Other cells that express LOX-1 include macrophages, platelets, fibroblasts, and vascular smooth muscle cells (SMCs) that explain multi-level involvement of LOX-1 in atherosclerosis (Chen et al., 2001[3]; Kataoka et al., 2001[12]; Yoshida et al., 1998[25]). This evidence concerns the gene OLR1 and atherosclerosis.
