Objective Aims to delineate the distribution profile of three isoforms of vesicular glutamate transporter (VGluT), viz. VGluT1-3, and their cellular localization within vestibular nuclear complex (VNC). Methods Brain sections from normal Sprague-Dawley rats were processed immunohistochemically for VGluT detection, employing avidin-biotinylated peroxidase complex method with 3-3'-diaminobenzidine (DAB) as chromogen. Results The whole VNC expressed all of the three transporters that were observed to be localized to the fiber endings. Compared with VGluT1 and VGluT3, VGluT2 demonstrated a relatively homogeneous distribution, with much higher density in VNC. VGluT3 displayed the highest density in lateral vestibular nucleus and group X, contrasting with the sparse immunostained puncta within vestibular medial and inferior nuclei. Conclusion Glutamtatergic pathways participate in the processing of vestibular signals within VNC mainly through the re-uptake of glutamate into synaptic vesicles by VGluT1 and 2, whereas VGluT3 may play a similar role mainly in areas other than medial and inferior nuclei of VNC.
