Mathematical models disentangle the role of IL-10 feedbacks in human monocytes upon proinflammatory activation.

Inflammation is one of the vital mechanisms through which the immune system responds to harmful stimuli. During inflammation, proinflammatory and anti-inflammatory cytokines interplay to orchestrate fine-tuned and dynamic immune responses. The cytokine interplay governs switches in the inflammatory response and dictates the propagation and development of the inflammatory response.

Improvement of portal venous pressure in cirrhotic rat livers by systemic treatment with adipose tissue-derived mesenchymal stromal cells.

Background Aims: Portal hypertension is the main cause of complications in cirrhosis caused primarily by extensive fibrosis. Both anti-fibrotic and pro-fibrotic properties of mesenchymal stromal cells (MSCs) have been described in various animal models of liver fibrosis. Therefore, the impact of MSCs on portal hypertension and fibrosis should be investigated in an animal model of liver cirrhosis.

Expression of glyoxalase-I is reduced in cirrhotic livers: A possible mechanism in the development of cirrhosis.

Background: High concentrations of methylglyoxal (MGO) cause cytotoxiticy via formation of advanced glycation endproducts (AGEs) and inflammation. MGO is detoxificated enzymatically by glyoxalase-I (Glo-I). The aim of this study was to analyze the role of Glo-I during the development of cirrhosis.

Plasma Membrane Phosphatidylinositol 4,5-Bisphosphate Regulates Ca(2+)-Influx and Insulin Secretion from Pancreatic β Cells.

Insulin secretion from pancreatic β cells is regulated by the blood glucose concentration and occurs through Ca(2+)-triggered exocytosis. The activities of multiple ion channels in the β cell plasma membrane are required to fine-tune insulin secretion in order to maintain normoglycemia. Phosphoinositide lipids in the plasma membrane often gate ion channels, and variations in the concentration of these lipids affect ion-channel open probability and conductance.

Hepatic arterial vasodilation is independent of portal hypertension in early stages of cirrhosis.

Introduction: The compensatory increase in hepatic arterial flow with a decrease in portal venous flow is known as the hepatic arterial buffer response. In cirrhosis with elevated portal pressure, the vascular resistance of the hepatic artery is decreased. Whether this lower resistance of the hepatic artery is a consequence of portal hypertension or not remains unknown.
