We could identify 27 genes, including camp, casp1, ccl3, cxcl1, irf7, lcn2, nlrp3, nod2, ripk2, and tlr2, that were differentially expressed in pml+/+ versus pml−/− MEFs following infection (Fig. 2; see also Table S1A in the supplemental material). This evidence concerns the gene NLRP3 and infection.
