Abstract:
Herpes simplex causes latent infections that periodically reactivate. Specific immunization attempts are failing to control herpes, prompting a fresh look at which host responses predominate. We report a NK complex-linked genetic locus, Rhs1, whose alleles influence the magnitude of experimental herpes simplex. Rhs1 provided rapid control of primary infection but caused a reciprocal increase in the number of latently infected neurons. Thus, in principle, establishment of latency is a consequence of efficient front line defense against herpesvirus infection. Based on conservation between human and mouse NK complexes, the data predict the presence of a human Rhs1 orthologue on chromosome 12p12-13.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
