The cellular elements of the liver are organized within the sinusoid, with the subendothelial space of Disse separating the epithelium from the sinusoidal endothelium.

Roles of TGF-beta in hepatic fibrosis. Acetaldehyde is then reduced to acetate, most of which is then secreted to the bloodstream 8. Mol Pharmacol ; 48 5: Recommended hepatopatia alcoholica Citing articles 0. Role of H2O2 and cyclooxygenase Reversion and treatment Current questionable trends of thought suggest that reversion of fibrosis may happen by inducing apoptosis or necrosis of activated HSC, or less likely by transformation of activated HSC to a more quiescent phenotype.

Among the noxious effects of hepatipatia are: Early alcoholic liver injury: Am J Physiol ; Rat hepatic stellate cells contribute to the acute-phase response with increased expression of alpha1 I and alpha1 IV collagens, tissue inhibitor of metalloproteinase-1, and matrix-metalloproteinase-2 messenger RNAs.

Exp Mol Med ; Las tres isoformas dismutan el O 2. Springer Semin Immunopathol ; J Clin Invest alcoholicz Mechanisms of suppression of poly I: Activation of stellate cells is mediated by factors released from hepatocytes and Kupffer cells as they produce reactive oxygen species, nitric oxide, cytokines, growth factors, and cyclooxygenase and lipoxygenase metabolites, which provide pivotal paracrine effects in the liver milieu.

Int Rev Cytol ; Gut ; 54 Free Radic Biol Med ; 34 1: Hepatol ; 31 3: Many pathways have been suggested to play a role on how ethanol induces a state of “oxidative stress”, including redox-state changes, acetaldehyde production, damage to mitochondria, membrane injury, apoptosis, ethanol-induced hypoxia, effects on the immune system and altered cytokine production, increased endotoxin levels and activation of Kupffer cells, mobilization of iron, modulation of the antioxidant defense, particularly mitochondrial glutathione GSHone electron oxidation of ethanol to 1-hydroxy-ethyl radical, and induction of CYP2E1.

Many of the metabolic and toxic effects of alcohol in the liver have been associated with its metabolism because it generates toxic metabolites and induces a state of oxidative stress due to activation of CYP2E1, impairment of the mitochondrial function, and a decrease in glutathione stores Bcl-2 protein family members: Alcohol consumption mediates suppression of the innate immunity as decreases NK cells activity and their numbers 99, Front Biosci ; 4: Free Radic Biol Med ; 22 6: The heme oxygenase system: Adipogenic transcriptional regulation of hepatic stellate cells.
