The liver may have a role in peripheral tolerance, by serving as a site for trapping, apoptosis and phagocytosis of activated T cells. It is not known which hepatic cells are involved in these processes. It was hypothesised that liver sinusoidal endothelial cells (LSEC) which are strategically placed for participation in the regulation of sinusoidal blood flow, and express markers involved in recognition, sequestration and apoptosis, may contribute to peripheral tolerance by inducing apoptosis of activated T cells.
