In mice, oral infection induces severe ileitis. The aim of the present study was to investigate the impact of the P2X7 receptor (P2X7) on the inflammatory response to -induced ileitis. Cysts of the ME49 strain of were used to induce ileitis.

Given the role of the P2X7 receptor (P2X7R) in inflammatory bowel diseases (IBD), we investigated its role in the development and progression of colitis-associated colorectal cancer (CA-CRC). CA-CRC was induced in P2X7R and P2X7R mice with azoxymethane (AOM) combined with dextran sodium sulfate (DSS). In a therapeutic protocol, P2X7R mice were treated with a P2X7R-selective inhibitor (A740003).

Microbe-host communication is essential to maintain vital functions of a healthy host, and its disruption has been associated with several diseases, including Crohn's disease and ulcerative colitis, the two major forms of inflammatory bowel disease (IBD). Although individual members of the intestinal microbiota have been associated with experimental IBD, identifying microorganisms that affect disease susceptibility and phenotypes in humans remains a considerable challenge. Currently, the lack of a definition between what is healthy and what is a dysbiotic gut microbiome limits research.

Phenolic compounds (PCs) present in foods are associated with a decreased risk of developing inflammatory diseases. The aim of this study was to extract and characterize PCs from craft beer powder and evaluate their potential benefits in an experimental model of inflammatory bowel disease (IBD). PCs were extracted and quantified from pure beer samples.

Background: Intestinal ischemia-reperfusion (I/R) injury constitutes a severe disorder, in great part resulting from oxidative stress. Because sulforaphane and albumin were shown to increase antioxidant defenses, we evaluated the therapeutic potential of these agents in an experimental model of I/R injury.

Methods: Wistar rats were used to establish a model of intestinal I/R (35 min of ischemia, followed by 45 min of reperfusion) and were treated with albumin (5 mL/kg), sulforaphane (500 μg/kg), or saline intravenously before reperfusion.

Mice orally infected with develop Crohn's disease (CD)-like enteritis associated with severe mucosal damage and a systemic inflammatory response, resulting in high morbidity and mortality. Previously, helminthic infections have shown therapeutic potential in experimental colitis. However, the role of in -induced CD-like enteritis has not been elucidated.
