[Lipoproteins of the vascular wall: complex formation with glycosaminoglycans and interaction with foam cells].

Atherogenic lipoproteins are present in the aortic wall in complexes with various glycosaminoglycans. Reduced uptake of 125I-lipoproteins of low density by the foam cells and diminished respiration-stimulating effect of low-density lipoproteins on the cells under the influence of glycosaminoglycans reflects the capacity of glycosaminoglycans for changing the physico-chemical properties of lipoproteins in the direction of a decrease in their interaction with the foam cells.
