Abstract:
P2X receptors (P2XRs), membrane ion channels activated by extracellular adenosine 5' -triphosphate (ATP), play a pivotal role in nociception by directly promoting pain signaling. Currently, antagonists targeting P2XRs have taken effect in alleviating various pain. The therapeutic potential of the P2X receptor family has become a central focus. Consequently, numerous research groups and pharmaceutical companies are actively engaged in developing novel P2XR antagonists. Furthermore, an increasing number of clinical trials on P2XR antagonists have obtained encouraging results. This review provides an overview of the structural characteristics and cellular localization of P2XRs, their molecular mechanisms and signaling pathways implicated in orofacial pain. Additionally, it explores the development of P2XR antagonists and their therapeutic application for managing orofacial pain. In conclusion, this review highlights the promising role of P2XRs as therapeutic targets for orofacial pain treatment.
