Loss of PIKfyve in platelets causes a lysosomal disease leading to inflammation and thrombosis in mice

PIKfyve is a lipid kinase essential for regulation of membrane homeostasis and vesicle trafficking along the endosomal-lysosomal pathway. Here the authors show that mice lacking PIKfyve exclusively in their platelets exhibit a systemic disorder characterized by multi-organ inflammation and thrombosis due to aberrant platelet lysosome function.
