A light-activated probe reveals TB immune system evasion mechanisms

Tuberculosis (TB) is an infectious disease that kills more than a million people worldwide every year. The pathogen that causes the disease, Mycobacterium tuberculosis, is deadly in part because of its complex outer envelope, which helps it evade immune responses of infected hosts. Researchers have now developed a chemical probe to study a key component of this envelope. Their results provide a step toward finding new ways of inactivating the ba…

Light-activated probe reveals how tuberculosis evades immune defenses
