Tissue-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 ...
متن کاملHerpes simplex virus type 1 serum neutralizing antibody titers increase during latency in rabbits latently infected with latency-associated transcript (LAT)-positive but not LAT-negative viruses.
The herpes simplex virus type 1 (HSV-1) latency-associated transcript (LAT) gene is essential for efficient spontaneous reactivation in the rabbit ocular model of HSV-1 latency and reactivation. LAT is also the only viral gene abundantly expressed during latency. Rabbits were ocularly infected with the wild-type HSV-1 strain McKrae or the McKrae-derived LAT null mutant dLAT2903. Serum neutraliz...
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 کاملThe latency associated transcripts (LAT) of herpes simplex virus: still no end in sight.
The herpes simplex virus latency associated transcripts (LAT) are the only viral gene products that accumulate to a high concentration in the trigeminal ganglia (TG) of latently infected animals. Their abundance is particularly surprising, since they are thought to be the introns of a larger, approximately 8.3 kb precursor. LAT are not linear molecules. Therefore they are either a circle or a l...
متن کاملExpression of the herpes simplex virus type 2 latency-associated transcript enhances spontaneous reactivation of genital herpes in latently infected guinea pigs
The latency-associated transcript (LAT) is the only herpes simplex virus (HSV) gene product detectable in latently infected humans and animals. In this report, we show that a 624-bp deletion in the promoter of the HSV-2 LAT had no discernable effect on viral growth in tissue culture or in acute genital infection of guinea pigs, but impaired LAT accumulation and led to a marked decrease in spont...
