[Fibrogenesis in the liver--fibrosis, cirrhosis].
Liver fibrogenesis is a delicately balanced process, in which mainly the non-parenchymal liver cells are implicated. Either increased synthesis or decreased catabolism of matrix proteins results in the enhancement of ECM. As further consequence the formation of continuous diffusion and filtration barriers along the Disse space will hinder the bidirectional exchange of macromolecules. Normal structure of ECM is necessary to the normal function of hepatocytes. The quantitative and qualitative changes of ECM observed in liver fibrosis are able to inhibit the liver specific functions of hepatocytes. The mechanisms involved in this effect are not yet clearly understood. In animal experiments liver cirrhosis is reversible and theoretically the chance is open for humans, as well if we will be able to influence the specific steps of fibrogenesis.
