Abstract:

To shed light on ductular fluid secretion, hepatic histology and ultrastructure, cell proliferation and phenotypes, and several aspects of biliary physiology were studied in rats with ductular cell hyperplasia induced by either biliary obstruction (0-14 days) or 1-naphthylisothiocyanate (ANIT) feeding (0-28 days). In both groups of experimental animals, bile duct hyperplasia and spontaneous bile flow and secretin-induced choleresis increased with time of treatment in a linear fashion. Measurements of [14C]mannitol biliary entry and of biliary tree volume showed that the increase in both sponta

Abstract:

Abstract Context.—Diagnosis of biliary neoplasia can be challenging but is essential for the appropriate clinical management of patients. Therefore, it is important to recognize the morphologic features of the biliary neoplasms to report a correct diagnosis. Objectives.—(1) To discuss the differential diagnosis of dysplasia in the gallbladder and differentiate dysplasia from reactive atypia and invasive carcinoma, (2) review the histologic features of adenoma and polypoid biliary lesions, (3) highlight the differential diagnosis of adenocarcinoma in liver biopsy, and (4) discuss the differenti

Abstract:

Cholangiopathies encompass various biliary diseases affecting the biliary epithelium, resulting in cholestasis, inflammation, fibrosis, and ultimately liver cirrhosis. Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are the most important progressive cholangiopathies in adults. Much research has broadened the scope of disease biology to genetic risk, epigenetic changes, dysregulated mucosal immunity, altered biliary epithelial cell function, and dysbiosis, all of which interact and arise in the context of ill-defined environmental triggers.

Abstract:

ABSTRACT Biliary atresia is a devastating disorder of the newborn in which afflicted infants develop inflammation and fibrosis of the extrahepatic biliary tract, resulting in cirrhosis and end-stage liver disease. Infection with a virus is thought to be a contributing factor in the etiology of biliary atresia. In the murine model of biliary atresia, perinatal exposure to rhesus rotavirus (RRV) results in biliary epithelial cell infection causing bile duct obstruction. The purpose of this study was to determine if tropism for the biliary epithelial cell was unique to RRV. Newborn mice underwent

Abstract:

The biliary system has a close developmental relationship with the pancreas, evidenced by the natural occurrence of small numbers of biliary-derived β-cells in the biliary system and by the replacement of biliary epithelium with pancreatic tissue in mice lacking the transcription factor Hes1. In normal pancreatic development, Hes1 is known to repress endocrine cell formation. Here we show that glucose-responsive insulin secretion can be induced in biliary epithelial cells when activity of the transcription factor Hes1 is antagonised.

Chronic diseases of the biliary tree (cholangiopathies) represent one of the major unmet needs in clinical hepatology and a significant knowledge gap in liver pathophysiology. The common theme in cholangiopathies is that the target of the disease is the biliary tree. After damage to the biliary epithelium, inflammatory changes stimulate a reparative response with proliferation of cholangiocytes and restoration of the biliary architecture, owing to the reactivation of a variety of morphogenetic signals. Chronic damage and inflammation will ultimately result in pathological repair with generatio

Histopathological findings in liver biopsies include the expansion of the portal tracts, with edematous fibroplasia and bile ductular proliferation, with bile plugs in duct lumen. Lobular morphological features may include variable multinucleate giant cells, bilirubinostasis and hemopoiesis. The etiopathogenesis of biliary atresia is multifactorial and multiple pathomechanisms have been proposed. Experimental and

Abstract:

Immortalized bile duct cells (BDC), derived from transgenic mice harboring the SV40 thermosensitive immortalizing mutant gene ts458, were utilized to investigate the role of the biliary epithelium in lipid and sterol metabolism. This cell model closely resembles the in vivo situation because it expresses the specific phenotypic marker cytokeratin 19 (CK-19), exhibits the formation of bile duct-like structures, and displays well-formed microvilli projected from the apical side to central lumen. The BDC were found to incorporate [14C]oleic acid (in nmol/mg protein) into triglycerides (121 ± 6),

Abstract:

SummaryIdentifying bile duct epithelium is sometimes difficult with standard histologie techniques. The availability of antibodies to specific cy tokeratin (CK) intermediate filaments has allowed identification of CK expressed by bile duct epithelium. Formalin‐fixed, paraffin‐embedded liver tissue from five infants (aged 1–12 months) with Alagille syndrome and five infants with biliary atresia (aged 1.5–11 months) were pepsin digested then reacted with a combination of anti‐cytokeratin monoclonal antibodies using an avidin‐biotin immunoper‐oxidase technique. Liver tissue obtained at autopsy fr

Abstract:

ObjectiveWe explored the hypothesis that TGR5, the bile acid (BA) G-protein-coupled receptor highly expressed in biliary epithelial cells, protects the liver against BA overload through the regulation of biliary epithelium permeability.DesignExperiments were performed under basal and TGR5 agonist treatment. In vitro transepithelial electric resistance (TER) and FITC-dextran diffusion were measured in different cell lines. In vivo FITC-dextran was injected in the gallbladder (GB) lumen and traced in plasma. Tight junction proteins and TGR5-induced signalling were investigated in vitro and in vi

Abstract:

Three children, two with liver transplants and one with acquired human immunodeficiency virus (HIV) infection, presented with hepatitis accompanied by elevated gamma glutamyl transpeptidase. Biopsies revealed cholangiohepatitis caused by adenovirus infection. There was a progressive loss of interlobular bile ducts in two of the patients. In one patient, infection of the biliary tree was marked by a necrotizing cholangitis, with adenoviral inclusions noted in the biliary epithelium. In each patient, there was evidence of adenovirus gastrointestinal infection. This is the first report of adenovi

Abstract:

Mucinous cystic neoplasm configures as a cystic neoplasm incriminating the hepatic parenchyma. Tumour is constituted of multi-locular or cystic cavity layered with mucinous or biliary type epithelium encompassed within an ovarian type stroma. The cystic lesion appears non communicative with adjoining bile ducts. Additionally designated as hepatobiliary cystadenoma, biliary cystadenoma or cystadenoma with mesenchymal stroma, neoplasms associated with invasive carcinoma component may be denominated as hepatobiliary cystadenocarcinoma.

Abstract:

The bile duct epithelium is known to modify hepatic bile by both secretory and absorptive processes. However, identification and characterization of the transport systems that carry out these physiological functions at the cellular and molecular level have been slow compared with progress in understanding hepatic bile production. Recently, techniques have been developed that enable bile duct cells to be isolated in substantial number and purity and as intact polarized units that can be studied in vitro. These newer preparations have enabled classic physiological approaches to be performed dire

This case report describes an extremely rare association between gallbladder agenesis and choledochal cyst (CC). A 9-year-old girl presented with recurrent abdominal pain in the right upper quadrant. Radiological studies revealed a CC type IVa and an agenesis of gallbladder and cystic duct. Due to the possibility of biliary neoplasm, the patient underwent cyst resection and hepaticoduodenostomy. Histopathological findings showed inflamed fibrous tissue covered by biliary epithelium with no evidence of malignancy.

AbstractCystoisospora(Isospora)belliis a coccidian parasite of humans. It can cause serious digestive disorders involving infection of intestines, biliary tract and gallbladder, especially in those with depressed immunity. It has a direct fecal–oral transmission cycle. After ingestion of sporulated oocysts, the parasite multiplies asexually and sexually within host epithelial cells, resulting in unsporulated oocysts that are excreted in feces. The details of asexual and sexual stages are not known and certain inclusions in epithelial cells in biopsy samples have been erroneously identified rec
