There are other receptors that have been reported to bind to oxLDL which include CD68 and its murine homolog macrosialin, mucins, and LOX-1.
This receptor, also known as macrosialin, is a member of the lysosomal-associated membrane protein (LAMP) family, which is expressed in macrophages, osteoclasts, dendritic cells, and microglia, where its principal role is to bind and uptake oxidized lipoproteins and apoptotic cells [129].
