Cardiovascular and renal pathologies are frequently associated with an activated
renin-angiotensin-system (RAS) and increased levels of its main effector and
vasoconstrictor hormone angiotensin II (Ang II). Angiotensin-converting-enzyme-2
(ACE2) has been described as a crucial enzymatic player in shifting the RAS
towards its so-called alternative vasodilative and reno-protective axis by
enzymatically converting Ang II to angiotensin-(1-7) (Ang-(1-7)). Yet, the
relative contribution of ACE2 to Ang-(1-7) formation in vivo has not been
elucidated. Mass spectrometry based quantification of angiotensin metabolites in
the kidney and plasma of ACE2 KO mice surprisingly revealed an increase in
Ang-(1-7), suggesting additional pathways to be responsible for alternative RAS
activation in vivo. Following assessment of angiotensin metabolism in kidney
homogenates, we identified neprilysin (NEP) to be a major source of renal
Ang-(1-7) in mice and humans. These findings were supported by MALDI imaging,
showing NEP mediated Ang-(1-7) formation in whole kidney cryo-sections in mice.
Finally, pharmacologic inhibition of NEP resulted in strongly decreased Ang-(1-7)
levels in murine kidneys. This unexpected new role of NEP may have implications
for the combination therapy with NEP-inhibitors and
angiotensin-receptor-blockade, which has been shown being a promising therapeutic
approach for heart failure therapy.
