Colocalization of multiple GABA(A) receptor subtypes with gephyrin at postsynaptic sites

The Journal of Comparative Neurology
Marco Sassoè-PognettoJ M Fritschy


Clustering of gamma aminobutyric acid (GABA)(A) receptors to postsynaptic sites requires the presence of both the gamma2 subunit and gephyrin. Here, we analyzed by double-immunofluorescence staining the colocalization of gephyrin and major GABA(A)-receptor subtypes distinguished by the subunits alpha1, alpha2, alpha3, or gamma2 in adult rat brain. By using confocal laser scanning microscopy, GABA(A)-receptor subunit staining revealed brightly stained clusters that were colocalized with gephyrin-positive clusters of similar size and distribution in several brain regions, including cerebellum, hippocampus, thalamus, and olfactory bulb. In addition, a diffuse staining was observed for GABA(A)-receptor subunits in the neuropil, presumably representing extrasynaptic receptors. Overall, only few gephyrin-positive clusters were not colocalized with GABA(A)-receptor subunit clusters. Electron microscopic analysis in cerebellar cortex confirmed the selective postsynaptic localization of gephyrin. High-resolution images (voxel size, 50 x 50 x 150 nm) were restored with an iterative image deconvolution procedure based on a measured point-spread function to analyze the colocalization between GABA(A)-receptor subunits and gephyrin in indivi...Continue Reading
