abstract：:Chemokines (CK) are potent leukocyte activators and chemoattractants and aid in granuloma formation, functions critical for the immune response to Mycobacterium tuberculosis. We hypothesized that infection of alveolar macrophages (AM) with different strains of M. tuberculosis elicits distinct profiles of CK, which cou...
