Figure 1 Cell and molecular mechanisms of statins. Statins have pleotropic molecular effects. In sinusoidal endothelial cells, they seem to directly affect the eNOS signaling pathway. They activate Akt, which in turn leads to activation of endothelial nitric oxide (NO) synthase (eNOS), resulting in NO production and intrahepatic vasodilation. Statins also seem to have effects on hepatic stellate cells, interrupting a number of signaling cascades, some of which may be involved in their activation, fibrogenesis and/or contractility. There also is the potential for downstream paracrine effects of statins on either sinusoidal endothelial cells or hepatic stellate cells as highlighted by the arrows. Currently available evidence suggests cross talk each way. Together, available data suggest that statins have beneficial effects on both sinusoidal endothelial cells and hepatic stellate cells within the liver.
