Role of the Dll4-Notch axis in cardiometabolic disorders. The Dll4-Notch axis activates the NF-κB pathway. Activation of NF-κB increases the expression of MCP-1, which leads to the accumulation and proinflammatory activation of macrophages in organs such as arteries and adipose tissue. Accumulation of activated macrophages contributes to the pathogenesis of cardiometabolic disorders, including atherosclerotic vascular diseases and insulin resistance.
