英文摘要
In the present study, we investigated the mechanism(s) of PPARγ activation by inhibiting cPLA_2 on macrophages, and the anti-atherosclerotic effect of cPLA2 inhibition in macrophages and apoE-deficient mice. We revealed that cPLA_2 inhibition induced cyclooxygenase-2 expression and subsequent 15d-PGJ_2 production, resulting PPARγ activation in macrophages. Inhibition of cPLA2 suppressed LPS-induced TNF-α and MCP-1 expression, and induced ABCA1/G1 expression. Moreover, administration of cPLA_2 inhibitor, AACOCF3 suppressed the progression of atherosclerosis in apoE-deficient mice. These results suggest that cPLA2 inhibition has anti-atherosclerotic effects, and cPLA2 may be one of the therapeutic targets for diabetic macrovascular complications.
