| Outline of Final Research Achievements |
The innate immune system is the first line of defense encountered by invading pathogens. We have found that immune challenge leads to change host glycosylation, which involved in full activation of immune response. Our aim in this study was to reveal the mechanism of the host glycan change by immune challenge.
In this study, we found that glucosaminoglycan (GAG) regulates immune activity. GAG suppresses hyper-activation of the Toll pathway in the steady state. Interestingly, pathogen infection reduces the expression of a GAG synthesizing enzyme to enhance immune responses. These results indicate that GAG plays an important role in both suppression of runaway inflammation and enhancement of immune responses.
