title: Marine-derived polysaccharides for regulation of allergic responses.
abstract: Polysaccharides are macromolecules made up of many monosaccharides joined together by glycosidic bonds. Polysaccharides from marine sources are widely distributed as the principle component in cell wall structures of seaweeds or exoskeletons of crustaceans. So far, marine polysaccharides have been used in many fields of biomaterials, food, cosmetic, and pharmacology. Especially, numerous pharmaceutical properties of marine polysaccharides have been revealed such as antioxidant, anti-inflammatory, antiallergic, antitumor, antiobesity, antidiabetes, anticoagulant, antiviral, immunomodulatory, cardioprotective, antihepatopathy, antiuropathy, and antirenalpathy activities. Recently, several marine polysaccharides such alginate, porphyran, fucoidan, and chitin and its derivatives have been found as modulators of allergic responses due to enhancing innate immune system, altering Th1/Th2 balance, inhibiting IgE production, and suppressing mast cell degranulation. This contribution, therefore, focuses specially on the immunomodulatory effect of marine polysaccharides and emphasizes their potential application as candidates of pharmaceuticals as well as nutraceuticals to prevent allergic disorders.
