[Mechanisms of generating calcium signals in exocrine acinar cells].

Review. Modern data about mechanisms of generation of the calcium signals in the exocrine acinar cells are presented. The mechanisms of inositol-1,4,5-trisphosphate- and Ca(2+)-induced Ca2+ release from intracellular stores of the acinar cells and mechanisms their influx from extracellular medium are described. The mechanisms which initiate Ca2+ oscillations and their role in the secretion of the fluid and enzymes by acinar cells are discussed.
