Abstract
Using the indirect immunofluorescence technique of Coons and collaborators, neurons containing substance P-, enkephalin-, vasoactive intestinal polypeptide (VIP) – and somatostatin-like immuno-reactivity have been identified in the peripheral nervous system. They have a widespread distribution, particulary in the gastrointestinal and urinary tracts. Whereas part of these peptide containing fibres may belong to sensory neurons, the majority seem to have their origin in peripheral autonomic ganglia, indicating a complex built up of the autonomic nervous system. There is evidence that some noradrenergic neurons contain somatostatin, which may suggest that one neuron can synthesize and store two transmitters. The significance of such neurons, as well as of peripheral peptide neurons in general, remains to be elucidated.Keywords
