The latency-associated transcript gene of herpes simplex virus type 1 (HSV-1) is required for efficient in vivo spontaneous reactivation of HSV-1 from latency

Abstract excerpt

During herpes simplex virus type 1 (HSV-1) neuronal latency, the only viral RNA detected is from the latency-associated transcript (LAT) gene. We have made a LAT deletion mutant of McKrae, an HSV-1 strain with a very high in vivo spontaneous reactivation rate. This mutant (dLAT2903) lacks the LAT promoter and the first 1.6 kb of the 5' end of LAT. dLAT2903 was compared with its parental virus and with a rescued...
