Localization of substance P, CGRP, VIP, neuropeptide Y, and somatostatin immunoreactive nerve fibers in the carotid labyrinths of some amphibian species.
T Kusakabe,P Anglade,S. Tsuji +2 more
TL;DR: The results suggest that the vascular regulatory function, which is one of the possible functions of the carotid labyrinth, is controlled by the peptidergic mechanisms in addition to regulation through intimate apposition of glomus and smooth muscle cells (g-s connection).
Journal ArticleDOI
Ultrastructure of the glomus cells in the carotid body of chronically hypoxic rats: with special reference to the similarity of amphibian glomus cells.
TL;DR: The ultrastructural characteristics of the glomus cells in the rat carotid body exposed to extremely long‐term hypoxia were investigated and may facilitate both uptake of oxygen from blood and release of catecholamine into the blood.
Journal ArticleDOI
Carotid labyrinth of amphibians.
TL;DR: The three‐dimensional fine structure of vascular corrosion casts suggests that the amphibian carotid labyrinth has the appropriate architecture for controlling vascular tone and the findings throughout metamorphosis reveal that the vascular regulatory function begins at an early stage of metamorphotic.
Journal ArticleDOI
Coexistence of substance P, neuropeptide Y, VIP, and CGRP in the nerve fibers of the carotid labyrinth of the bullfrog, Rana catesbeiana: a double-labelling immunofluorescence study in combination with alternate consecutive sections.
TL;DR: The combination of the double immunofluorescence technique and alternate consecutive sections demonstrated the possible coexistence of SP, VIP, NPY, and CGRP in most nerve fibers in the intervascular stroma of the carotid labyrinth of the bull-frog, Rana catesbeiana.

Coexistence of substance P and calcitonin gene-related peptide in the nerve fibers of the carotid labyrinth of the bullfrog,Rana catesbeiana

TL;DR: The results suggest that the vascular regulatory function, which is one of the possible functions of the carotid labyrinth, may be controlled in part by the interaction of SP and CGRP.
