Zusammenfassung
Aktuelle Forschungsergebnisse zeigen, dass das intestinale Mikrobiom, die Gesamtheit aller intestinalen Mikroorganismen und ihrer Gene, eine wichtige Rolle für die Gesundheit des Menschen spielt und als eine Art „externes Organ“ betrachtet werden kann. Das intestinale Mikrobiom ist ein komplexes und dynamisches System, das über die Grenzfläche Darm das Immunsystem und den Stoffwechsel des gesamten Organismus beeinflusst. Für die Entwicklung und Aufrechterhaltung der normalen Darmfunktionen sind die Zusammensetzung und Funktionalität der intestinalen Mikrobiota besonders wichtige Faktoren. Chronisch entzündliche Darmerkrankungen (CED) sind durch eine dysregulierte Interaktion zwischen dem Wirtsorganismus und seiner intestinalen Mikrobiota gekennzeichnet. Der vorliegende Beitrag fasst das aktuelle Wissen zum Aufbau und zur Entwicklung des intestinalen Mikrobioms zusammen und gibt einen Einblick in die wechselseitige Interaktion zwischen Wirt und Mikrobiota. Er informiert über die Erkenntnisse zur Rolle des Mikrobioms bei CED und diskutiert im Anschluss das protektive Potenzial mikrobieller Therapien bei CED.
Abstract
Recent scientific results underline the importance of the intestinal microbiome, the totality of all intestinal microbes and their genes, for the health of the host organism. The intestinal microbiome can therefore be considered as a kind of “external organ”. It has been shown that the intestinal microbiota is a complex and dynamic ecosystem that influences host immunity and metabolism beyond the intestine. The composition and functionality of the intestinal microbiota is of major importance for the development and maintenance of intestinal functions. Inflammatory bowel diseases (IBD) are characterized by dysregulated interactions between the host and its microbiota.
The present contribution summarizes current knowledge of the composition and development of the intestinal microbiome and gives an overview of the bidirectional interaction between host and microbiota. The contribution informs about insights regarding the role of the intestinal microbiota in IBD and finally discusses the protective potential of microbial therapies in the context of IBD.
