“My name is T-Cell…, James T-Cell” Immune T-cells are licensed to kill other cells through a quick molecular kiss of death, and as such are potentially powerful allies in controlling a tumor. For obvious reasons this killing power is under strict regulatory control and in particular T-cells display PD-1 proteins on their surface, which when engaged by the ligand PD-L1 on another cell, protects that cell from being killed. Tumors often display high levels of PD-L1 so that disrupting the interaction between PD-L1 and PD-1 can enhance the effectiveness of immune killing of tumor cells. Amplifying results from last year … Read More
