Figure 3. Immune checkpoint blockade may regulate metabolic reprogramming of T cells.
Blockade of PD-1 and CTLA4 may increase the metabolic fitness of Teff by enhancing the activity of PI3K/Akt/mTor and increasing cMyc expression that then stimulate aerobic glycolysis and anabolic metabolism. AA, amino acids; FA, fatty acids; Costim, costimulation.
