The antiphospholipid syndrome and atherosclerosis: clue to pathogenesis

Regulation of blood vessels is intrinsically tied to inflammatory signaling. Recent research suggests that chronic inflammation is associated with atherosclerosis risk. The antiphospholipid syndrome is a prototypic autoimmune disease. Disturbance of blood vessel homeostasis in this disorder may increase risk for atherosclerosis by mechanisms that are direct (through antibody targeting of blood vessel-regulating proteins) or indirect (via inflammatory mechanisms that have recently been implicated in autoantibody-mediated thrombosis).
