Allatostatin C modulates nociception and immunity in Drosophila.

ABSTRACT: Bacterial induced inflammatory responses cause pain through direct activation of nociceptive neurons, and the ablation of these neurons leads to increased immune infiltration. In this study, we investigated nociceptive-immune interactions in Drosophila and the role these interactions play during pathogenic bacterial infection. After bacterial infection, we found robust upregulation of ligand-gated ion channels and allatostatin receptors involved in nociception, which potentially leads to hyperalgesia. We further found that Allatostatin-C Receptor 2 (AstC-R2) plays a crucial role in host survival during infection with the pathogenic bacterium Photorhabdus luminescens. Upon examination of immune signaling in AstC-R2 deficient mutants, we demonstrated that Allatostatin-C Receptor 2 specifical
