Host-pathogen interactions in tuberculosis should be studied at the disease site because Mycobacterium tuberculosis is predominately contained in local tissue lesions. Although M. tuberculosis infection involves different clinical forms of tuberculosis, such as pulmonary tuberculosis, pleural tuberculosis, and lymph node tuberculosis, most studies of human tuberculosis are performed using cells from the peripheral blood, which may not provide a proper reflection of the M. tuberculosis-specific immune responses induced at the local site of infection. A very low proportion of M. tuberculosis-specific effector T cells are found in the blood compared with the infected tissue, and thus there may be considerable differences in the cellular immune response and regulatory mechanisms induced in these diverse compartments. In this review, we discuss differences in the immune response at the local site of infection compared with the peripheral circulation. The cell types and immune reactions involved in granuloma formation and maintenance as well as the in situ technologies used to assess local tuberculosis pathogenesis are also described. We need to strengthen and improve the exploratory strategies used to dissect immunopathogenesis in human tuberculosis with the aim to accelerate the implementation of relevant research findings in clinical practice.
