title: Minireview. Evidence that dopamine is a neurotransmitter in peripheral tissues.
abstract: In the CNS, dopamine (DA) is a recognized neurotransmitter as well as a precursor for norepinephrine (NE) and epinephrine (EPI). In contrast to the CNS, DA has been assumed to be only a precursor in peripheral tissues. There is now, however, considerable evidence to support the hypothesis that it may function as a neurotransmitter and/or cotransmitter in peripheral tissues in addition to being a precursor. In this minireview we summarize evidence supporting the view that DA plays a role of its own in peripheral neurotransmission.
