Fig. 2From: C-fibers may modulate adjacent Aδ-fibers through axon-axon CGRP signaling at nodes of Ranvier in the trigeminal systemCGRP receptor localization at the paranodal region in the TGImmunohistochemical localization of the CGRP receptor protein RAMP1 (red, arrow) in myelinated axons of the trigeminal ganglion labeled with CASPR (green, arrowhead), a marker for nodes of Ranvier. Merged images reveal co-localization (yellow) of RAMP1 with CASPR at the nodesBack to article page
