Fig. 6. Chronic antioxidant treatment suppresses synaptic terminal degeneration in sdhA mutant R cells.

Cross sections of the lamina neuropil (A-H) or retinas (A, E, I) from 5 day old wild-type flies grown on food containing 200 μg/mL α tocopherol, (B, F, J) 5 day old sdhA¹¹¹⁰ mutant flies treated with vehicle alone. or 5 day old (C, G, K) sdhA¹¹¹⁰ and (D, H, L) sdhA¹⁴⁰⁴ mutants treated with 200 μg/mL α tocopherol. . Laminas are stained (A-D) for R cells (green) and CSP (magenta), and (E-F) the presynaptic assembly molecule, bruchpilot (green) and mitochondrial complex V (magenta). Insets show single cartridges (A-H) or ommatidia (I-L).
