Role of heat shock protein 65/60 in the pathogenesis of atherosclerosis

Abstract

Investigations in rabbits and humans have provided experimental evidence that autoimmune reactions play a major role in the initial stages of the development of atherosclerosis. These involve the infiltration of the arterial intima with T cells reacting with heat shock protein (hsp) 65/60 and the occurrence of anti-hsp 65/60 antibodies. This early immunologically mediated stage of atherosclerosis is still reversible but if additional risk factors, such as high cholesterol levels, come into effect, severe mostly irreversible lesions develop.
