Abstract Short persistence and early exhaustion of T cells are major limits to the efficacy and broad application of immunotherapy.Exhausted T and chimeric antigen receptor (CAR)-T cells upregulate expression of genes associated with terminated T cell differentiation, aerobic glycolysis and apoptosis.Among cell exhaustion characteristics, impaired mitochondrial function and Foot Massagers dynamics are considered hallmarks.Here, we review the mitochondrial characteristics of exhausted T cells and particularly discuss different aspects of mitochondrial metabolism and plasticity.
Furthermore, we propose a novel strategy of rewiring mitochondrial metabolism to emancipate T cells from exhaustion and of targeting mitochondrial plasticity to boost Collections CAR-T cell therapy efficacy.
