Advances in the research of intestinal fungi in Crohn's disease

Abstract

This article reviews of the original research published by Wu et al in the World Journal of Gastroenterology, delving into the pivotal role of the gut microbiota in the pathogenesis of Crohn's disease (CD). Insights were gained from fecal microbiota transplantation (FMT) in mouse models, revealing the intricate interplay between the gut microbiota, mesenteric adipose tissue (MAT), and creeping fat. The study uncovered the characteristics of inflammation and fibrosis in the MAT and intestinal tissues of patients with CD; moreover, through the FMT mouse model, it observed the impact of samples from healthy patients and those with CD on symptoms. The pathogenesis of CD is complex, and its etiology remains unclear; however, it is widely believed that gut microbiota dysbiosis plays a significant role. Recently, with the development and application of next-generation sequencing technology, research on the role of fungi in the pathogenesis and chronicity of CD has deepened. This editorial serves as a supplement to the research by Wu et al who discussed advances related to the study of fungi in CD.
