Figure 4From: Adenovector GAD65 gene delivery into the rat trigeminal ganglion produces orofacial analgesia Sensory neurons of the trigeminal ganglion express both GABA A and GABA B receptors. GABAA receptor immunostaining of ganglion neurons is membrane associated (A1, red, arrows) while GABAB immunostaining is cytoplasmic (A2) The combined image (A3) shows some neurons are double labelled for GABAA receptor and GABAB receptor (A3, arrows).
