科学领域:

微生物组研究的研究.
免疫皮肤学免疫皮肤学
遗传流行病学遗传流行病学

背景情况:

人们越来越认识到肠道微生物群 (GM) 与牛皮 (Ps) 和牛皮性关节炎 (PsA) 之间的联系.
然而,基因转基因与这些疾病之间确定的因果关系仍然未确立.

研究的目的:

调查肠道微生物群与牛皮和牛皮性关节炎的发展之间的因果关系.
确定与增加或减少Ps和PsA风险相关的特定细菌种群.

主要方法:

从MiBioGen研究中利用了与转基因相关的遗传变异 (n=18,340).
采用孟德尔随机化 (MR) 分析与反向差异加权.
利用FinnGen数据库获取Ps (4510例) 和PsA (1637例) 的大规模病例控制数据.

主要成果:

确定了特定的细菌种群作为Ps的风险因素 (例如,乳球菌,鲁米尼克洛斯特里5) 和保护因素 (例如,臭菌).
鉴定出不同的细菌种群作为PsA的风险因素 (例如,乳球菌,阿克尔曼西亚) 和保护因素 (例如,臭虫菌,瑞肯氏菌).

结论:

建立了肠道微生物群组成和牛皮和牛皮性关节炎的病变发生之间的因果关系.
这些发现表明,针对Ps和PsA治疗的肠道微生物组,可以提出新的治疗策略.

Irritable Bowel Syndrome I: Introduction

Irritable Bowel Syndrome I: Introduction

Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Mismatch Repair

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...
