Metabolic reprogramming in macrophages supports effector functions and differs depending on the activating stimulus. Lauterbach et al. now show that early metabolic alterations in macrophages driven by LPS signaling serve to increase the acetyl-CoA pool via citrate metabolism by the ATP-citrate lyase (ACLY), leading to histone acetylation and regulation of TLR-driven gene expression.
巨噬细胞中的代谢重编程支持效应功能,并且根据激活刺激而有所不同。 Lauterbach 等人现在表明,LPS 信号驱动的巨噬细胞中的早期代谢改变通过三磷酸腺苷-柠檬酸裂合酶 (ACLY) 的柠檬酸代谢来增加乙酰辅酶 A 池,导致组蛋白乙酰化和 TLR 驱动的基因表达调控。
