まとめ
炎症性腸疾患 (IBD) 研究は,動物研究を超えて,ますます高度なヒト由来モデルを使用しています. これらの新しいプラットフォームは,IBD治療の翻訳を改善するために,免疫-マイクロバイオームの相互作用をより良く表します.
科学分野:
- 胃腸内科と免疫学について
- 翻訳医学は翻訳医学である.
- マイクロバイオーム研究
背景:
- クローン病や潰瘍性大腸炎を含む炎症性腸疾患 (IBD) は,世界的な流行率が上昇している慢性疾患です.
- 伝統的な臨床前IBDの研究は,疾患のメカニズムを研究し,治療法をテストするために動物モデルに大きく依存しています.
- 腸内微生物群のディスバイオシスは,IBDの発症,進行,および治療への反応の重要な要因として認識されています.
研究 の 目的:
- 炎症性腸疾患 (IBD) の既存の動物モデルを批判的に評価する.
- IBDにおける免疫-マイクロバイオーム-表皮の相互作用を表現する現在のモデルの能力を評価する.
- IBD研究のための補完的な翻訳的ツールとして,新興の人間に由来する in vitro プラットフォームについて議論する.
主な方法:
- 炎症性腸疾患 (IBD) 研究で使用されている既存のインビヴォ動物モデルのレビュー.
- 免疫-微生物群の相互作用を含む,主要なIBD特性を再現するこれらのモデルの能力の評価.
- オーガノイドやgut-on-chip技術など,人間から派生した新しいインビトロシステムの議論.
主要な成果:
- 動物モデルはIBD研究において重要な役割を果たしてきたが,種間差異と制限された翻訳的予測性に苦しんでいる.
- 既存のモデルは,しばしば,IBDに不可欠な複雑な腸内微生物群と宿主免疫相互作用を完全に表現することができません.
- 人間に由来する新興のin vitroプラットフォームは,IBDを研究するために,より人間に関連したモデルを提供しています.
結論:
- オーガノイドやgut-on-chipシステムを含む先進的なin vitroモデルは,IBDにおける臨床前発見と臨床応用の間のギャップを埋める上で極めて重要です.
- マイクロバイオーム応答性および免疫能力のあるインビトロモデルを統合することは,将来のIBD研究のための有望な戦略です.
- 人間に関連したプラットフォームを通じて動物モデルへの依存を減らすことは,規制の動向と整合し,IBDの翻訳的成功を高めます.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
950
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Irritable Bowel Syndrome I: Introduction
1.2K
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:

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.

Inflammatory Bowel Disease I: Ulcerative Colitis
1.2K
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
