概括
肠道微生物组的变化与动脉样硬化心血管疾病 (ACVD) 有关. 失生症涉及有害细菌的增加和有益的短链脂肪酸 (SCFA) 生产者的减少,影响炎症和新陈代谢.
科学领域:
- 微生物组研究的研究.
- 心血管疾病的研究研究.
- 多领域的整合.
背景情况:
- 动脉样性心血管疾病 (ACVD) 涉及复杂的因素.
- 肠道微生物组的改变越来越多地被认为是ACVD的病原体.
- Carotid 动脉样硬化 (CAS) 作为 ACVD 的一个模型.
研究的目的:
- 在ACVD中综合肠道微生物组变化的证据,使用元基因组学,代谢组学和蛋白质组学.
- 讨论微生物变化及其代谢物在ACVD中的作用,以CAS为例.
- 确定未来的研究方向,以了解因果途径.
主要方法:
- 对现有文献的审查,整合了元基因组学,代谢组学和蛋白质组学数据.
- 对肠道微生物多样性 (α-多样性和β-多样性) 发现的分析.
- 检查特定的细菌种群和与ACVD/CAS相关的微生物衍生代谢物.
主要成果:
- 肠道微生物多样性的证据是混合的,并且根据疾病状况而有所不同.
- 丰富促炎性细菌 (例如,大肠杆菌,克莱布西拉种类) 的丰富. 在ACVD/CAS中观察到的短链脂肪酸 (SCFA) 生产者 (例如,Faecalibacterium prausnitzii) 的减少和耗尽.
- 涉及的关键微生物代谢物包括三甲基胺N-氧化物,SCFA,胆酸和其他物质,可能影响内皮功能,炎症和脂质代谢.
结论:
- 肠道失调有助于ACVD/CAS,可能是通过代谢物介导的途径.
- 代谢物介导的作用包括内皮功能,炎症和脂质代谢.
- 未来的研究应该专注于纵向,干预和多主题研究,以确定因果关系和确定治疗点.

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Physiology of Enteric Nervous System and Gut Health

The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...
