    Abstract: The present invention provides for an immunogenic composition comprising (a) a glycan, such as Globo H, stage-specific embryonic antigen-3 (SSEA-3) or SSEA-4, conjugated to a carrier protein through a linker; (b) an adjuvant comprising a glycolipid, such as a-galactosyl-ceramide adjuvant, wherein the composition induces an immune response, such as a higher relative level of IgG isotype antibodies compared to IgM isotype antibodies, or neutralising antibodies against at least one antigen selected from the group consisting of Globo H, Gb4, SSEA-3, and SSEA-4. Uses of the immunogenic composition for treating or inhibiting tumour growth are also provided.

    Abstract: Glycosphingolipids (GSLs) bearing α-glucose (α-Glc) that preferentially stimulate human invariant NKT (iNKT) cells are provided. GSLs with α-glucose (α-Glc) that exhibit stronger induction in humans (but weaker in mice) of cytokines and chemokines and expansion and/or activation of immune cells than those with α-galactose (α-Gal) are disclosed. GSLs bearing α-glucose (α-Glc) and derivatives of α-Glc with F at the 4 and/or 6 positions are provided. Methods for iNKT-independent induction of chemokines by the GSL with α-Glc and derivatives thereof are disclosed. Methods for immune stimulation in humans using GSLs with α-Glc and derivatives thereof are provided.

    Abstract: Immunogenic compositions comprising partially glycosylated viral glycoproteins for use as vaccines against viruses are provided. Vaccines formulated using mono-, di-, or tri-glycosylated viral surface glycoproteins and polypeptides provide potent and broad protection against viruses, even across strains. Pharmaceutical compositions comprising monoglycosylated hemagglutinin polypeptides and vaccines generated therefrom and methods of their use for prophylaxis or treatment of viral infections are disclosed. Methods and compositions are disclosed for influenza virus HA, NA and M2, RSV proteins F, G and SH, Dengue virus glycoproteins M or E, hepatitis C virus glycoprotein E1 or E2 and HIV glycoproteins gp120 and gp41.

    Abstract: The present disclosure relates to a novel class of anti-CD20 monoclonal antibodies comprising a homogeneous population of anti-CD20 IgG molecules having the same N-glycan on each of Fc. The antibodies of the invention can be produced from anti-CD20 monoclonal antibodies by Fc glycoengineering. Importantly, the antibodies of the invention have improved therapeutic values with increased ADCC activity and increased Fc receptor binding affinity compared to the corresponding monoclonal antibodies that have not been glycoengineered.

    Abstract: A novel UDP-Gal regeneration process and its combined use with a galactosyltransferease to add galactose to a suitable acceptor substrate. Also described herein are synthetic methods for generating Globo-series oligosaccharides in large scale, wherein the methods may involve the combination of a glycosyltransferase reaction and a nucleotide sugar regeneration process.
