As an M.D.–Ph.D. student, I was fortunate to have worked in the laboratories of Earl Sutherland and Theodore Rall shortly after their discovery of cyclic adenosine monophosphate (AMP) in 1957 as a second messenger that mediates the glycogenolytic effects of epinephrine and glucagon.1 My assignment was to examine the effects of catecholamines on cyclic AMP synthesis and determine whether these effects were mediated through the beta or alpha adrenergic receptor. This was actually a straightforward and simple student assignment.2 I also found that choline esters such as acetylcholine, acting by transduction at the muscarinic receptor, inhibited adenylyl cyclase activity.2 This . . .
