Abstract: A mutant herpesvirus that has a mutated gene that encodes a mutant infected cell protein 0 (ICP0) can be used in therapeutic methods as well as in diagnostics and research experiments. The encoded mutant ICP0 protein can be altered in one or more regions of ICP0 that are substantially conserved between two or more herpesviruses and/or within a phosphorylation region. The mutant herpesvirus can be substantially avirulent and immunogenic.

Abstract: A mutant virus of herpes simplex virus type 1 (HSV-1) can include a mutant protein involved in replication so as to impair or inhibit replication of HSV-1. The mutant HSV-1 can have a mutation in at least one phosphorylation site of a protein involved in replication in order to inhibit phosphorylation of the site so as to prohibit or impair replication of HSV-1 and/or the clinical severity of HSV-1-mediated diseases. The mutant protein can be a mutant ICP0 that has reduced or inhibited posttranslational phosphorylation. The mutant HSV-1 and/or mutant ICP0 can be used in vaccines or other pharmaceutical preparations to treat, limit and/or prevent HSV-1 infection. The mutant HSV-1 and/or mutant ICP0 can also be used in screening and/or developing anti-HSV-1 agents.
