HHV LAT
HHV Latency Associated Transcript (HHV LAT) is a length of RNA which accumulates in cells hosting long-term, or ''latent'', Human Herpes Virus (HHV) infections. The LAT RNA is produced by genetic transcription from a certain region of the viral DNA. LAT regulates the viral genome and interferes with the normal activities of the infected host cell. Herpes virus may establish lifelong infection during which a ''reservoir'' virus population survives in host nerve cells for long periods of time. Such long-term Herpes infection requires a mode of cellular infection known as ''latent'' infection. During the latent infection, the metabolism of the host cell is disrupted. While the infected cell would ordinarily undergo an organized death or be removed by the immune system, the consequences of LAT production interfere with these normal processes. Latency is distinguished from ''lytic'' infection; in lytic infection many Herpes virus particles are produced and then burst or ''lyse' ...

Herpesviridae
''Herpesviridae'' is a large family of DNA viruses that cause infections and certain diseases in animals, including humans. The members of this family are also known as herpesviruses. The family name is derived from the Greek word ''ἕρπειν'' ( 'to creep'), referring to spreading cutaneous lesions, usually involving blisters, seen in flares of herpes simplex 1, herpes simplex 2 and herpes zoster ( shingles). In 1971, the International Committee on the Taxonomy of Viruses (ICTV) established ''Herpesvirus'' as a genus with 23 viruses among four groups. As of 2020, 115 species are recognized, all but one of which are in one of the three subfamilies. Herpesviruses can cause both latent and lytic infections. Nine herpesvirus types are known to primarily infect humans, at least five of which – herpes simplex viruses 1 and 2 (HSV-1 and HSV-2, also known as HHV-1 and HHV-2; both of which can cause orolabial herpes and genital herpes), varicella zoster virus (or HHV-3; the cause ...
