It is proved that long term stimulation of the adventitia with some inflammatory cytokines such as platelet activating factor and leukotriene-C4 results in vasospasm and neointimal proliferation in coronary arteries (5).
Injection or transfection of proinflammatory agents into perivascular fat may test whether contiguous inflammation elicits arterial remodeling, akin to studies performed in the adventitia.
Increased synthesis of [alpha]-smooth muscle actin in the adventitia is believed to be an important factor in the remodeling process because cells proliferate more rapidly in the adventitia than in the media after angioplasty.

A similar sheet of human fibroblasts was wrapped around the media to provide the adventitia.
Gene expression was limited to the "adventitia," one of the layers of the carotid artery, and appeared to be preferential for the endothelial cells of the small blood vessels in the adventitia that are most involved in cardiovascular disease.
