To discover the supply of active Hh, we attempted tissue-specific knockdowns. However, none on the UAS-HhRNAiIm et al. eLife 2015;four:e10735.

(A) “Genetic” allodynia induced by ectopic Hh overexpression in many tissues. Tissue-specific Gal4 drivers, UAS controls and combinations are indicated. The Gal4 drivers employed are ppk-Gal4 (class IV sensory neuron), A58-Gal4 (epidermis), and Myosin1A-Gal4 (gut). (B) Schematic of class IV neuron isolation and immunostaining. (C) Isolated class IV neurons stained with anti-Hh. mCD8-GFP (green in merge); anti-Hh (magenta in merge). (D) Variety of Hh punctae in isolated class IV neurons from genotypes/conditions in (C). Punctae per image are plotted as individual points. Black bar; mean gray bracket; SEM. Statistical significance was determined by One-way ANOVA test followed by various comparisons with Tukey correction. (E) UV-induced thermal allodynia upon UAS-dispRNAi expression with relevant controls. (F) Suppression of “genetic” allodynia by co-expression of UAS-dispRNAi in class IV neurons. Genetic allodynia situations had been induced by Hh overexpression, PtcDN expression, or DTKR-GFP overexpression.

Genetic allodynia in the absence of tissue injury upon overexpression of TNF in class IV neurons. DOI: 10.7554/eLife.10735.transgenes we tested had been effective at inducing wing patterning phenotypes in the wing imaginal disc (Figure 6–figure supplement 1) nor exhibited defects in thermal allodynia (Figure 6–figure supplement two). Hence, we asked if tissue-specific overexpression of UAS-Hh in a selection of tissues could induce ectopic thermal allodynia in the absence of UV. Amongst class IV neurons, epidermis, and gut, overexpression of Hh only in class IV neurons resulted in ectopic sensitization (Figure 6A). This suggests that the class IV neurons themselves are possible Hh-producing cells. These gain-of-function outcome.
