This work describes the use of click-to-release chemistry to get spatiotemporal control over immunocytokine activity. Until now, immunocytokines (cytokines coupled to a tumor-targeting-moiety) remained active throughout the body, being able to bind their respective receptors, causing mild to severe…

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

The first steps are made in personalised cancer vaccination strategies, which aim to induce a more specific immune response with fewer side effects. The activation of cytotoxic T cells is crucial for an effective immune response.

Microscopic insight on lipid-based nanomedicine in vivo remains limited to the perception of the knowledge that could be obtained: if we interpret only what we see, then we only believe to know. Although believing to know encapsulates an undefined amount of uncertainty in the exploration of lipid-based…

This thesis advances our understanding of lipid uptake, a vital first step in lipid metabolism, by developing innovative click chemistry-based tools to study how immune cells internalize lipids.

Chronische pijn is een complex verschijnsel, met grote individuele verschillen in pijnbeleving en behandelrespons. Dit interdisciplinair onderzoek richt zich op de rol van zintuiglijke prikkelverwerkingsgevoeligheid bij volwassenen met chronische pijn, en de relatie daarvan met centrale sensitisatie,…

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.

Why do sexual violence policies still fail to systematically address men and masculinities, when the need for cultural change among men has been central in public debates since #MeToo?

Making sensitive data reusable through synthetic data generation

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…

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.

This thesis describes research aimed at discovering inhibitors selective for either of the two endoplasmic reticulum α-glucosidases, ER-I and ER-II, with the overarching goal of discovering new antiviral agents to treat viruses that rely on host N-glycosylation for proliferation.
