Investigations of high-density lipoproteins (HDL) isolated from the blood of patients with coronary heart disease, type 2 diabetes mellitus, rheumatic and kidney diseases, and metabolic syndrome revealed dysfunction of HDL in the replacement of their proteins (primarily apoA-1) with other proteins that had no atheroprotective properties. The displacement of the antioxidant protein paraoxonase 1 from the particles of HDL leads to the loss of the antioxidant effect of the latter particularly on low-density lipoproteins and arterial wall endothelium, as well as anti-inflammatory action, that of inhibition of the enzyme nitric oxide (NO) synthase and production of the vasodilator NO, as well as regulatory action on platelets. Posttranslational modifications of proteins and modifications of the lipid components reducing the anti-atherogenic functions of HDL were found. The ultimate goal of studies of HDL, which is the possible effective use of the latter to obtain recombinant forms that could be used for therapeutic or preventive purposes, has not yet been achieved, but the causes of transformation of classical anti-atherogenic HDL into their atherogenic forms were identified. These data are the basis for creating a diagnostic system, namely, a panel of «atheromarkers of HDL».
