まとめ
このレビューでは,臓器特異的な自己免疫疾患の患者で腸内細菌Subdoligranulumのレベルが低いことが判明しました. これらの発見は,サブドリグラヌラムと自己免疫疾患の発症との関連を示唆しています.
科学分野:
- 腸内微生物群の研究
- 免疫学
- 微生物の病原性
背景:
- 自己免疫疾患は 腸内微生物の変化と 腸内障壁の機能不全を 共有しています
- 腸内細菌のサブドリグラヌラムは 局所的な腸内炎症に関与しています
- Subdoligranulumの役割を理解することは,自己免疫疾患の研究にとって極めて重要です.
研究 の 目的:
- サブドリグラヌラムと自己免疫疾患の関係を体系的に検討する.
- 各種の自己免疫疾患におけるサブドリグラヌラム濃度の変化を評価する.
- サブドリグラヌラムと炎症マーカーの関連性を調べる
主な方法:
- パブメド,コクラン,Web of Science,Embaseの体系的な文献検索
- 患者と健康な対照群のサブドリグラヌラム濃度を比較したメタ分析.
- 異なる治療によるサブドリグラヌラムの変化とバイオマーカーとの相関性の分析
主要な成果:
- 1,792人の参加者を含む12件の研究が含まれた.
- コントロール群と比較して,ほとんどの自己免疫疾患の患者でサブドリグラヌラム値の低下が観察された (p=0. 027).
- サブドリグラヌラムはCRP,LBP,Treg細胞と正の相関関係があり,IL-8と負の相関関係があった.
結論:
- 臓器特異の自己免疫疾患では,サブドリグラヌルムの豊富さは減少している.
- 系統的自己免疫疾患では,Subdoligranulumに一貫した変化は見られなかった.
- サブドリグラヌルムの変異は,自己免疫疾患の病原化に寄与する可能性があります.

Autoimmune Disorders
671
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.

Chronic Bowel Disorders: Introduction
540
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
