Reactive astrocytes with GABAergic signature represent a distinct therapeutic target for inhibitory/excitatory imbalance. The SEA-AD dataset identifies astrocytes co-expressing GAD1, GABRG2, and ALDH1A1, suggesting increased GABA production. These GABAergic astrocytes correlate with reduced excitatory synaptic markers in neighboring neurons.
