Recent evidence demonstrating that exposure to rapamycin during viral infection increased the quantity and quality of antigen-specific T cells poses an intriguing paradox, since rapamycin is used in transplantation to dampen, rather than enhance, donor-reactive T cell responses. In this report, we compared the effects of rapamycin on the antigen-specific T cell response to a bacterial infection versus a transplant. Using a transgenic system in which the antigen and the responding T cell population were identical in both cases, we observed that treatment with rapamycin augmented the antigen-specific T cell response to a pathogen, while it failed to do so when the antigen was presented in the context of a transplant. These results suggest that the environment in which an antigen is presented alters the influence of rapamycin on antigen-specific T cell expansion, and highlights a fundamental difference between antigen presented by an infectious agent as compared to an allograft.
