概括
这项研究确定了多发性硬化症 (MS) 和炎症性肠病 (IBD) 中共享的炎症基因和通路. 细胞因子信号传递3 (SOCS3) 和甲基受体2 (FPR2) 的抑制剂成为这两种疾病的潜在诊断生物标志物.
科学领域:
- 免疫学和遗传学
- 自身免疫性疾病的研究.
- 生物信息学和系统生物学
背景情况:
- 多发性硬化症 (MS) 和炎症性肠病 (IBD) 是自身免疫性疾病,并具有越来越多的并发性疾病.
- 在MS和IBD之间共享的病理生理机制在很大程度上仍未定义.
- 了解共同的分子基础对于开发向疗法至关重要.
研究的目的:
- 确定MS和IBD中共享的差异性表达基因 (DEG) 和途径.
- 研究这些共享基因在免疫细胞群中的作用.
- 发现MS和IBD的潜在诊断生物标志物.
主要方法:
- 分析IBD和实验性过敏脑膜炎 (EAE) 的多重RNA测序数据集作为MS模型.
- 单细胞RNA测序和质量细胞测量 (CyTOF) 用于表征免疫细胞概况.
- 机器学习算法用于生物标记物识别.
主要成果:
- 确定了74种常见的DEG,其中56种与炎症相关的IRG在IBD和EAE/MS中都高度丰富于IL1B+巨细胞.
- 这些IRG与关键的炎症途径有关,包括IL-17,NF-kappa B和TNF信号传递.
- 细胞因子信号传递3 (SOCS3) 和甲基受体2 (FPR2) 的抑制剂被确定为潜在的生物标志物,在炎症性巨细胞中具有高表达.
结论:
- 共享的炎症基因,特别是那些表达在亲炎性巨细胞中的基因,在IBD和MS的发病过程中起着重要作用.
- SOCS3和FPR2显示为MS和IBD的诊断生物标志物具有前途.
- 这项研究提供了关于这些独特的自身免疫性疾病背后的常见免疫失调的见解.

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

315
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
