Abstract Alveolar macrophages (AMs) and recruited monocyte-derived macrophages (MDMs) mediate early lung immune responses to Mycobacterium tuberculosis. Differences in the response of these distinct cell types are poorly understood and may provide insight into mechanisms of tuberculosis pathogenesis. The objective of this study was to determine whether M. tuberculosis induces unique and essential antimicrobial pathways in human AMs compared with MDMs. Using paired human AMs and 5-d MCSF-derived MDMs from six healthy volunteers, we infected cells with M. tuberculosis H37Rv for 6 h, isolated RNA, and analyzed transcriptomic profiles with RNA sequencing. We found 681 genes that were M. tuberculosis dependent in AMs compared with MDMs and 4538 that were M. tuberculosis dependent in MDMs, but not AMs (false discovery rate [FDR] < 0.05). Using hypergeometric enrichment of DEGs in Broad Hallmark gene sets, we found that type I and II IFN Response were the only gene sets selectively induced in M. tuberculosis–infected AM (FDR < 0.05). In contrast, MYC targets, unfolded protein response and MTORC1 signaling, were selectively enriched in MDMs (FDR < 0.05). IFNA1, IFNA8, IFNE, and IFNL1 were specifically and highly upregulated in AMs compared with MDMs at baseline and/or after M. tuberculosis infection. IFNA8 modulated M. tuberculosis–induced proinflammatory cytokines and, compared with other IFNs, stimulated unique transcriptomes. Several DNA sensors and IFN regulatory factors had higher expression at baseline and/or after M. tuberculosis infection in AMs compared with MDMs. These findings demonstrate that M. tuberculosis infection induced unique transcriptional responses in human AMs compared with MDMs, including upregulation of the IFN response pathway and specific DNA sensors.
