Results suggest that endogenous H2S is an important mediator of acute inflammation, acting at the leukocyte‐endothelium interface, and have important implications for anti‐inflammatory drug development.
Inhibition of hydrogen sulfide generation contributes to gastric injury caused by anti-inflammatory nonsteroidal drugs.
These data establish a physiologic role for H(2)S in regulating the gastric microcirculation and identify CSE as a novel target for ASA/NSAIDs.

It is demonstrated that FXR is expressed by and exerts counterregulatory effects on cells of innate immunity and regulates inflammation in animal models of colitis, and that in vivo treatment with INT-747 attenuates organ injury and immune cell activation.

Bile Acids Activated Receptors Regulate Innate Immunity
How GPBAR1 and FXR modulate the intestinal and liver innate immune system and contribute to the maintenance of a tolerogenic phenotype in entero-hepatic tissues is reviewed and how regulation of innate immunity might help to explain beneficial effects exerted by GPB BAR1 andFXR ligands in immune and metabolic disorders is reviewed.
The emerging roles of hydrogen sulfide in the gastrointestinal tract and liver.
Evidence has accumulated to suggest important roles for hydrogen sulfide as a mediator of several aspects of gastrointestinal and liver function, and inhibitors of hydrogen sulfides synthesis and drugs that can generate safe levels in vivo have been developed and are permitting interventional studies in experimental models and, in the near future, humans.

Modulation of gut microbiota represents a new strategy for the treatment of irritable bowel syndrome and probiotics appear an attractive option in terms of both efficacy and safety, while prebiotics, synbiotics and antibiotics still need confirmation.
Evidence That Hydrogen Sulfide Exerts Antinociceptive Effects in the Gastrointestinal Tract by Activating KATP Channels
Data show that H2S inhibits nociception induced by CRD in both healthy and postcolitic rats, and this effect is mediated by KATP channels and NO.
The Bile Acid Receptor GPBAR-1 (TGR5) Modulates Integrity of Intestinal Barrier and Immune Response to Experimental Colitis
GP-BAR1 regulates intestinal barrier structure and expression increases in rodent models of colitis and Crohn's disease and ciprofloxacin is a GP-Bar1 ligand.
Probiotics Modulate Intestinal Expression of Nuclear Receptor and Provide Counter-Regulatory Signals to Inflammation-Driven Adipose Tissue Activation
Mesenteric adipose tissue from rodent colitis and Crohn's disease is metabolically active and shows inflammation-driven regulation of PPARγ, FXR and leptin, and probiotics correct the inflammation- driven metabolic dysfunction.
