T-cell exhaustion was originally identified during chronic infection in mice, and
was subsequently observed in humans with cancer. The exhausted T cells in the
tumor microenvironment show overexpressed inhibitory receptors, decreased
effector cytokine production and cytolytic activity, leading to the failure of
cancer elimination. Restoring exhausted T cells represents an inspiring strategy
for cancer treatment, which has yielded promising results and become a
significant breakthrough in the cancer immunotherapy. In this review, we overview
the updated understanding on the exhausted T cells in cancer and their potential
regulatory mechanisms and discuss current therapeutic interventions targeting
exhausted T cells in clinical trials.
