- 遗传流行病学 遗传流行病学
- 类风湿病学 类风湿病学
背景情况:
- 风湿性关节炎 (RA) 是一种普遍的风湿性疾病,受遗传和环境因素的影响.
- 空气污染和RA之间的关联仍然是持续辩论的主题.
- 研究空气污染的作用对于全面了解RA风险因素和临床管理至关重要.
研究的目的:
- 评估各种空气污染物对类风湿性关节炎 (RA) 的潜在因果作用,使用跨民族孟德尔随机化方法.
- 分析特定空气污染物 (PM2.5,PM2.5-10,PM10,二氧化,氧化) 和RA之间的遗传预测的因果关系.
- 为改善预防和治疗策略提供有关RA环境决定因素的见解.
主要方法:
- 采用双样本孟德尔随机化 (MR) 设计,利用大规模的全基因组关联研究 (GWAS) 数据.
- 欧洲和东亚人口的空气污染暴露和RA病例/对照的综合公开可用的GWAS数据.
- 使用逆方差权衡 (IVW) 作为主要分析方法,使用MR-Egger,权重中位数和权重模式作为灵敏度分析. 使用Cochran的Q和MR-Egger回归分别评估异质性和性. 进行了强度的留下一个漏洞分析.
主要成果:
- 在欧洲或东亚人群中,没有观察到PM2.5,PM2.5-10,PM10,二氧化或氧化对RA的统计学上显著的遗传预测因果作用.
- 欧洲数据的具体结果显示没有显著的关联 (例如,PM2.5 IVW OR:0.71,p=0.498).
- 对于东亚数据的具体结果也表明没有显著的关联 (例如,PM2.5 IVW OR:1.16,p=0.086;二氧化 IVW OR:0.87,p=0.051).
- 敏感性分析,包括MR-Egger,MR-PRESSO和Cochran's Q,没有检测到显著的异质性或质性,而离开一个的分析证实了这些发现的稳定性.
结论:
- 跨民族孟德尔随机化分析表明,暴露于常见空气污染物和类风湿性关节炎之间缺乏遗传预测的因果关系.
- 这些发现有助于关于RA环境风险因素的持续讨论,表明遗传倾向可能与空气污染水平无因果关系.
- 进一步的研究可能是有必要的,以探索其他潜在的环境或基因环境相互作用在RA的病因学.

Genome-wide Association Studies-GWAS
13.2K
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.

The JAK-STAT Signaling Pathway
8.7K
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...

Autoimmune Disorders
395
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Asthma-I: Introduction
2.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
