Dopamine-containing small intensely fluorescent cells and sympathetic ganglion function.

This article reviews some of the neuropharmacology of the dopamine (DA)-containing small intensely fluorescent cells of sympathetic ganglia. The major metabolite of DA found in the ganglia is 3,4-dihydroxyphenylacetic acid (DOPAC). DOPAC content appears to be a direct reflection of DA synthesis. DA synthesis can be enhanced by muscarinic agonists and diminished by muscarinic antagonists. Neuroleptic drugs stimulate DA synthesis in the ganglion, which suggests that a local negative neuronal feedback loop might operate within the ganglion. There may be a correlation between deficient DA synthesis in spontaneous hypertensive rats and the development of hypertension. It is possible that some of the peripheral side effects of drugs that act on dopaminergic neurons in the brain might originate from the drugs' action on peripheral dopaminergic neuronal systems such as the sympathetic ganglion.[1]
