Study Suggests Key Link That Could
Gut Microbiota and Health
Recent studies show our gut microbiota affects many aspects of health, including mental health, weight, and autoimmune disorders. A new study links gut microbiota to autism, revealing that a mother’s microbiota influences a child’s autism risk more than the child’s own.
Research Findings
“The microbiome can shape the developing brain in multiple ways,” said John Lukens, lead researcher. The study focused on a molecule called interleukin-17a (IL-17a), which affects brain development in the womb and is involved in immune responses.
Mouse Study on Autism
Researchers tested mice with different gut microbiota. When IL-17a was suppressed, pups behaved typically. Without suppression, pups from moms with inflammatory microbiota showed autism-like behaviors. A fecal transplant confirmed the mother’s microbiota caused this effect.
Future Directions
Though early and mostly in mice, the study suggests a mother’s gut health impacts neurodevelopmental disorders. Lukens said, “IL-17a might be a single component in a much bigger picture,” and the next step is finding specific microbiome factors linked to autism in humans.
