A Dartmouth study finds that molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups. The findings ...

Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that ...

Bacterial glycosylation represents a sophisticated mechanism by which pathogens modify both host and bacterial proteins, thereby subverting immune responses and modulating cellular processes. Central ...

Salmonella bacteria (red) cause up to a million deaths a year worldwide and there is a need for effective vaccines. New work from UC Davis shows how salmonella-specific T-cells can be stimulated to ...

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 ...

Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own advantage. Researchers have now uncovered the attack strategies employed by ...

Researchers have discovered that virus-like nanoparticles can promote the multicellular organization and reproduction of host bacteria. These particles, which are evolutionarily related to phages ...

Bacteria incubated with bacteriophages in space accumulated distinct mutations compared to those on Earth, highlighting the effect of microgravity on microbes.

Rivals or allies—how do bacteria and fungi interact in our bodies? Until now, bacteria on our mucous membranes were primarily ...

Complex cells are thought to be the result of a union between two ancient microorganisms, but scientists have long been ...
