CD8+ T cells undergo major metabolic changes upon activation, but how metabolism influences the establishment of long-lived memory T (TM) cells after infection remains a key question. We have shown here that CD8+ TM cells, but not effector CD8+ (TE) cells, possessed substantial mitochondrial spare respiratory capacity (SRC). SRC is the extra capacity available in cells to produce energy in response to increased stress or work and as such is associated with cellular survival. We found that interleukin-15 (IL-15), a cytokine critical for CD8+ TM cells, regulated SRC and oxidative metabolism by promoting mitochondrial biogenesis and expression of carnitine palmitoyl transferase (CPT1a), a metabolic enzyme that controls the rate-limiting step to mitochondrial fatty acid oxidation (FAO). These results show how cytokines control the bioenergetic stability of TM cells after infection by regulating mitochondrial metabolism.
