Microbiota differences might shape responses to viral infections

New study suggests that modifying the gut microbiota could shape baseline immune states to improve infection resistance and responses to vaccines and immunotherapies.

Dietary fiber helps probiotics settle in the gut

Diet shapes probiotic colonization, offering strategies to improve colonization, modulate the microbiota, and control harmful microbes.

Mathematical model reveals how gut microbes shift in disease

Monitoring shifts in microbial interaction networks could help to detect and track gut-related conditions.

Gut microbiota maturation may be linked to infection risk in preterm babies

Bacteria such as Enterococcus faecium and Limosilactobacillus reuteri are key in activating an immune receptor that boosts the activity of protective immune cells.

Success of microbiota transplants may depend on specific bacterial strains

Targeting specific bacterial strains, rather than overall gut diversity, can help develop effective microbiota therapies.

Single-cell analysis reveals how harmful bacteria may promote gum disease

In periodontitis, helpful gum bacteria become less active while harmful bacteria change their behavior to feed on available nutrients and worsen disease, suggesting new targeted treatment approaches.

Microbial particles may boost the effectiveness of immunotherapy in stomach cancer

Bacterial extracellular vesicles released by L. salivarius activate immune cells, boosting the effectiveness of immunotherapy in stomach cancer.

Hidden gut bacteria may be key to a healthy microbiota

Uncultured gut bacteria, particularly one group called CAG-170, are key contributors to a healthy microbiota. 

Region-specific infant gut bacteria may pave the way for tailored probiotics

Bifidobacterium longum and B. infantis are distinct species with strains adapted to local diets, highlighting the importance of developing geographically tailored infant probiotics.

Gut protein blocks harmful bacteria and protects intestinal health

HMGB1 is a key protein that blocks bacterial adhesion and virulence, protecting intestinal cells and helping to maintain a healthy microbiota.
