Sprue-like enteropathy associated with olmesartan medoxomil use has been recently reported. Its clinical manifestations include diarrhea, weight loss and malabsorption. Duodenal biopsies show villous atrophy (VA) with or without intraepithelial lymphocytosis and inflammation of the lamina propria. Serology for celiac disease (CD) is negative and gluten-free diet does not result in clinical improvement. Symptoms resolve after olmesartan discontinuation. Follow-up biopsies show recovery/improvement of the duodenum...

The mouse bitter taste receptors Tas2r143, Tas2r135, and Tas2r126 are encoded by genes that cluster on chromosome 6 and have been suggested to be expressed under common regulatory elements. Previous studies indicated that the Tas2r143/Tas2r135/Tas2r126 cluster is expressed in the heart, but other organs had not been systematically analyzed. In order to investigate the expression of this bitter taste receptor gene cluster in non-gustatory tissues, we generated a BAC (bacterial artificial chromosome) based transgenic mouse line, expressing CreERT2 under the control of the Tas2r143 promoter...

Salmonella typhimurium is a facultative intracellular bacterium that causes gastroenteritis in humans. After invasion of the lamina propria, S. typhimurium bacteria are quickly detected and phagocytized by macrophages, and contained in vesicles known as phagosomes in order to be degraded. Isolation of S. typhimurium-containing phagosomes have been widely used to study how S. typhimurium infection alters the process of phagosome maturation to prevent bacterial degradation. Classically, the isolation of bacteria-containing phagosomes has been performed by sucrose gradient centrifugation...

Telocytes (TC) are the delicate interstitial (stromal) cells defined by their long, thin and moniliform processes termed telopodes. Numerous studies determined that different subsets of telocytes populate almost all tissues and attempted to relate these subsets to various functions, from cell signaling to tissue repair and regeneration. Extremely few studies addressed the urinary tract though few data on the molecular pattern of the urinary TCs actually exist. We therefore hypothesized that subsets of urinary TCs co-localize within the human ureter and we aimed at performing an immunohistochemical study to evaluate the tissue-specific molecular pattern of TCs...

Pathological manifestations in rainbow trout (Oncorhynchus mykiss) following experimental waterborne infection with Yersinia ruckeri serotype O1 biotype 2 (strain 07111224) were investigated. Rainbow trout were exposed to 8 × 10(7)  CFU/ml of Y. ruckeri by bath for 6 hr, and mortality was then monitored for 22 days post-infection (dpi). Organs were sampled at 3 dpi and also from moribund fish showing signs of severe systemic infection such as bleeding, exophthalmia or erratic swimming behaviour. Y. ruckeri was observed in the meninges and diencephalon of the brain, and lamina propria of olfactory organ at 3 dpi...

Naive CD4 T cells activated by antigen-presenting cells (APCs) undergo terminal differentiation in the periphery. Multiple mechanisms determine their fates, that is, whether they differentiate into conventional T (Tconv) cells or regulatory T (Treg) cells. The key event during Treg generation is expression of the transcription factor Foxp3, which is the lineage-determining regulator for Treg differentiation and function. Here we show that the transcription factor Batf3 acts as a fate-decision factor with respect to Tconv versus Tregs by restraining Treg differentiation...

Perturbations of the intestinal microbiome have been observed in patients with new-onset and chronic autoimmune inflammatory arthritis. However, it is currently unknown whether these alterations precede the development of arthritis or are rather a consequence of disease. Modulation of intestinal microbiota by oral antibiotics or germ-free condition can prevent arthritis in mice. Yet, the therapeutic potential of modulation of the microbiota after the onset of arthritis is not well characterized. We here show that the intestinal microbial community undergoes marked changes in the preclinical phase of collagen induced arthritis (CIA)...

OBJECTIVE: The aim of this study was to evaluate the outcomes of endoscopic submucosal dissection (ESD) for superficial proximal esophageal neoplasia. SUMMARY OF BACKGROUND DATA: The surgery for a tumor located in proximal esophagus is relatively difficult and leads to a high morbidity and mortality. ESD is a minimally invasive endoscopic treatment of superficial neoplasia of the gastrointestinal tract allowing en block resection with low recurrence rates; however, ESD for superficial proximal esophageal neoplasia is little known...

The histochemical distribution of acid phosphatase (ACP), alkaline phosphatase (ALP), non-specific esterase (NSE), peroxidase (POD) and mucous-cell types was evaluated in the gastrointestinal tract of the half-smooth tongue sole Cynoglossus semilaevis. The enzymes were detected in the entire stretch of the gastrointestinal tract. ACP activity was found in the supranuclear region of enterocytes and the lamina propria of the intestine, as well as the cytoplasm of epithelial cells of the stomach. The staining intensity of ACP in the anterior and posterior intestines was stronger than in the stomach...

Sphingolipids regulate critical cellular processes including inflammation. Ceramide, which serves a central role in sphingolipid metabolism, is generated by six ceramide synthases (CerS) that differ in substrate specificity. CerS6 preferentially generates C16-ceramide and its mRNA is highly expressed in immune tissues. In this study we analyzed how deficiency of CerS6 impacts on the development of colitis using an adoptive transfer model. Adoptive transfer of CerS6-deficient splenocytes, which have significantly decreased levels of C16-ceramide, showed that CerS6-deficiency protected against the development of colitis...

BACKGROUND AND AIMS: During active inflammation tissue intraluminal intestinal pH is decreased in patients with inflammatory bowel disease (IBD). Acidic pH may play a role in IBD pathophysiology. Recently, proton sensing G-protein coupled receptors were identified, including GPR4, OGR1 (GPR68), and TDAG8 (GPR65). We investigated whether GPR4 is involved in intestinal inflammation. METHODS: The role of GPR4 was assessed in murine colitis models: chronic dextran sulphate sodium (DSS) administration and by crossbreeding into an IL-10 deficient background for development of spontaneous colitis...

To better understand the innate immune response to Vibrio cholerae infection, we tracked gene expression in the duodenal mucosa of eleven Bangladeshi adults with cholera, using biopsies obtained immediately after rehydration and at 30 and 180 days later. We identified differentially expressed genes and performed an analysis to predict differentially regulated pathways and upstream regulators. During acute cholera, there was a broad increase in the expression of genes associated with innate immunity, including activation of the NF-κB, MAPK, and TLR-mediated signaling pathways, which unexpectedly persisted even 30 days after infection...

BACKGROUND/AIMS: Intestine-derived endotoxin is thought to play a role in the development of liver fibrosis. However, the pathological change in the intestine during liver fibrosis is still poorly understood. Here, we investigated the effects of Xia-yu-xue decoction (XYXD) on intestinal inflammation, apoptosis, and tight junction integrity in the carbon tetrachloride (CCl4)-induced liver fibrosis. METHODS: Murine liver fibrosis was developed by CCI4 treatment three times per week over a 6-week period...

The aim of our study was to analyse the possible protective effect of quercetin application during the jejunal ischemia-reperfusion injury (IRI) in rats. Quercetin was administered intraperitoneally 30min before 1h ischemia of superior mesenteric artery with following 24h lasting reperfusion period. The male specific pathogen-free (SPF) Charles River Wistar rats were used. In the group with applied quercetin, the significantly increased (p<0.001) levels of anti-inflammatory cytokine IL10 were observed both in the blood serum and jejunal tissue...

The effect of oral administration of probiotic bacteria cell walls (PBCWs) in the stimulation of the immune system in healthy BALB/c mice was evaluated. We focused our investigation mainly on intestinal epithelial cells (IECs) which are essential for coordinating an adequate mucosal immune response and on the functionality of macrophages. The probiotic bacteria and their cell walls were able to stimulate the IECs exhibiting an important activation and cytokine releases. Supplementation with PBCWs promoted macrophage activation from peritoneum and spleen, indicating that the PBCWs oral administration was able to improve the functionality of the macrophages...

Nerve endings with immunoreactivity for the P2X3 purinoreceptor (P2X3) in the rat tracheal mucosa were examined by immunohistochemistry of whole-mount preparations with confocal scanning laser microscopy. P2X3 immunoreactivity was observed in ramified endings distributed in the whole length of the trachea. The myelinated parent axons of P2X3-immunoreactive nerve endings ramified into several branches that extended two-dimensionally in every direction at the interface between the epithelial layer and lamina propria...

Cow's milk allergy (CMA) prevails in infants and brings increased risk of developing other allergic diseases. Oral administration of specific β-lactoglobulin (BLG)-derived peptides (PepMix) and a specific blend of short- and long-chain fructo-oligosaccharides and Bifidobacterium breve M-16V (FF/Bb) was found to partially prevent CMA development in mice. In this study, we aimed to expand the knowledge on the preventive potential and the underlying mechanisms of this approach. Three-week-old female C3H/HeOuJ mice were orally exposed to PepMix±FF/Bb prior to a 5-week oral sensitization with whole whey and cholera toxin as an adjuvant...

Vibrio vulnificus (V. vulnificus) is a gram-negative bacterium, which causes life-threatening septicemia and gastroenteritis through the consumption of contaminated seafood or wound infection. In addition, V. vulnificus infection is known to stimulate the production of several pro-inflammatory cytokines, which are associated with inflammatory responses mediated predominantly by dendritic cells (DCs), functioning as antigen-presenting cells. The present study aimed to investigate whether V. vulnificus infection induced the maturation and activation of murine DCs, which have the ability to polarize T helper (Th) cells into Th17 cells...
