Gut bacteria boost immune system, help send vitamin A to T cells

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 unrecognized cellular network. The preclinical findings, published in Cell Host & M
