Metabolic Enzyme Alterations and Astrocyte Dysfunction in a Murine Model of Alexander Disease With Severe Reactive Gliosis

Abstract

The article contains the first whole brain proteomic survey from a mouse model of Alexander disease (AxD). Several novel findings include activation of the PPAR signaling pathway, which has been reported to be protective in models of amyotrophic lateral sclerosis (ALS). Another finding related to the gliosis phenotype in AxD mice was the upregulation of fatty acid binding protein 7 (FABP7), which induces an NF-B inflammatory response and counteracts the antiinflammatory effects of PPAR signaling.
