How macrophages use extracellular calreticulin to chase their prey

Recent findings reveal that macrophages actively control clearance by desialylating target cells via NEU1 and releasing cathepsin-cleaved calreticulin (CALR) to mark them for phagocytosis. This uncovers a dual role for CALR as immune activator or repressor, depending on its form and context, with di...

description Recent findings reveal that macrophages actively control clearance by desialylating target cells via NEU1 and releasing cathepsin-cleaved calreticulin (CALR) to mark them for phagocytosis. This uncovers a dual role for CALR as immune activator or repressor, depending on its form and context, with distinct implications for cancer immunity.
