Astrocyte-Specific dsRNA–ADAR1 Signalling Links Innate Immunity to Complement Activation in Parkinson’s Disease
Astrocytes is identified as a central site of relative dsRNA accumulation and ADAR1 p150 induction in the PD cortex, and the selective coupling of dsRNA sensing to complement activation in astrocytes highlights a cell-type-specific innate immune pathway that is constitutively present rather than induced by disease.
