title: Norwalk virus-like particles bind specifically to A, H and difucosylated Lewis but not to B histo-blood group active glycosphingolipids.
abstract: Noroviruses and norovirus virus-like particles (VLPs) exhibit strain specific patterns in their binding to ABH and Lewis histo-blood group antigens. In this study we demonstrate for the first time specific binding of Norwalk virus VLPs to type 1 and type 2 chain glycosphingolipids (GSLs) carrying ABH and Lewis antigens. N-succinimidyl-3-tributylstannyl benzoate (ATE) was precursor labeled with (125)I and then conjugated to VLPs. The (125)I-VLPs were used in GSL thin-layer chromatogram binding assays and displayed binding to H type 1, Lewis b, A type 1, A Lewis b GSLs but no binding to B type 1 or B Lewis b GSLs. For the type 2 chain GSLs the Norwalk VLPs bound to H type 2, Lewis y, A type 2 and A Lewis y. In addition, the VLPs bound to several complex GSLs from blood group O and A, but not from blood group B red blood cells.
