Perforin-mediated cytotoxic T cell killing has been suggested to be of
importance in the control of noncytopathic virus infections, based on
studies with lymphocytic choriomeningitis virus (LCMV). We examined the
role of perforin in a mouse model of gammaherpesvirus infection using
transgenic perforin-deficient mice. Previous work from this laboratory has
shown that CD8 T cells are essential for the resolution of the acute lung
infection and control of latently infected B cells in murine
gamma-herpesvirus 68 infection. The absence of perforin did not
significantly affect the kinetics of either the lytic lung infection or the
latent spleen infection. Lymphocytes from both perforin-deficient and
control mice secreted comparable levels of IFN-gamma, IL-10 and IL- 6. In
addition, lymphocytes from both strains had similar levels of
CD3epsilon-dependent cytotoxic activity in the spleen, draining lymph nodes
and bronchoalveolar lavage. These data indicate that the lack of perforin
has little affect on the ability of mice to control an experimental
gammaherpesvirus infection. |
