Abstract

This presentation will cover recent advances relating the role of the sympathetic nervous system in the regulation of the salt sensitivity of blood pressure. Recent studies from our laboratory have elucidated the previously unknown role of PVN specific Galphai2 signal transduction in the prevention of the development of the salt sensitivity of blood pressure. We will discuss these findings and their potential translational relevance. Highlighting the role(s) of the renal sympathetic nerves in the modulation of sodium reabsorption and long-term blood pressure regulation we will highlight recent advances in the role(s) of the afferent renal nerves in the salt sensitivity of blood pressure and how increased renal sympathetic outflow influences the expression and activity of the renal sodium chloride cotransporter.
