Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs.

Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. A consortium led ...

New research into antimicrobial peptides, small chains of amino acids able to damage bacterial cells, shows why some peptides are more effective at doing that and also why some cells are more ...

Bacterial sensory systems represent a dynamic and rapidly evolving area at the intersection of molecular microbiology and biochemistry, where recent ...

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of cells. By systematically ...

A bacterial defense system called SPARDA employs kamikaze-like tactics to protect cells and could be useful in future ...

New research shows that the gene PTPN2 helps regulate gut bacteria and plays a key role in protecting the body from excessive inflammation. Scientists at the, Riverside, are uncovering how a single ge ...

University of Otago scientists are harnessing the power of peptides – the body's own tiny protein molecules – for a spray to help the red meat industry solve headaches around bacterial contamination ...

A new study reveals that age-related changes in the gut microbiota directly impair intestinal stem cell (ISC) function and that restoring a youthful microbial environment can reverse this decline.
