Purinergic signaling in microglia in the pathogenesis of neuropathic pain
Nerve injury often causes debilitating chronic pain, referred to as neuropathic pain, which is refractory to currently available analgesics including morphine. Many reports indicate that activated spinal microglia evoke neuropathic pain. The P2X4 receptor (P2X4R), a subtype of ionotropic ATP receptors, is upregulated in spinal microglia after nerve injury by several factors, including CC chemok...
متن کاملTranscription factor IRF5 drives P2X4R+-reactive microglia gating neuropathic pain
In response to neuronal injury or disease, microglia adopt distinct reactive phenotypes via the expression of different sets of genes. Spinal microglia expressing the purinergic P2X4 receptor (P2X4R) after peripheral nerve injury (PNI) are implicated in neuropathic pain. Here we show that interferon regulatory factor-5 (IRF5), which is induced in spinal microglia after PNI, is responsible for d...
متن کاملMicroglia in the spinal cord and neuropathic pain
In contrast to physiological pain, pathological pain is not dependent on the presence of tissue-damaging stimuli. One type of pathological pain - neuropathic pain - is often a consequence of nerve injury or of diseases such as diabetes. Neuropathic pain can be agonizing, can persist over long periods and is often resistant to known painkillers. A growing body of evidence shows that many patholo...
متن کاملACUPUNCTURE AND NEUROPATHIC PAIN About neuropathic pain
Neuropathic pain results from damage to, or dysfunction of, the system that normally signals pain. The International Association for the Study of Pain (IASP 2007) defines neuropathic pain as follows: ‘Pain initiated or caused by a primary lesion or dysfunction in the nervous system. Peripheral neuropathic pain occurs when the lesion or dysfunction affects the peripheral nervous system. Central ...
متن کاملCCL2 is a key mediator of microglia activation in neuropathic pain states.
While neuroimmune interactions are increasingly recognized as important in nociceptive processing, the nature and functional significance of these interactions is not well defined. There are multiple reports that the activation of spinal microglia is a critical event in the generation of neuropathic pain behaviors but the mediators of this activation remain disputed. Here we show that the chemo...
