Carbocisteine is a mucoregulatory drug normalizing sialic acid and fucose contents in mucins through the regulation of glycosyltransferase activities. Tumor necrosis factor (TNF)-alpha-induced overexpression of sialyl-Lewis x epitopes, containing sialic acid and fucose, in mucins were previously
BACKGROUND
Schistosomiasis is a parasitic disease causing chronic ill health in humans with a serious consequences for socio-economic development in tropical and subtropical regions. There is also evidence linking Schistosoma mansoni to colonic carcinoma occurrence. The aim of this study was to
The induction of tumour necrosis factor (TNF)-alpha from the monocytic cell line THP-1 by the streptococcal antigen I/II from Streptococcus mutans serotype f (protein I/IIf) was studied by use of recombinant polypeptides containing the discrete domains of the protein. The derivatives carrying the
To examine the possible implication of protein SR, an I/II-related antigen from Streptococcus mutans OMZ 175 (serotype f), in inflammatory reactions, we tested the immunomodulatory effects of protein SR on human monocytes. Using biotinylated protein, we provide evidence that protein SR binds to
Despite the importance of vectors in natural dissemination of plant viruses, relatively little is known about the molecular features of viruses and vectors that permit their interaction in nature. Cucumber necrosis virus (CNV) is a small spherical virus whose transmission in nature is facilitated by
OBJECTIVES
The present study aims to investigate the anti-oxidant and anti-inflammatory properties of seagrass
Halophila ovalis sulfated polysaccharide on HT-29 cell line.
SUBJECTS AND METHODS
Monosaccharides composition was identified using liquid
A fucose-containing, sulfated polysaccharide ascophyllan was isolated from the brown alga Ascophyllum nodosum. Composition analysis demonstrated that ascophyllan mainly contains uronic acid, xylose, fucose, and sulfate half ester in approximately equimolecular proportions, which are evidently
Tissue necrosis is a form of cell death common in advanced and aggressive solid tumors, and is associated with areas of intratumoral chronic ischemia. The histopathology of necrotic regions appear as a scaffold of cellular membrane remnants, reflective of the hypoxia and cell degradation events
The purpose of the present study is to treat lipopolysaccharide (LPS)-induced fulminant hepatitis by NF-κB decoy complex with fucose-appended dendrimer (generation 2; G2) conjugate with α-cyclodextrin (Fuc-S-α-CDE (G2)). Fuc-S-α-CDE (G2, average degree of substitution of fucose (DSF2))/NF-κB decoy
Although tumor necrosis factor (TNF) antagonists reduce many clinical features of inflammatory bowel disease, complete mucosal healing occurs in fewer than 50% of patients. The Fc-region of monoclonal antibodies against TNF has immunosuppressive properties via effects on macrophage polarization. We
Virions of infectious pancreatic necrosis virus (IPNV) were completely disintegrated upon dialysis against salt-free buffers. Direct visualization of such preparations by electron microscopy revealed 5.0- to 6.5-nm-thick entangled filaments. By using a specific colloidal gold immunolabeling
Treatment of U937 cells with fructose 1-phosphate (P) and fucoidan dose-dependently inhibited the adhesion of these monocytic cells to TNF alpha-stimulated human umbilical vein endothelial cells (HUVEC) (IC50 = 1 mM and 10 micrograms/ml respectively). These carbohydrates (CHO) failed to inhibit U937
Fucan is a term that defines a family of homo- and hetero-polysaccharides containing sulfated l-fucose in its structure. In this work, a heterofucan (F2.0v) from the seaweed, Dictyota menstrualis, was evaluated as an antinociceptive and anti-inflammatory agent. F2.0v (20.0 mg/kg) inhibits 100% of
Fucosylated glycans on pathogens are known to shape the immune response through their interaction with pattern recognition receptors, such as C-type lectin receptors (CLRs), on dendritic cells (DCs). Similar fucosylated structures are also commonly found in a variety of allergens, but their
Three heteroglycans, T1a, T1b, and T1c, have been isolated from the body of Tremella fuciformis Berk. They are composed of mannose (Man), xylose (Xyl), glucose (Glc), fucose (Fuc), and glucuronic acid (GlcA). According to methylation analysis and partial acidic hydrolysis the main chains of T1a,
