Abstract

Metabolic reprogramming of T lymphocytes has a decisive role in their activation, differentiation, and functional fate commitment. Metabolic reprogramming guides not only the generation of T effector and T memory cells but also the development of dysfunctional exhausted (T EX ) cells. A recent study by Haku et al published in Nature Immunology provides new insights into the role of mitochondria in regulating the metabolic capabilities of T EX cells and their implications for antitumor immunity.
