中文摘要: 子痫前期(PE)的病因和发病机制至今不明。失控性炎症反应可能是PE发病的重要机制之一。作为失控性炎症反应中的重要触发者-特定的炎性因子IL-27及其受体WSX-1的表达在PE中异常增高,在我们的前期研究中已被证实。本研究拟采用原代绒毛外滋养层细胞EVTs和PE经典大鼠RUPP模型,利用表达谱芯片,多重蛋白检测技术,siRNA和流式细胞等技术,探究PE发病机制中的失控性炎症反应是否与IL-27的异常表达相关,分析IL-27是否通过激活JAK/STAT3,PI3K/Akt和p38MAPK等信号转导途径触发失控性炎症反应参与PE发病,从而明确IL-27是否可能成为PE预防和治疗的潜在分子靶点。

英文摘要: The etiology and pathogenesis of PE is still unclear. Uncontrolled inflammation is important in the pathogenesis of PE. Our previous studies found that IL-27 and its receptor WSX-1 are significant higher in PE, and as we know they are the important trigger in uncontrolled inflammation. We will apply primary extravillous trophoblast(EVTs), RUPP rats which is the classic PE rat model, expression microarray, detection of multiple protein, siRNA and Flow cytometry technology to explore whether uncontrolled inflammatory response associated with the abnormal expression of IL-27 involved in the pathogenesis of PE, and to analysis whether IL-27 though activated JAK/STAT3,PI3K/Akt and p38MAPK etc signal transduction pathways to trigger uncontrolled inflammatory response involved in the pathogenesis of PE, so as to define whether IL-27 might be a potential molecular target for the prevention, treatment and diagnosis of PE.
