Mechanisms of Perivascular Adipose Tissue Dysfunction in Obesity
Most blood vessels are surrounded by adipose tissue. Similarly to the adventitia, perivascular adipose tissue (PVAT) was considered only as a passive structural support for the vasculature, and it was routinely removed for isolated blood vessel studies. In 1991, Soltis and Cassis demonstrated for the first time that PVAT reduced contractions to noradrenaline in rat aorta. Since then, an importa...
متن کاملPerivascular adipose tissue, potassium channels, and vascular dysfunction.
Perivascular adipose tissue has been recognized unequivocally as a major player in the pathology of metabolic and cardiovascular diseases. Through its production of adipokines and the release of other thus far unidentified factors, this recently discovered adipose tissue modulates vascular regulation and the myogenic response. After the discovery of its ability to diminish the vessel's response...
متن کاملFAS and ACC dysfunction in visceral Adipose Tissue
Background and Aim: A great interest for determining the particular mechanisms underlying lipogenesis and adipogenesis has been raised among researchers in order to fight obesity. We aimed to investigate the gene expression of FAS and its role in regulation of lipogenesis and adipogenesis in visceral adipose tissues from obese and normal-weight subjects. materials and Methods: A total of.parti...
متن کاملPerivascular adipose tissue contains functional catecholamines
The sympathetic nervous system and its neurotransmitter effectors are undeniably important to blood pressure control. We made the novel discovery that perivascular adipose tissue (PVAT) contains significant concentrations of catecholamines. We hypothesized that PVAT contains sufficient releasable catecholamines to affect vascular function. HPLC, isometric contractility, immunohistochemistry, wh...
متن کاملWild blueberry consumption attenuates local inflammation in the perivascular adipose tissue of obese Zucker rats.
Perivascular adipose tissue (PVAT) has been shown to play important roles in regulating vascular tone and linking local and systemic vascular inflammation. We examined the impact of PVAT on phenylephrine-mediated vasoconstriction in the aorta of obese Zucker rats (OZR) and their lean littermates (LZR) by comparing aortic rings with or without PVAT. Subsequently we placed OZR and LZR on a contro...
