Expression patterns of the GAL4 drivers. A, Expression pattern of D42-GAL4 driving UAS-mCD8::GFP expression. Signal is enhanced with GFP antibody. B, Expression pattern of OK6-GAL4 driving UAS-mCD8::GFP expression; signal is enhanced with GFP antibody. C, Expression of R75C05-GAL4 driving UAS-mCD8::GFP; signal is enhanced with GFP antibody. D, Expression of R75C05-GAL4 driving UAS-mCD8::GFP in the tbph mutant background (TBPHΔ). Ten larvae were visualized for each construct. Scale bars, 50 μm.
