Description
The study shows S100B inhibition reduces both neuroinflammation and glycolytic upregulation, suggesting astrocytes coordinate this metabolic shift. However, the specific signaling pathways connecting S100B to glycolytic enzymes like PFK1 remain unexplained, limiting therapeutic targeting.
