Interactions between the liver and CD8+ T cells can lead to tolerance, due in part to CD8+ T cell death. To test whether this was the case in an extrahepatic infection, we investigated the fate and effector capacity of intrahepatic CD8+ T cells during lung-restricted influenza infection in mice. Virus-specific T cells accumulated in livers without detectable intrahepatic presentation of viral Ags, and this accumulation was not restricted to the contraction phase, but was apparent as early as day 5. Intrahepatic influenza-specific cells were functionally similar to those recovered from the bronchioalveolar lavage, based on ex vivo cytokine production and specific target lysis. Both adoptive transfer of liver lymphocytes and orthotopic liver transplant of organs containing accumulated effector T cells revealed that activated CD8s from the liver were viable, expanded during reinfection, and generated a memory population that trafficked to lymphoid organs. Thus, intrahepatic CD8+ T cells re-enter circulation and generate functional memory, indicating that the liver does not uniformly incapacitate activated CD8+ T cells. Instead, it constitutes a substantial reservoir of usable Ag-specific effector CD8+ T cells involved in both acute and recall immune responses.
