Study sheds light on molecular and cellular mechanisms that cause type 2 diabetes

Since 2004, Claude Knauf (INSERM) and Patrice Cani (UCLouvain) have been collaborating on molecular and cellular mechanisms in order to understand the causes of the development of type 2 diabetes and above all to identify new therapeutic targets.

Study: Antibiotics have prolonged effects on breast milk microbiota in mothers of preterm infants

A team led by researchers at the University of Toronto and The Hospital for Sick Children has found that mothers of preterm babies have highly individual breast milk microbiomes, and that even short courses of antibiotics have prolonged effects on the diversity and abundance of microbes in their milk.

Irritable bowel disease heightens the risk of dementia

Scientists have long explored the link between the gut and the brain. Now, a new study shows that older adults with chronic inflammation of the digestive tract may develop dementia more than seven years earlier than those who do not have the condition.

Mother's prenatal psychological distress is linked to infant gut microbes

Mother's chronic prenatal psychological distress and elevated hair cortisol concentrations are associated with gut microbiota composition of the infant, according to a new publication from the FinnBrain research project of the University of Turku, Finland.

Changes in gut mucus are linked to brain disorders

Mucus is the first line of defense against bad bacteria in our gut. But could it also be part of our defense against diseases of the brain?

Gut microbiome influences pattern of activation in rat’s brain during opioid addiction

When Sierra Simpson was in college, she was sick for a year with recurring fevers and vomiting. Her doctors couldn't figure out what she had. Suspecting a bacterial infection, they tried treating her with high doses of antibiotics.

A specialized gut-brain circuit mediates sugar preference

A little extra sugar can make us crave just about anything, from cookies to condiments to coffee smothered in whipped cream. But its sweetness doesn't fully explain our desire. Instead, new research shows this magic molecule has a back channel to the brain.

Discovery of specialized gut-brain circuit offers insight into sugar preference

Artificial sweeteners have never fully succeeded in impersonating sugar. Now, a Columbia study in mice has identified a brain mechanism that may explain why.

Research shows entire brain responds to the gut through neuronal connections

You know that feeling in your gut? We think of it as an innate intuition that sparks deep in the belly and helps guide our actions, if we let it. It's also a metaphor for what scientists call the "gut-brain axis," a biological reality in which the gut and its microbial inhabitants send signals to the brain, and vice versa.

Unraveling gut-to-brain communication paves way for targeted treatments

Scientists at Flinders University have, for the first time, identified a specific type of sensory nerve ending in the gut and how these may 'talk' to the spinal cord, communicating pain or discomfort to the brain.

Gut bacteria composition and diversity linked to human personality traits

Dr. Katerina Johnson, who conducted her Ph.D. in the University's Department of Experimental Psychology, was researching the science of that 'gut feeling' - the relationship between the bacteria living in the gut (the gut microbiome) and behavioral traits.

Gut microbiome linked to behavioral problems in children

Children with behavioral problems may have different compositions in their gut microbiome, with parents playing a major role in how pronounced the differences were, other than the food they provide, a new study suggests.

TBI impairs growth hormone production, disrupting cognition, memory and sleep

More than 2.5 million people in the United States alone experience a traumatic brain injury, or TBI, each year. Some of these people are plagued by a seemingly unrelated cascade of health issues for years after their head injury, including fatigue, depression, anxiety, memory issues, and sleep disturbances.

Drops containing a specific probiotic strain can reduce colic in infants

Probiotics--or "good bacteria"--have been used to treat infant colic with varying success. In a new trial published in the journal Alimentary Pharmacology & Therapeutics, investigators have shown that drops containing a particular probiotic strain (Bifidobacterium animalis subsp. lactis BB-12) reduced the duration of daily crying by more than 50% in 80% of the 40 infants who received the probiotic once daily for 28 days.

New insights into how immune system and inflammation play a role in PD

Relatively new research findings indicating that the earliest stages of Parkinson's disease (PD) may occur in the gut have been gaining traction in recent years. In a review published in the Journal of Parkinson's Disease, Tomasz Brudek, PhD, evaluates evidence for the association between inflammatory bowel disease (IBD) and PD and proposes directions for future research.

Unhealthy gut microbiome reduces brain synaptic pruning, impairs learning

A new study by Weill Cornell Medicine and Cornell University has come up with more explanations of how gut microbes communicate with the brain neurons. The study, published in the journal Nature on October 23, 2019, examined the brains of mouse models and found that when the gut microbiome is significantly reduced, there are changes in gene expression in the brain’s microglial cells.
