Molecular anchors on gut phages could open new therapeutic avenues

Bacteriophages, or phages, are viruses that infect bacteria and are not considered human pathogens. Yet researchers at the Translational Microbiology Laboratory of the Institute of Biochemistry, HUN-REN Biological Research Centre, Szeged, have shown that some gut phages can also physically interact with human cells. Their study identifies phage surface proteins that act as molecular anchors, promoting attachment to human cells, cellular uptake, and prolonged retention in the gastrointestinal tract. The findings, published in the journal Nature Communications, open new perspectives on how phages behave in the body and may create new opportunities for therapeutic development.
