Leaky intestines and an abnormal mix of gut microbes may contribute to autism symptoms, a study of mice suggests.
A skewed mixture of intestinal microbes results in high levels of certain chemicals, including one similar to a compound found in the urine of some children with autism, researchers report in the Dec. 19 Cell. Mice with autism-like behaviors also have leaky intestines, which allow the chemicals to build up in the animals’ blood, the team found.
