1 Adenosine constricts the afferent arteriole via A1 receptors and dilates (to a lesser degree) efferent arterioles via A2 receptors. 2  This acts to decrease the glomerular filtrate rate. 3  Adenosine also inhibits renin release in juxtaglomerular cells via A1 receptors on JG cells using a Gi pathway.
