Abstract |
Nociceptive sensitization is an increase in pain perception in response to stimulus. Following brief irradiation of Drosophila larvae with UV, nociceptive sensitization occurs in class IV multiple dendritic (mdIV) neurons, which are polymodal sensory nociceptors. Diverse signaling pathways have been identified that mediate nociceptive sensitization in mdIV neurons, including TNF, Hedgehog, BMP, and Tachykinin, yet the underlying mechanisms are not completely understood. Here we report that duox heterozygous mutant larvae, which have normal basal nociception, exhibit an attenuated hypersensitivity response to heat and mechanical force following UV irradiation. Employing the ppk-Gal4 line, which is exclusively expressed in mdIV neurons, we further show that silencing duox in mdIV neurons attenuates UV-induced sensitization. Our findings reveal a novel role for duox in nociceptive sensitization of Drosophila larvae, and will enhance our understanding of the mechanisms underlying this process in Drosophila sensory neurons. |
