title: Radical host-specific therapies for TB.
abstract: Although proinflammatory cytokines such as TNF are critical for containment of tuberculosis, they can also exacerbate disease when produced at high levels. In this issue of Cell, Roca and Ramakrishnan demonstrate that high TNF production induces reactive oxygen species in infected macrophages, ultimately leading to macrophage necrosis and bacterial dissemination.
