Fig. 7. The nuclear accumulation of Dorsal and Dif is impaired in nup214 mutants. All panels show fat bodies of wild-type (wt) and nup214 mutant larvae, before (not challenged) and after bacterial infection (bact. challenged) stained with specific antibodies for Dorsal, Dif, ß-galactosidase for cecropin-lacZ or GFP for drosomycin-GFP expression. Nuclei are visualized with DAPI (blue). Bars, 35 µm.
