The vaginal murine HSV-2 infection model is very useful in studying mucosal immunity against HSV-2 (Overall et al., 1975; Renis et al., 1976; Parr and Parr, 2003). Histologically, the vagina of Depo-Provera-treated mice is lined by a single layer of mucus secreting columnar epithelial cells overlying two to three layers of proliferative cells. Even though this is morphologically different from the human vagina, it closely resembles the endocervical epithelium, which is thought to be the primary site of HSV-2 infection in women (Parr et al., 1994; Kaushic et al., 2011). In the protocol presented here, mice are pre-treated with Depo-Provera before intra-vaginal inoculation with HSV-2. The virus replicates in the mucosal epithelium from where it spreads to and replicates in the CNS including the spinal cord, brain stem, cerebrum and cerebellum. Cytokine responses can be detected in vaginal washings using ELISA or in vaginal tissues using qPCR. Further, the recruitment of leukocytes to the vagina can be determined by flow cytometry. The model is suitable for research of both innate and adaptive immunity to HSV-2 infection.
