MMP9 and infection: We found 204 genes to be differentially expressed during mycobacterial infection at 2 dpi (Supplemental Data S1 at https://doi.org/10.5281/zenodo.5788543), including upregulation of the matrix metalloproteinase genes mmp13a and mmp9 (Fig. S3A), which is consistent with earlier transcriptomic data of Mm-infected zebrafish at the same time point after infection (47).
