Living systems scale from unicellular microbes to complex multispecies communities that constantly change over time. Within the theme Development & Disease, we enhance our fundamental understanding of development and homeostasis of living cells and systems. We analyze the normal situation and how stresses…

We aim to gain a better understanding of the natural disease progression of ALS in order to improve clinical trial design and analysis and to support drug discovery and clinical development of new drugs.

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,…

This minor is focused on fundamental scientific research required for discovery of new drug targets and development of new drugs. Students learn how disease and drug-induced alterations in signaling pathways can be used for the discovery of new drug targets and the development of personalized drugs.

Bone research provides plenty of detailed data about the health of a person or a group. This data is not only used to reconstruct the past but also to fight disease today.

Having a chronic somatic condition can result in a variety of impairments in patients’ daily lives, including not only physical complaints such as pain, itch, and fatigue, but also problems of negative mood and impairments in social relationships. Next to disease characteristics, individual difference…

Which plant leaf characteristics are involved in thrips resistance in tomato?

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.

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

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.

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

LUMC researchers are looking for factors that point to illness at an early stage.

LUMC researchers are looking for factors that point to illness at an early stage.

Gaucher disease is a rare metabolic disorder, in which a mutation of the enzyme glucocerebrosidase (GBA1) causes buildup of its substrate glucosylceramide and the deacylated counterpart glucosylsphingosine in lysosomes.

This thesis describes biochemical investigations of glucocerebrosidase (GBA), the lysosomal β- glucosidase that is deficient in Gaucher disease (GD).

Multiple Sclerosis, Parkinson’s and Alzheimer’s disease are the most common neurodegenerative disorders. Unfortunately, no effective treatments are currently available to halt the progression of these neuroinflammatory diseases [1].

This minor focuses on the relationships between behaviour, health and illness.

We aim to provide new insights relating to the spectacular multi-cellular life cycle of streptomycetes and other actinobacteria.

How can we develop new chemical biology tools and approaches to understand and interfere with glucosylceramide metabolism in relation to Gaucher disease?

A new research line is the development of liquid biopsy fingerprints to predict early Alzheimer’s disease (AD) stage in human in readily accessible body fluids in human (in collaboration with: Dr. Geert-Jan Groeneveld, CHDR; Prof. Elga de Vries, Free University Medical Center; and others).

PhD student Wen Yang discovered how certain cell receptors in E. coli bacteria signal 'smells'. With the use of ice-cold electron microscopy microbiologists from Leiden gain more insight into how bacteria respond to their environment. Publication in mBio.

Biophysicist Alireza Mashaghi and his collaborators are taking up the fight against muscular dystrophy: genetic disorders that cause muscle weakness. They want to inhibit the clumping of proteins that results in toxic aggregates. For this, the team receives 550,000 euros from Health Holland. The team…

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

Mathematical biologists from Leiden have developed a model that helps to explain how the spine and vertebrae, among other things, form during embryonic development. The same process, the other way around, plays a key role in cancer metastasis. Publication in iScience.
