以最小的损害抵御病原体的能力决定了免疫系统的鲁棒性。多种因素,包括病原体加工、鉴定、介体和效应分子的分泌以及免疫细胞增殖和分化成各种亚群,构成了建立有效免疫应答的成功。细胞代谢控制着所有这些复杂的过程。细胞利用不同的燃料来源,并根据其能量需求在不同的代谢途径之间来回切换。免疫细胞依赖于满足其能量需求的三个最关键的代谢途径是氧化代谢、糖酵解和β-氨基糖苷分解。这些代谢途径之间的动态切换对于免疫细胞的最佳功能是必要的。此外,这些代谢途径之间的转换需要严格调节,以达到最佳效果。免疫细胞的生长、增殖、分泌和效应子功能依赖于瓦尔堡效应。在这里,我们假设sirtuin,SIRT 6,可能是一个负调节的瓦尔堡效应。我们还假设SIRT 6可以通过调节关键信号通路作为免疫细胞代谢和功能的主要调节剂。
The ability to ward off pathogens with minimal damage to the host determines the immune system's robustness. Multiple factors, including pathogen processing, identification, secretion of mediator and effector molecules, and immune cell proliferation and differentiation into various subsets, constitute the success of mounting an effective immune response. Cellular metabolism controls all of these intricate processes. Cells utilize diverse fuel sources and switch back and forth between different metabolic pathways depending on their energy needs. The three most critical metabolic pathways on which immune cells depend to meet their energy needs are oxidative metabolism, glycolysis, and glutaminolysis. Dynamic switching between these metabolic pathways is needed for optimal function of the immune cells. Moreover, switching between these metabolic pathways needs to be tightly regulated to achieve the best results. Immune cells depend on the Warburg effect for their growth, proliferation, secretory, and effector functions. Here, we hypothesize that the sirtuin, SIRT6, could be a negative regulator of the Warburg effect. We also postulate that SIRT6 could act as a master regulator of immune cell metabolism and function by regulating critical signaling pathways.
