Silencing neuroinflammatory reactive astrocyte activating factors ameliorates disease outcomes in perinatal white matter injury

Abstract

AbstractThe role of reactive astrocytes in perinatal white matter injury (WMI) is unclear. In a mouse model of WMI, we provide evidence that impairing the formation of aC3-expressing neuroinflammatory reactive astrocyte sub-state rescues myelination and behavioral deficits. We further demonstrate the presence ofC3-expressing reactive astrocytes in human WMI. Our data point to these cells as putative drivers of myelination failure in WMI and a potentially promising therapeutic target.
