Pembrolizumab (MK-3475) is a humanized IgG4 antibody inhibiting the programmed cell death 1 (PD-1) receptor, used in cancer immunotherapy.
Pembrolizumab (MK-3475) increases the secretion of cytokines IFN-γ, TNF-α and the apoptotic cell death of A549 cells[2].
Pembrolizumab improves the αROR1-CAR T-mediated cytotoxicity, and reduces tumorigenesis in the co-cultured αROR1-CAR T and A549 cells by blocking PD-1::PD-L1 interaction in αROR1-CAR T cells[2].
Pembrolizumab inhibits tumor size in A549 xenograft mice pretreated by pressure[2].
