Fig. 6From: C-fibers may modulate adjacent Aδ-fibers through axon-axon CGRP signaling at nodes of Ranvier in the trigeminal systemExpression of RAMP1 and CGRP in relation to the node of Ranvier in rat dura mater spreads. RAMP1 (a) and CGRP (b) had similar localization at the node of Ranvier in the rat dura mater as for the TG. Top; CASPR (green, arrowhead), RAMP1 (red, arrow). Bottom; CASPR (green, arrowhead), CGRP (red, arrow)Back to article page
