The Gene That Encodes the Herpes Simplex Virus Type 1 Latency-Associated Transcript Influences the Accumulation of Transcripts (Bcl-x\u3csub\u3eL\u3c/sub\u3e and Bcl-x\u3csub\u3es\u3c/sub\u3e) That Encode Apoptotic Regulatory Proteins

The herpes simplex virus type 1 latency-associated transcript (LAT) inhibits apoptosis. We demonstrate here that LAT influences the accumulation of the Bcl-xL transcript versus the Bcl-xS transcript in Neuro-2A cells. Bcl-xL encodes an antiapoptotic protein, whereas Bcl-xS encodes a proapoptotic protein. Promoting the accumulation of Bcl-xL in neurons may inhibit apoptosis, thus enhancing the latency-reactivation cycle
