TkR99Df02797/TkR99Df02797 early third instar larvae do not have significantly different baseline thermal nociception (uninjured larval responses to thermal probes at 45[o] or 48[o]C) compared to controls. 24 hours after UV-induced nociceptive sensitization, early third instar TkR99Df02797/TkR99Df02797, TkR99Df02797/TkR99DMB09356 or TkR99Df02797/Df(3R)Exel6213 larvae show significant reduction of thermal allodynia (withdrawal responses to a sub-threshold 38[o]C probe) compared to wild type or heterozygote larvae.
TkR99Df02797/TkR99DMB09356 third instar larval fillets do not show a UV-induced increase in action potential firing rate at higher temperatures (36-39[o]C) in class IV neurons, as seen in controls.
TkR99Df02797/TkR99DMB09356 is rescued by Scer\GAL4ppk.1.9/TkR99DUAS.EGFP
Expression of TkR99DScer\UAS.T:Avic\GFP-EGFP driven by Scer\GAL4ppk.1.9 significantly rescues the reduction of thermal allodynia (withdrawal responses to a sub-threshold 38[o]C probe after UV-induced nociceptive sensitization) seen in early third instar TkR99Df02797/TkR99DMB09356 larvae. TkR99DScer\UAS.T:Avic\GFP-EGFP driven by Scer\GAL4ppk.1.9 significantly restores a UV-induced increase in action potential firing rate in class IV neurons at higher temperatures (36-39[o]C) in third instar TkR99Df02797/TkR99DMB09356 larval fillets.
