Comparing 2 hypotheses side-by-side
**Molecular Mechanism and Rationale** The hexokinase 2 (HK2)-mediated metabolic switch represents a fundamental regulatory mechanism governing astrocyte phenotypic polarization between the neurotoxic A1 and neuroprotective A2 states. HK2, the predominant hexokinase isoform in the brain, catalyzes the ATP-dependent phosphorylation of glucose to glucose-6-phosphate, the rate-limiting step of glycolysis. This enzyme's unique mitochondrial localization through its interaction with the voltage-depen
## **Molecular Mechanism and Rationale** The therapeutic strategy of metabolic reprogramming through microglial glycolysis inhibition represents a novel approach to neurodegeneration that exploits the fundamental metabolic differences between inflammatory M1 and anti-inflammatory M2 microglial phenotypes. At the molecular level, this intervention targets hexokinase 2 (HK2), the rate-limiting enzyme in glycolysis that catalyzes the phosphorylation of glucose to glucose-6-phosphate. HK2 is partic
