[Ca(2+)-signaling in peritoneal macrophages].

Mechanisms of the Ca2+ signal generation and regulation in peritoneal macrophages activated with purinergic agonists (ATP, UTP), as well as endoplasmic Ca(2+)-ATPase inhibitors, were investigated. Using a wide range of drugs affecting the intracellular signaling systems' components, an important role of second messenger systems and other key functional cellular systems in Ca2+ signals regulation in the macrophages, was shown.
