Ross River virus (RRV), chikungunya virus (CHIKV), and related alphaviruses cause debilitating polyarthralgia and myalgia. Mouse models of RRV and CHIKV have demonstrated a role for the adaptive immune response in the control of these infections. However, questions remain regarding the role for T cells in viral control, including the magnitude, location, and dynamics of CD8+ T cell responses. To address these questions, we generated a recombinant RRV expressing the H-2b-restricted gp33 determinant derived from the glycoprotein (gp) of lymphocytic choriomeningitis virus (LCMV) (“RRV-LCMV”). Utilizing tetramers, we tracked gp33-specific CD8+ T cells during RRV-LCMV infection. We found that acute RRV infection induces activation of CD8+ T cell responses in lymphoid and musculoskeletal tissues that peak from 10 to 14 days post-inoculation (dpi), suggesting that CD8+ T cells contribute to control of acute RRV infection. Mice genetically deficient for CD8+ T cells or wild-type mice depleted of CD8+ T cells had elevated RRV loads in skeletal muscle tissue, but not joint-associated tissues, at 14 dpi, suggesting that the ability of CD8+ T cells to control RRV infection is tissue-dependent. Finally, adoptively transferred T cells were capable of reducing RRV loads in skeletal muscle tissue of Rag1−/− mice, indicating that T cells can contribute to the control of RRV infection in the absence of B cells and antibody. Collectively, these data demonstrate a role for T cells in the control of RRV infection and suggest that the antiviral capacity of T cells is controlled in a tissue-specific manner.
