Astrocytes ACLYmate to chronic neuroinflammation

Abstract

Astrocytes are essential cells of the mammalian central nervous system (CNS), with key roles in development, homeostasis, and disease. Lee and colleagues recently showed that astrocytes can develop epigenetic memory, which enhances proinflammatory responses to subsequent stimulation, potentially driving sustained neurological disease pathology, such as in multiple sclerosis (MS).
