<i>Listeria monocytogenes</i> Infection Induces Prosurvival Metabolic Signaling in Macrophages

Abstract excerpt

Host cells use metabolic signaling through the LXRα nuclear receptor to defend against Listeria monocytogenes infection. 25-Hydroxycholesterol is a natural ligand of LXRs that is produced by the enzyme cholesterol 25-hydroxylase (CH25H). We found that expression of Ch25h is upregulated following L. monocytogenes infection in a beta interferon (IFN-β)-dependent fashion. Moreover, increased Ch25h expression...
