Expression of Tuberculosis in the Lung

Detailed Description
BACKGROUND:
M. tuberculosis infects a third of the world's population, and TB is the leading cause of morbidity and mortality due to a single infectious agent. However, only 5% to 10% of M. tuberculosis-infected subjects without an underlying immunodeficiency develop disease during their lifetimes. Therefore protective immunity is induced in the majority of subjects. Understanding correlates of protection against M. tuberculosis in humans is needed to better direct efforts in the development of antituberculosis vaccines.
DESIGN NARRATIVE:
Patients are treated according to good clinical practice; however, no study medications are given as part of the research study. This study involves a one-time bronchoalveolar lavage and venipuncture to obtain immune cells for laboratory studies of immune responses.
