Gut Bacteria May Offer a Treatment for Autism

A common probiotic holds the key https://medium.com/@the_economist/gut-bacteria-may-offer-a-treatment-for-autism-33e7cb905947 Autism affects people’s social behaviour and communication, and may impair their ability to learn things. All this is well known. Less familiar to most, though, are the gastrointestinal problems associated with the condition. The intestines of children with autism often harbour bacteria different from those in the guts of…

Organophosphorus pesticide chlorpyrifos intake promotes obesity and insulin resistance through impacting gut and gut microbiota

A major protective mechanism is to use the multi-layered mucus structures to keep a safe distance between gut epithelial cells and microbiota. To investigate whether pesticides…

What Our Guts are Telling Us — The Human Microbiome, Evolution and Biodiversity Loss

https://medium.com/@nmahmud_94718/what-our-guts-are-telling-us-the-human-microbiome-evolution-and-biodiversity-loss-92023804bfe The gut microbiome consists of all the bacteria living in an individual’s intestinal tract. Without these bacteria, we would not be able to digest and process the food we eat. They live in an extreme environment and are known to have coevolved with hominids. In one study, 33 mammalian gut microbiomes were compared to…

Gut microbiota modulate neurobehavior through changes in brain insulin sensitivity and metabolism

Obesity and diabetes in humans are associated with increased rates of anxiety and depression. To understand the role of the gut microbiome and brain insulin resistance in these disorders, we evaluated behaviors and insulin action in brain of mice with diet-induced obesity (DIO) with and without antibiotic treatment. We find that DIO mice have behaviors…
