まとめ
腸内細菌叢代謝産物は、免疫応答と腸の健康を厳密に調節します。このレビューでは、それらの機能、治療の可能性、および腸炎治療における課題を探ります。
科学分野:
- 微生物学; 免疫学; 消化器病学
背景:
- 腸内細菌叢代謝産物は、宿主免疫と腸の恒常性の重要な調節因子です。機能不全は、炎症性腸疾患およびその他の腸疾患に関与しています。
研究 の 目的:
- 微生物代謝産物の供給源、機能、免疫調節的役割に関する系統的レビュー。腸炎に対するこれらの代謝産物を標的とする治療戦略の探求。
主な方法:
- 微生物代謝産物に関する文献の系統的レビュー。代謝産物と免疫細胞および炎症経路との相互作用の分析。プロバイオティクス、プレバイオティクス、FMTなどの治療介入の評価。
主要な成果:
- 短鎖脂肪酸、トリプトファン代謝産物、胆汁酸は、免疫細胞(T細胞、B細胞、マクロファージなど)の機能を調節します。代謝産物は、腸管バリアの完全性に影響を与える炎症経路(NF-κB、NLRP3インフラマソーム、JAK-STAT)に影響を与えます。プロバイオティクス、プレバイオティクス、代謝産物投与、FMTは治療の可能性を示しています。
結論:
- 微生物代謝産物は、腸の恒常性と免疫に不可欠です。これらの代謝産物を標的とすることは、腸炎に対する潜在的な個別化治療を提供します。現在の課題を克服するには、さらなる研究とマルチオミクス技術が必要です。

Bacterial Flora of the Large Intestine
1.5K
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Irritable Bowel Syndrome I: Introduction
885
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:

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
