Human neutrophils contain thousands of cytoplasmic granules. These membrane-bound organelles act as storage compartments destined for secretion or in the case of azurophil granules, destined for fusion with phagosomes. A small amount of defensin, but perhaps not enough for antimicrobial activity, may be released extracellularly by neutrophils (Ganz 1987).
