Researchers report a cleaner living environment may not detrimentally impact a child's developing immune system, as current theories suggest.
10(Z)-hexadecenoic acid, a fatty acid found in the soil based bacterium Mycobacterium vaccae, interacts with immune cells to inhibit pathways that drive inflammation and increases resilience to stress. Researchers say the findings could bring us one step closer to developing a microbe-based "stress vaccine".
