CD8⁺记忆性T(TM)细胞的产生需要代谢重编程,其特征是线粒体脂肪酸氧化(FAO)增强。然而,为这一过程提供燃料的脂肪酸(FA)来自何处仍不清楚。我们发现,虽然CD8⁺ TM细胞的FAO水平较高,但它们从外部环境中获取的长链脂肪酸比CD8⁺效应性T(TE)细胞少得多。TM细胞并非直接利用细胞外脂肪酸,而是利用细胞外葡萄糖来支持FAO和氧化磷酸化(OXPHOS),这表明必须合成脂质以产生FAO所需的底物。我们已经证明,TM细胞依赖溶酶体水解酶LAL(溶酶体酸性脂肪酶)的细胞内源性表达来动员脂肪酸用于FAO和TM细胞的发育。我们的观察结果将LAL与淋巴细胞的代谢重编程联系起来,并表明细胞内源性脂解对TM细胞的命运起决定性作用。
Generation of CD8+ memory T (TM) cells requires metabolic reprogramming that is characterized by enhanced mitochondrial fatty acid oxidation (FAO). However, where the fatty acids (FA) that fuel this process come from remains unclear. We found that while CD8+ TM cells engaged higher levels of FAO, they acquired substantially fewer long-chain FA from their external environment than CD8+ effector T (TE) cells. Rather than using extracellular FA directly, TM cells used extracellular glucose to support FAO and oxidative phosphorylation (OXPHOS), suggesting that lipids must be synthesized to generate the substrates needed for FAO. We have demonstrated that TM cells rely on cell intrinsic expression of the lysosomal hydrolase LAL (lysosomal acid lipase) to mobilize FA for FAO and TM cell development. Our observations link LAL to metabolic reprogramming in lymphocytes and show that cell intrinsic lipolysis is deterministic for TM cell fate.
