Microglia are This response is necessary to clear damaged brain the innate immune cells of the brain that execute this critical function. In healthy brain, microglia perform a housekeeping function, pruning unused syn- apses between neurons. However, microglia become activated to an inflammatory phenotype upon brain injury. Interferon regulatory factors modulate microglial activation and their production of inflammatory cytokines.
