Neuropilin-1 aggravates liver cirrhosis by promoting angiogenesis via VEGFR2-dependent PI3K/Akt pathway in hepatic sinusoidal endothelial cellsResearch in context
Background: We have revealed that neuropilin-1 (NRP-1) promoted hepatic stellate cell activation and liver fibrosis through its profibrogenic signalling pathways. However, the role of NRP-1 in angiogenesis in hepatic sinusoidal endothelial cells (HSECs) during liver cirrhosis remains unclear. Method...

| description | Background: We have revealed that neuropilin-1 (NRP-1) promoted hepatic stellate cell activation and liver fibrosis through its profibrogenic signalling pathways. However, the role of NRP-1 in angiogenesis in hepatic sinusoidal endothelial cells (HSECs) during liver cirrhosis remains unclear. Methods: The correlation between NRP-1 expression and angiogenesis was evaluated in both human and murine cirrhotic liver tissues by immunohistochemical staining, quantitative real-time PCR, and western blotting. In addition, the role and mechanism of NRP-1 in regulating VEGFR2-dependent angiogenesis was identified in endothelial cells (ECs) in vitro. Moreover, liver histocultures were used to test the therapeutic effect of NRP-1 blocking in liver fibrosis. Findings: Higher expression of NRP-1 in HSECs was detected, which was positively correlated with angiogenesis in liver cirrhosis. In vitro, NRP-1 knockdown suppressed the expression and activation of VEGFR2, accompanied by reduced ability of the vascular tube formation and the migration of ECs. Conversely, NRP-1 overexpression upregulated VEGFR2, promoted tube formation, and the migration of ECs. Mechanistically, NRP-1 modulated the expression of VEGFR2 by regulating FAK and its kinase activity. Furthermore, NRP-1 promoted VEGFR2-dependent angiogenesis via the PI3K/Akt pathway in HSECs. Blocking NRP-1 function reduced intrahepatic angiogenesis and fibrosis-associated factors in the in vitro liver histocultures. Interpretation: NRP-1 promotes angiogenesis by upregulating the expression and activation of VEGFR2 through the PI3K/Akt signalling pathway in liver cirrhosis. This study highlights the possibility of therapeutically targeting NRP-1 for the treatment of cirrhosis.
