Vallon V, Richter K, Heyne N, Osswald H. Effect of intratubular application of angiotensin 1-7 on nephron function. Kidney Blood Press Res. 1997;20:233-9 pubmed
..Intratubular Ang 1-7 at a concentration of 10(-8) M appears to increase reabsorption in Henle's loop by an AT1 angiotensin II receptor-mediated mechanism, the physiological relevance of which remains to be established. ..

..NHE3 appears not to significantly contribute to fluid or Na(+) reabsorption in the loop of Henle (including the S3 segment of proximal tubule) or macula densa control of nephron filtration...
