The authors show that astrocytes produce high levels of the adenosine receptor A2A in Alzheimer brains. Reducing the levels of astrocytic A2A boosted memory in young and aging mice and mouse models of Alzheimer disease, whereas activating a related molecular pathway impaired memory. Thus, astrocytes regulate memory and abnormal receptor activity in these cells may contribute to memory disorders.
