Deregulation of various components of the immune system has been reported in the inflamed gut of Crohn's disease (CD) patients. Innate lymphoid cells (ILCs) are novel innate effector lymphocytes which can rapidly respond to danger signals, from invading pathogens or tissue damage, to maintain homeostasis, especially along the mucosal surfaces. The purpose of this study is to compare composition of the intestinal ILCs subsets of CD patients with differential inflammatory conditions of the terminal ileum, which are marked by distinct histological appearances and mucosal profiles of cytokines. We observed alterations in the frequency of Lineage(-)CRTH2(-)CD45(+)NKp44(-)CD117(-)CD127(+)ILC subset in the inflamed terminal ileum.

Background: Individuals with severe obesity and type 2 diabetes mellitus have reduced secretion of incretins by L cells. Studies suggest an increase in L cell activity according to the length of the Biliopancreatic Loop (BPL).
Objective: Compare the effect of biliopancreatic loop extension on the number and expression of L cells in patients undergoing RYGB METHODS: Subjects (n = 13) undergoing RYGB with a BPL of 100 cm (G1) or 200 cm (G2).

Total proctocolectomy with ileal pouch anal anastomosis is the standard of care for patients with severe ulcerative colitis. We generated a cell-type-resolved transcriptional and epigenetic atlas of ileal pouches using scRNA-seq and scATAC-seq data from paired biopsy samples of the ileal pouch and the ileal segment above the pouch (pre-pouch) from patients (male=4, female=2), and paired biopsies of the terminal ileum and ascending colon from healthy individuals (male=3, female=3) serving as reference. Our study finds an additional population of absorptive and secretory epithelial cells within the pouch but not the pre-pouch.

Introduction: The current understanding of colorectal carcinogenesis is based on the adenoma-carcinoma sequence, where genetics, intestinal microbiota changes and local immunity shifts seem to play the key roles. Despite the emerging evidence of dysbiotic intestinal state and immune-cell infiltration changes in patients with colorectal adenocarcinoma, early and advanced adenoma as precursors of colorectal cancer, and carcinoma as the following progression, are rather less studied. The newly colon-site adapted AI-based analysis of immune infiltrates is able to predict long-term outcomes of colon carcinoma.

Purpose: Pediatric-onset Crohn's disease (CD) presents with a more aggressive course than adults. Surgical treatment is still necessary in many patients. The laparoscopic technique for treating terminal ileal CD is deemed safe and feasible, with the advantage to perform an intra-corporeal anastomosis (ICA).
