Tiny Gut Imposters Could Be Driving Multiple Sclerosis

New research reveals that when gut bacteria closely resemble the myelin sheath that protects nerve fibers, the immune system can become confused and attack both — accelerating multiple sclerosis. In mouse experiments, bacteria engineered to mimic myelin triggered faster disease progression by activating aggressive immune cells that infiltrated the nervous system.

Strong Marriages May Rewire Brain–Gut Signals

Strong emotional support within marriage may help protect against obesity by altering how the brain and gut communicate. People in highly supportive marriages showed better control of food cravings, healthier gut metabolism, and higher levels of oxytocin, a hormone linked to bonding and appetite regulation.

No Evidence the Gut Microbiome Causes Autism

Experts reviewing decades of research conclude there is no scientific evidence that the gut microbiome causes autism. They highlight major flaws in observational studies, mouse experiments, and clinical trials, including inadequate sample sizes and contradictory findings.

Why Women Face Worse Long COVID

New research reveals that women with long COVID show distinct biological disruptions — including gut inflammation, anemia, and abnormal hormone levels — that may explain their heightened and persistent symptoms. These findings emerged from immune, biomarker, and genetic analyses in people one year after infection.

Gut Microbes May Shape Brain and Behavior Through Hidden Mutations

In a groundbreaking study using Merino sheep, researchers uncovered that tiny genetic variations within gut microbes can influence brain-related behavior. By sequencing over 5,000 microbial genomes—including 3,500 never before reported—they linked single nucleotide variations (SNVs) in microbes to neurobehavioral traits and plasma metabolites tied to brain function.

Reelin Shows Promise for Healing Both Gut and Depression

A new study reveals that the protein Reelin may hold the key to treating both “leaky gut” and major depressive disorder. Chronic stress lowers Reelin levels in the gut, weakening the intestinal barrier and allowing toxins to trigger inflammation that worsens depression.

Sugary Drinks Linked to Depression Through Gut Microbiome

A new study shows that sugary drinks don’t just affect physical health—they may also raise the risk of depression in women by disrupting the gut microbiome. Researchers found that high consumption of soft drinks was linked to both a greater likelihood of major depressive disorder and more severe symptoms, particularly among women.

Gut Microbes May Hold the Hidden Key to Why We Sleep

A new study shows that bacterial cell wall molecules, specifically peptidoglycan, are present in the brain and fluctuate with sleep cycles. This finding supports a hypothesis that sleep is not solely brain-regulated but arises from the interplay between the body and its microbiome.

Oral Bacteria May Trigger Parkinson’s Disease

Scientists have uncovered a direct link between oral bacteria and Parkinson’s disease. They found that Streptococcus mutans, best known for causing cavities, can settle in the gut and release metabolites that reach the brain.

Gut Problems in Autism Linked to Sleep, Behavior, and Sensory Challenges

A long-term study tracking 475 children found that autistic children are far more likely to experience persistent gastrointestinal issues than their peers. These symptoms often co-occur, persist across childhood, and strongly relate to challenges with sleep, communication, behavior, and sensory processing.

Gut Immune Cells Found Migrating to Alzheimer’s Brain

Researchers have uncovered a surprising link between gut immune cells and the brain in Alzheimer’s disease. In mice, antibody-producing B cells that normally reside in the gut were found migrating into brain border regions, influenced by chemokine signals from inflammatory brain cells.

Gut Neurons Direct Immune Healing After Inflammation

Researchers have discovered that neurons in the gut play a direct role in guiding immune healing after inflammation by producing a molecule called adrenomedullin 2 (ADM2). This molecule stimulates group 2 innate lymphoid cells (ILC2s) to release amphiregulin, a tissue-repairing factor, offering protection in models of inflammatory bowel disease.
