    • Core 1 β3-galactosyl transferase specific molecular chaperones (Cosmc-1) and nucleic acids encoding the core 1 β3-galactosyl transferase specific molecular chaperones or proteins having core 1 β3-galactosyl transferase specific molecular chaperone activity are described. The polynucleotides encoding Cosmc-1 can be used to transform or transfect host cells for producing substantially pure forms of active forms of core 1 β3-galactosyl transferase and/or for use in an expression system for post-translational core 1 glycosylation of proteins or peptides produced within the expression system, for example, glycosylation via a β3-linkage, of an N-acetylgalactosamine linked to a serine, threonine or other linking amino acid on peptides or proteins requiring O-, N-, or S-linked glycosylation.

    • Species of schistosoma , such as schistosoma mansoni, S. japonicum and S. haematobium, which infect humans and animals, synthesize the Lewisx (Lex), lacdiNAc (LDN) and fucosylated LDN (LDNF) carbohydrate antigens. Parasitic helminths other than schistosomes, such as Dirofilaria immitis (responsible for heartworm), Fasciola hepatica (a liver fluke) and Haemonchus contortus (intestinal fluke) also synthesize the LDN and LDNF antigens, but they do not synthesize, or synthesize only undetectable amounts of, Lex antigen. The differential detection and abundance of the Lex, LDN and LDNF antigens in sera and other bodily fluids of individuals is diagnostic of the presence of active and/or previous infections from schistosomes and other parasitic helminths. The present invention is directed to methods of differential detection and diagnosis of parasitic helminth infections, and kits for use in such methods.

    • Tyrosine sulfate on PSGL-1, particularly at least one of residues 46, 48 and 51, functions in conjunction with sialylated and fucosylated glycans, most preferably Thr-57, to mediate high affinity binding to P-selectin. PSGL-1 O-glycans have been determined to consist of disialylated or neutral forms of the core-2 tetrasaccharide Gal.beta.1.fwdarw.4GlcNAc.beta.1.fwdarw.6(Gal.beta.1.fwdarw.3)GalNAcOH. A minority of the O-glycans are .alpha.1,3 fucosylated that occur as two major species containing the sialyl Lewis x antigen--one species is a disialylated monofucosylated glycan: Fuc.alpha.1 .dwnarw. 3 NeuAc.alpha.2.fwdarw.3Gal.beta.1.fwdarw.4GlcNAc.beta.1 .dwnarw. 6 NeuAc.alpha.2.fwdarw.3Gal.beta.1.fwdarw.3GalNAc-R, and the other is a monosialylated, trifucosylated glycan having a polylactosamine backbone: Fuc.alpha.l .dwnarw. 3 NeuAc.alpha.2.fwdarw.3Gal.beta.1.fwdarw.4GlcNAc.beta.1.fwdarw.3Gal.beta.1.fwdarw.

The O-glycans defined herewith can be used to inhibit inflammation mediated by P-selectin.
