Immunohistochemistry of CGRP and RAMP1 expression in TG from male and female rat. a CGRP was located in the cytoplasm of neurons (arrow) and in C-fibers (arrowhead). 48% in male and 42% in female of the total number of neurons showed positive CGRP immunoreactivity. b 22% in males and 41% in females of all neurons was expressed RAMP1 which was located in the neuronal cytoplasm (arrows) and in thick nerve fiber (Aδ –fibers) (arrowheads)
