PCSK9-regulated migratory capacity of monocytes. PCSK9 decreases the LDLR on the cell surface of a monocyte. As a result, the accumulated circulating low-density lipoprotein-cholesterol (LDL-C) stimulates the expression of C–C chemokine receptor 2 (CCR2), which serves as the receptor of MCP-1. Thus, the monocyte can migrate towards MCP-1 and accumulate in the arterial wall
