The coexistence and release of bovine pancreatic polypeptide-like immunoreactivity from noradrenergic superior cervical ganglia neurons.

Abstract

The coexistence of bovine pancreatic polypeptide-like (BPP) immunoreactivity within the cell bodies and axons of the superior cervical ganglia (SCG) was studied. Adjacent sections stained by the indirect immunofluorescence technique for either BPP or dopamine-beta-hydroxylase (DBH) revealed that virtually all (90-95%) SCG cells contained DBH and a subpopulation (30-50%) also contained BPP. Ligation of the pre- and postganglionic nerves of the SCG demonstrated BPP-positive fibers emanating from the SCG via both axonal trunks. BPP-containing fibers were also observed entering the SCG via the preganglionic nerve. The peptide was co-released with catecholamine by electrical stimulation of the preganglionic cervical sympathetic nerve trunk, but was not effected by reserpine. The extensive distribution and unique coexistence of a PP-like peptide with peripheral sympathetic nerves suggests a neuromodulatory role in autonomic functions.
