A mouse study suggests that imbalances in gut bacteria may influence neural connectivity and depressive symptoms in bipolar disorder, with treatments like lithium showing behavioral improvements, highlighting the gut-brain connection's potential role in bipolar depression.
A study has identified 168 common chemicals, including pesticides and industrial compounds, that harm beneficial gut bacteria, potentially impacting human health and increasing antibiotic resistance, prompting calls for safer chemical testing and regulation.
A compound called TMA produced by gut bacteria may help prevent and manage type 2 diabetes by reducing inflammation and improving insulin response, offering a potential new avenue for treatment and prevention, though more research is needed.
New research from the University of Basel shows that gut bacteria resembling myelin can trigger or slow multiple sclerosis progression in mice, highlighting both risks and potential for microbiome-based treatments that train the immune system to tolerate myelin.
Recent research suggests that gut bacteria, through their metabolites like TMAO and SCFAs, play a significant role in heart attack risk by influencing inflammation, cholesterol, and blood clot formation. Maintaining a healthy gut microbiome via high-fiber diets, probiotics, prebiotics, and lifestyle changes could be a promising strategy for cardiovascular prevention, challenging traditional views that focus solely on cholesterol and blood pressure.
A long-term study suggests that a single dose of healthy gut bacteria can reduce the risk of metabolic syndrome and related health issues in obese teens, with the bacteria remaining in the gut years later, paving the way for targeted probiotic treatments.
Research from the University of Gothenburg shows that gut bacteria can produce serotonin, which may lead to new treatments for irritable bowel syndrome (IBS), as certain bacteria like Limosilactobacillus mucosae and Ligilactobacillus ruminis increase serotonin levels and improve gut function, offering hope for addressing IBS symptoms.
Scientists analyzed the preserved intestines of a 1,000-year-old man from Mexico, revealing a diverse and largely intact ancient gut microbiome that offers insights into pre-industrial human diets and health, highlighting the loss of microbial diversity in modern humans.
The well-preserved 1,000-year-old Zimapán mummy from Mexico revealed an ancient human gut microbiome, including bacteria still common today and a previously unobserved species, providing insights into ancient diets, lifestyle, and microbial evolution.
UC Irvine researchers found that consuming inulin, a vegetable-derived fiber, can reprogram gut bacteria to reduce fructose's harmful effects on the liver, potentially reversing fatty liver disease and insulin resistance, offering new avenues for nutrition-based disease prevention.
Researchers have discovered that smoking produces metabolites like hydroquinone that promote mouth bacteria such as Streptococcus to grow in the gut, which can reduce inflammation in ulcerative colitis. This finding suggests potential treatments using probiotics or prebiotics to mimic smoking's protective effects without the associated health risks.
Canadian scientists discovered that a molecule produced by gut bacteria, D-lactate, fuels blood sugar and liver fat, contributing to diabetes and fatty liver disease. They developed a biodegradable polymer to trap D-lactate in the gut, which improved blood sugar control and reduced liver damage in mice, offering a new approach to treating metabolic diseases by targeting microbial fuel sources before they affect the body.
Research suggests that gut bacteria, particularly Streptococcus pneumoniae, communicate and develop antibiotic resistance through a process called competence, which may help predict and prevent preterm birth by understanding bacterial stress responses and resistance mechanisms.
A 2025 study uncovered how chronic alcohol consumption damages the liver by reducing mAChR4 in the gut, impairing immune control over bacteria, which then escape into the liver and cause inflammation and tissue damage, leading to alcohol-associated liver disease. Restoring gut signaling pathways may offer new treatment options, but further clinical trials are needed.
Emerging research suggests that the body's microbiota, including bacteria in the gut and mouth, can influence sleep quality and circadian rhythms, potentially leading to new treatments for sleep disorders using probiotics or dietary interventions. However, more robust studies are needed to confirm these effects and develop effective therapies.
