Immunohistochemistry of AVP, V1aR, V1bR and V2R in TG from male and female rat. AVP immunoreactivity was located in neuronal cytoplasm (arrow) and in SGCs (arrowhead) and of all neurons, 36% were positive for AVP in males and 37% in females. In males, 76% of all neurons were V1aR immunoreactive and 75% V1bR immunoreactive. In females, 86% of all neurons were positive for V1aR and 84% of all neurons were positive for V1bR. V1aR and V1bR were located in neuronal cytoplasm (arrow) and in fibers (arrowheads). V2R immunoreactivity was expressed mostly in the SGCs (arrowhead) and a fewer in the neuronal cytoplasm (arrow)
