  • Leprosy Pathogen Evades Critical Vitamin D-Dependent Immune Response
    A team of UCLA scientists has found that the pathogen that causes leprosy has a remarkable ability to avoid the human immune system by inhibiting the antimicrobial responses important to our defenses. In one of the first laboratory studies of its kind, researchers ...More
