Spinal Cord Microglia In Chronic Neurodegenerative Pain is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Spinal Cord Microglia are key mediators of chronic pain in neurodegenerative conditions. Following nerve injury or central sensitization, microglia adopt a reactive phenotype that drives pain hypersensitivity through pro-inflammatory cytokine release and altered synaptic processing.
- Nerve injury: Peripheral nerve damage
- Central sensitization: Dorsal horn changes
- Neuroinflammation: Cytokine signaling
- ATP release: P2X4 receptor activation
- Process retraction: From ramified to ameboid
- Proliferation: Increased numbers
- Clustering: Around injury site
- Upregulated markers: Iba1, CD11b
- IL-1β: Sensitizes dorsal horn neurons
- TNF-α: Increases excitability
- IL-6: Contributes to wind-up
- BDNF release: Alters chloride reversal
- ATP activation: From damaged neurons
- BDNF release: Via P2X4
- KCC2 downregulation: Chloride dysregulation
- Excitotoxicity: Disinhibition
- Comorbid chronic pain: Common
- Microglial involvement: Similar mechanisms
- Treatment challenges: Analgesic sensitivity
- Pain syndrome: Non-motor symptom
- Central sensitization: Contribute
- Dopaminergic modulation: Pain pathways
- Chronic pain: Frequent complaint
- Microglial activation: Motor cord
- Sensitization: Widespread
- Minocycline: Inhibits activation
- P2X4 antagonists: Block BDNF release
- Cytokine inhibitors: IL-1, TNF blockade
- CSF1R inhibitors: Reduce numbers
- Opioids: Caution in neurodegeneration
- Gabapentinoids: Target sensitization
- Cannabinoids: Modulate microglia
