Similar to previous reports, the expression levels of IFIT1, IRF1, and MX1 in Znfx1–/– BMDMs were higher than those in WT BMDMs following H37Rv infection, despite the increased intracellular M. tuberculosis burden in Znfx1–/– BMDMs (Supplemental Figure 4A). The gene discussed is IFIT1; the disease is infection.
