Src-family kinases activation in spinal microglia contributes to central sensitization and chronic pain after lumbar disc herniation
Background Lumbar disc herniation is a major cause of radicular pain, but the underlying mechanisms remain largely unknown. Spinal activation of src-family kinases are involved in the development of chronic pain from nerve injury, inflammation, and cancer. In the present study, the role of src-family kinases activation in lumbar disc herniation-induced radicular pain was investigated. Results L...
متن کاملCyclo-oxygenase-2 contributes to central sensitization in rats with peripheral inflammation.
It has been widely accepted that prostaglandins are involved in peripheral mechanisms of hyperalgesia. Several lines of evidence suggest that prostaglandins also contribute to the mechanisms underlying hyperalgesia at the level of the spinal cord. The nociceptive flexor reflex of the hind limb was used to test the hypothesis that products of cyclo-oxygenase contribute to the increased excitabil...
متن کاملFractalkine signaling in microglia contributes to ectopic orofacial pain following trapezius muscle inflammation.
Fractalkine (FKN) signaling is involved in mechanical allodynia in the facial skin following trapezius muscle inflammation. Complete Freund's adjuvant (CFA) injection into the trapezius muscle produced mechanical allodynia in the ipsilateral facial skin that was not associated with facial skin inflammation and resulted in FKN but not FKN receptor (CX3CR1) expression, and microglial activation w...
متن کاملPAR2-mediated upregulation of BDNF contributes to central sensitization in bone cancer pain
BACKGROUND Bone cancer pain is currently a major clinical challenge for the management of cancer patients, and the cellular and molecular mechanisms underlying the spinal sensitization remain unclear. While several studies demonstrated the critical role of proteinase-activated receptor (PAR2) in the pathogenesis of several types of inflammatory or neuropathic pain, the involvement of spinal PAR...
متن کاملJNK-induced MCP-1 production in spinal cord astrocytes contributes to central sensitization and neuropathic pain.
Our previous study showed that activation of c-jun-N-terminal kinase (JNK) in spinal astrocytes plays an important role in neuropathic pain sensitization. We further investigated how JNK regulates neuropathic pain. In cultured astrocytes, tumor necrosis factor alpha (TNF-alpha) transiently activated JNK via TNF receptor-1. Cytokine array indicated that the chemokine CCL2/MCP-1 (monocyte chemoat...
