The intrarenal dopamine system is important for signaling and natriuresis, and
significant dysfunction is associated with hypertension and kidney disease in ex
vivo studies. Dopamine receptors also modulate and are modulated by the
renin-angiotensin-aldosterone system. Here, we show the first in vivo measurement
of D1-like receptors in the renal cortex of Sprague-Dawley rat and Papio anubis
baboon using [(11)C]NNC 112, a positron emission tomography radioligand for
D1-like receptors. In addition, we show a D1-like binding potential response to
angiotensin II blockade in rats using losartan. Demonstration of self-saturable
binding in the rat as well as specific and saturable binding in Papio anubis
validate the use of [(11)C]NNC 112 in the first in vivo measurement of renal
dopamine D1-like receptors. Furthermore, [(11)C]NNC 112 is a radioligand tool
already validated for use in probing human central nervous system (CNS) D1-like
receptors. Our work demonstrates specific and saturable non-CNS binding in higher
animals and the ability to quantify physiological response to drug treatment and
provides a clear path to extend use of [(11)C]NNC 112 to study renal dopamine in
humans.
