目的：观察麻黄-桂枝药对对白介素-22（IL-22）诱导的人永生化角质形成细胞株（Ha Ca T细胞株）分泌CCL20的影响,探讨麻黄-桂枝药对治疗银屑病的可能作用机制,从而为汗法治疗银屑病提供科学的理论依据。方法：用IL-22刺激Ha Ca T细胞,...目的：观察麻黄-桂枝药对对白介素-22（IL-22）诱导的人永生化角质形成细胞株（Ha Ca T细胞株）分泌CCL20的影响,探讨麻黄-桂枝药对治疗银屑病的可能作用机制,从而为汗法治疗银屑病提供科学的理论依据。方法：用IL-22刺激Ha Ca T细胞,并加入不同浓度的麻黄-桂枝药对水煎液共培养适当时间,运用酶联免疫吸附实验（ELISA）法检测Ha Ca T细胞分泌的CCL20;运用实时定量聚合酶链式反应（RT-PCR）法测定Ha Ca T细胞CCL20mRNA的表达。结果：IL-22能明显促进Ha Ca T细胞分泌CCL20并使CCL20mRNA的表达增加。麻黄-桂枝药对能够抑制IL-22诱导的Ha Ca T细胞分泌CCL20及表达CCL20mRNA,并与其药物浓度成依赖性关系。结论：麻黄-桂枝药对可能是通过抑制角质形成细胞分泌CCL20从而治疗银屑病。展开更多
