Herpes simplex virus thymidine kinase and specific stages of latency in murine trigeminal ganglia

From marker rescue, sequencing, transcript, and latency analyses of the thymidine kinase-negative herpes simplex virus mutant dlsactk and studies using the thymidine kinase inhibitor Ro 31-5140, we infer that the virus-encoded thymidine kinase is required in murine trigeminal ganglia for acute replication and lytic gene expression, for increasing the numbers of cells expressing latency-associated transcripts, and for reactivation from latent infection.
