Adipose tissue plays pivotal roles in the development of hypertension,including white and brown adipocytes.Immunity and inflammation provide a bridge between adipose dysfunction and hypertensive target organ damage.We firstly found that perivascular adipose tissue(PVAT)expressed abundant C3,which stimulated adventitial fibroblast migration and phenotype trans-differentiation.Subsequently,we showed that C5a regulated M1/M2 macrophage polarization and inhibited adiponectin production in the PVAT,which contributed to vascular inflammation in hypertension.
