Outline of Final Research Achievements |
In this study, I studied microbiota-brain-gut axis via immune system in chronic mild stress. I found that immune system and gut microbiota were changed in PAWW stress mice. Finally, I selected IL6 and IL10 to be bio-marker of PAWW stress mice. I developed new and stable RAW 264.7 derived dual-color IL-6/gapdh and IL-10/gapdh reporters. This assay allowed us to easily determine relative IL-6 and IL-10 levels with 96-well plate within one step. I evaluated the relative IL-6 and IL-10 levels in the LPS-induced stable cells testing 52 natural products by real-time bioluminescence monitoring. By this screening assay, I found that 1`S-1`-acetoxychavicol from greater galangal could reduce IL-6 level and increase IL-10 level. Finally, I can suggest that these stable cells by real-time monitoring could serve as a screening assay for anti-inflammatory activity and may be used to discover new drugs against stress.

Academic Significance and Societal Importance of the Research Achievements |
In the future, we may reduce animal experiments by this assay for screening compounds or drugs. However, this finding is meaningful not only for academics, but it may lead the people concern that stress could make immune system change, and cause the disease, and herb to reboot immune system.
