IL-13 is a Th2-derived pleiotropic cytokine that recently was shown to be a key mediator of allergic asthma. IL-13 mediates its effects via a complex receptor system, which includes the IL-4R alpha-chain, IL-4Ralpha, and at least two other cell surface proteins, IL-13Ralpha1 and IL-13Ralpha2, which specifically bind IL-13. IL-13 has been reported to have(More)
The degradation of xylan requires the action of glycanases and esterases which hydrolyse, in a synergistic fashion, the main chain and the different substituents which decorate its structure. Among the xylanolytic enzymes acting on side-chains are the α-glucuronidases (AguA) (E.C. which release methyl glucuronic acid residues. These are the least(More)
An α-l-arabinofuranosidase (ABF3) from Penicillium purpurogenum was purified and its possible biotechnological application in the enhancement of wine flavour combined with P. purpurogenum β-glucosidase was studied. A must from Muscat of Alexandria was used to isolate the glycosides. The total monosaccharide (glucose, arabinose and xylose) levels in the(More)
