Long-term stimulatory effect of neuropeptide-Y on the growth and steroidogenic capacity of rat adrenal zona glomerulosa
Neuropeptides.
1988 Apr.
Abstract
A prolonged infusion with neuropeptide-Y (NPY) caused a notable hypertrophy of the adrenal zona glomerulosa and its parenchymal cells in rats whose hypothalamo-hypophyseal axis and renin-angiotensin system were pharmacologically interrupted. Zona glomerulosa hypertrophy was associated with a significant rise in both basal and stimulated plasma levels of aldosterone. Zona fasciculata cells and the blood concentration of corticosterone were not affected. These findings suggest that NPY is specifically involved in the stimulation of the growth and steroidogenic capacity of rat adrenal zona glomerulosa.
