Approximately 65% of the US population are infected with HSV-1 and 20% with HSV-2. Herpes simplex viruses type 1 and type 2 are significant human pathogens. The viruses persist in the body for life in the form of a latent, or silent, infection of neurons. Periodically, the viruses reactivate from latency to allow transmission to a new host, which can be associated with disease including cold sores, kerato-conjunctivitis, genital lesions and encephalitis.
The Cliffe lab investigates the mechanisms of herpes simplex virus (HSV) latency and reactivation in neurons. We use primary and differentiated neurons along with in vivo models to determine how HSV establishes a latent infection in neurons and how the virus reactivates under conditions of cell stress.
