropriate gene for knockout and insertion of Z or foreign sequences, the multivalent gene by inserting the Mumps virus HN gene into the ORF of gene 13 The vaccine was manufactured.
- the HN gene and F gene of Mumbus virus were amplified from the Iwasaki strain, which is an epidemic strain, using PCR. Analysis of the amino acid sequences of the F gene and HN gene of the clawed Iwasaki strain showed that the F gene showed a relatively high degree of homology with field strains and vaccine strains (> 98.5%), but the HN gene was 1990. It was highly homologous to field strains in the latter half of the 1990s and low in homology with field strains and vaccine strains before the early 1990s (approximately 96%).
- a human cytomegalovirus (CMV) promoter Z enhancer sequence was operably linked upstream of the cloned gene. Plasmids using the HN gene and the F gene were named pDEST26ZMeV—HN and pDEST26ZMeV—F, respectively.
- the human cytomegalovirus promoter Z enhancer sequence has an NF- ⁇ B binding site, an AP-1 binding site, and a TATA box ( Figure 1).
- pDEST26ZMeV-F and pDEST26ZMeV-HN were transfected into 293 cells and reacted with several types of anti-MeV antibodies by the fluorescent antibody method. As a result, 293 cells transfected with pDEST2 6ZMeV-F did not react with any antibody. P DEST26ZMeV-HN transfected cells contained several anti-MeV antibodies (including antibodies with neutralizing activity). ).
- Nucleus combining this mumps virus HN gene and CMV promoter Z-enhancer A vector was prepared by linking upstream and downstream of gene 13 at both ends of the acid sequence (base number is the base number in P-Oka. In the case of the Dumas strain shown in SEQ ID NO: 4, 17037 ⁇ Corresponding to 18440 and 19347-20350;). This vector was introduced into Escherichia coli holding P—Oka strain VZV—BAC—DNA, causing homologous recombination between the vector and P—Oka strain VZV—BAC—DNA, and the ORF of gene 13 Then, the homologous thread was replaced with the linking sequence of the mumps HN gene and the CMV promoter Zenhansa (Fig. 2). The occurrence of homologous recombination was confirmed by PCR and restriction enzyme digestion.
- the BAC vector produced by homologous recombination was transfected into MRC-5 cells by electoporation.
- the plaque size of the transfected cells was the same as when the virus was used without disrupting gene 13.

- Molec ular Probes mvitrogen detection technologies Eugene, Oregon, U.S.A.
- a multivalent vaccine against both varicella-zoster virus and mumps virus could be easily produced without inhibiting the growth of the virus.
- a mutant recombinant varicella-zoster virus can be prepared, and a pathogenic weakly varicella-zoster virus strain can be obtained from the mutant virus.
- Examples of methods for preparing mutant recombinant varicella-zoster virus include mutant genes A method of preparing a mutant recombinant varicella-zoster virus by causing homologous recombination between the nucleic acid contained and the VZV-BAC-DNA plasmid. VZV-BAC
- Mutant genes used for homologous recombination with DNA plasmids may have random mutations or site-specific mutations. By using each of these, a population of mutant recombinant varicella-zoster virus having a random mutation and a mutant recombinant varicella-zoster virus having a site-specific mutation can be obtained. Hereinafter, each of them will be described in more detail.
- gene 62 into which mutations are randomly introduced is prepared using PCR.
- Mutation introduction methods using PCR are well known. For example, mutation can be introduced at random by using a thermostable polymerase that does not have a proofreading function under the condition that one of four nucleotides is small. If necessary, a marker gene such as a drug resistance gene may be linked to the mutant 62 gene.
- the mutant gene 62 prepared in this manner was introduced into E. coli along with the VZV-BAC-DNA plasmid according to the electopore polarization method. Then, the mutant sequence 62 is subjected to homologous recombination with VZV-BAC-DNA. Subsequently, the varicella-zoster virus DNA that has produced homologous recombination is isolated and introduced into Escherichia coli to obtain E. coli containing VZV-BAC DNA that has undergone homologous recombination.
- the obtained plurality of Escherichia coli contains VZV— BAC each containing gene 62 having a different mutation.
- a method for introducing a desired site-specific mutation is also well known in the art. For example, PCR is performed using a primer having a desired mutation, a gene fragment having the desired mutation is prepared, and then further PCR is performed using the mutant gene fragment. A full-length gene having a desired mutation is prepared by applying a force or an enzyme treatment such as a restriction enzyme.
- mutant gene thus prepared, a mutant recombinant varicella-zoster virus having a site-specific mutation is prepared using the procedure described in (1. 1.) above.
- SCID severe combined immunodeficiency
