COL12A1 and tuberculosis: To test the association between MMP1+CXCL5+ fibroblast markers and TB, we again examined the LN dataset and found that 5/10 top unique marker genes in the MMP1+CXCL5+ fibroblast subcluster were upregulated in the LN TB data, including MMP1, CA12, TDO2, POSTN, and COL12A1 (Data S9).
