Figure 4: Draper is required for nucleation of glial HttQ25 aggregation by neuronal HttQ91 aggregates.
From: Prion-like transmission of neuronal huntingtin aggregates to phagocytic glia in the Drosophila brain

(a) Draper is essential for transfer of HttQ91 aggregates from DA1 ORN axons to the glial cytoplasm. Maximum intensity Z-projections of the DA1 glomerulus from 7-day-old adult fly brains expressing HttQ91-mCherry in DA1 ORNs and HttQ25-YFP in glia, either without (control) or with depletion of Draper expression using two independent RNAi lines (DraperRNAi1 and DraperRNAi2) or the drprΔ5 null mutation (draper−/−). Scale bars, 5 μm. (b) Quantification of the number of induced HttQ25 aggregates detected in the antennal lobe of 7-day-old adult flies as in a (n≥8, ±s.e.m., ***P<0.0005, one-way analysis of variance followed by Tukey’s post hoc test).
