Cytotoxicity t cells
WebThere are two major types of T cells: the helper T cell and the cytotoxic T cell. As the names suggest helper T cells ‘help’ other cells of the immune system, whilst cytotoxic T … Webcytotoxic T-cell frequency could already be seen. The closer to relapse, the higher PD-L1C cytotoxic T-cell frequencies were (p D 0.021, CC 0.829), suggesting that PD-L1C cytotoxic T-cells could be relevant to detect impending or subclinical relapse. Next, the relation of PD-L1 to IDO and Tregs was assessed. A
