Abstract

Double staining immunohistochemistry was used to investigate the origin and projection of nerves with substance P (SP) immunoreactivity (-IR) in the walls of the major cerebral arteries in two microchiropteranspecies. In the greater horseshoe bat, most of the cerebral perivascular nerves with SP-IR did not exhibit calcitonin gene-related peptide (CGRP)-IR, but emitted bright immunofluorescence for vasoactive intestinal polypeptide (VIP). In this species, a large number of cell bodieswith both SP- and VIP-IR were observed in many cranial ganglia along various branches of the facial and glossopharyngeal nerves. There wereno cell bodies immunoreactive for either SP and VIP in the two sensory (trigeminal and upper cervical dorsal root), two sympathetic (superior cervical and stellate), or two vagal (superior and jugular) ganglia. In addition, several thick fiber bundles with both SP- and VIP-IR were present in the wall of the cerebral carotid artery, and descended progressively reaching as far as the middle part of the basilar artery (BA). These and other findings suggest that SP-immunoreactive nerves with VIP-IF but not CGRP-IR, which contribute to the rich innervation of the vertebrobasilar system in the greater horseshoe bat, originate from neurons with the same combination of peptide-IR in the major or local facial or glossopharyngeal parasympathetic ganglia, and enter the cranial cavity along the internal carotid artery. In the bent-winged bat, however, cerebral perivascular SP-immunoreactive nerves, as well as SP-immunoreactive neurons within the trigeminal and upper cervical dorsal root ganglia (uCDRG), showed neither CGRP-IR nor VIP-IR, and were mostly confined to the caudal BA and the vertebral artery (VA). These observations, in addition to the projection of this nerve type to the BA via the VA as fiber bundles, or through the meninges, indicate that the principal source of the cerebrovascular SP-immunoreactive innervation in this species is the uCDRG.
