Fig 2. αSyn expression in flies induced mild compound eye degeneration.

(A) Light microscopic images of fly eyes showing that there is almost no difference in compound eye morphology among the flies expressing WT and mutant αSyn. Scale bar, 100 μm. (B) SEM images demonstrating eye degeneration, including abnormalities in ommatidial morphology and bristle patterns. However, the extent of degeneration was too mild to detect the difference among the genotypes. Scale bar, 20 μm. Fly genotype: +, GMR-GAL4/Y;;+/+. Other fly genotypes are the same as those in Fig 1B.
