Figure 9. Mechanisms of hypertensive arterial remodelling.
M2-type Mφs are recruited to the aortic adventitia after blood-pressure elevation and secrete C1q. Mφ-derived C1q and VSMC-derived C1r/s might compose the C1 complex, which plays a pivotal role in initiating hypertensive arterial remodelling through activating β-catenin signalling in VSMCs and inducing proliferation of VSMCs.
