Summary
Microfibril-associated glycoprotein-1 (MAGP-1), a critical component of extracellular matrix (ECM) microfibrils, plays a pivotal role in liver fibrosis, although its precise function in this process remains elusive. Our research underscores that MAGP-1 (Mfap2) is predominantly expressed in activated hepatic stellate cells (HSCs) and exhibits heightened levels in advanced liver fibrosis. Deletion of MAGP-1 showcased limited impact on overall collagen deposition following CCl4 stimulation. However, it notably heightened intrahepatic inflammatory infiltration within lobular regions, hastened ECM stabilization through the upregulation of insoluble matrisome constituents within the ECM, and triggered focal adhesion (FA) signaling in HSCs, hindering the regression of liver fibrosis upon cessation of CCl4 treatment.
