Lumenal Galectin-9-Lamp2 interaction regulates lysosome and autophagy to prevent pathogenesis in the intestine and pancreas

Galectins are carbohydrate binding proteins previously implicated in sensing and repairing damaged lysosomes. Here, the authors show that galectin-9 has specific lysosomal roles in autophagy and contributes to cell degeneration and apoptosis in colitis and pancreatitis in mice
