Costimulatory definition
WebCostimulation may occur in two ways: Cytokines, released by helper T cells and APCs, act as costimulators. Cytokines are protein hormones that influence cell growth. When a helper T cell becomes activated or an APC engulfs an antigen, the helper T cell or APC secretes a cytokine called interleukin. Helper T cells and APCs act as costimulators. WebOct 1, 2016 · Signaling through various immune checkpoints and downregulation of costimulatory receptors each represent a distinct mechanism of tumor-mediated immunosuppression. Combining inhibitors that target different checkpoints is a logical strategy to generate synergy and target potential mechanisms of resistance to therapy.
