The inflammatory response is a nonspecific response that occurs if a foreign invader gets past the five m ...

Adaptive immune resistance is a mechanism by which tumor cells limit host immune response via upregulation of the programmed death-ligand 1 (PD-L1) and ligation to the programmed death-1 (PD1) receptor on antigen-specific CD8 T cells. Recent studies of the PD-1 checkpoint inhibitor in nonsmall cell ...
