NLRX1 Inhibits Microglial Inflammatory Responses [Immunology]

This study demonstrates that, in contrast to other NLRs that activate immunity, NLRX1 plays a protective role in experimental autoimmune encephalomyelitis (EAE), a mouse model for multiple sclerosis. When compared with wild-type controls, Nlrx1−/− mice have significantly worsened clinical scores and heightened CNS tissue damage during EAE. NLRX1 does not alter the production of encephalitogenic T cells in the peripheral lymphatic tissue, but Nlrx1−/− mice are more susceptible to adoptively transferred myelin-reactive T cells. Analysis of the macrophage and microglial populations indicates that NLRX1 reduces activation during both active and passive EAE models. This work represents the first case of an NLR that attenuates microglia inflammatory activities and protects against a neur…
