Summary: 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”.

Thirty years after scientists coined the term “hygiene hypothesis” to suggest that increased exposure to microorganisms could benefit health, University of Colorado Boulder researchers have identified an anti-inflammatory fat in a soil-dwelling bacterium that may be responsible.

The discovery, published Monday in the journal Psychopharmacology, may at least partly explain how the bacterium, Mycobacterium vaccae, quells stress-related disorders. It also brings the researchers one step closer to developing a microbe-based “stress vaccine.”
