WebWhile the role of LDLR in cardiovascular disease has been widely studied, only recently the role of other members of the LDLR proteins in lipoprotein homeostasis and atherosclerosis has emerged. LDLR, VLDLR, and LRPs bind and internalize apoE- and apoB-containing lipoprotein, including LDL and VLDL, and regulate their cellular uptake. WebMar 6, 2024 · Cholesterol is a lipophilic molecule that is essential for human life. It has many roles that contribute to normally functioning cells.
