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.

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 Fungus Found to Disrupt Brain’s Alcohol Reward Pathway

A new study reveals that an overgrowth of Candida albicans, a common gut fungus, may alter the brain’s dopamine reward circuitry and influence alcohol consumption. Researchers found that as fungal populations increased, they triggered production of inflammatory molecules called PGE2, which crossed into the brain and changed dopamine signaling in the dorsal striatum.

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.

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 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.

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.

Gut Microbiome May Influence Bipolar Medication Response

A new review has examined how bipolar disorder medications interact with the gut microbiome, revealing important links between treatment response and gut microbial composition. Researchers analyzed 12 studies comparing the microbiomes of treated, untreated, and healthy individuals.

Oral-Gut Bacteria Linked to Dementia Risk in Parkinson’s Disease

A new study has found that bacteria from the mouth may migrate to the gut and contribute to cognitive decline in people with Parkinson’s disease. Researchers identified harmful microbes and their toxins in the gut of Parkinson’s patients with dementia, suggesting a possible link between oral hygiene, gut health, and neurodegeneration.

Gut Microbiota Transplants May Cause Long-Term Imbalance

New research warns that fecal microbiota transplants (FMT) can lead to long-lasting mismatches in gut regions, causing metabolic and behavioral shifts. While FMT aims to restore gut health by transplanting stool microbes from healthy donors, most microbes come from the colon and may colonize unintended regions like the small intestine.

Study Links Gut Bacteria to MS Risk and Reveals Key Triggers

A new twin study has identified specific gut bacteria that may contribute to the development of multiple sclerosis (MS), the most common inflammatory disease of the central nervous system. By comparing identical twins where only one has MS, researchers reduced confounding genetic and environmental factors and pinpointed 51 bacterial taxa with different abundances.

Acetate and Bacteria Team Up to Burn Fat

A new study reveals that acetate—when paired with specific gut bacteria—can significantly reduce fat and liver mass in both normal and obese mice. Researchers used a supplement called AceCel, which delivers acetate directly to the large intestine, promoting the growth of Bacteroides bacteria.
