The metabolic profile of activated, effector and memory T cells. CD8+ Tmem cell and Treg cell rely on FAO and OXPHOS for survival and to support function. In addition, Tmem cells acquire glycerol by AQP9 for triglyceride synthesis and then promote Tmem cell proliferation and survival (left panel). In right panel, activated effector T cells (Effect T cells, CD8+Teff cell and CD4+Th cells) use aerobic glycolysis and FAS for proliferation. In activated effector T cell, most pyruvate become lactate and minority of pyruvate enters TCA cycle. However, PPP yields both nucleotide and NADPH for FAS. Glutaminolysis is also important for supplement of TCA cycle intermediates for biosynthesis
