Outline of Final Research Achievements |
In our previous study, the amino acid substitution of H from Q at the 125th position of viral thymidine kinase (vTK) gene amplified from the central spinal fluid (CSF) of neonatal HSV-1 infection was confirmed to confer acyclovir (ACV)-resistance. In this study, recombinant HSV-1 with the mutation in vTK gene was generated artificially by using BAC system. The recombinant HSV-1 showed ACV-resistance in vitro, but maintained neurovirulence in mouse infection model. The sensitivity of ACV-resistant HSV-1 to ACV was confirmed to be associated significantly with the neurovirulence in mouse infection model, being that the higher the resistance, lower the neurovirulence in mice. The present study indicates that virological test of and selection of proper treatment for the patients, who showed intractable HSV-1 disease against ACV-therapy, are required,
