T细胞的生长和功能必须受到严格调控,以便在抵御外来病原体的同时避免自身免疫和免疫缺陷。现在很明显,T细胞代谢具有高度动态性,并且对T细胞的生长、激活和分化能力有巨大影响。特定的代谢途径提供能量和生物合成前体,这些必须支持特定的细胞功能,因为效应T细胞、调节性T细胞、记忆T细胞和同种反应性T细胞在免疫和炎症中具有不同的代谢需求。在此,我们综述了控制代谢的信号通路,以及T细胞亚型的代谢表型如何与T细胞功能相结合。最终,这些代谢差异可能为调节免疫应答以及治疗炎症和自身免疫疾病提供新的机会。
T cell growth and function must be tightly regulated to provide protection against foreign pathogens while avoiding autoimmunity and immunodeficiency. It is now apparent that T cell metabolism is highly dynamic and has a tremendous impact on the ability of T cells to grow, activate and differentiate. Specific metabolic pathways provide energy and biosynthetic precursors that must support specific cell functions, as effector, regulatory, memory, and alloreactive T cells have distinct metabolic needs in immunity and inflammation. Here we review the signaling pathways that control metabolism and how the metabolic phenotypes of T cell subtypes integrate with T cell function. Ultimately, these metabolic differences may provide new opportunities to modulate the immune response and treat inflammatory and autoimmune diseases.
