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.

This shows a person sleeping and a brain.

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.

AI Reveals Bitter Taste Receptors’ Hidden Role in Gut-Brain Health

Researchers used AlphaFold3, the latest AI-based protein modeling system, to predict the structures of all 25 known human bitter taste receptors (T2Rs). Compared with AlphaFold2, AF3 consistently generated more accurate structural predictions when benchmarked against experimentally determined data.

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 Bacteria and Immune Cells May Drive Autism

Researchers have uncovered a critical connection between the gut microbiota, the immune system, and autism spectrum disorder (ASD). In a germ-free genetic mouse model, removal of gut microbes reduced autism-like behaviors and lowered brain inflammation, showing that microbes may play a dominant role in driving symptoms.

When Gut Rhythms Over-Sync With the Brain, Mental Strain Rises

A large-scale study has found that unusually strong coordination between brain activity and the stomach’s slow, rhythmic waves may signal greater mental distress. Using fMRI and electrogastrography on more than 240 people, researchers observed that higher synchronization was associated with elevated anxiety, depression, and stress.

This shows a person holding their stomach in pain, surrounded by COVID molecules, reflecting how COVID has impacted the gut-brain axis health.

Post-COVID Spike in Gut-Brain Disorders

A major international study confirms that disorders of gut-brain interaction have increased significantly since the COVID-19 pandemic. Using consistent diagnostic tools across 2017 and 2023 populations, researchers found notable surges in IBS and functional dyspepsia.

This shows the biological route from the gut to the brain.

Your Gut May Be the Key to Chronic Fatigue, Long COVID

A groundbreaking study using AI has revealed how ME/CFS disrupts critical connections between the immune system, gut microbiome, and metabolism. The new platform, BioMapAI, achieved 90% accuracy in identifying ME/CFS patients based on stool, blood, and symptom data—offering long-overdue validation for millions living with this debilitating illness.

“Neurobiotic Sense” Tells Brain When You’ve Had Enough

Scientists have discovered a “neurobiotic sense” — a newly identified system where the gut sends real-time signals from microbes to the brain to help regulate appetite. Specialized cells called neuropods in the colon detect a bacterial protein, flagellin, and signal the brain via the vagus nerve to suppress eating.
