摘要 目的探讨胞浆型磷脂酶A2-δ(cytosolic phospholipase A2-δ,cPLA2δ)表达与银屑病皮损的关系。方法免疫组化法检测银屑病患者皮损组织切片和对照组cPLA2δ的表达;提取银屑病患者皮损组织和对照组的RNA,用逆转录聚合酶链式反应(RT-PCR)检测cPLA2δmRNA表达水平。结果免疫组化法发现银屑病皮损患者cPLA2δ表达阳性率为100%,其中表达阳性例数、中度阳性例数及强阳性例数之间比较差异无统计学意义(2=1.025,P>0.05)。对照组cPLA2δ表达阳性率为7.2%。两组之间cPLA2δ表达阳性率比较差异有统计学意义(2=50.49,P<0.01)。银屑病皮损患者cPLA2δmRNA表达也升高,两组比较差异有统计学意义(t=28.567,P<0.01)。结论 cPLA2δ的高表达与银屑病皮损的发生有关,提示cPLA2δ可作为银屑病分子诊断和靶向治疗的靶点。
