Cholangiocytes function
In the healthy liver, cholangiocytes contribute to bile secretion via release of bicarbonate and water. Several hormones and locally acting mediators are known to contribute to cholangiocyte fluid/electrolyte secretion. These include secretin, acetylcholine, ATP, and bombesin. Cholangiocytes act through bile-acid independent bile flow, which is driven by the active transport of electrolytes. In contrast, hepatocytes secrete bile through bile-acid dependent bile flow, which … WebSep 12, 2024 · Bile is a fundamental and unique secretion of the liver. It is a yellow-greenish fluid that is secreted from the hepatocytes and altered as it passes through the biliary tree by the epithelial cells lining the bile-duct (cholangiocytes). After its secretion, bile is stored and concentrated in the gallbladder. The presence of lipids in the duodenum stimulates the …
