Dissociation of microglial activation and neuropathic pain behaviors following peripheral nerve injury in the rat.


Peripheral nerve injury commonly leads to neuropathic pain states fostered, in part, by neuroimmunologic events. We used two models of neuropathic pain (L5 spinal nerve cryoneurolysis (SPCN) and chronic constriction injury (CCI)) to assess the role of spinal glial activation responses in producing pain behaviors. Scoring of glial responses subjectively… (More)
