New insights into the molecular mechanism between gut microbes and immune cells are published in 2015 by scientists at Weill Cornell Medicine and Cornell ’s research campus . Mice with reduced gut microbes were not able to identify that a protein was no longer present as effectively as healthy mice and showed different gene expression in immune cells in their brains , demonstrating a molecular link between gut health and brain health . The association developed normally both in control animals and in animals that had been treated with antibiotics to deplete their gut microbiota. This may lead to new gut - focused therapies treating conditions from autism to Parkinson 's .
