    Abstract: Aluminum coated glass slides provide a novel glycan array platform. Specifically, aluminum coated glass slides increase sensitivity of fluorescent based assay methods. Additionally, aluminum coated glass slides allows for mass spectroscopic analysis of carbohydrates and provide a platform for examining activity of cellulases. The unique properties of ACG slides include: the metal oxide layer on the surface can be activated for grafting organic compounds such as modified oligosaccharides; the surface remains electrically conductive, and the grafted oligosaccharides can be simultaneously characterized by mass spectrometry and carbohydrate-binding assay; and the slides are more sensitive than transparent glass slides in binding analysis.

    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: The present disclosure relates to a novel class of anti-HER2 monoclonal antibodies comprising a homogeneous population of anti-HER2 IgG molecules having the same N-glycan on each of Fc. The antibodies of the invention can be produced from anti-HER2 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: 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 provides a glycoengineered SARS-CoV-2 spike protein which is capable of eliciting an enhanced immune response relative to a native spike protein of SARS-CoV-2 and its variants. The glycoengineered spike protein exposes the glycosylation sites and at the same time preserves the tertiary structure of the spike protein. The present disclosure therefore provides improved immunogens, vaccines, and methods for better prevention and treatment of the emerging coronavirus infections.
