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 ...

A new study reveals how bacteria in the gut can help determine whether the amino acid asparagine from the diet will feed tumor growth or activate immune cells against the cancer, according to ...

In recent years, scientists have begun to reveal the myriad ways that gut microbes can impact our health; they have identified relationships between bacteria in the gastrointestinal tract and the ...

The evidence is mixed, but researchers are watching three specific effects.

Scientists at UT Southwestern Medical Center have discovered that gut bacteria help regulate the development of the body's immune system by directing the movement of vitamin A through a previously ...

Bacteria living in healthy human intestines use molecular syringes to inject proteins that directly bind and adjust immune signaling, according to a peer-reviewed study published in Nature ...

Gut bacteria aren’t just passive passengers—they can actively send proteins straight into our cells. Using microscopic injection systems, even harmless microbes can influence immune responses and ...

The microbes inside our bodies not only help break down food but also impact our health. Yet their precise influence is not always understood, especially in the presence of prescription drugs. Now, ...

A compound made when gut bacteria break down dietary fiber may do more than briefly calm inflammation—it could leave a ...

Scientists at the University of East Anglia (U.K.) have uncovered a hidden link between gut health and the immune system—all thanks to a tiny island bird. Researchers studied the Seychelles warbler, a ...
