Excessive Ca2+ influx mediates many cytotoxic processes, including those associated with autoimmune inflammatory diseases such as acute pancreatitis and Sjögren's syndrome. TRPC3 is a major Ca2+ influx channel in pancreatic and salivary gland cells. We investigated whether genetic or pharmacological inhibition of TRPC3 protects pancreas and salivary glands from Ca2+-dependent damage. We developed a Ca2+-dependent model of cell damage for salivary gland acini. Acute pancreatitis was induced by injection of cerulein into wild-type and Trpc3−/− mice. Mice were also given the Trpc3-selective inhibitor pyrazole 3 (Pyr3). Salivary glands and pancreas of Trpc3−/− mice were protected from Ca2+-mediated cell toxicity. Analysis of Ca2+ signaling in wild-type and Trpc3−/− acini showed that Pyr3 is highly specific inhibitor of Tprc3; it protected salivary glands and pancreas cells from Ca2+-mediated toxicity by inhibiting the Trpc3-mediated component of Ca2+ influx. TRPC3-mediated Ca2+ influx mediates damage to pancreas and salivary glands. Pharmacological inhibition of TRPC3 with the highly selective TRPC3 inhibitor Pyr3 might be developed for treatment of patients with acute pancreatitis and Sjögren's syndrome.
