Nature Immunology published unique research results from the Washington University School of Medicine
As part of the work, scientists have found that immunecells located around the brain produce a molecule that is subsequently absorbed by the neurons in the brain, thereby affecting the brain. According to scientists, this has an impact on the anxious behavior of rodents.
At this stage, scientists believe that the influenceimmune system on the brain may have arisen as part of a survival strategy. In particular, increasing vigilance in rodents promotes their recovery from infection.
“Most likely the immune system and brainco-evolved. Selection of specific molecules for simultaneous immunological and behavioral protection – this is a smart way to protect against infection. This is a good example of how cytokines that primarily evolved to fight pathogens also act in the brain and modulate behavior.”, – shared one and the author of the study.
