Flow-induced vascular remodeling in the mouse: a model for carotid intima-media thickening.
OBJECTIVE Vascular remodeling of the carotid artery with intima-media thickness (IMT) is an important predictive factor for human cardiovascular disease. We characterized a mouse model of vascular remodeling. METHODS AND RESULTS The left external and internal carotid branches were ligated so that left carotid blood flow was reduced to flow via the occipital artery. In response to partial liga...
متن کاملp47phox-dependent NADPH oxidase regulates flow-induced vascular remodeling.
Chronic alterations in blood flow elicit an adaptive response that tends to normalize shear stress, involving nitric oxide (NO) and matrix metalloproteinases (MMPs). To evaluate the role of NADPH oxidase in this process, we developed a new model of mouse arteriovenous fistula (AVF) connecting the right common carotid artery (RCCA) with the jugular vein, which does not affect blood pressure. Mic...
متن کاملAxl, a receptor tyrosine kinase, mediates flow-induced vascular remodeling.
Intima-media thickening (IMT) in response to hemodynamic stress is a physiological process that requires coordinated signaling among endothelial, inflammatory, and vascular smooth muscle cells (VSMC). Axl, a receptor tyrosine kinase, whose ligand is Gas6, is highly induced in VSMC after carotid injury. Because Axl regulates cell migration, phagocytosis and apoptosis, we hypothesized that Axl wo...
متن کاملPECAM-1 is necessary for flow-induced vascular remodeling.
OBJECTIVE Vascular remodeling is a physiological process that occurs in response to long-term changes in hemodynamic conditions, but may also contribute to the pathophysiology of intima-media thickening (IMT) and vascular disease. Shear stress detection by the endothelium is thought to be an important determinant of vascular remodeling. Previous work showed that platelet endothelial cell adhesi...
متن کاملFibronectin is an important regulator of flow-induced vascular remodeling.
OBJECTIVE Fibronectin is an important regulator of cell migration, differentiation, growth, and survival. Our data show that fibronectin also plays an important role in regulating extracellular matrix (ECM) remodeling. Fibronectin circulates in the plasma and is also deposited into the ECM by a cell dependent process. To determine whether fibronectin affects vascular remodeling in vivo, we aske...
