Research in mice and humans is beginning to establish a link between the composition of microbes in the gut and immune responses to tumor cells, but the mechanisms are not yet clear.

Molecules produced by resident bacteria and their hosts may signal immune cells to attack the body’s own tissues.

In a study of nearly 400 breastfeeding mothers, researchers find links between directly feeding the child and a more diverse microbiota, compared to milk from pumping.

Researchers find that it’s not just high-risk genes, but how children’s bodies respond to their own intestinal microbiota that relates to future diagnoses of type 1 diabetes.

Transposon mutagenesis give scientists a rare look at the most important interactions within microbial communities.

Using wild mice housed in laboratory conditions, researchers find that gut bacteria compositions change little from one generation to the next.

Acute bouts of diarrhea could have lasting effects on the microbiota and host immune system activation, a mouse study suggests.

A new study finds that more than 200 human-targeted, non-antibiotic drugs inhibit the growth of bacterial species that make up part of the human microbiome.

Including microbiome composition in predictions of whether a person is obese can significantly improve their accuracy, according to an analysis.
