Abstract

LAT (latency-associated transcript) is the only herpes simplex virus type 1 (HSV-1) transcript abundantly expressed during neuronal latency. LAT expression is required for the high reactivation phenotype of HSV-1 and this phenotype correlates with LAT's anti-apoptosis properties. LAT nucleotides 1 to 1499 inhibit caspase-8 (death receptor apoptotic pathway), but not caspase-9 (mitochondrial apoptotic pathway), -induced apoptosis as efficiently as larger LAT fragments. LAT sequences important for inhibiting caspase-8-induced apoptosis were also localized. The ability of LAT nucleotides 1 to 1499 to efficiently inhibit caspase-8-induced apoptosis correlates with the high reactivation phenotype of a mutant virus expressing just the first 1.5 kb of LAT (nucleotides 1 to 1499).

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
