摘要
As an essential part of adaptive immunity,T cells coordinate the immune responses against pathogens and cancer cells.Lipid metabolism has emerged as a key regulator for the activation,differentiation,and effector functions of T cells.Therefore,uncovering the molecular mechanisms by which lipid metabolism dictates T cell biology is of vital importance.The tumor microenvironment is a hostile milieu,i.e.often characterized by nutrient restriction.In this environment,various cells,such as T cells and cancer cells,reprogram their metabolism,including their lipid metabolism,to meet their energy and functional needs.Here,we review the participation of fatty acid and cholesterol metabolism homeostasis in orchestrating T cell biology.We demonstrate how the tumor microenvironment reshapes the lipid metabolism in T cells.Importantly,we highlight the current cancer therapeutic interventions that target fatty acid and cholesterol metabolism of T cells.By offering a holistic understanding of how lipid metabolic adaption by T cells facilitates their immunosurveillance in the tumor microenvironment,we believe this review and the future studies might inspire the next-generation immunotherapies.
