In rat hepatocytes, transcytotic vesicular carriers transport the mature 120 x 10(3) Mr form of the polymeric IgA receptor (pIgA-R), with or without its ligand, pIgA, from the sinusoidal to the biliary plasmalemma, where the ectodomain of the receptor is cleaved to produce an 80 x 10(3) Mr fragment that is secreted into the bile. Here we show that cholestasis induced by bile duct ligation resul...
Impaired hepatic bile acid export may contribute to development of cholestatic drug-induced liver injury (DILI). The multidrug resistance-associated proteins (MRP) 3 and 4 are postulated to be compensatory hepatic basolateral bile acid efflux transporters when biliary excretion by the bile salt export pump (BSEP) is impaired. BSEP inhibition is a risk factor for cholestatic DILI. This study aim...
The efflux transporter responsible for the canalicular elimination of bile salts from the hepatocytes is the bile salt export pump (BSEP, ABCB11). Absence or inhibition of this transporter leads to bile salt retention in the hepatocyte and in turn can lead to cholestatic liver disease. We expressed the BSEP/Bsep protein from three species (human, rat, and mouse) in a baculovirus-infected Sf9 sy...
Cholestatic pruritus is one of the most common complaints in patients with liver diseases and intraor posthepatic cholestasis. The mechanisms of cholestatic pruritus remain poorly understood although multiple factors are considered to participate in the pathogenesis of cholestatic pruritus. Recent exciting studies have discovered several G-protein coupled receptors (GPCRs) and endogenous chemic...
Semisynthetic penicillins are widely used antibiotics. Hepatotoxicity (mainly cholestatic) associated with these drugs is a rare, but well described phenomenon.' 2 Several series of cholestatic hepatitis have been reported after treatment with flucloxacillin,2A whereas only isolated cases related to cloxacillin have been described.`'0 Cholestatic jaundice may develop up to seven weeks following...
Obstructive cholestasis is associated with overproduction of endogenous opioids (EOP), nitric oxide (NO), and cytokins in the blood streams. Therefore we investigated the relationship between obstructive cholestasis and function of germ cells in adult male rats.Material and Methods: To study this, we used three groups of animals: No-surgery, Sham-surgery, and surgical ligation of the bile duct....
Phloracetophenone (2,4,6-trihydroxyacetophenone, THA) is a potent choleretic in the bile fistula rat, although the mechanism is unknown. In the present study, we examined how THA enhances bile secretion. Stepwise infusions of THA (1-4 micromol/min) in the isolated perfused rat liver resulted in an immediate and dose-dependent increase in bile flow (BF), which reached saturation. The increase in...
Cholestatic jaundice and elevated liver enzymes are uncommon, but recognized, manifestations of neonatal thyrotoxicosis. Current guidelines for evaluation of cholestatic jaundice and reviews in Neonatology literature do not discuss hyperthyroidism in the differential diagnosis of cholestatic jaundice. We report two cases of neonatal thyrotoxicosis secondary to neonatal Graves’ disease that pres...
