Immunohistochemial analysis for spinal GABA transporters, GAT-1 and GAT-3 among the naïve, allodynic and non-allodynic animals 2 weeks following neuropathic surgery. Behavioral differences among the groups are illustrated in Fig. 5A. (A) Microphotographs illustrating distribution of GAT-1- and GAT-3-ir in the S1 spinal segment ipsilateral to nerve injury. Scale bar=100 µm. (B) Relative staining intensities of GAT-1- and GAT-3 as compared to the naïve animals. Immunoreactivities in both the allodynic and non-allodynic groups are not different from those of the naïve group.
