Description
The abstract describes opposing roles of A1 (harmful, complement-mediated) versus A2 (protective, neurotrophic) reactive astrocytes but doesn’t explain the mechanistic switches governing this phenotypic decision. Understanding this binary fate determination is crucial for developing astrocyte-targeted AD therapies.
