| Research Abstract |
Stimulation of the angiotensin II type 1 receptor induces macrophage polarization to inflammatory M1 state and activates macrophage phagocytic function. Angiotensin II type 1 receptor also plays an important role in oxidized LDL-induced macrophage trapping in the atherosclerotic lesions via enhancing CD36 expression and focal adhesion kinase activation. Our results suggest that stimulation of the angiotensin II type 1 receptor modulates macrophage polarity and functions, resulting in atherosclerotic plaque instability.
