Immune checkpoints are inhibitory proteins that control the strength and duration of T-cell responses. Tumor cells take advantage of these pathways to escape immune surveillance. Checkpoint inhibitors can stimulate the immune system to eliminate tumors, as shown with FDA-approved therapeutics targeting CTLA-4 and PD-1.
Characterizing both inhibitory and stimulatory molecules that control T-cell response can inform efforts to develop effective immunotherapies.
