Novel cell-based analysis reveals region-dependent changes in microglial dynamics in grey matter in a cuprizone model of demyelination.

Microglia are key players in Multiple Sclerosis (MS), expressing many susceptibility genes for this disease. They constantly survey the brain microenvironment, but the precise functional relationships between microglia and pathological processes remain unknown. We performed a detailed assessment of microglial dynamics in three distinct grey matter regions in a cuprizone-induced demyelination model.
