Certain
types of bacteria in the gut can leverage the immune system to decrease
the severity of stroke, according to new research from Weill Cornell
Medicine. This finding can help mitigate stroke — which is the second
leading cause of death worldwide. In the study, published March 28 in
Nature Medicine, mice received a combination of antibiotics. Two weeks
later, the researcher team — which included collaborators at Memorial
Sloan Kettering Cancer Center — induced the most common type of stroke,
called ischemic stroke, in which an obstructed blood vessel prevents
blood from reaching the brain. Mice treated with antibiotics experienced
a stroke that was about 60 percent smaller than rodents that did not
receive the medication. The microbial environment in the gut directed
the immune cells there to protect the brain, the investigators said,
shielding it from the stroke's full force. The findings suggest that
modifying the microbiotic makeup of the gut can become an innovative
method to prevent stroke. This could be especially useful to high–risk
patients, like those undergoing cardiac surgery or those who have
multiple obstructed blood vessels in the brain.
