title: EFIS lecture. Immune response to tuberculosis: How to control the most successful pathogen on earth.
abstract: Tuberculosis (TB) remains a major health threat and general agreement exists that better control measures are needed. These include better diagnostics, drugs and vaccines. In particular, vaccines will be critical for better TB control. Based on knowledge about protective immunity against TB, a vaccine was created, VPM1002, which shows high protective efficacy and safety in experimental animal models. The vaccine has proven safe and immunogenic in human adults and neonates and is currently assessed in clinical trials in the context of HIV exposure. As a next step, a phase III efficacy trial in adults and a phase IIb efficacy trial in neonates are being planned. Biosignatures that differentially diagnose TB disease versus latent infection with high sensitivity and specificity have been designed. Most recently, a prognostic biosignature which predicts progression from latent infection to active TB has been identified. Biosignatures are not only of great value for improved diagnosis and prognosis of TB, they can also provide guidelines for better understanding of molecular mechanisms underlying disease. Accordingly, distinct biomarkers of diagnostic and prognostic value but of unknown biological function are being characterized functionally. In this way, deeper insights have been obtained on the role of type I interferon and of neutrophils in TB in experimental animal models of TB. In conclusion, clinical and basic research further supported by computational biology can complement each other in the pursuit of knowledge-based development of improved intervention measures for TB control.
