A second control element is sympathetic nervous discharge to the kidney, which stimulates renin secretion through Î²-adrenergic receptors on the JGCs (). Increased renin secretion in response to Î²-adreneroceptor stimulation is mediated via the formation of cAMP. second control element is sympathetic nervous discharge to the kidney, which stimulates renin secretion through Î²-adrenergic receptors on the JGCs ().
