JAK2/STAT3信號轉(zhuǎn)導通路在門靜脈高壓大鼠模型脾臟纖維化過程中的作用
發(fā)布時間:2022-02-10 15:36
脾腫大是門脈高壓癥的重要并發(fā)癥之一[1]。據(jù)統(tǒng)計,大約36%-92%的肝硬化患者存在著不同程度脾臟腫大[2],特別是在我國,乙型病毒性肝炎導致的失代償期肝硬化是引起脾腫大的主要原因之一[3],嚴重危害著患者的生命健康。門脈高壓性脾臟腫大可以產(chǎn)生一系列的并發(fā)癥[4-5]:1、壓迫腹腔周圍臟器產(chǎn)生相應癥狀;2、脾功能亢進導致貧血;3、導致機體免疫功能下降;4、可能因輕微碰撞而發(fā)生破裂出血;5、機體儲血能力下降等。纖維組織增生是門脈高壓癥脾臟腫大的重要原因之一,也是其主要病理特征之一。JAK2/STAT3信號轉(zhuǎn)導通路是一條多種細胞因子參與的信號轉(zhuǎn)導途徑,最初因為參與細胞增殖而被發(fā)現(xiàn),在后續(xù)的研究中發(fā)現(xiàn)該信號轉(zhuǎn)導通路與機體的多種組織器官的細胞分化、凋亡、免疫功能改變等密切相關[6]。有研究表明該信號轉(zhuǎn)導通路可能參與機體組織器官的纖維化過程[7-12]。在腎間質(zhì)纖維化過程中JAK2/STAT3信號轉(zhuǎn)導通路被激活提示該通路可能參與了組織纖維化。JAK2/STAT3信號轉(zhuǎn)導通路還通過調(diào)節(jié)多種細胞因子促進血管平滑肌細胞和成纖維細胞增生、遷移。既往研究表明JAK2/STAT3信號轉(zhuǎn)導通路在組織纖維化過程...
