The intestinal microbiota has become a relevant aspect of human health. Microbial colonization runs in parallel with immune system maturation and plays a role in intestinal physiology and regulation. Increasing evidence on early microbial contact suggest that human intestinal microbiota is seeded before birth. Maternal microbiota forms the first microbial(More)
The mucus layer covering the gastrointestinal (GI) epithelium is critical in selecting and maintaining homeostatic interactions with our gut bacteria. However, the underpinning mechanisms of these interactions are not understood. Here, we provide structural and functional insights into the canonical mucus-binding protein (MUB), a multi-repeat cell-surface(More)
BACKGROUND & AIMS beta3 Adrenoceptor (beta3-AR) is expressed on adipocytes and enteric neurons. GW427353 is a human selective beta3-AR agonist with visceral analgesic effects. Some of its effects may involve release of somatostatin (SST) and actions on enteric neurons. The aim of this study was to investigate the mode of action of GW427353 in human(More)
Intestinal homeostasis is maintained by a hierarchy of immune defenses acting in concert to minimize contact between luminal microorganisms and the intestinal epithelial cell surface. The intestinal mucus layer, covering the gastrointestinal tract epithelial cells, contributes to mucosal homeostasis by limiting bacterial invasion. In this study, we used γδ(More)
Intestinal γδ T-cell receptor-bearing intraepithelial lymphocytes (γδ IELs) play a multifaceted role in maintaining mucosal homeostasis. In order to investigate the relationship between O-glycosylation and inflammation, we carried out an in-depth mass spectrometric comparison of the intestinal O-glycosylation profile of mice lacking γδ IELs (TCRδ(-/-)) and(More)
