Artificial intelligence reveals a treasure trove of antimicrobial molecules

The findings suggest that artificial intelligence can help uncover new antibiotics, opening the way for new approaches to antibiotic discovery. The work also offers an open-access resource for antibiotic developers.

New antibiotic kills harmful bacteria while sparing the gut microbiota

The findings of a recent study may inform the development of antibiotics that kill harmful bacteria and not beneficial ones.

Study identifies gut microbiota differences in polycystic ovary syndrome

The findings of a recent study suggest that the gut microbiota of women with PCOS and dyslipidemia differs from that of women with PCOS only and healthy women.

A specific strain of gut bacteria boosts cancer therapy in mice

The findings of a recent study suggest that the combination of anti-PD-1 immunotherapy with a lack of TREM2 generates a gut environment that promotes inflammation, which improves tumor rejection.

How gut bacteria may impact a woman’s health

The findings of a recent study suggest that gut bacteria transform steroids into hormones that may impact a woman’s health, especially during pregnancy.

Small study reveals metformin-induced changes in the gut microbiota of diabetes patients

The findings of a recent study suggest that metformin regulates glucose metabolism by altering specific gut bacteria rather than by causing a general increase in microbial diversity.

A father’s gut microbes affect the next generation’s health and lifespan

The work, published in Nature, found a link between the gut, its microbiota and reproductive cells in mice.

A high-fat diet promotes breast cancer by altering gut microbial metabolism

The findings of a recent study suggest that Desulfovibrio can drive cancer progression, paving the way for therapeutic approached that targeting the gut microbiota.

How do worms and gut microbes interact during early life?

The authors advocate for further research on worm-microbiota interactions, suggesting that new animal models could help inform strategies for improving health during early life.

Post-surgery infections are often caused by skin bacteria

The findings of a recent study may help clinicians to select more targeted antimicrobials based on where on the body the surgery is taking place or which type of bacteria…

Vitamin D boosts cancer immunity by altering gut bacteria

The findings uncover a link between vitamin D, the immune system and gut bacteria, and they suggest that vitamin D levels could be important for cancer immunity and the efficacy…

AI-powered approach helps researchers to model the infant microbiota

The findings of a recent study show that Q-net can accurately predict the long-term trajectories of gut microbes and identify patterns indicative of future cognitive deficits.

Infant gut microbiota has its own circadian rhythm

The findings of a recent study suggest that the infant gut microbiota begins to develop circadian rhythms soon after birth, with diet having minimal influence on these microbial patterns.

Gut microbes may contribute to autoimmune kidney disease

The findings of a recent study reveal how gut bacteria modify immune molecules in ways that lead to the development of IgA nephropathy.

Industrial societies may be losing gut microbes that help digest plants

The findings of a recent study suggest that Ruminococcus bacteria were more prevalent in ancient human populations and non-industrialized societies, likely due to the high dietary fiber intake.

Gut microbiota may shape a newborn’s immune system through serotonin production

The findings of a recent study suggest that the infant microbiota produces neurotransmitters that are required for the development of the immune system.

The interplay of diet and the microbiota may influence gut inflammation

The results of a recent study suggest that certain dietary changes can counteract bacterial functions that promote disease. The findings thus underscore the importance of examining microbial functions to understand…

Microbial signature linked to improved response to immunotherapy in older people

The findings of a recent study highlight the importance of considering age-related immune changes and gut microbiota composition for developing personalized immunotherapy approaches.

Microbial metabolites promote colon cancer by suppressing anti-tumor responses

A recent study demonstrated causation between microbial DCA metabolism and anti-tumor CD8+ T cell response in colorectal cancer.

Cholesterol-metabolizing gut microbes may protect against heart disease

The findings of a recent study shed light on how the microbiota impacts cholesterol levels. They may also inform microbial-based interventions against high cholesterol.
