Adaptive autoimmunity and cholangiocyte apoptosis is increased in PBC by over-activated Th1, Th2, and Th17 cells as a result of decreased immunosuppressive functions of regulatory T cells ... Webbintracellular mechanisms regulating small cholangiocyte proliferation are undefined. There-fore, we sought to address the role and mechanisms of action by which phenylephrine, an a 1-adrenergic agonist stimulating intracellular D-myo-inositol-1,4,5-triphosphate (IP 3)/Ca 21 lev-els, regulates small cholangiocyte proliferation.

WebbWe found that both small and large cholangiocytes expressed GABA receptors. GABA: (i) induced apoptosis of large cholangiocytes and reduced large IBDM; (ii) decreased … 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 is coupled to canalicular secretion of bile acids via ATP-driven transporters. Visa mer Cholangiocytes are the epithelial cells of the bile duct. They are cuboidal epithelium in the small interlobular bile ducts, but become columnar and carbonate-secreting in larger bile ducts approaching the porta hepatis and … Visa mer Active scientific investigation of cholangiocytes focuses on such diverse processes as mechanisms of fluid/electrolyte secretion, regulation of cholangiocyte proliferation, roles of cholangiocytes in the pathogenesis of liver fibrosis and … Visa mer In the healthy liver, cholangiocytes contribute to bile secretion via release of bicarbonate and water. Several hormones and locally acting … Visa mer Disordered functioning of cholangiocytes is at the center of a variety of pathological conditions known as "cholangiopathies." These diseases include Visa mer
WebbCholangiocytes carry out this function through a complex sensing mechanism mediated by a series of receptors, ion channels and sensory signaling molecules found on a structure known as a primary cilia that extends from the apical membrane of the cell into the lumen of the bile duct3. WebbThis cell line is aneuploid, will form colonies in soft agar and retains small cell carcinoma morphology and ultrastructure as well as APUD cell characteristics. The cells grow in aggregates, thus cell counts are not accurate. The cells stain positively for cytokeratins. The line can be adapted to grow in shaker flask or spinner flask systems. The N-myc …
