‘Second brain’ neurons keep colon moving: Brain in the gut coordinates activity of millions of neurons to propel waste through digestive system

Millions of neurons in the gastrointestinal tract coordinate their activity to generate the muscle contractions that propel waste through the last leg of the digestive system, according to a study of isolated mouse colons published in JNeurosci. The newly identified neuronal firing pattern may represent an early feature preserved through the evolution of nervous systems.

Gut bacteria play key role in anti-seizure effects of ketogenic diet

UCLA scientists have identified specific gut bacteria that play an essential role in the anti-seizure effects of the high-fat, low-carbohydrate ketogenic diet. The study, published today in the journal Cell, is the first to establish a causal link between seizure susceptibility and the gut microbiota — the 100 trillion or so bacteria and other microbes

Big data from world’s largest citizen science microbiome project serves food for thought: How factors such as diet, antibiotics and mental health status can influence the microbial and molecular makeup of your gut

Researchers at University of California San Diego School of Medicine and collaborators have published the first major results from the American Gut Project, a crowdsourced, global citizen science effort. The project, described May 15 in mSystems, is the largest published study to date of the human microbiome — the unique microbial communities that inhabit our

Gut check: Metabolites shed by intestinal microbiota keep inflammation at bay: Researchers find inflammatory response in fatty liver disease is reduced by two tryptophan metabolites from gut bacteria

Researchers at Tufts University have elucidated a mechanism by which the “good” bacteria that reside in our gastrointestinal tract can help protect us from inflammation, and how their disruption (dysbiosis) can increase the susceptibility of the liver to more harmful forms of disease. Their study, now available in the journal Cell Reports, identified two key

Fasting boosts stem cells’ regenerative capacity: A drug treatment that mimics fasting can also provide the same benefit, study finds

As people age, their intestinal stem cells begin to lose their ability to regenerate. These stem cells are the source for all new intestinal cells, so this decline can make it more difficult to recover from gastrointestinal infections or other conditions that affect the intestine. This age-related loss of stem cell function can be reversed

Genetic link to IBS identified in women

New research coordinated by Karolinska Institutet in Sweden links certain DNA variants to increased risk of irritable bowel syndrome (IBS) in women. The findings, published in the scientific journal Gastroenterology, might help explain why IBS is more common in women than in men. Irritable bowel syndrome is the most common gastrointestinal disorder. More than 10
