blondinia [14]
The answer is LDL (Low Density Lipoprotein)

Arteriosclerosis is the build up of cholesrol on the inner walls of the arteries. In the long run, arteriosclerosis reduces the diameter of the blood vessels, causing high blood pressure. 
The endothelial cells of arteries have receptors that facilitate binding and transportation of the LDL hence facilitation of their accumulation in the blood vessels.
