Immune cell plasticity has extensive implications in the pathogenesis and resolution of metabolic disorders, cancers, autoimmune diseases and chronic inflammatory disorders. Over the past decade, nutritional status has been discovered to influence the immune response. In metabolic disorders such as obesity, immune cells interact with various classes of lipids, which are capable of controlling the plasticity of macrophages and T lymphocytes. The purpose of this review is to discuss lipids and their impact on innate and adaptive immune responses, focusing on two areas: (1) the impact of altering lipid metabolism on immune cell activation, differentiation and function and (2) the mechanism by which lipids such as cholesterol and fatty acids regulate immune cell plasticity.
免疫细胞可塑性在代谢紊乱、癌症、自身免疫性疾病和慢性炎症性疾病的发病机制及转归中具有广泛影响。在过去十年中,人们发现营养状况会影响免疫反应。在肥胖等代谢紊乱中,免疫细胞与各类脂质相互作用,这些脂质能够控制巨噬细胞和T淋巴细胞的可塑性。本综述的目的是讨论脂质及其对固有免疫和适应性免疫反应的影响,重点关注两个方面:(1)脂质代谢改变对免疫细胞激活、分化和功能的影响;(2)胆固醇和脂肪酸等脂质调节免疫细胞可塑性的机制。
