VEGFA and COVID-19: Plasma concentrations of macrophage chemotactic proteins (MCPs) (CCL25, MCP-1, and MCP-3) and key fibrosis mediators [IL10, hepatocyte growth factor, FGF21, FGF23, matrix metalloproteinase 10 (MMP10), transforming growth factor–α (TGFα), and vascular endothelial growth factor] were elevated in patients with COVID-19, whereas integrin subunit alpha 11 (ITGA11) was decreased (Fig. 4D).
