Protein disulfide isomerase regulates blood vessel caliber in vascular disease

Redoxoma Highlights | F. LaurindoPDI regulates blood vessel caliber in vascular disease

While the intuitive idea is that the lumen of diseased blood vessels narrows due to the pathological growth of a migrating cell mass, similar to rust in an old pipe, actually the lumen of diseased vessels is strongly influenced by a phenomenon called vascular remodeling, the structural reorganization of whole-vessel circumference. Typically, remodeling is the sole determinant of vessel lumen due to blood flow changes, in which redox signaling processes play an important mediator role in association with NO biovailability. However, redox processes appear to mediate other forms of vascular remodeling as well, such as those associated with atherosclerosis-related processes. We showed previously
