Tuberculosis bacteria build 'edible' havens in immune cells

Findings suggest new treatment approaches for leading global cause of death

Bacteria that cause tuberculosis trick immune cells meant to destroy them into hiding and feeding them instead, report scientists. The study results revolve around the ancient battle between the human immune system and bacterial invaders, where immune cells strive to recognize bacteria as the microbes work to evade them. Mycobacterium tuberculosis remains the leading bacterial cause of death globally because, like other successful pathogens (e.g. HIV), it goes beyond evasion to take over functions of immune cells. Although the study was done in mice, the same mechanisms were found in human macrophages infected with TB.
