Anthropogenic change is reshaping ecological systems, raising concerns about increasing transmission of infectious diseases. Among these, mosquito-borne diseases may be particularly sensitive to environmental change, as their transmission depends on vector populations.

Neurodegenerative diseases pose a large medical and societal challenge. The etiology of these diseases is still poorly understood, which makes drug discovery for these diseases difficult.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

The lipids in the uppermost layer of the skin, the stratum corneum (SC), play an important role in the skin barrier function. The three main SC lipid classes are ceramides (CER), cholesterol and free fatty acids.

Atherosclerosis is the most prominent underlying pathology of cardiovascular disease and an important cause of major adverse cardiovascular events.

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

Endothelial dysfunction and microvascular diseases are key drivers of cardiovascular disease, the world's leading cause of death.

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…

Machine Learning is becoming a more and more substantial technology for industry.

Cardiovascular disease is the leading cause of death worldwide.

Advanced mass spectrometry of glycosphingolipids takes the central stage in this thesis. Investigations focus on characterization of glycosphingolipid metabolism in health and disease with emphasis to the detection and accurate quantitation of known and so far unknown glycosphingolipids and closely…

Solute carrier (SLC) transporters are a large and diverse class of relatively understudied transmembrane proteins.

Control of infectious diseases poses continuous challenges for human health.

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

This research project studies the distribution and impact of medieval malaria in the Netherlands.

The disease acute myeloid leukemia (AML) is characterized by fast progression and low survival rates.

Nanoparticles can be used as delivery systems for both small molecules and macromolecules such as proteins, peptides or oligonucleotides. This thesis focuses on the use of liposomes, nanometric vesicles formed by a lipid bilayer enclosing an aqueous core. Liposomes are highly versatile delivery syst…

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

Antibiotica, bacteriën en resistentie zijn zeer geschikte onderwerpen voor een profielwerkstuk. Hier vind je alvast een aantal handige links.

Leidse chemisch biologen, onder leiding van dr. Mario van der Stelt, hebben stoffen ontdekt die ontstekingsprocessen in de hersenen kunnen verminderen.
