New research isِ pointing toِ gut-specific white blood cells (called Treg cells), whichِ learn toِ identify andِ then protect theِ good gut bacteria, telling ourِ bodies Don’t mess withِ them.
Since we’veِ hadِ these microbes living withِ usِ forِ the millennia, we’veِ developed a tolerance toِ them, saidِ Josef Neu, a researcher fromِ the University ofِ Florida whoِ wasn’tِ involved inِ the study.
