Long-term Glatiramer Acetate Treatment Induces Subtle Changes in Microglial Transcriptome
In this study, we investigated the therapeutic potential of a well-tolerated immunomodulatory relapsing-remitting multiple sclerosis drug, glatiramer acetate (GA), on the 3xTg mouse model of Alzheimer's Disease. Briefly, we treated aged female 3xTg mice (>15 mo) weekly with 0.1 mg of GA for 8 weeks. We were able to observe an improvement in cognition and amelioration of amyloid pathology, which we attempted to correlate with changes in microglial transcriptome. To this end, we sorted microglia (CD45int CD11b+) from the hippocampi of GA or PBS-treated 3xTg mice for bulk RNA-seq. Overall design: Microglia (CD45int CD11b+) were sorted from isolated hippocampi and processed for bulk RNAseq.
