Macrophage MerTK promotes profibrogenic cross-talk with hepatic stellate cells via soluble mediators

2022

Background & aims: Activation of Kupffer cells and recruitment of monocytes are key events in fibrogenesis. These cells release soluble mediators which induce the activation of hepatic stellate cells (HSCs), the main fibrogenic cell type within the liver. Mer tyrosine kinase (MerTK) signaling regulates multiple processes in macrophages and has been implicated in the pathogenesis of non-alcoholic steatohepatitis-related fibrosis. In this study, we explored if MerTK activation in macrophages influences the profibrogenic phenotype of HSCs. Methods: Macrophages were derived from THP-1 cells or differentiated from peripheral blood monocytes towards MerTK+/CD206+/CD163+/CD209- macrophages. Th…

Cyclooxygenase-2 (COX-2), vascular endothelial growth factor-A (VEGF-A), and tumor necrosis factor-α (TNF-α) are mediators of inflammation and angiogenesis; all of them are produced in liver cirrhosis (LC) and in hepatocellular carcinoma (HCC). It was proposed that there is an association between single nucleotide polymorphisms (SNPs) and HCC. These allelic variants influence the transcriptional activity of these genes, and therefore the proteins levels. The VEGF-A pathway is a potential therapeutic target in HCC, and several antiangiogenic agents have entered clinical trials in HCC. We evaluated the frequency of SNPs of COX-2, TNF-α, and VEGF-A genes in patients with HCC versus LC patients…
