γHV68 is a natural pathogen that is a well-established and widely-used murine model of EBV infection that shares an array of characteristics with human EBV infection, including latent persistence in B cells, viral reactivation from latency, a potent CD8 T cell response, and immune evasion tactics (Olivadoti et al., 2007; Wirtz et al., 2016). The gene discussed is CD8A; the disease is Epstein-Barr virus infection.
