IRF7 is linked to regulation of cholesterol- and inflammation-modulating genes in macrophages. In murine bone marrow derived macrophages, incubation with DAMP-enriched cholesterol-enriched medium resulted in increased expression of Abca1, Abcg1, Nr1h2 (LXRβ) and Nr1h3 (LXRα), and decreased expression of Cd36; regulation of these factors was reversed by knockdown of Irf7. Furthermore, with respect to inflammation, siRNA-knockdown of Irf7 upregulated Arg1 and Il10, and significantly downregulated Tnfa, Nos2, Il6, and Ccl2 in bone marrow derived macrophages [92]. In those studies, it was shown that RAGE ligands upregulate Irf7 in macrophages.
