VGLUT1 colocalizes with the presynaptic protein SV2. Confocal fluorescence micrographs of a vertical section of rat retina are shown. A, D, VGLUT1; B, E, SV2; C, F, overlay of VGLUT1 and SV2.Yellow indicates colocalization. Nearly complete colocalization occurs in the OPL, indicating expression of VGLUT1 in photoreceptor terminals. In the IPL, SV2 immunoreactivity is more widespread than VGLUT1, suggesting that VGLUT1 is expressed in a subset of synapses in the IPL. Scale bars: A–C, 15 μm;D–F, 20 μm.
