Popis: Murine models of gamma interferon (IFN-γ) deficiency demonstrate the role of this cytokine in attenuating acute herpes simplex virus (HSV) disease; however, the effect of IFN-γ on the establishment and maintenance of neuronal latency and viral reactivation is not known. Using the IFN-γ knockout (GKO) model of IFN-γ deficiency and sensitive quantitative PCR methods, we show that IFN-γ significantly reduces the ganglion content of latent HSV-1 in BALB/c mice, which in turn delays viral time to reactivation following UV irradiation. Similar effects were not seen in the C57BL/6 strain. These results indicate that IFN-γ significantly attenuates latent HSV infection in the mouse model of ocular infection but has no impact on the maintenance of latency or virus reactivation.
