Interestingly, at 20 h post-infection, six of the eight (all but PLEK2 and PLS1) also showed reversal of IFN-γ mediated resistance to L. monocytogenes infection, as illustrated in Figure 8 for THP-1 cells with TNFRSF9 and SERPINI1 gene knockdown. This evidence concerns the gene TNFRSF9 and infection.
