Human alveolar macrophage response to Mycobacterium tuberculosis: immune characteristics underlying large inter-individual variability

Abstract Mycobacterium tuberculosis (M.tb) infection infects human alveolar macrophages (HAMs). In freshly isolated HAMs from 28 healthy adults, we observe large inter-individual differences in bacterial uptake and growth, with tenfold variation in M.tb load by 72 h. While M.tb infection triggers ex...
