Lipoproteins and the liver sieve: The role of the fenestrated sinusoidal endothelium in lipoprotein metabolism, atherosclerosis, and cirrhosis

Robin Fraser, Bruce R. Dobbs, George W. T. Rogers – 1 March 1995 – The liver sieve, formed by the fenestrated hepatic sinusoidal endothelium, is a dynamic biofilter separating the hepatic blood from the plasma within the space of Disse. It filters macromolecules of differing sizes, especially lipoproteins. More specifically, it acts as a barrier to the large triglyceride‐rich parent chylomicrons, while permitting the smaller triglyceride‐depleted but cholesterol‐ and retinol‐rich remnants to enter the space of Disse.

Expression of SPARC in normal and fibrotic livers

Edward Frizell, Shu‐Ling Liu, Ann Abraham, Iwata Ozaki, Mahboubeh Eghbali, E. Helene Sage, Mark A. Zern – 1 March 1995 – SPARC (secreted protein, acidic and rich in cysteine)—also known as osteonectin, BM‐40, and 43K glycoprotein—is secreted by endothelial cells and fibroblasts in response to culture shock. SPARC has been found in association with tissues undergoing cell proliferation, migration, and extracellular matrix remodeling. We demonstrate that normal livers from humans, rats, and mice express substantial levels of SPARC messenger RNA (mRNA).

Endothelin‐1 and ‐3 plasma concentrations in patients with cirrhosis: Role of splanchnic and renal passage and liver function

Alexander L. Gerbes, Søren Møller, Veit Gülberg, Jens H. Henriksen – 1 March 1995 – Increased as well as decreased plasma concentrations of the endothelins, endogenous vasoactive peptides, have been reported in cirrhosis. This might be caused by alterations of hepatic or renal clearance or release. Therefore, the aim of the current study was to investigate the influence of splanchnic and renal passage and of liver function on plasma concentrations of endothelin‐1 (ET‐1) and endothelin‐3 (ET‐3) in patients with cirrhosis compared with controls.

Reovirus 3 not detected by reverse transcriptase—mediated polymerase chain reaction analysis of preserved tissue from infants with cholestatic liver disease

Marilyn I. Steele, Candaca M. Marshall, Richard E. Lloyd, Vicki E. Randolph – 1 March 1995 – Reovirus type 3 has been implicated in the origin and pathogenesis of extrahepatic biliary atresia and idiopathic neonatal hepatitis, but routine detection of this virus in hepatobiliary tissues from affected infants by culture and histological techniques has been unsuccessful.
