Research Abstract

We have revealed that Gyc76C, a receptor-type guanylate cyclase, mediates innate immunity. In this study, we sought to identify a ligand for Gyc76C.
We found that Drosophila larval extract has an activity that induces the expression of antimicrobial peptides in Drosophila cell line. The activity was purified to homogeneity and the amino acid sequence was determined, resulting in theidentification of a new protein that activates innate immune system in Drosophila. Further analysis should be done to validate that whether the identified protein would be a ligand for Gyc76C.
