TNF-α and IFN-γ Synergistically Stimulate Mesenchymal Stem Cell Exacerbated DSS-induced Mice Colitis and Inflammatory Responses Via NF-κB /STAT3 Signalings

Abstract

炎症性肠病(IBD),尤其是溃疡性结肠炎(UC)的在中国的发病率越来越高,直接影响人们的正常生活并增加了患癌症的几率,但它的发病机制尚不明确。目前研究发现UC的发病机制与肠道菌群失调、肠道粘膜功能障碍、肠道内分化的免疫调节功能障碍等有关,尤其是肠道免疫失调和信号通路的改变引起了特别关注。对IBD的治疗手段也在不断的更新,其中TNF-α抑制剂的使用,引起了我们的关注。另外,因为骨髓间充质干细胞(MSCs)具有高分化能力、低免疫原性、调节免疫系统、归巢机体损伤部位和肿瘤等方面的优势而已经使用于临床治疗。也已有文献提示MSCs能够通过调节肠炎小鼠的免疫系统而对小鼠肠炎进行损伤修复,但MSCs具体的作...In recent decades, ulcerative colitis (UC) is considered a type of inflammatory bowel disease (IBD), which can affect the peoples’ normal life and that is increased the probability of the colon carcinogenesis. The exact pathogenesis of this disease is still unknown. It characterized by continuous mucosal inflammation extending proximally from the rectum, the immunoregulatory dysfunction of intest...学位:理学硕士院系专业:医学院_药理学学号:2452011115334
