Abstract:

Endogenous biological processes including cellular recognition, motility and differentiation together with infection often result from carbohydrate-based interactions. Investigation into glycobiological interactions using sugar-coated nanoparticles are the basis for the research described herein. Metallic nanoparticles were coated with a variety of thiol-based linker molecules. Heterobifunctional PEG (carboxyl/thiol) molecules were found to be most successful in preventing non-specific aggregation. The carboxylic acid functionality of the PEG molecules used allowed for subsequent coupling of a

Abstract:

Saccharides act important roles in many biological processes as recognition molecules, signalling molecules and adhesion molecules. However, due to the complexity and diversity of oligosaccharides the direct synthetic approaches cannot fully meet the demands for all of the pure and well-defined oligosaccharides being studied in glycobiology. The efficient synthesis of glycomimetics, glycopolymers, offers an attractive route to solve this problem. Thus, the synthesis and application of glycopolymers of various architectures has been extensively investigated. Meanwhile, In order to explore the m

Abstract:

The complement system is a fundamental component of innate immunity that orchestrates complex immunological and inflammatory processes. Complement comprises over 30 proteins that eliminates invading microorganisms while maintaining host cell integrity. Protein-carbohydrate interactions play critical roles in both the activation and regulation of complement. Mannose binding lectin (MBL) activates the lectin pathway of complement via the recognition of sugar arrays on pathogenic surfaces. X-ray scattering and AUC combined with constrained modelling were used to identify a bent structure for the

Abstract:

This dissertation focuses on the synthesis and characterization of glyconanomaterials, as well as their applications in studying carbohydrate-protein interactions. A new and versatile method for coupling underivatized carbohydrates to nanomaterials including gold and silica nanoparticles was developed via the photochemically induced coupling reaction of perfluorophenylazide (PFPA). A wide range of carbohydrates including mono-, oligo- and poly-saccharides were conjugated to the nanoparticles with high yields and efficiency. New analytical methods were developed to determine the binding affinit

Abstract:

Les interactions sucre-lectine jouent un rôle très important dans de nombreux processus biologiques comme les infections par des virus ou des bactéries. Toutefois, ces interactions étant faibles, la présentation de manière multivalente des résidus saccharidiques est nécessaire pour obtenir une augmentation significative des constantes d'association. Une technique basée sur l'utilisation de glycooligonucléotides et d'une puce à ADN utilisée comme plateforme d'ancrage a permis d'étudier l'affinité d'un grand nombre de composés envers les lectines PA-IL et PA-IIL de Pseudomonas aeruginosa et la l

Abstract:

Carbohydrate-binding proteins of non-immunological origin -lectins- have been recognized over the last decades as decisive players in numerous biological processes, ranging from cellcell communication, fertilization, pathogen-cell adhesion to metastasis. Consequently, there is an increasing interest in finding powerful and nanosized tools to screen for these molecules and to study their carbohydrate interactions in detail. Here, two complementary approaches are described to characterize lectin-carbohydrate interactions with high sensitivity, low sample consumption, and without the need for sam

Abstract:

Carbohydrate-protein interactions are responsible for several biological functions. While these interactions maintain high levels of specificities, the binding strength of individual carbohydrate-protein recognitions are weak, with dissociation constants (Kd) ~10-3-10-6 M. In order to increase the binding strengths meaningful to physiological functions, multivalent, clustered patches of carbohydrate ligands are required. Synthetic glycoclusters contribute in a significant manner to understand the fine details of the weak carbohydrate-protein interactions. The extent of clustering of the ligand

In the case of the MGL, the KD of MGL/LacdiNAc complex is at low µM range (5.3 µM) and similar that obtain for the MGL/α-Me-GalNAc complex, whi

Abstract:

Siglecs are a family of cell surface lectins majorly expressed in immune cells, which through the recognition of sialic acids, present at the terminals of glycans in glycolipids and glycoproteins, modulate immune responses. Hypersialylation is a common phenomenon in cancer cells, which exploits aberrant interactions between cancer-associated sialoglycans and siglecs (namely Siglec-7, -9 and -15) in a strategy to dampen the anti-tumour immune activity. Therefore, understanding the molecular details of the recognition of cancer-associated sialoglycans by siglecs is essential for the development
