It seems that scientists are about to develop a "stress vaccine" – and we are definitely intrigued.
A study conducted in 2018 revealed that a soil bacterium called Mycobacterium vaccae (Mr. vaccae) reduces stressful reactions in the mouse.
The research team, led by integrative physiology professor Christopher Lowry of the University of Colorado at Boulder, injected the bacteria into the mice before exposing them to stressful events.
In the short term, the "vaccine" prevented a "PTSD" syndrome. This also reduced the stress reactions thereafter.
Last month, Lowry and his team released a new study. He identified an anti-inflammatory fat in the bacteria that could be responsible for its effects.
The team chemically isolated and synthesized the fatty acid, which allowed him to see how he interacted with the immune cells.
Speaking of the new study, Lowry said CU Boulder today:
"The idea is that since humans have moved away from farms and agriculture and hunter-gatherers to settle in cities, we have lost contact with organizations serving regulate our immune system and suppress inappropriate inflammation.
"This put us at a higher risk of inflammatory disease and stress-related psychiatric disorders."
However, Lowry noted that the vaccine was still far from ready.
He said at Denver Post that the vaccine will be available in 10 to 15 years.
He said:
"The power of nature continues to amaze and surprise us as scientists and we look forward to learning more."
