概括
这项研究揭示了肠道微生物群和缺血性中风结果之间的因果关系. 特定的细菌,如Ruminococcaceae UCG005,会对预后产生负面影响,而Lachnospiraceae NK4A136可能会提供保护.
科学领域:
- 微生物学 微生物学
- 神经学 神经学
- 遗传学 是一个遗传学.
背景情况:
- 新兴研究表明,肠道微生物群 (GM) 影响缺血性中风 (IS) 的预后.
- 转基因生物与IS后的功能性结果之间确定的因果关系尚不清楚.
研究的目的:
- 通过使用孟德尔随机化来研究肠道微生物群和缺血性中风后的功能结果之间的因果关系.
- 为了识别特定的肠道微生物种群,因果影响中风预后.
主要方法:
- 利用了来自MiBioGen联盟 (211个转基因种群) 和GISCOME网络 (IS预测) 的汇总级数据.
- 采用了四种门德尔随机化方法来评估因果关系.
- 进行了反向门德尔随机化和比较分析以证实发现.
主要成果:
- 确定了四种与中风预后相关的肠道类型:鲁米诺科卡ceae UCG005和Eubacterium oxidoreducens群 (负效),拉克诺斯皮拉ceae NK4A136群和拉克诺斯皮拉ceae UCG004 (保护作用).

Introduction to the Human Microbiota
222
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

Development of Human Microbiota
68
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

The Oral Microbiota
97
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Gut-Brain Axis
249
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...
