Fig. 5From: Estrogen receptors α, β and GPER in the CNS and trigeminal system - molecular and functional aspectsERα receptor distribution in the TG. a The neuronal nuclei of the TG express ERα receptor. The montage discloses the neuronal nuclei staining, arrow heads point at a negative nucleus of the glial cells, and arrows at a positive neuronal nucleus. b In the trigeminal nerve, immunoreactivity was found in the nerve fibers. Insert: Perpendicular cut nerve fibers displays an inner immunoreactive fiber (arrow). Outside of the fiber, the myelin sheet showed no immunoreactivityBack to article page
