abstract：:Mannan-binding protein (MBP), a Ca2+-dependent mammalian lectin specific for mannose and N-acetylglucosamine, is an important serum component associated with innate immunity. MBP activates complement and functions as a direct opsonin on binding to mannooligosaccharide-bearing pathogens. We have found that MBP recogniz...
