Dopamine increases adenosine 3',5'-monophosphate (cyclic AMP) but not guanosine 3',5'-monophosphate (cyclic GMP) in slices of bovine sympathetic ganglion; this increase is localized to the postganglionic neurons. Conversely, acetylcholine increases cyclic GMP but not cycle AMP in the ganglion; this increase also occurs within postganglionic neurons. Thus, different neurotransmitters can selectively alter cyclic nucleotide levels within the same neuronal population.
