Abstract
The electron transport chain (ETC) couples electron transfer with proton pumping to generate ATP and it also regulates particular innate and adaptive immune cell function. While NLRP3 inflammasome activation was initially linked to reactive oxygen species (ROS) produced from Complexes I and III, recent research suggests that an intact ETC fueling ATP is needed. Complex II may be responsible for Th1 cell proliferation and in some cases, effector cytokine production. Complex III is required for regulatory T (Treg) cell function, while oxidative phosphorylation (OXPHOS) and Complexes I, IV, and V sustain proliferation and antibody production in B lymphocytes, with OXPHOS also being required for B regulatory (Breg) cell function. Despite challenges, the ETC shows therapeutic targeting potential for immune-related diseases and in immuno-oncology.
电子传递链(ETC)将电子传递与质子泵结合起来以产生 ATP,它还能调节特定的先天性和适应性免疫细胞功能。虽然 NLRP3 炎症小体的激活最初与复合体 I 和 III 产生的活性氧(ROS)有关,但最近的研究表明,需要有一个完整的 ETC 为 ATP 提供燃料。复合体 II 可能负责 Th1 细胞的增殖,在某些情况下还负责效应细胞因子的产生。调节性 T(Treg)细胞的功能需要复合体 III,而氧化磷酸化(OXPHOS)和复合体 I、IV 和 V 可维持 B 淋巴细胞的增殖和抗体生成,B 调节性(Breg)细胞的功能也需要 OXPHOS。尽管存在挑战,但 ETC 显示出了针对免疫相关疾病和免疫肿瘤学的治疗潜力。
