Friend or foe? Targeting microglia in Alzheimer's disease.

Inflammation is believed to be a component of a number of degenerative brain diseases including Alzheimer's disease. A recent article by Fu and colleagues (2016) demonstrated that the cytokine IL-33 can modulate microglia in an animal model of AD to become better scavengers of beta-amyloid and less pro-inflammatory. The findings have potential therapeutic implications for a number of brain conditions.
