γδ T cells display unique developmental, distributional, and functional patterns and can rapidly respond to various insults and contribute to diverse diseases. Different subtypes of γδ T cells are produced in the thymus prior to their migration to peripheral tissues. γδ T cells are enriched in the liver and exhibit liver-specific features. Accumulating evidence reveals that γδ T cells play important roles in liver infection, non-alcoholic fatty liver disease, autoimmune hepatitis, liver fibrosis and cirrhosis, and liver cancer and regeneration. In this study, we review the properties of hepatic γδ T cells and summarize the roles of γδ T cells in liver diseases. We believe that determining the properties and functions of γδ T cells in liver diseases enhances our understanding of the pathogenesis of liver diseases and is useful for the design of novel γδ T cell-based therapeutic regimens for liver diseases.

Fig.1  γδ T cells in liver diseases. The effector functions of hepatic γδ T cells are context-dependent, although IL-17A-producing γδ T cells predominantly localize in the liver. On the one hand, hepatic IL-17A-producing γδ T cells not only play pathogen-promoting roles in infection-induced liver injury, non-alcoholic fatty liver disease, autoimmune hepatitis, liver fibrosis/cirrhosis, and liver cancer but also promote liver regeneration (shown as →). On the other hand, hepatic IFN-γ-producing γδ T cells play protective roles in liver infection and liver cancer (shown as ⊣) and also mediate autoimmune hepatitis (shown as →). In addition, hepatic γδ T cells suppress the inflammatory response by expressing inhibitory molecules (such as CD39, shown as ⊣).
