To delineate the molecular and cellular mechanisms by which neuroinflammation and glial cell activation maintain long-term pain states and spread pain signals across the central nervous system.
Reviewed neurobiological literature addressing low-grade spinal and cortical inflammation, blood-brain barrier permeability, and glial-neuronal cross-talk following tissue and nerve injury.
Peripheral injury induces blood-brain barrier permeability changes and microglial activation, triggering sustained low-grade neuroinflammation along ascending pain pathways.
Astrocytes respond to microglial cytokines and aberrant neurotransmitter release with impaired glutamate clearance and actin remodeling, establishing aberrant synaptic networks that broadcast and preserve pain after tissue healing.
Targeting astrocytic network signaling and restoring glial homeostatic function provide an alternative therapeutic paradigm to overcome the limitations of neuronal-focused analgesics.
