hexasaccharide/inflammation

The purpose of this study was to investigate the anti-arthritic effects of synthesized chondroitin sulfate E hexasaccharide (sCSE-6, CAS 866407-73-0), using a type II collagen-induced arthritis model in mice. sCSE-6 was administered subcutaneously on a daily basis to type II collagen

Astrosterioside A, a sulfated steroidal hexasaccharide isolated from starfish Astropecten monacanthus showing potent anti-inflammatory activity, was synthesized in a convergent linear sequence of 24 steps and in 6.8% overall yield from adrenosterone.

Acidic proteins were isolated from synovial fluid from two osteoarthritic and two rheumatoid arthritic patients and identified by MS. It was found that the most abundant protein in all of the samples was the mucin-like protein lubricin. Further characterization of lubricin from the different

BACKGROUND Previous studies showed that heparin's anti-allergic activity is molecular weight dependent and resides in oligosaccharide fractions of <2500 daltons. OBJECTIVE To investigate the structural sequence of heparin's anti-allergic domain, we used nitrous acid depolymerization of porcine

Glycosaminoglycans (GAGs) of the extracellular matrix (ECM) contribute to the regulation of physiological processes by binding various immune-competent proteins. Due to their large structural diversity, the analysis of the binding properties and their functional consequences is challenging. The

Selectins are a class of cell adhesion molecules that play a critical role during the initial steps of inflammation. The N-terminal domain of P-selectin glycoprotein ligand-1 (PSGL-1) binds to all selectins, but with the highest affinity to P-selectin. Recent evidence suggests that the blockade of

Hyaluronan is a ubiquitous glycosaminoglycan involved in embryonic development, inflammation and cancer. In mammals, three hyaluronan synthase isoenzymes (HAS1-3) inserted in the plasma membrane produce hyaluronan directly on cell surface. The mRNA level and enzymatic activity of HAS1 are lower than

Increasing interests have been focused on the functional roles of hyaluronan degradation products, namely hyaluronan oligosaccharides, as signal molecules regulating cell growth, differentiation, malignancy, and inflammatory responses. It is clear that molecular size of hyaluronan oligosaccharides

Lymphocyte infiltration is a hallmark of acute rejections in solid organ transplants, such as cardiac allograft. We have previously shown that lymphocyte extravasation to cardiac grafts undergoing rejection is largely due to interactions between lymphocyte L-selectin and its sialyl Lewis x (sLex)

Gelling sulfated polysaccharide from the cystocarpic plants of Ahnfeltiopsis flabelliformis was studied. According to FT-IR and NMR spectroscopy data, the polysaccharide was found to be iota/kappa-carrageenan with iota- and kappa-type units in a 2:1 ratio containing beta-carrageenan units and minor

Interactions of the chemokine CCL5 (RANTES) with glycosaminoglycans (GAGs) are crucial to the CCL5-mediated inflammation process. However, structural information on interactions between CCL5 and longer GAG fragments is lacking. In this study, the interactions between oligosaccharides derived from

The cytokine interleukin-10 (IL-10) is an important regulator of the host immune system with both pro- and anti-inflammatory functions. Glycosaminoglycans (GAGs) play a decisive role in the biology of many growth factors, e.g., for receptor binding or protection from proteolytic degradation. GAGs of

Heparan sulfate (HS) is a glycosaminoglycan present on the cell surface and in the extracellular matrix, which interacts with diverse signal molecules and is essential for many physiological processes including embryonic development, cell growth, inflammation, and blood coagulation. D-glucuronyl

Tumor necrosis factor-stimulated gene-6 (TSG-6) is a hyaluronan (HA)-binding protein that is essential for stabilizing and remodeling the extracellular matrix (ECM) during ovulation and inflammatory disease processes such as arthritis. The Link module, one of the domains of TSG-6, is responsible for

Although the interaction between interleukin-8 (IL-8) and glycosaminoglycans (GAGs) is crucial for the mediation of inflammatory effects, little is known about the site specificity of this interaction. Therefore, we studied complexes of IL-8 and heparin (HEP) as well as other GAGs in a
