title: Hypothesis:presynaptic receptors controlling renin release.
abstract: Presynaptic receptors have recently been identified on nerves supplying vascular smooth muscle. Renin is stored in juxtaglomerular cells in the wall of the afferent glomerular arteriole and the JG cell is probably derived from vascular smooth muscle. Nervous stimuli exert an important influence on release of renin, but the nature of the receptors involved is not agreed. We propose that there are presynaptic receptors associated with the JG apparatus as with vascular muscle and that a mechanism of this sort gives a better account of data on renin release.
