控制CD8+ T细胞的转录和代谢程序由多种丝氨酸/苏氨酸激酶网络调节。人们一直认为AKT激酶和哺乳动物雷帕霉素靶蛋白(mTOR)控制着T细胞的代谢。在这里,我们挑战这一范式,并讨论了这些激酶在CD8+ T细胞中的另一种作用,即控制细胞迁移。另一个新兴的概念是amp活化蛋白激酶(AMPK)家族成员控制T细胞代谢并决定CD8+ T细胞的效应与记忆命运。我们推测代谢和免疫记忆之间的一个联系是由于激酶获得了控制T细胞代谢的能力,从而控制了调节CD8+ T细胞效应功能和迁移能力的关键转录因子的表达。
The transcriptional and metabolic programs that control CD8+ T cells are regulated by a diverse network of serine/threonine kinases. The view has been that the kinases AKT and mammalian target of rapamycin (mTOR) control T cell metabolism. Here, we challenge this paradigm and discuss an alternative role for these kinases in CD8+ T cells, namely to control cell migration. Another emerging concept is that AMP-activated protein kinase (AMPK) family members control T cell metabolism and determine the effector versus memory fate of CD8+ T cells. We speculate that one link between metabolism and immunological memory is due to the acquired ability of kinases that evolved to control T cell metabolism to control the expression of key transcription factors that regulate CD8+ T cell effector function and migratory capacity.
