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.
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 a...
متن کاملHerpes Simplex Virus Type 1 Latency-Associated Transcript Reduces Human Neuroblastoma Cell Proliferation
Background and Aims: The latency-associated transcript (LAT) transcribed by latent Herpes Simplex Virus type-1 in neuron cells are able to influence their host cell pathways. While the most of previous studies were focused on anti-apoptotic effects of LAT, our investigation is making an effort to explore LAT potency on cell cycle pathway in neuroblastoma cell lines. Methods: The evaluation of L...
متن کاملA 348-base-pair region in the latency-associated transcript facilitates herpes simplex virus type 1 reactivation.
Latency-associated transcript (LAT) promoter deletion mutants of herpes simplex virus type 1 have a reduced capacity to reactivate following adrenergic induction in the rabbit eye model. We have mapped a reactivation phenotype within LAT and describe the construction of recombinants in which poly(A) addition sites have been placed at intervals within the LAT region to form truncated LAT transcr...
متن کاملMouse model of Bell's palsy induced by reactivation of herpes simplex virus type 1.
In order to investigate the mechanism of Bell's palsy, we developed an animal model of facial nerve paralysis induced by the reactivation of herpes simplex virus type 1 (HSV-1). Eight weeks after recovery from facial nerve paralysis caused by inoculation with HSV-1, the mice were treated with auricular skin scratch at the site of the previous inoculation, or with intraperitoneal injection of an...
متن کاملTissue-specific splicing of the herpes simplex virus type 1 latency-associated transcript (LAT) intron in LAT transgenic mice.
To study the regulation of herpes simplex virus type 1 (HSV-1) latency-associated transcript (LAT) expression and processing in the absence of other cis and trans viral functions, a transgenic mouse containing the region encompassing the LAT promoter (LAP1) and the LAT 5' exon through the 2.0-kb intron was created. LAT expression was detectable by reverse transcriptase PCR (RT-PCR) in a number ...
