hexasaccharide/과민반응

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

Several recent studies have demonstrated a relationship between the composition of the gut microbiota in infancy and subsequent development of allergic disease. Human milk is the major food in infancy and may thus profoundly influence the composition of the gut flora. Oligosaccharides in breast milk

OBJECTIVE To investigate the inhibitory effect of heparin-derived oligosaccharides (Oligs) on secretion of interleukin-4 (IL-4) and interleukin-5 (IL-5) from human peripheral blood T lymphocytes (PBTLs). METHODS Oligs were prepared by three different heparin depolymerization methods and separated by

Three kinds of chitooligosaccharides were prepared using traditional (ZCOS), microwave irradiation (WCOS), and enzymatic hydrolysis (YCOS), and their monomer compositions and in vitro and in vivo immunomodulatory activities were determined. ZCOS was mainly comprised of disaccharides and
