Abstract: The end of the previous century brought new findings concerning the role of inflammation and the infectious agents in the development of atherosclerosis. However, it is still not clear whether and how the infectious agents participate in the formation and the development of the atherosclerotic plaque. This article discusses the findings which to confirm the hypothesis that the bacterial Hsp proteins are factors promoting the autoimmune reactions and pathological processes leading to coronary heart disease. The involvement of bacterial Hsp proteins in the atherosclerotic processes is probably based on the upregulation of anti-Hsp60 autoantibodies produced in response to infection with a pathogen which produces Hsp60. Since the Hsp proteins are very conservative, the antibodies produced in response to bacterial Hsp60 may react with the human analogue Hsp60 exposed on the surface of endothelium. The complexes of autoantibodies and human Hsp60 proteins may induce the complement dependent cytotoxicity and promote inflammatory damage of the vessels.
