Abstract
EOSINOPHILS are phagocytic cells, and granules adjacent to the phagocytic vacuolo rupture1. Eosinophil granules contain a number of acid hydrolases together with basic protein and peroxidase2 and during phagocytosis these substances are discharged from the disrupted granules into, or alongside, the phagocytic vacuole. The acid hydrolases released from eosinophil granules probably have a digestive function, but the significance of the other granule components is not known. This work reports the presence in eosinophil granules of a substance capable of causing the disruption of mast cells. The active principle appears to be associated with the enzyme peroxidase.
