In the quiet ecosystem of the human gut, a single bacterium has been found to carry unexpected influence over one of medicine's most pressing challenges. Researchers at the University of Nebraska–Lincoln have shown that Bacteroides uniformis, by converting the amino acid tryptophan into compounds called indoles, can meaningfully strengthen the immune system's capacity to fight cancer. The discovery, confirmed in both laboratory mice and human patient data, suggests that the ancient relationship between our bodies and our microbial inhabitants may hold keys to improving modern immunotherapy.
