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. Here, MMP1 is linked to tuberculosis.
