Although human cancer is often surrounded by immune cells, only a small number are tumor-reactive T cells that recognize the tumor antigens and are able to eliminate the cancer cells. Ye and colleagues now found that many of these tumor-reactive T cells are marked by expressing CD137, a T-cell costimulatory receptor.
