The applications of studying the early development of insects range from agriculture to material science.

Breast cancer is the most common cancer in women worldwide. Metastasis, the process by which cancer cells spread to other parts of the body, makes treatments less effective. It is important to unravel the mechanism of metastasis.

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

The investigations described in this thesis lay out strategies aimed at advancing antibiotic research and development. The examples presented revolve around two main approaches: understanding drug-target interactions and target identification.

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

Kinase inhibitors are key therapeutic agents, particularly in oncology, yet their clinical efficacy is often hampered by off-target effects and limited understanding of their cellular target profiles.

This thesis tackles the difficulty of predicting the liver’s clinical response to novel therapies, a challenge arising from interspecies differences and limitations of existing in vitro models.

The type-IV secretion system (T4SS) is a machinery able to transfer DNA and proteins between bacteria and in certain cases also to eukaryotic cells.

Lysosomal acid glucosylceramidase (GBA1) is a lysosomal enzyme that degrades glucolipids with its main substrate being glucosylceramide (GlcCer). Defects in the GBA1 gene lead to glycosphingolipidosis Gaucher disease (GD), in which the hydrolysis of GlcCer is impaired and therefore, it accumulates in…

The research described in this thesis focused on the use of bioorthogonal antigens to investigate immunological processes in antigen presenting cells. Bioorthogonal antigens are antigenic proteins produced through recombinant expression in a methionine auxotrophic E. coli strain.

The cannabinoid receptor type 2 (CB2R) is associated with several inflammatory diseases with an unmet medical need (e.g. Alzheimers, multiple sclerosis, reumatoid arthritis). Development of new chemical biology strategies to study this protein is essential to aid future development of drugs for these…

To improve treatment of breast cancer patients it is important to understand all stages of breast cancer from initiation to in situ disease and progression to invasive disease. In this thesis we use intraductal injections of patient derived tissue to model ductal carcinoma in situ and invasive breast…

Studies naar perceptuele besluitvorming presenteren dezelfde stimulus doorgaans herhaaldelijk tijdens een experimentele sessie, maar negeren de volgorde van deze observaties, waarbij wordt uitgegaan van een onrealistische stabiliteit van beslissingsstrategieën tijdens proeven. Maar zelfs ‘stabiel’,…

In het onderzoeksprogramma Drug Discovery & Safety zijn we geïnteresseerd in de werkzaamheid en veiligheid van nieuwe medicijnen en nieuwe manieren om deze aspecten te bepalen. Daarvoor combineren we geavanceerde imaging en high-throughput screening technieken met computationele aanpakken zoals chem-…

Nierfalen is een serieus probleem omdat nieren zichzelf niet kunnen regenereren na ernstige beschadiging. Een mogelijke oplossing bestaat uit het kunstmatig laten groeien van gezond nierweefsel. Daarvoor moeten wetenschappers eerst de ontwikkeling begrijpen tijdens de allereerste fase, in de foetus.…
