Sažetak
Heat shock proteins (Hsps) are produced by all cells, including vascular, to ensure stress protection. Damaged cells release Hsps in their local environment and systemic circulation. The aim of this study was to investigate the involvement and prognostic utility of serum Hsp60 and Hsp70, and the respective antibodies anti-Hsp60 and anti-Hsp70 in subjects with advanced atherosclerosis resulting in high degree of cerebrovascular stenosis. Ultrasound doppler examination of carotid arteries was used to discriminate between control and cerebrovascular atherosclerosis subjects. Twenty eight subjects without carotid obstruction were selected as controls. Fifty patients with obstruction of cerebrovascular blood flow were evaluated for the degree of stenosis of cerebral arteries by digital subtraction angiography. In parallel, serum concentrations of Hsp60, Hsp70, anti-Hsp60 and anti-Hsp70 were measured by ELISA kits. Anti-Hsp60 was significantly higher (P=0.003) in the atherosclerosis group than in the control group (23.62 ng/L vs. 15.28 ng/L, respectively, expressed as median). Circulating Hsp70 was lower in the atherosclerosis than in the control group (P=0.048), with respective median values of 0.00 µg/L vs. 0.22 µg/L). Concentrations of Hsp60 and anti-Hsp70 did not differ significantly between the control and atherosclerosis group. Higher circulating anti-Hsp60 is associated with advanced cerebrovascular atherosclerosis as a consequence of the autoimmunity part of the inflammation and bursting of atherosclerosis. Higher levels of Hsp70 observed in the control group could be protective in the development of atherosclerotic changes.
