β-Amyloid activates reactive astrocytes by enhancing glycolysis of astrocytes.

The results revealed that Aβ could indirectly activate A1 astrocytes by Aβ-activated microglia, which depended on the up-regulation of the glycolysis of astrocytes. The glycolysis was crucial for the activation of the neurotoxic A1 astrocytes and inhibiting the glycolysis of neurotoxic A1 astrocytes might be a new therapeutic strategy for AD.
