P2RX3
P2RX3，即嘌呤能受體P2X配體門控離子通道3型蛋白，常被稱為P2X3受體，別名P2X3。P2RX3屬于ATP門控的非選擇性陽離子通道家族，主要分布于感覺神經(jīng)元末梢，通過與胞外ATP結(jié)合觸發(fā)鈉、鈣離子內(nèi)流，參與痛覺信號傳導及內(nèi)臟器官的神經(jīng)反射調(diào)控。研究發(fā)現(xiàn)，其過度激活與慢性咳嗽、膀胱過度活動癥及糖尿病神經(jīng)病變密切相關(guān)，在神經(jīng)源性炎癥和內(nèi)臟超敏反應中起關(guān)鍵作用。近年來針對P2X3受體的藥物開發(fā)取得突破，如首個高選擇性拮抗劑Gefapixant（AF-219）已完成Ⅲ期臨床試驗，證實能顯著改善難治性慢性咳嗽患者癥狀，但存在味覺障礙副作用。另有Eliapixant（BAY-1817080）等二代藥物通過結(jié)構(gòu)優(yōu)化降低不良反應，目前處于Ⅱ期研究階段。該靶點同時被探索用于治療間質(zhì)性膀胱炎和神經(jīng)病理性疼痛，其雙重拮抗劑（同時阻斷P2X2/3異源三聚體）在腸易激綜合征等疾病中展現(xiàn)出潛在治療價值。
