The results from TB lung transcriptional profiling (Supplementary Data 2), combined with previous studies30, suggested that multiple members of MMPs, including MMP1, MMP2, MMP3, MMP7, MMP8, MMP9, MMP10, MMP11, MMP12, MMP13, and MMP14, were potentially involved in TB-induced lung remodeling. This evidence concerns the gene MMP9 and tuberculosis.
