Human alveolar macrophage response to Mycobacterium tuberculosis: immune characteristics underlying large inter-individual variability
23 Jun 2025
Abstract excerpt
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 expression changes of numerous host mRNAs, we examined which genes are most variably expressed (VE genes) between donors, as...
