Commensal bacteria protect against food allergen sensitization

(Submitter supplied) Analysis of colonic epithelial cell gene expression in germ-free, Bacteroides uniformis-colonized, and Clostridia-colonized gnotobiotic mice. Bacteria were isolated from our SPF mouse facility and were used to selectively colonize germ-free mice.

Commensal bacteria colonization effect on gnotobiotic model of food allergy: colonic epithelial cells

Analysis of intestinal epithelial cells (IECs) from gnotobiotic animals selectively colonized with Bacteroides uniformis or Clostridia. Results provide insight into the role of microbial interactions with IECs in protecting against sensitization to food allergens.

Microbiota facilitates dietary heme-induced epithelial hyperproliferation and hyperplasia by breaking the mucus barrier

(Submitter supplied) Colorectal cancer risk is associated with diets high in red meat. Heme, the pigment of red meat, induces cytotoxicity of colonic contents and elicits epithelial damage and compensatory hyperproliferation, leading to hyperplasia. Here we explore the possible causal role of the gut microbiota in heme-induced hyperproliferation. To this end, mice were fed a purified control or heme diet (0.5 μmol/g heme) with or without broad-spectrum antibiotics for 14 d. more...
