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 ...

Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR). The insights, which expand our ...

Drugs that act against bacteria are mainly assessed based on how well they inhibit bacterial growth under laboratory conditions. A critical factor, however, is whether the active substances actually ...

A research team has discovered a previously unknown mechanism by which the immune system fights bacterial infections. The scientists found that a specific protein, the chloride channel PACC1, is ...

Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. A consortium led by researchers at Helmholtz Munich, with participation from Ludwig ...

The idea that a single-celled bacterium can defend itself against viruses in a similar way as the 1.8-trillion-cell human immune system is still “mind-blowing” for molecular biologist Joshua W. Modell ...

A new Rutgers Health study reveals a surprising twist in the antibiotic resistance story: instead of simply killing bacteria, drugs like ciprofloxacin can actually trigger a kind of microbial survival ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial ...
