etabolic syndrome (MetS) is a highly prevalent disorder which can be used to identifyindividuals with a higher risk for cardiovascular disease and type 2 diabetes. This metabolic syndromeis characterized by a combination of physiological, metabolic, and molecular alterations such asinsulin resistance, dyslipidemia, and central obesity. The low-density lipoprotein receptor-relatedprotein 1 (LRP1?A member of the LDL receptor family) is an endocytic and signaling receptorthat is expressed in several tissues. It is involved in the clearance of chylomicron remnants fromcirculation, and has been demonstrated to play a key role in the lipid metabolism at the hepaticlevel. Recent studies have shown that LRP1 is involved in insulin receptor (IR) trafficking andintracellular signaling activity, which have an impact on the regulation of glucose homeostasisin adipocytes, muscle cells, and brain. In addition, LRP1 has the potential to inhibit or sustaininflammation in macrophages, depending on its
