- 对接受小鼠肠道微生物群组成和血清炎症标志物的分析.
- 集成老鼠和人类测序数据以识别IgAV相关细菌.
主要成果:
- 与健康微生物群 (rHMb) 相比,具有IgAV微生物群 (rIMb) 的接受者小鼠表现出不同的微生物特征.
- 与HC相比,在rIMb小鼠和患有IgAV的儿童中观察到Alcaligenaceae丰度的显著下降.
- 在rIMb小鼠中,高水平的促炎细胞因子 (IL-17A,IL-21) 与肠道微生物群变化和IgA相关.
结论:
- IgAV的特征是肠道微生物群失调和炎症性细胞因子失衡.
- 类植物的丰富性可以作为区分IgAV患者的潜在生物标志物.
- 调节肠道微生物群是IgAV预防和治疗的有希望的治疗策略.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease II: Crohn's Disease
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.
