Adult Drosophila recover functionality after CNS crush injury and this requires glial Drpr. (A) Histograms representing the percentage of injured flies that correspond to each of the three movement categories Worse (red), No change (grey) or Improved (green), compared to T0 (24 h ACI). Functional recovery capacity of control flies (repoGal4 and UAS-drprRNAi alone) compared with drpr knockdown in glia. Chi-square test with two degrees of freedom, ***P<0.0001, **P<0.005. (A′) Histograms represent the percentage of flies corresponding to each category separately. (B) Quantification of the MtN:Brain nc82 mean intensity signal ratio of not recovered and recovered flies 7 days ACI. Unpaired t-test, **P<0.005. Genotypes: tubGal80ts, repoGal4/+, UAS DrprRNAi/+, tubGal80ts, repoGal4>UAS-DrprRNAi (A,A′); wild type (B).
