肾素原受体参与肾脏对体液与电解质的调节素原受体参与肾脏对体液与电解质的调节
Zhongshan Daxue xuebao. Yixue kexue ban, 2017 最初的研究发现肾素原受体（PRR）作为肾素与肾素原的特异性受体，参与对肾素-血管紧张素系统（RAS）活性的调节。然而，最新的证据揭示PRR功能的多样性，PRR可以发挥RAS依赖性与非依赖性的作用。PRR可以被furin或 ADAM19切割，产生两个功能性片段，一是28 ku可溶性PRR受体（sPRR），另一个是M8.9，后者是vacuolar H+-ATPase的一个亚型，负责H+转运。近些年的研究证明，PRR参与了许多的生理与病理生理过程的调节。比如，PRR通过调节集合管水通道-2（AQP2 ...
