摘      要：BACKGROUND Inflammatory bowel disease,particularly Crohn’s disease(CD),has been associated with alterations in mesenteric adipose tissue(MAT)and the phenomenon termed“creeping fat.Histopathological evaluations showed that MAT and intestinal tissues were significantly altered in patients with CD,with these tissues characterized by inflammation and *** To evaluate the complex interplay among MAT,creeping fat,inflammation,and gut microbiota in *** Intestinal tissue and MAT were collected from 12 patients with *** manifestations and protein expression levels were analyzed to determine lesion *** samples were collected from five recently treated CD patients and five control subjects and transplanted into *** intestinal and mesenteric lesions in these mice,as well as their systemic inflammatory status,were assessed and compared in mice transplanted with fecal samples from CD patients and control *** Pathological examination of MAT showed significant differences between CDaffected and unaffected colons,including significant differences in gut microbiota *** microbiota transplantation(FMT)from clinically healthy donors into mice with 2,4,6-trinitrobenzene sulfonic acid(TNBS)-induced CD ameliorated CD symptoms,whereas FMT from CD patients into these mice exacerbated CD ***,FMT influenced intestinal permeability,barrier function,and levels of proinflammatory factors and ***,FMT from CD patients intensified fibrotic changes in the colon tissues of mice with TNBS-induced *** Gut microbiota play a critical role in the histopathology of *** MAT and creeping fat may therefore have potential in the treatment of patients with CD.
