LRP1 Functions as an Atheroprotective Integrator of TGFβ and PDGF Signals in the Vascular Wall: Implications for Marfan Syndrome

BACKGROUND The multifunctional receptor LRP1 controls expression, activity and trafficking of the PDGF receptor-beta in vascular smooth muscle cells (VSMC). LRP1 is also a receptor for TGFbeta1 and is required for TGFbeta mediated inhibition of cell proliferation. METHODS AND PRINCIPAL FINDINGS We show that loss of LRP1 in VSMC (smLRP(-)) in vivo results in a Marfan-like syndrome with nuclear...

LRP1 integrates murine macrophage cholesterol homeostasis and inflammatory responses in atherosclerosis

Low-density lipoprotein receptor-related protein 1 (LRP1) is a multifunctional cell surface receptor with diverse physiological roles, ranging from cellular uptake of lipoproteins and other cargo by endocytosis to sensor of the extracellular environment and integrator of a wide range of signaling mechanisms. As a chylomicron remnant receptor, LRP1 controls systemic lipid metabolism in concert w...

LRP1 Regulates Architecture of the Vascular Wall by Controlling PDGFRβ-Dependent Phosphatidylinositol 3-Kinase Activation

BACKGROUND Low density lipoprotein receptor-related protein 1 (LRP1) protects against atherosclerosis by regulating the activation of platelet-derived growth factor receptor beta (PDGFRbeta) in vascular smooth muscle cells (SMCs). Activated PDGFRbeta undergoes tyrosine phosphorylation and subsequently interacts with various signaling molecules, including phosphatidylinositol 3-kinase (PI3K), wh...

Informative STR Markers for Marfan Syndrome in Birjand, Iran

Objective(s)Marfan syndrome (MFS) is a severe connective tissue disorder withan autosomal dominant inheritance pattern. Early diagnosis is critical in MFS. Because of the large size of fibrillin-1 gene (FBN1), the uniqueness of mutations, and the absence of genotype-to-phenotype correlations linkage analysis can be very helpful for early diagnosis of MFS. In this study, eight polymorphic marker...

LDL receptor-related protein and the vascular wall: implications for atherothrombosis.

LDL receptor-related protein 1 (LRP1) is highly expressed in the vascular wall and is mainly associated with macrophages and vascular smooth muscle cells (VSMCs). Overexpression of LRP1 in atherosclerotic lesions has been demonstrated in several animal models and human lesions. Clinical studies have suggested a relation between alterations in LRP1 expression and coronary heart disease. Indeed, ...
