Background and objectives: TLR2, TLR4, and Dectin-1 (Clec7) are pattern recognition receptors (PRRs) expressed by intestinal epithelia cells and MYD88 is a signaling molecule of TLR2 and TLR4.  They warn immune system about the presence of invading pathogens promoting initiation of inflammatory response. Because of colonic cancer risk, therapy of intestinal inflammation is of h...

ABSTRACT The objective of this study was to develop a novel subgingival sustained-release system for local delivery bioactive minocycline hydrochloride periodontal disease treatment in dogs. incorporated the Minocycline hydrochloride-Calcium-Dextran sulfate sodium into thermoresponsive Pluronic F127 hydrogel. sustained release from up 10 days and kinetics fit power law model. medium had signifi...

The aim of this study is to assess the preventive effects of Lactobacillus fermentum HY01 (LF-HY01) to dextran sulfate sodium induced-colitis. We observed the ratio of colon weight to its length, colon pathological changes, and the concentrations of pro-inflammatory factors (IFN-γ, IL-12, TNFα, and IL-6) in serum. We also took account of the protein levels of IκBα, NF-κB p65, iNOS, and COX-2, a...

Eosinophil migration into the gut and the release of granular mediators plays a critical role in the pathogenesis of inflammatory bowel diseases, including ulcerative colitis. We recently demonstrated that eosinophil migration into the lung requires cell surface expression of the sialomucin CD34 on mast cells and eosinophils in an asthma model. Based on these findings, we investigated a similar...

The specific type IV phosphodiesterase inhibitor rolipram is a potent suppressor of tumor necrosis factor-alpha (TNF) synthesis. We examined the efficacy of rolipram for the prevention and treatment of experimental colitis. To induce colitis, BALB/c mice received 5% dextran sulfate sodium in their drinking water continuously for up to 11 days. Colitis was quantified by a clinical activity score...
