Abstract
A mutant HSV-1 (referred to herein as KOS-NA) was generated. KOS-NA contains novel mutations in the UL39 gene, which encodes for a protein that is a large subunit of ribonucleotide reductase (i.e., ICP6). These UL39 mutations were found to alter two amino acids in ICP6 (R950H and L393P) and are responsible for attenuation of KOS-NA in vivo, and resulted in diminished ICP6 protein levels. These novel UL39 mutations regulate the expression and/or stability of ICP6 and severely impact HSV-1 pathogenesis. Mutant HSV viruses containing these mutations appear to protect against HSV infection and can serve as therapeutic vaccines to help combat preexisting HSV infection in infected individuals.
