For the first time, clarifying a mechanism by which short sleep disrupts intestinal microbiota and the metabolites, in relation to lower α-defensin.

Study clarified that shorter sleep time is associate with lower α-defensin secretion and further induces disruption of the intestinal microbiota along with low production of short-chain fatty acids, showing previously unknown relationship between the intestine and brain.

 

This research topic is related to the sustainable development goals (SDGs);
3. GOOD HEALTH AND WELL-BEING
8. DECENT WORK AND ECONOMIC GROWTH
