New research at Washington University School of Medicine in St. Louis helps illuminate a surprising mind-body connection.
In mice, the researchers found that immune cells surrounding the brain produce a molecule that is then absorbed by neurons in the brain, where it appears to be necessary for normal behavior.
The findings, published Sept. 14 in Nature Immunology, indicate that elements of the immune system affect both mind and body, and that the immune molecule IL-17 may be a key link between the two.
