1、摘要結(jié)論:1.本研究建立以BSA+CCl4+LPS誘導(dǎo)的大鼠IgAN模型,并發(fā)現(xiàn)TIM-1mRNA的表達(dá)上調(diào),且與IgAN大鼠的24尿蛋白定量,腎臟病理組織學(xué)損傷程度正相關(guān),提示TIM-1信號通路可能參與大鼠IgAN的發(fā)病及進(jìn)展。2.IgAN大鼠腎組織中TIM-1與IL-4表達(dá)均上調(diào)并呈正相關(guān),提示TIM-1信號通路可能參與調(diào)控Th2優(yōu)勢反應(yīng),而參與IgAN的發(fā)病。3.IgAN大鼠腎組織中TIM-1的表達(dá)與IFN-γ/IL-4表達(dá)呈負(fù)相關(guān),提示TIM-1信號通路可能通過調(diào)控Th1/Th2平衡來參與IgAN的發(fā)病。關(guān)鍵詞:IgA腎病;TIM-1;IL-4;IFN-
