Vasoactive Peptides
At least 16 naturally occurring peptides either constrict or dilate blood vessels. Many of these peptides are present in nerve cells and nerve terminals supplying systemic and pulmonary blood vessels and the heart. Such neuropeptides are released locally as neurotransmitters, and can influence vascular tone, local and regional blood flow, arterial blood pressure, and cardiac function. There is ...
متن کاملRegulation of apoptosis by vasoactive peptides.
Although originally discovered because of their ability to affect hemodynamics, vasoactive peptides have been found to function in a variety of capacities including neurotransmission, endocrine functions, and the regulation of cell proliferation. A growing body of evidence describes the ability of vasoactive peptides to regulate cell death by apoptosis in either a positive or negative fashion d...
متن کاملRole of sensory nervous system vasoactive peptides in hypertension.
The goal of the present research was to elucidate the roles and mechanisms by which the sensory nervous system, through the actions of potent vasodilator neuropeptides, regulates cardiovascular function in both the normal state and in the pathophysiology of hypertension. The animal models of acquired hypertension studied were deoxycorticosterone-salt (DOC-salt), subtotal nephrectomy-salt (SN-sa...
متن کاملInfection-mediated vasoactive peptides modulate cochlear uptake of fluorescent gentamicin.
Inflammatory mediators released during bacterial infection include vasoactive peptides such as histamine and serotonin, and their serum levels are frequently elevated. These peptides also modulate the vascular permeability of endothelial cells lining the blood-brain and blood-labyrinth barriers (BLB). These peptides may also modulate the permeability of the BLB to ototoxic aminoglycoside antibi...
متن کاملRegulation of Dopamine Uptake by Vasoactive Peptides in the Kidney
Considering the key role of renal dopamine in tubular sodium handling, we hypothesized that c-type natriuretic peptide (CNP) and Ang-(1-7) may regulate renal dopamine availability in tubular cells, contributing to Na(+), K(+)-ATPase inhibition. Present results show that CNP did not affect either (3)H-dopamine uptake in renal tissue or Na(+), K(+)-ATPase activity; meanwhile, Ang-(1-7) was able t...
