Macacine gammaherpesvirus 4 (McHV-4), commonly known as rhesus lymphocryptovirus (RLV), is a species of virus in the genus Lymphocryptovirus, subfamily Gammaherpesvirinae, family Herpesviridae, and order Herpesvirales.[1][2]
In nature, RLV infects rhesus macaques (Macaca mulatta).
Comparison with Epstein-Barr virus
[edit]Its genetic structure has been fully sequenced and found to be highly homologous with that of Epstein-Barr virus (EBV), at 65%. The structural proteins are highly conserved, while genes expressed during Human gammaherpesvirus 4 latent infection are much less well conserved. Even in cases where genes have low homology, the RLV infection genes are functionally interchangeable with EBV genes.[3]
RLV infection in rhesus monkeys resembles EBV infection in humans in several respects:
- Oral transmission,
- Atypical lymphocytosis
- Lymphadenopathy
- Activation of CD23+ peripheral blood B cells
- Sustained serologic responses to lytic and latent Human gammaherpesvirus 4 antigens
- Latent infection in the peripheral blood
- Virus persistence in oropharyngeal secretions
These features make the rhesus lymphocryptovirus potentially useful for studying the pathogenesis, prevention, and treatment of EBV infection and associated oncogenesis.[4]
