Research Abstract

Innate immunity is the first line of defense against infectious microorganisms, and the basic mechanisms of pathogen recognition and activation of the response are evolutionary conserved. In Mammals, the innate immune response is required in combination with antigen-specific recognition for the activation of the adaptive immunity. Therefore, innate immunity is one of the pharmaceutical targets for the development of immune regulators. In this study, for the purpose of pharmaceutical screening, we established an in vitro culture based on innate immune response of Drosophila. The in vitro system is capable of measuring the lipopolysacharide (LPS)-dependent activation of the imd pathway that shows similarity to tumor necrosis factor (TNF) signaling pathway in mammals. From the screening with about 1,000 samples, we found that a cyclopentanediol derivative inhibits the LPS-dependent activation of the imd pathway. The cyclopentanediol derivative found to inhibit intracellular signaling cascade of the imd pathway from an adaptor protein called imd to Relish transcriptional factor. Because the intracellular signaling cascade of the imd pathway shows similarity to tumor necrosis factor (TNF) signaling pathway in mammals, we investigated whether the cyclopentanediol derivative inhibits human TNF signaling pathway, one of the innate immune response in human. We found that the cyclopentanediol derivative inhibit TNF-dependent induction of chemokines in human umbilical vein endothelial cells (HUVEC). These results suggest that the newly established system is useful for pharmaceutical screening in identification of compounds which act on innate immunity.
