NewsCorrecting imbalance with the gut microbiota after stroke could reduce brain inflammation
An imbalance in ligands, which are molecules produced by the body and the gut microbiota, can affect a key receptor protein that plays a role in brain inflammation after stroke, according to researchers.

NewsThe gut microbiota-metabolites-brain axis mediates social behavior dysfunction following anaesthesia
New research shows that the anaesthetic Sevoflurane (Sev) influences social functioning via the gut-brain axis, with microbiota-derived bile acids serving as critical mediators in this pathway.
-
NewsBacteria invade brain after implanting medical devices
Researchers have discovered that bacteria can invade the brain after a medical device is implanted, contributing to inflammation and reducing the device’s long-term effectiveness.

FeaturesUnder the microscope: the gut-brain axis
Research indicates that the trillions of microbes living in our gut significantly influence our cognitive abilities, emotional well-being, and decision-making processes. This fascinating connection, often called the gut-brain axis, has transformed our understanding of mental health and cognitive function.

NewsResearchers uncover blood metabolites that may influence early childhood development
Researchers have identified small molecules in the blood that may impact early childhood development, showing how dietary exposures, early life experiences, and gut health can influence a child’s growth and cognitive milestones.

NewsStudy reveals direct gut-brain communication via vagus nerve
A new study in an animal model provides direct evidence for the role of the vagus nerve in gut microbiome-brain communication, addressing a critical gap in the field.

NewsBacteria, brains, and sugar: scientists uncover new connections
Using a new method to study how carbohydrates modify proteins, scientists have discovered that gut bacteria can alter molecular signatures in the brain.
-
NewsScientists reveal gut microbes’ hidden role in anxiety—Could probiotics be the next mental health breakthrough?
Scientists have discovered a crucial connection between gut microbes and anxiety-related behaviour, suggesting that microbial metabolites – specifically indoles – play a direct role in regulating brain activity linked to anxiety.

NewsNIH awards $20.6 million grant to establish Human Virome Characterization Center at UCLA
NIH has awarded a $20.6 million grant over five years to establish one of five Human Virome Characterization Centers to advance understanding of the virome’s role in human health and disease across the oral-gut-brain axis.

NewsThe gut-brain connection in Alzheimer’s unveiled with X-rays
Scientists have discovered how X-ray micro- and nano- tomography can provide clues on the processes that link the gut neurons with those in the brain and may trigger Alzheimer’s.
-
NewsBiotin may shield brain from manganese-induced damage, study finds
New research showing the mechanisms by which manganese inflicts damage to the central nervous system suggests that the vitamin biotin - synthesized by gut bacteria - may have a protective effect, potentially mitigating manganese-induced damage.
-
NewsMediterranean diet changes gut bacteria, boosting memory and cognition
A new study suggests the Mediterranean diet’s brain-boosting benefits may work by changing the balance of bacteria in the gut.
-
NewsHealing the gut can reduce long-term impact of stroke, new research finds
A new study found that a drug that was effective at protecting the brain in the immediate aftermath of a stroke failed to prevent long-term cognitive impairment when applied only to the brain. The same drug, when applied to the gut, reduced impairment significantly.
-
NewsGut microbes play a key role in regulating stress responsiveness throughout the day
A pioneering study has uncovered the vital role that gut microbiota plays in regulating stress responses by interacting with the body’s circadian rhythms.
-
NewsResearchers receive 9.5 million grant to study relationship between polyphenol intake, Alzheimer’s and the brain-gut-microbiome system
UCLA Health researchers, in collaboration with researchers from the Republic of Ireland and Northern Ireland, have received a $9.5 million award to study the effects of polyphenols on cognitive health and the brain-gut microbiome system.
-
NewsChemotherapy disrupts gut microbiome in patients with breast cancer
Patients treated with chemotherapy who showed decreases in cognitive performance also had reductions in the diversity of their gut microbiome, a new study has found.
-
NewsNew approach to measuring ‘healthy microbiomes’ in nature and the gut
Focusing on four common diseases – diabetes, heart disease, depression and bowel cancer – new research provides insights into the importance of a healthy microbiome balance in the human gut and in the environment.
-
NewsResilience shaped by activity in the gut microbiome and brain
Resilient people exhibit neural activity in the brain regions associated with improved cognition and regulating of emotions, and are more mindful and better at describing their feelings - but also exhibit gut microbiome activity linked to a healthy gut.
-
NewsTreating the gut-brain connection with B vitamins could help treat Parkinson’s Disease, study finds
Researchers found a reduction in the gut bacteria of genes responsible for synthesizing essential B vitamins and identified a relationship between the lack of these genes and low levels of agents that help maintain the integrity of the intestinal barrier.

NewsStudy shows a high-fat diet may fuel anxiety by disrupting gut bacteria
A new study found that in animals, a high-fat diet disrupts resident gut bacteria, alters behavior and, through a complex pathway connecting the gut to the brain, influences brain chemicals in ways that fuel anxiety.
