High levels of gut bacterial toxin trigger lupus nephritis

The body's immune reaction to increased levels of a toxic molecule, part of a bacterial species in the human gut, may reveal who is most at risk of developing lupus nephritis, according to a new study led by NYU Langone Health. ...

How an overactive immune system can drive cancer
