title: Neural control of renal tubular solute and water transport.
abstract: The neural control of renal tubular solute and water transport is recognized as an important physiological mechanism in the overall regulation of solute and water homeostasis by the mammalian organism. Recent studies have expanded the understanding of this mechanism concerning the transport of diverse solutes with beginning insight into the precise nature of the cellular transport processes involved. The modulatory roles of both circulating and intrarenal hormonal systems on the responses to alterations in the magnitude of efferent renal sympathetic nerve activity are being understood from the nerve terminal release of neurotransmitter to influences on cellular transport processes which determine the overall effect. When dietary sodium intake is normal or only modestly reduced, intact renal innervation is not essential for normal renal sodium conservation. However, when dietary sodium intake is severely restricted, there is maximum engagement of all mechanisms known to participate in renal sodium conservation and, under these conditions, intact renal innervation is essential for normal renal sodium conservation.
