The cellular mediators of intestinal fibrosis and the relationship between fibrosis and normal repair are not understood. Identification of the types of intestinal mesenchymal cells that produce collagen during normal healing and fibrosis is vital for elucidating the answers to these questions. Acute injury may cause normal mesenchymal cells to convert to a fibrogenic phenotype that is not main...
Inflammatory bowel disease, mainly Crohn's disease and ulcerative colitis, are characterized by epithelial barrier disruption and altered immune regulation. Colonic Ste20-like proline/alanine-rich kinase (SPAK) plays a role in intestinal inflammation, but its underlying mechanisms need to be defined. Both SPAK-transfected Caco2-BBE cells and villin-SPAK transgenic (TG) FVB/6 mice exhibited loss...
Quercitrin is a flavonoid with antiinflammatory activity in experimental colitis, associated with an antioxidative action and amelioration of water absorption in vivo. However, its mechanism of action is unclear. This study focuses on the effect of quercitrin (1 and 5 mg/kg) in the early stages (24 h) of trinitrobenzene sulfonic acid colitis. Treatment with the flavonoid prevented the increase ...
Transforming growth factor-beta2-treated Ag-pulsed APC mimic APC from the immune privileged eye, and provide signals that generate regulatory T (Tr) cells and mediate peripheral tolerance. We postulated that TGF-beta2-treated Ag-pulsed APC (tolerogenic APC (tol-APC)) might also orchestrate regulation of immune mediated pathogenesis in nonimmune privileged tissues such as the lung. We used an ad...
Chemokines have well characterized proinflammatory actions, including the ability to induce extravasation of leukocytes that participate in chronic inflammation. In this study, we evaluated the role of a C-C chemokine, RANTES, in the chronic phase of a rat model of colitis. Colitis was induced by intracolonic administration of trinitrobenzene sulfonic acid. At various timepoints thereafter (2 h...
Calcitonin gene-related peptide (CGRP) mediates neurogenic inflammation and modulates intestinal motility. The CGRP receptor is a heterodimer of calcitonin receptor-like receptor (CLR) and receptor-associated modifying protein 1. We used RNA interference to elucidate the specific role of CLR in colonic motility and inflammation. Intramural injection of double-stranded RNA (dsRNA) against CLR (d...
OBJECTIVES : Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely prescribed for the treatment of pain in chronic pancreatitis (CP). This study aimed to investigate the effect of NSAIDs on the inflammation and fibrosis progression in trinitrobenzene sulfonic acid-induced CP rats. METHODS Chronic pancreatitis was induced by trinitrobenzene sulfonic acid infusion into rat pancreatic ducts. ...
