Clearance of Fetuin-A–Containing Calciprotein Particles Is Mediated by Scavenger Receptor-A

We could demonstrate that fetuin-A-containing CPPs facilitate the clearance of mineral debris by macrophages via SR-A. Since the same receptor also contributes to the uptake of modified low-density lipoprotein particles in atherosclerosis, defective endocytosis of both types of particle may impinge on lipid as well as mineral debris clearance in calcifying atherosclerosis.
