PSD95 immunolabeling in the degus retina. (A,A’) Juvenile degus, (B,B’) Young degus, (C,C’) adult degus, (D,D’) aged adults. (E) Quantification of % area occupied by PSD95 labeling in the entire retinal image. Intense labeling in the outer segment seen in (C,C’) is judged to be unspecific autofluorescence. PSD95, post-synaptic density protein 95; OLM, outer limiting membrane; ONL, outer nuclear layer; OPL, outer plexiform layer; ILM, inner limiting membrane; INL, inner nuclear layer; IPL, inner plexiform layer; GCL, ganglion cell layer; NFL, nerve fiber layer. Scale bar = 20 μm. Statistical analysis was completed by one way ANOVA. Data are expressed as mean ± SEM (n = 6). Significant values are indicated with asterisks: *p < 0.05; **p < 0.01; ***p < 0.001.
