The low-density lipoprotein receptor (LDL-R) is a mosaic protein of 839 amino acids (after removal of 21-amino acid signal peptide) [5] that mediates the endocytosis of cholesterol-rich low-density lipoprotein (LDL).

Low density lipoprotein receptor-related protein 1 (LRP1), also known as alpha-2-macroglobulin receptor (A2MR), apolipoprotein E receptor (APOER) or cluster of differentiation 91 (CD91), is a protein forming a receptor found in the plasma membrane of cells involved in receptor-mediated endocytosis.
It is caused by the presence of antibodies against anionic phospholipids and β2-glycoprotein I (β2GPI). The anti-β2GPI antibodies are most prevalent in causing the symptoms of the disease. When bound by an antibody, β2GPI begins to interact with monocytes, endothelial cells, and platelets. ApoER2 is thought to play a key role in the process ...
Insulin resistance, or low insulin sensitivity, happens when cells throughout the body don’t respond properly to the hormone insulin, especially cells in muscles, fat and the liver. Insulin is a ...
Suppression of receptor-binding domain of LRP LDLR is due to overexpression of LRPAP (the protein product of LRPAP gene). [13] LRP gives protection across LDL by LRPAP and its downregulation may be subjected for an elevation of LDL and Ab-related neuronal toxicity as LRP supports in binding of ligand and internalization of LRP ligands like apo ...
Class III: LDLR does not properly bind LDL on the cell surface because of a defect in either apolipoprotein B100 (R3500Q) or in LDL-R. Class IV: LDLR bound to LDL does not properly cluster in clathrin-coated pits for receptor-mediated endocytosis (pathway step 2). Class V: LDLR is not recycled back to the cell surface (pathway step 5).
Pattern I, for intermediate, indicates that most LDL particles are very close in size to the normal gaps in the endothelium (26 nm). According to one study, sizes 19.0–20.5 nm were designated as pattern B and LDL sizes 20.6–22 nm were designated as pattern A. [ 16 ] Other studies have shown no such correlation at all.
