Some viruses that infect bacteria carry an enzyme that gives them away. When that enzyme, a protease, cuts a particular ...

Researchers have uncovered a new way bacteria detect viral attacks: a virus-produced enzyme cuts a bacterial sensor protein, triggering a self-destructing immune response. The discovery could lead to ...

When scientists assess how dangerous a bacterium is, the first question often seems simple: Can it be stopped or killed? In ...

Epithelial cells form the body's frontline barriers, helping keep microbes, toxins and other harmful substances out. Yet ...

New research shows that bacterial proteins injected into gut epithelial cells, rather than those left on the bacterial ...

Immune cells that eat bacteria in the body don't stash them in specialized compartments as once thought, but turn them into critical nutrients that build proteins, create energy and keep the cells ...

Mitochondria have primarily been known as the energy-producing components of cells. But scientists are increasingly discovering that these small organelles do much more than just power cells. They are ...

New research has shown how collaboration can even be beneficial in the microbial world. A study reported in Science has outlined how bacterial cells can work in unison to survive antibiotic exposure.

A byproduct produced by certain gut bacteria may directly accelerate the brain changes associated with Alzheimer’s disease. Elevated blood levels of this molecule, known as imidazole propionate, ...
