研究的目的:

调查微生物群和代谢物对DLBCL发展风险的潜在因果影响.
确定可能影响DLBCL发育的特定微生物和代谢因素.

主要方法:

使用孟德尔随机化 (MR) 分析与来自MiBioGen,CLSA和DLBCL GWAS项目的数据集.
使用多种MR方法 (MR-Egger,IVW,加权中位数等) 并进行了反向MR分析.
通过MR-Egger回归,MR-PRESSO,Cochran的Q测试和留出一个分析来评估质,异质性和稳定性.

主要成果:

确定了五种与DLBCL风险相关的微生物,包括*Terrisporobacter*和*Oscillibacter*.
发现了27种与DLBCL有因果关系的血代谢物,特别是酸盐 (保护性) 和甘氨基-N-三氨基-斯芬加迪因 (风险相关).
发现了与DLBCL有因果关系的19种代谢物比率,如氨酸/谷氨酸 (保护性) 和甲胺/胆 (与风险相关).

结论:

这项研究提供了使用MR的微生物群,代谢物和DLBCL之间的因果关系的第一个证据.

Introduction to the Human Microbiota

Introduction to the Human Microbiota

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,...

Microbiota of the Large Intestine

Microbiota of the Large Intestine

The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...
