Fig. 15From: Expression of vasopressin and its receptors in migraine-related regions in CNS and the trigeminal system: influence of sexImmunohistochemistry of OT and OTR expression in TG from male and female rat. a OT immunoreactivity was located in the SGCs (arrowhead) and in the cytoplasm of neurons (arrow). Of all neurons, 35% in males and 52% in females showed OT immunoreactivity. b OTR (32% in males. 45% in females) was expressed in the neuronal cytoplasm (arrows) and in thick nerve fiber (Aδ –fibers) (arrowheads)Back to article page
