Core Tip
Core tip: The liver is particularly enriched in unconventional T cells expressing the gamma-delta T cell receptor and the functional role of these gamma-delta (γδ) T cells in liver diseases is being intensively investigated at present. γδ T cells accumulate in inflamed liver and their function appears highly dependent on the distinct subsets. In principle, γδ T cells can be protective as well as pathogenic in the context of liver inflammation. This review summarizes the current knowledge of γδ T cell effector functions and the cytokines produced by these cells in human liver diseases and murine experimental models of acute and chronic liver injury.
