Fig. 1

Graf promoter-driven expression of mCD8-GFP in adult MB neurons. a Schematic representation of the Drosophila adult MB (left side only) showing the axonal projections of α/β, α′/β′, and γ neurons. b Confocal z-projections of a wild-type adult brain expressing UAS-mCD8-GFP driven by a Graf promotor-GAL4 fusion (Graf-GAL4) and stained with anti-GFP and anti-FasII antibodies. Bottom panels show high magnification views of areas marked by white boxes to highlight high expression of GFP in FasII-positive MB α/β axons. Note that the Graf promotor is additionally active in the antennal lobe (AL) and subesophageal ganglion (SEG). EB, ellipsoid body. Arrowheads indicate the brain midline. Scale bars, 100 μm
