The emergence of complex diseases resulting from abnormal cell-cell signaling and the spread of infectious diseases caused by pathogens are significant threats to humanity. Unraveling the dynamic mechanisms underlying cell-cell signaling and infectious disease spreading is crucial for effective disease…

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

Cardiovascular disease is the number one cause of death worldwide. The most important risk factor for developing this disease is high cholesterol levels in the blood.

The Minor Computational Approaches to Disease, Signaling and Drug Targets (CADSDT) is focused on fundamental scientific research required for discovery of new drug targets and development of new drugs.

In this thesis, we describe the potential of cell mechanical phenotyping for immune cell characterization, diagnosis, drug testing, as well as treatment of disease.

In this thesis, two potential therapeutic targets for diabetic nephropathy were dentified and investigated. First, we show that glomerular clusterin is upregulated in diabetic nephropathy and demonstrated that recombinant clusterin protein can protect the podocytes against oxidative stress in vitro.…

The skin is our natural barrier and lipids are a key part of this barrier. In the outer skin layer, the stratum corneum (SC), lipids form a densely organized structure dependent on the composition of these lipids.

The research described in this thesis combines the latest insights in lysosomal function with lysosome centred cell signalling.

Psycholoog Bernadet Klaassens heeft een groot fMRI-onderzoek opgezet naar het effect van medicijnen op hersennetwerken bij veroudering en de ziekte van Alzheimer. Het leverde een unieke dataset op en zicht op een nieuwe methode om medicijnen te ontwikkelen voor patiënten met Alzheimer.

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

Naast het feit dat angstproblemen veelvoorkomend zijn en het daarom belangrijk is om hier effectieve preventieve programma’s en behandelingen voor te ontwikkelen, is dat in deze tijd extra relevant.

Atherosclerosis is a progressive disease resulting in the formation of an arterial plaque. Despite lipid lowering, recurrent cardiovascular events remain a risk. While atherosclerosis is primarily lipid-driven, the immune system plays a critical role in the pathophysiology.

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.

Cardiovascular syndromes are the major cause of death in Western societies.

Current therapies for patients with atherosclerosis are targeted primarily on reducing blood cholesterol, but this fails to prevent a large number of cardiovascular events.95 In order to identify new therapeutic strategies for treating atherosclerosis, it is important to study the interactions between…

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

Op 2 en 3 oktober 2017 heeft een delegatie van de Afdeling Jeugdrecht deelgenomen aan de 15e Europese regionale conferentie van de International Society for the Prevention of Child Abuse and Neglect in Den Haag.

Parkinson's disease is the second most common neurodegenerative disease in the world. One of its symptoms is the loss of dopaminergic neurons in the substantia nigra pars compacta.

Cardiovascular diseases are among the most frequent causes of death in the world. The main underlying pathology of cardiovascular diseases is the development of atherosclerosis in the medium and large-sized arteries.

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

The aim is to develop methods to assess environmental and occupational exposure to (individual) pesticides, to be applied in epidemiological studies investigating pesticide exposure and human health. Furthermore, we aim to investigate the potential association between exposure to pesticides and Parkinson’s…

Atherosclerosis is the main underlying pathology of cardiovascular disease. Atherosclerosis is caused by an immune response which is directed against (modified) lipoproteins which accumulate in the vessel wall.

According to the amyloid cascade hypothesis, accumulation of beta-amyloid (Aβ) peptides initiates the pathological cascade in Alzheimer's disease (AD).

The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

Childhood obesity is an increasing health issue. In the first part of this thesis comorbidities in children with obesity were studied, concerning the diagnostic process and dosing regimens.

Acute cardiovascular clinical events such as myocardial infarction and cerebral stroke represent the major cause of death in Western societies. These pathologies are primarily resulting from atherosclerosis, a progressive condition characterized by the accumulation of lipids, immune cells, and fibrous…

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society.
