Abstract

The malate shuttle is known to maintain the balance of NAD+/NADH between the cytosol and mitochondria. However, in Tex cells, it primarily detoxifies ammonia (via GOT1-mediated production of 2-KG in an atypical reaction) and provides longevity to chronic-infection-induced Tex cells against ammonia-induced cell death.

氧化还原和排毒:苹果酸穿梭代谢保持疲惫的T细胞健康。
苹果酸穿梭被认为可以维持细胞质和线粒体之间NAD+/NADH的平衡。然而,在特克斯细胞中,它主要解毒氨(通过got1介导的非典型反应产生2-KG),并延长慢性感染诱导的特克斯细胞的寿命,使其免受氨诱导的细胞死亡。
