De missie van het Plant Sciences onderzoeksprogramma is om bij te dragen aan de duurzame productie van gewassen van hoge kwaliteit, bloemen en hoogwaardige producten met een biologische basis. Dit wordt gerealiseerd door het opdoen van fundamentele kennis over biologische processen omtrent de ontwikkeling…

Design and synthesis of two 3-substituted swainsonine derivatives with the aim to improve the potency and selectivity towards Golgi alpha-mannosidase II.

The thesis describes the development, synthesis and biological evaluation of several proteasome inhibitor designs. Mainly, this work focusses on designing proteasome inhibitors that selectively inhibit the immunoproteasome, while leaving the constitutive proteasome mostly, if not completely, untouch…

The aim of the research described in this thesis was to use structure-based design to optimise multiple properties of aryl sulfoxide monoacylglycerol lipase inhibitors as anti-inflammatory analgesics.

Thesis focused on uncovering the underlying mechanisms of the lysosomal storage disorders Gaucher's disease using chemical tools, biochemical assays and lipidomics.

The chemical synthesis of inhibitors and probes targeting endo-glycosidases.

Synthetic methodlogy is described, aiding in the synthetic preparation of putative inhibitors of retaining and inverting glycosidases and glycosyl transferases. All constructs are cyclophellitol-based cyclitols.

This thesis describes the design and synthesis of novel small molecules based on sulfur-containing heterocycles for the inhibition of glycosidases and glycosyltransferases related to Fabry and Pompe disease.

This thesis describes the development of a variety of mannosylated conjugates. Antigen presenting cells bear mannoside recognizing receptors that actively transport antigen into the cell. This thesis exploits this feature for the development of improved vaccines.

The findings in this thesis improve the understanding of 1) the relationship between exposure characteristics and toxicity of ENPs, 2) the joint toxic action of ENP mixtures and the comparison to metal salt mixtures, 3) how NOM affects the individual and joint toxicity of ENPs, 4) the extent of trophic…

This Thesis describes the synthesis of D-alanylated ribitol-based wall teichoic acids from S. aureus to probe their interaction with immune-binding partners.

Within this thesis the central stage is taken by the discovery and investigation of transglycosylation of sterols. First, investigation focuses on the development of a method to accurately detect and quantify glucosylated metabolites in biological materials.

Viral diseases constitute one of the major challenges in modern medicine. Membrane-targeting have broad-spectrum potential and could distinguish viral membranes from the host cell plasma membrane by the difference in membrane curvature.

In the last decades, activity-based protein profiling (ABPP) has emerged as a powerful chemical tool that may aid the ever-challenging drug discovery process.

Microglia support the central and peripheral nervous system by forming the first line of defense against hazardous events. Microglia are increasingly acknowledged as critical players in neurodegenerative diseases, highlighting them as potential therapeutic targets.

How can we bridge the gap between experts and the general public?

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

De traditionele scheiding van leeuwen in een Afrikaanse en een Aziatische ondersoort is onterecht, zegt bioloog Laura Bertola. In Afrika leven twee ondersoorten. Promotie 18 maart.

Fate and toxicity of copper nanoparticles was related to the water chemistry of the environment and pristine size.

The work described in this Thesis is focused on the assembly of oligosaccharide fragments derived from a fungal polysaccharide, galactosaminogalactan (GAG) and fragments of the exopolysaccharide Pel, generated by Pseudomonas aeruginosa.

Nicotinamide adenine dinucleotide (NAD+) is the substrate used for the introduction of the ubiquitous and highly dynamic PTM in which either one or multiple adenosine diphosphate ribose (ADPr) moieties are covalently attached to a nucleophilic side chain of an specific amino acid in the target protein…
