Glucose Metabolism Vulnerable Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
This page provides comprehensive information about the cell type. See the content below for detailed information.
Glucose metabolism-vulnerable neurons are neuronal populations that rely heavily on glucose metabolism and are particularly sensitive to metabolic disturbances. These neurons are affected in conditions of hypometabolism, insulin resistance, and diabetes-related cognitive decline.
- GLUT3: High-affinity glucose transporter
- GLUT1: Endothelial and glial glucose transport
- GLUT4: Insulin-responsive glucose transport

- p-AMPK: Energy sensing
- mTOR: Growth/metabolic signaling
- SIRT1: Metabolic regulation
- PGC-1α: Mitochondrial biogenesis
- Cortical neurons
- Insulin signaling impairment
- GLUT4 dysfunction
- Synaptic insulin resistance
- White matter neurons
- Ischemia-sensitive
