摘要 目的研究水通道蛋白亚型(AQPs)在人鼻黏膜组织不同部位的表达分布及其生理意义。方法取18例单纯行鼻中隔矫正术患者的鼻黏膜,经4%多聚甲醛固定,石蜡包埋,连续切片,应用免疫组化技术检测AQP1、2、3、4、5在鼻黏膜组织中分布情况。结果AQP1、2、4为1∶1 000;AQP3为1∶300;AQP5为1∶400的一抗浓度可以观察到它们在鼻黏膜组织不同部位稳定、清晰的染色反应。AQP1在腺上皮细胞膜、腺腔腔面膜、纤毛和血管内皮处被标记;APQ2在基底膜处表达很强;AQP3和AQP4在浆液腺上皮细胞胞浆内表达清晰;AQP5在纤毛、基底膜、腺上皮细胞胞浆处有广泛表达。结论AQP1、2、3、4、5广泛分布于鼻黏膜组织不同部位,其定位分布和反应强弱存在差异,每种AQP的调节可能都是单一的。
