Figure 5. Colocalization of Dexras1, neuronal nitric oxide synthase (nNOS), and C-terminal PSD95/DLG/ZO-1 ligand of neuronal nitric oxide synthase (CAPON) after light exposure. Immunofluorescence was performed to observe Dexras1 colocalization with nNOS and CAPON in the retina at 1 day after light exposure. A-C: nNOS immunoreactivity was colocalized in Dexras1-positive cells in the retina. D-F: nNOS immunoreactivity was colocalized in CAPON-positive cells in the retina. G-I: Dexras1 immunoreactivity was colocalized in CAPON-positive cells in the retina. C, F, I: Merged images. Magnification, 400×. Abbreviations: GCL represents ganglion cell layer; INL represents inner nuclear layer; ONL represents outer nuclear layer.
