Platelet dense granule secretion defects may obscure α-granule secretion mechanisms: evidence from Munc13-4–deficient platelets

To the editor: We were very interested to read in Blood the recent papers by Meng et al, “Defective release of α granule and lysosome content from platelets in mouse Hermansky-Pudlak syndrome models” and by Sharda et al, “Defective PDI release from platelets and endothelial cells impairs
