Exocytosis of intracellular granules is critical for conversion of inactive, circulating neutrophils to fully activated cells. The p38 MAPK pathway plays a central role in neutrophil exocytosis, although its mechanism of action is unknown. We used...
BACKGROUND: Regulated secretion of protein by salivary and other exocrine glands requires correct trafficking of soluble cargo proteins into secretory vesicles. However, the molecular mechanism of sorting in the parotid salivary gland is unknown....
