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…

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

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.

Cardiovascular disease is the leading cause of death worldwide.

In order to be able to develop effective medicine and treatments to prevent or cure autoimmune diseases or cancer we need to understand the mechanisms how they arise and what drives their course.Unravelling the fundamental molecular mechanisms influencing the onset and course of diseases such as allergies,…

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…

Schistosomiasis is an acute and chronic disease caused by blood dwelling parasitic trematodes of the genus Schistosoma, and it is classified as the second most socioeconomically devastating parasitic disease, second only to malaria.

Control of infectious diseases poses continuous challenges for human health.

Sphingolipids are important membrane compounds with a variety of functions. In mammalian cells, different enzymes are involved in the metabolism of sphingolipids, but interruption of this metabolism process leads to different diseases.

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

Hoogleraar Annemarie Meijer en dr. Sander Wezenberg ontvingen op 24 januari een NWO-subsidie voor hun onderzoek. De subsidie is toegekend binnen het Open Competitie ENW-M-programma en is bedoeld voor vernieuwende onderzoeksgebieden die de basis kunnen zijn voor onderzoeksthema’s van de toekomst.

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…

In vitro disease models play a fundamental role in drug research. They enable the systemic identification and validation of disease mechanisms and the discovery of possible drug targets. However, more than often, drug candidates that are identified in vitro fail in the later clinical stages of drug…

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.

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.

Waarom zijn mycobacteriën zulke succesvolle ziekteverwekkers? En zijn er verdedigingsmechanismen in het lichaam die helpen een infectie iets te verminderen? Om dit te achterhalen, heeft Annemarie Meijer de NWO Open competitie ENW-XL-beurs toegekend gekregen. Ze gaat niet alleen aan de slag. Aan het…

Leidse wiskundig biologen hebben een model ontwikkeld dat helpt verklaren hoe onder meer de ruggengraat en de wervels ontstaan in de embryonale ontwikkeling. Hetzelfde proces, maar dan andersom, speelt een sleutelrol bij de uitzaaiing van kanker. Publicatie in iScience.

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).

Onderzoekers moeten in een gespecialiseerde omgeving werken zodra ze aan de slag gaan met gevaarlijke bacteriën en virussen. Alleen in laboratoria met een hoog bio-veiligheidsniveau mogen ze deze microben bestuderen. Helaas zijn dure microscopen nodig om de microben goed te bekijken, maar is dat soms…

The zebrafish is a promising vertebrate model organism in early drug discovery and development.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

Lipid signaling is an essential biological event/process in a plethora of pathophysiological conditions. The underlying idea of this thesis is that many of the roles and the complex interplay of the individual signaling lipids in inflammatory processes and related conditions in health and disease is…

Glycosidases are important enzymes in the turnover of polysaccharides and glycoconjugates, and are involved in a range of human pathologies including genetic disorders such as Gaucher and Pompe disease, but also in various cancers.

Cardiovascular disease is a major global burden and atherosclerosis is the main underlying pathological process.
