A combined computational-experimental approach to define the structural origin of antibody recognition of sialyl-Tn, a tumor-associated carbohydrate antigen. [PDF]

open access: yes, 2018
Anti-carbohydrate monoclonal antibodies (mAbs) hold great promise as cancer therapeutics and diagnostics. However, their specificity can be mixed, and detailed characterization is problematic, because antibody-glycan complexes are challenging to ...

Histochemical localization of sialic acids and antimicrobial substances in eccrine glands of porcine snout skin

open access: yesEuropean Journal of Histochemistry, 2012
The distribution of sialic acids and antimicrobial products (lysozyme, IgA, lactoferrin, β-defensin 2) as well as Rab3D in the eccrine glands of porcine snout skin was studied by sialoglycoconjugate histochemistry and immunohistochemistry.

Identification of Potential Binding Sites of Sialic Acids on the RBD Domain of SARS-CoV-2 Spike Protein

open access: yesFrontiers in Chemistry, 2021
COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is still an emergent pandemic for humans. The virus infection is achieved by penetrating its spike protein to host cells via binding with ACE2.

Sialic Acid Mimetics to Target the Sialic Acid–Siglec Axis

open access: yesTrends in Biochemical Sciences, 2016
Sialic acid sugars are vital regulators of the immune system through binding to immunosuppressive sialic acid-binding immunoglobulin-like lectin (Siglec) receptors on immune cells. Aberrant sialic acid-Siglec interactions are associated with an increasing number of pathologies including infection, autoimmunity, and cancer.

Enzymatic Synthesis of Trideuterated Sialosides

open access: yesMolecules, 2019
Sialic acids are a family of acidic monosaccharides often found on the termini of cell surface proteins or lipid glycoconjugates of higher animals. Herein we describe the enzymatic synthesis of the two isotopically labeled sialic acid derivatives d3-X ...

Synthesis of partially O-acetylated N-acetylneuraminic acid using regioselective silyl exchange technology. [PDF]

open access: yes, 2014
Postglycosylation acetylation of sialic acid imparts unique roles to sialoglycoconjugates in mammalian immune response making structural and functional understanding of these analogues important.

Spatiotemporal expression patterns of sialoglycoconjugates during nephron morphogenesis and their regional and cell type-specific distribution in adult rat kidney [PDF]

open access: yes, 2018
The expression of α2,6- and α2,3-linked sialic acids on N-glycans was studied in embryonic, postnatal, and adult rat kidney. Histochemistry and blotting using Polyporus squamosus and Sambucus nigra lectins for α2,6-linked sialic acids and the Maackia ...

Expanding the Reaction Space of Linkage-Specific Sialic Acid Derivatization

open access: yesMolecules, 2019
The human glycome is characterized by a high degree of sialylation, affecting, amongst others, cell−cell interactions and protein half-life. An established method for the linkage isomer-specific characterization of N-glycan sialylation is based on ...

Gut bacteria responding to dietary change encode sialidases that exhibit preference for red meat-associated carbohydrates. [PDF]

open access: yes, 2019
Dietary habits have been associated with alterations of the human gut resident microorganisms contributing to obesity, diabetes and cancer1. In Western diets, red meat is a frequently eaten food2, but long-term consumption has been associated with ...
