Gut bacterium may weaken treatment responses in esophageal cancer

Lactobacillus salivarius can make cancer immunotherapy less effective by producing indole-3-lactic acid (ILA), that weakens the body’s anti-tumor immune response.

C-section birth may shape babies’ genes, gut microbiota, and brain development

Early interventions targeting the infant gut microbiota, especially in babies born by C-section, may reduce the probability of neurodevelopmental conditions such as autism.

Breastfeeding may offset health impacts of poorer socioeconomic status in children

Supplementation with key beneficial bacteria, alongside efforts to reduce breastfeeding barriers, may offer scalable strategies to reduce socioeconomic health disparities.

Tumor microbiota differences between men and women offer clues to cancer outcomes

The presence of certain microbes was associated with major shifts in tumor gene activity and the immune environment around the cancer.

Mouse study links cognitive side effects of antipsychotics to gut microbes

Targeting the gut microbiota-ergothioneine pathway may offer a new way to prevent or treat cognitive side effects of antipsychotic drugs.

Gut microbes help deliver brain energy molecule, offering new path to treat depression

Supplementing creatine alongside specific gut bacteria such as Bifidobacterium could offer a treatment for depression by restoring brain energy metabolism.

High-fat diets may impair key gut immune cells, weakening intestinal defenses

Reducing dietary fat or controlling gut inflammation could help preserve immune cells and protect gut immunity, offering a strategy to prevent diet-related gut diseases.

Leaky gut may let some bacteria travel to the brain, mouse study shows

Maintaining a healthy gut barrier and microbiota, through diet or other interventions, could help prevent bacteria from reaching the brain, helping maintain neurological health.

Microbial metabolite shows promise against deadly infant disease

Boosting the gut metabolite indoleacrylic acid (IA), either directly or through the probiotic Bifidobacterium longum subsp. infantis, help protect the gut and prevent NEC.

Probiotics may help prevent bacterial vaginosis, small clinical study finds

Using probiotics such as LACTIN-V after antibiotic treatment could help prevent bacterial vaginosis, opening the way for tailored treatments based on individual microbiota profiles.
