高盐摄入会改变肠道微生物群, 消耗有益的乳酸菌. 通过调节T助手17 (TH17) 细胞,补充Lactobacillus murinus可以预防盐引起的高血压和自身免疫疾病.
科学领域:
- 微生物组研究
- 免疫学
- 心血管科学
背景情况:
- 高盐摄入与高血压和心血管疾病有关.
- 高盐摄入量可能通过诱导T辅助17 (TH17) 细胞促进自身免疫,从而导致高血压.
- TH17细胞诱导受肠道微生物群的影响,但盐对此的影响尚不清楚.
研究的目的:
- 研究高盐摄入对肠道微生物群的影响.
- 要确定盐是否影响T辅助细胞17 (TH17) 的诱导.
- 探索肠道微生物群调节作为对盐敏感疾病的治疗策略的潜力.
主要方法:
- 用小鼠模型研究高盐摄入对肠道微生物群和TH17细胞群的影响.
- 用Lactobacillus murinus治疗小鼠,以评估其对盐引起的保护作用.
- 一项对人类的试点研究研究了中度高盐对肠道细菌,TH17细胞和血压的影响.
主要成果:
- 在小鼠中,高盐摄入量减少了乳杆菌 (Lactobacillus murinus),并加剧了实验性自身免疫性脑膜炎和对盐敏感的高血压.
- 用L. murinus治疗通过调节TH17细胞来防止这些盐诱导的影响.
- 在人类中,高盐摄入量降低了Lactobacillus spp. 增加的TH17细胞,以及血压升高.
结论:
- 高盐摄入对肠道微生物和免疫系统产生负面影响,特别是TH17细胞反应.
- 乳酸菌可以抵消高盐摄入的有害影响.
- 肠道微生物组是治疗盐敏感性高血压和自身免疫性疾病的潜在目标.

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.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
Inflammatory Response
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
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...
