What is the molecular mechanism by which oligodendroglial MCT1 disruption causes axon damage and neuron loss?

PARTIALLY ADDRESSED

The study shows that MCT1 disruption leads to axon degeneration and neuron death, but the specific molecular pathways linking lactate transport dysfunction to neuronal damage remain unexplained. Understanding this mechanism is critical for developing targeted neuroprotective therapies. Gap type: unexplained_observation Source paper: Oligodendroglia metabolically support axons and contribute to neurodegeneration. (2012, Nature, PMID:22801498)
