概括

这项研究发现肠道细菌和关节炎之间存在因果关系,特定的细菌和炎症性蛋白质,如白素-7增加了结性脊柱炎的风险. 调节肠道微生物群可能提供一种新的关节炎治疗策略.

科学领域:

微生物学微生物学
免疫学免疫学免疫学
遗传学是一个遗传学.

背景情况:

新出现的证据表明,肠道微生物群组成和关节炎发展之间存在联系.
然而,确切的因果关系和炎症蛋白在这种关联中的作用在很大程度上仍未被阐明.
了解这些联系对于开发各种形式关节炎的新型治疗策略至关重要.

研究的目的:

研究肠道微生物群,炎症蛋白和四种主要类型的关节炎之间的因果关系:骨关节炎,类风湿性关节炎,牛皮性关节炎和性脊柱炎 (AS).
探索炎症蛋白在肠道微生物群-关节炎通路中的潜在调解作用.
为了识别特定的微生物种群和与关节炎亚型因果相关的炎症标记物.

主要方法:

利用孟德尔随机化 (MR) 分析,一种强大的遗传流行病学方法,推断因果关系.
采用逆方差加权 (IVW) 方法作为主要的分析方法.
进行敏感性分析以确保发现的可靠性和丰富性分析以探索潜在的生物途径.

主要成果:

确定了肠道微生物群遗传责任和关节炎之间的显著因果关系,有11个正面和14个负面关联.
在炎症蛋白和关节炎之间发现了9个正面和8个负面的因果关系.
具体来说,Bacillales序列的丰富性增加和高interleukin-7水平显著与结性脊髓炎 (AS) 的风险增加有关.
已经证明,互白素-7部分调解了Bacillales序列对AS的影响,占因果途径的13.8%.

结论:

建立了肠道微生物群,特定的炎症蛋白质和四种不同类型的关节炎之间的因果关系.
突出了肠道微生物群作为关节炎管理的有希望的治疗点.
表明,准肠道微生物群来调节炎症蛋白质,如介素-7,可能是AS和潜在的其他关节炎形式的可行的治疗策略.

关键词:

结性脊柱炎是一种疾病.关节炎是一种关节炎.我们的肠道微生物群.炎症性蛋白质是一种炎症性蛋白质.介质素-7- 介质素-7 是一种门德尔的随机化

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

The JAK-STAT Signaling Pathway

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
