PTAFR
血小板激活因子受體（Platelet-Activating Factor Receptor，PAFR）是一種G蛋白偶聯受體，廣泛分布于血小板、中性粒細胞及血管內皮細胞表面。該受體因介導炎癥級聯反應而聞名，當與配體PAF結合后，可觸發細胞內鈣離子釋放并激活磷脂酶C，進而促進血管通透性增高、白細胞趨化及血小板活化。其異常活化與急性呼吸窘迫綜合征、過敏性休克、動脈粥樣硬化等病理過程密切相關，在膿毒癥中常作為促炎介質加劇全身炎癥反應。
目前全球已開發多款PAFR拮抗劑，如昔帕芬旦（TCV-309）和來帕泛（Lexipafant）曾進入敗血癥臨床試驗，但因療效未達預期而終止。近年研究轉向該受體在腫瘤微環境中的作用，發現其通過調控NF-κB通路促進乳腺癌轉移，相關小分子抑制劑正在臨床前評估中。某些抗組胺藥物被發現具有非特異性PAFR阻斷效應，這為哮喘等過敏性疾病治療提供了新的聯合用藥思路。
