Neuropathic pain has been redefined by NeuPSIG as “pain arising as a direct consequence of a lesion or disease affecting the somatosensory syste”. However, pharmacological management for neuropathic pain is not effective, which is correlated with the uncertainty of pathogenesis. For a long time, neuron had been considered acting a major role in the development of neuropathic pain. In recent years, a majority of studies revealed that glia cell also involved in the occurrence and development of neuropathic pain, and neuron-glia interaction is one of the key mechanism of neuropathic pain, including complex signaling pathways as purinergic signaling. This review focuses on recent advances on the role of purinergic receptors in neuropathic pain.
