The “HDL receptor” scavenger receptor class B type 1 finesses the uptake of low-density lipoproteins into the subendothelial space of arteries

Atherosclerosis is a chronic inflammation initiated by the accumulation of low-density lipoproteins (LDL) in the subendothelial space of the artery wall in spatially selected regions of the artery. The LDL is derived from circulating plasma lipoproteins. The passage of macromolecules across the endothelial barrier may involve one of three mechanisms—diffusional, paracellular or transcellular.
