Neurons regulate glycolysis dynamically in response to metabolic stress. GIGP-40.mp4

Traditionally, neurons were thought to rely primarily on blood-glucose-derived glucose, with astrocytes managing glycogen storage. However, evidence now indicates that neurons can engage in their own glycogen-dependent glycolytic plasticity (GDGP) to meet sudden metabolic demands. This paper investigates how GDGP operates, specifically in mitigating the effects of mitochondrial dysfunction. Findings on GDGP Mechanisms

GDGP becomes critical during conditions of transient hypoxia or mitochondrial dysfunction, acting as a backup fuel source to sustain synaptic vesicle recycling. To make this paper more accurate for your

The enzyme PYGL-1 is necessary for this metabolic flexibility.

Glycogen serves as a direct fuel source to sustain glycolytic plasticity and synaptic function in vivo. The inability to utilize GDGP is associated with deficiencies in synaptic vesicle recycling during hypoxia. However, evidence now indicates that neurons can engage

Neurons employ both glycogen-dependent (GDGP) and glycogen-independent pathways to maintain glycolytic plasticity. Conclusion
