Abstract Dual targeting of the programmed death ligand 1 (PD-L1) and transforming growth factor β (TGFβ) pathways, 2 key mediators tumor immune evasion, may provide synergistic antitumor activity. The novel bifunctional fusion protein M7824 (MSB0011359C) is a fully human IgG1 monoclonal antibody against PD-L1, fused via glycine-serine linker at CH3-C terminus to extracellular domain TGFβ receptor II, which functions as “trap.” Thus, designed exert independent complementary...

Necroptosis, which is recently recognized as a form of programmed cell death, plays critical role in cancer biology, including tumorigenesis and immunology. It was not only to defend against tumor progression by suppressing adaptive immune responses but also promote metastasis after recruiting inflammatory responses. Thus the crucial necrosis has attracted increasing attention. Due heterogeneity microenvironment (TIME) lung adenocarcinoma (LUAD), prognosis response immunotherapy vary...
