Mechanisms of vasodilatatory effect of perivascular tissue of human internal thoracic artery.
It has beed showed that perivascular adipose tissue (PVAT) of human internal thoracic artery (ITA) releases adventitia/adipocyte-derived relaxing factor (ADRF). The precise mechanism of vasodilatatory effect of ADRF is still unknown. It was suggested that various potassium channels may be involved in the action of ADRF. The aim of this study was to assess the involvment of potassium channels in...
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 کاملThe influence of perivascular adipose tissue on vascular homeostasis
The perivascular adipose tissue (PVAT) is now recognized as an active contributor to vascular function. Adipocytes and stromal cells contained within PVAT are a source of an ever-growing list of molecules with varied paracrine effects on the underlying smooth muscle and endothelial cells, including adipokines, cytokines, reactive oxygen species, and gaseous compounds. Their secretion is regulat...
متن کاملThe internal thoracic artery in human foetuses.
The aim of this study was to examine the internal thoracic artery (ITA) in human foetuses. The research material consisted of 32 human foetuses (18 female, 14 male) from the 21(st) to 24(th) week of intrauterine life. After intravascular injection with white latex LBS 3060, the foetuses were fixed in 10% neutral formalin solution. The whole course of the ITA was prepared. Photographic documenta...
