Interleukin-6 production by human liver (myo)fibroblasts in culture. Evidence for a regulatory role of LPS, IL-1 beta and TNF alpha.

Interleukin-6 is a major trigger for the synthesis of acute phase proteins by liver parenchymal cells. Acute phase proteins may contribute to the regulation of liver fibrosis by inhibition of proteases (e.g. collagenase) and by binding of cytokines. Since liver (myo)fibroblasts play an important role in the production of extracellular matrix in fibrotic livers, a study was undertaken into whether these cells are able to synthesize interleukin-6,...
