Biomarkers of Protective Immunity and Surrogate Markers of TB Disease in Africa

Tuberculosis (TB) is a major health problem, especially in developing countries. Dr. Kaufmann is leading an international consortium that is studying differences in immune system responses between people exposed to TB who never become sick and those who develop the disease, focusing particular attention on people infected with both HIV and TB in endemic African countries. The project's participating laboratories in Europe and the United States are attempting to learn which host responses provide protective immunity against TB and to identify correlates of protective immunity and host biomarkers of TB disease that could help guide the design and testing of improved TB vaccines, drugs, and diagnostics.
