Figure 5. Goro neurons lacking CCKLR-17D1 show sensitized responses to noxious heat.
(A) Representative still images showing thermal activation of Goro neurons in the controls (top, yw/Y; R69E06-GAL4 UAS-GCaMP6m/+) and CCKLR-17D1Δ1 mutants (bottom, CCKLR-17D1Δ1/Y; R69E06-GAL4 UAS-GCaMP6m/+). See also Videos 1 and 2. (B) Average percent increase of GCaMP6m fluorescence intensity relative to the baseline (ΔF/F0) during heat ramp stimulations in controls (n=15) and CCKLR-17D1Δ1 (n=15). * p<0.05, ** p<0.01 Mann-Whitney’s U-test. (C) Basal GCaMP6m signal levels (F0) in controls (n=15) and CCKLR-17D1Δ1 mutants (n=15). p>0.6 Mann-Whitney’s U-test. (D) Representative stills showing thermal activation of the controls (top, R69E06-GAL4 UAS-GCaMP6m x yv; attp2) and Goro neurons expressing CCKLR-17D1 RNAi (bottom, R69E06-GAL4 UAS-GCaMP6m x yv; JF02644). See also Videos 3 and 4. (E) Average percent increase of GCaMP6m fluorescence intensity relative to the baseline (ΔF/F0) during heat ramp stimulations in controls (n=15) and CCKLR-17D1 RNAi (n=16). * p<0.05 Mann-Whitney’s U-test. (F) Basal GCaMP6m levels (F0) in controls (n=15) and CCKLR-17D1 RNAi (n=16). p>0.6 Mann–Whitney’s U-test. Error bars represent standard error. All box plots show median (middle line) and 25th to 75th percentiles with whiskers indicating the smallest to the largest data points. All scale bars represent 20 µm.
