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

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

University of Toronto researchers have expanded our understanding of bacterial immunity with the discovery of a new protein that can both sense and counteract viral infections. In the study, published ...

Biologists from ETH Zurich have discovered speargun- like molecular injection systems in two types of bacteria and have described their structure for the first time. The special nanomachines are used ...

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

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