“Temminck’s Order” is the scientific biography of Coenraad Jacob Temminck (1778–1850), a Dutch naturalist and the first director of ’s Rijks Museum van Natuurlijke Historie in Leiden.

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

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.

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.

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.

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.

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

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.

Over de hele wereld staan koraalriffen onder druk. Zarinah Waheed onderzocht de riffen in Maleisië en komt tot de conclusie dat de bescherming van koraalriffen beter kan. Promotie op 22 november.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

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.

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