Rictor in perivascular adipose tissue controls vascular function by regulating inflammatory molecule expression.
OBJECTIVE Perivascular adipose tissue (PVAT) wraps blood vessels and modulates vasoreactivity by secretion of vasoactive molecules. Mammalian target of rapamycin complex 2 (mTORC2) has been shown to control inflammation and is expressed in adipose tissue. In this study, we investigated whether adipose-specific deletion of rictor and thereby inactivation of mTORC2 in PVAT may modulate vascular f...
متن کاملPerivascular adipose tissue, vascular reactivity and hypertension.
Most blood vessels are surrounded by a variable amount of adventitial adipose tissue, perivascular adipose tissue (PVAT), which was originally thought to provide mechanical support for the vessel. It is now known that PVAT secretes a number of bioactive substances including vascular endothelial growth factor, tumor necrosis factor-alpha (TNF-α), leptin, adiponectin, insulin-like growth factor, ...
متن کاملPerivascular adipose tissue and coronary vascular disease.
Coronary perivascular adipose tissue is a naturally occurring adipose tissue depot that normally surrounds the major coronary arteries on the surface of the heart. Although originally thought to promote vascular health and integrity, there is a growing body of evidence to support that coronary perivascular adipose tissue displays a distinct phenotype relative to other adipose depots and is capa...
متن کاملEffects of hyperglycemia on the modulation of vascular function by perivascular adipose tissue.
OBJECTIVE To study the acute and chronic effect of hyperglycemia on perivascular adipose tissue (PVAT) function in rat aorta. METHOD Alterations in PVAT function in rat aorta incubated with 22 mmol/l D-glucose for 30 min and in aorta from streptozotocin (STZ)-induced diabetic rats were studied. RESULTS Incubation with D-glucose caused an attenuation of contraction in response to phenylephri...
متن کاملInsulin Receptor Substrate 2 Controls Insulin-Mediated Vasoreactivity and Perivascular Adipose Tissue Function in Muscle
Introduction: Insulin signaling in adipose tissue has been shown to regulate insulin's effects in muscle. In muscle, perivascular adipose tissue (PVAT) and vascular insulin signaling regulate muscle perfusion. Insulin receptor substrate (IRS) 2 has been shown to control adipose tissue function and glucose metabolism, and here we tested the hypothesis that IRS2 mediates insulin's actions on the ...
