The hepatic immune system.
The liver regulates T-cell homeostasis, induces T-cell tolerance, and supports intrahepatic T-cell responses against hepatotropic pathogens. Many data from clinical and preclinical systems provide supportive evidence for these diverse roles of the liver in modulating peripheral (systemic, mucosal, and intrahepatic) T-cell immunity. Little information is available on the cellular and molecular mechanisms that mediate the dual role of the liver in tolerizing T-cell responses and in supporting intrahepatic priming of T-cell responses. Understanding these immunoregulatory effects in the liver may offer insight into clinically relevant immunopathologies of this organ.
