Advanced Science, EarlyView.IL‐15‐engineered stem cell–NK cell complexes, assembled via bioorthogonal chemistry, enable effective lung cancer immunotherapy. Abstract Natural killer (NK) cells represent a powerful immunotherapeutic strategy due to their intrinsic cytotoxicity and ability to target tumor cells independently of antigen presentation.

LMO7 Suppresses Tumor‐Associated Macrophage Phagocytosis of Tumor Cells Through Degradation of LRP1
Advanced Science, EarlyView.LMO7 in tumor‐associated macrophages suppresses phagocytosis of tumor cells and limits cytotoxic T lymphocytes infiltration, fostering tumor progression. Mechanistically, LMO7 mediates the ubiquitination and degradation of the phagocytic receptor LRP1, impairing its ability to engulf tumor cells and driving macrophages toward an antitumor phenotype ...

Advanced Science, EarlyView.Phospholipase A2 (PLA2), a dormant enzyme, becomes lethal when activated—collapsing lungs in minutes. Our dual therapy (DOPS + varespladib) boosts survival from 0% to >90% in sepsis/ALI. A breakthrough for acute lung injury treatment. ABSTRACT This study reveals that phospholipase A2 (PLA2), normally stable and nontoxic, can be activated specifically ...
