Steroid hormones organize many aspects of development, including that of the nervous system. Steroids also play neuromodulatory and other activational roles, including regulation of sensitivity to painful stimuli in mammals. In Drosophila, ecdysteroids are the only steroid hormones, and therefore the fly represents a simplified model system in which to explore mechanisms of steroid neuromodulation of nociception. In this report, we present evidence that ecdysteroids, acting through two isoforms of their nuclear ecdysone receptor (EcR), modulate sensitivity to noxious thermal and mechanical stimuli in the fly larva. We show that EcRA and EcRB1 are expressed by third instar larvae in …

Traditional drug development efforts to diminish the problem of chronic pain rely heavily on pain-evoked assays that can yield false positives, leading to confounding assessments of novel drugs. To avoid this, we are looking at burrowing as a novel readout assessment of analgesic efficacy. Preliminary data shows that induction of post-surgical pain reduces this innate behavior by about 35%. In attempt to increase this number, we tested a variety of additional parameters. Blue pads, placed at the bottom of each chamber in order to reduce the sound made when gravel is displaced, increased baseline amounts roughly 40%. Conversely, neither sex …
