The Indonesia Endowment Fund for Education (Lembaga Pengelola Dana Pendidikan or LPDP) has officially released the list of international universities and study programs for 2026, eligible to receive scholarship funding. The list serves as a guide for prospective applicants in determining their study…

We use zebrafish as a model organism to study human development and disease as well as animal welfare and environmental impact.

Projects within the theme ‘Computational Biology’ aim to employ mathematical or computational dynamical modelling approaches to discover novel concepts that are important for drug development.

Deficiency of glucocerebrosidase (GBA) underlies Gaucher disease, a common lysosomal storage disorder. Carriership for Gaucher disease has recently been identified as major risk for parkinsonism. Presently, no method exists to visualize active GBA molecules in situ. We here report the design, synthesis…

In autoimmune diseases such as rheumatism and diabetes the immune system attacks autologous proteins. Leiden researchers are trying to discover how this comes about.

Death in all types of melanomas is generally caused by metastasis. Uveal melanoma (UM) is the most common intraocular melanoma, there are currently no (patient-derived) animal models that faithfully recapitulate metastatic dissemination of UM.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

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

Our Division has created and maintains the Visualisation Core Facilities of the LACDR. This is a multi-user facility offering basic and advanced microscopic techniques to scientists of the LACDR.

In this project, we aim to develop mathematical models to mechanistically and quantitatively predict the dynamics of cellular stress pathway activation and its relation with toxic effects when cells are exposed to various toxicants.

Human and animal cells are very complex: very different chemical processes are going on at the same time, but they are separated from each other because the cells are divided in compartments. These compartments may also have a profound effect on the potential efficacy of therapeutics, because the drug…

Drug development critically depends on preclinical models that mimic human physiology, yet traditional two-dimensional cultures and animal models often lack predictive power.

This is a facility where research groups or small companies can apply for space if they need to culture human or animal cells.

Immune system defends our body against pathogens and cancerous cells, but excessive immunity can in turn lead to tissue damages and diseases. For example, scratching the surface of the eye ignites an immune response that aims at preventing infection but can also lead to edema, angiogenesis and eventually…

As of April 1, 2018, Erik Danen has been appointed as Professor of Cancer drug target discovery at the Leiden Academic Centre for Drug Research (LACDR). His discipline is cell biology of cancer, in which he focuses on the mechanisms underlying metastasis and therapy resistance.

Physics and Engineering Approaches to Biomedicine and Pharmacology

Intrigued by the way cells autonomously regulate their fate, we strive to understand and visualize cellular processes as the basis of Cell Signaling.

Dr. Foks obtained this fellowship for the project “Can promotion of efferocytosis induce regression of atherosclerosis?”, in which she aims to identify novel targets to promote regression of atherosclerosis. This research grant allows her to initiate independent research for the next three years.

Chemotherapy that does nothing until you irradiate it with light. Sylvestre Bonnet receives a Vici grant of 1.5 million euros for the development of this treatment. The Leiden chemist wants to build a new molecule to fight tumours that are at the time still difficult to treat.

More and more medicines are becoming available that target a tumour’s specific traits. The use of chemotherapy is continually undergoing improvement.

In the hunt for a vaccine against cervical cancer, fundamental knowledge about the immune system and organic chemistry have been brought together and have already resulted in a vaccine that is now being tested in clinical trials. Scientists are now working hard on an improved variant.

Atherosclerosis (thickening of the artery wall) is the most common cause of heart attacks or strokes, and one of the most common causes of death in the western world. People with this condition have to take medicine all their lives, so a vaccine for atherosclerosis would be a breakthrough.

Bacteria caught red-handed, deeply frozen just as they were about to cause Lyme’s disease. Ariane Briegel is wildly enthusiastic about the wonders she observes thanks to three elements: a freezing technique, a camera-equipped microscope, and AI. ‘It’s fascinating. Every single cell is different.’

Beautiful microscopic specimens play the leading role in the course 'Biodiversity Plant' for first-year Biology students. Normally these are put back in storage right after the course. But not this year!

This thesis investigates how cell shape and collective behavior influence the dynamics and structure of biological tissues, which are crucial for understanding processes like embryonic development, tissue regeneration, and metastasis.

In previous studies at our laboratory it was demonstrated that drug exposure of HepG2 cells can lead to an altered TNFα-induced NF-κB oscillatory phenotype, concurrent with a synergistically increased sensitivity for TNFα-induced apoptosis.

Research in the Lars Jeuken group focusses on redox-active proteins and membranes enzymes, aiming to understand bacterial respiration at the molecular level for the development of antimicrobials and semi-artificial photo-synthetic cells.

Activity-based protein profiling (ABPP) is a functional proteomics technique for directly monitoring the expression of active enzymes in cell extracts and living cells. The technique relies on irreversible inhibitors equipped with reactive groups (warheads) that covalently attach to the active site…

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.

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

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.

Atherosclerosis is a chronic inflammatory disease affecting millions of people world-wide.

In the research programme Drug Discovery & Safety, we are interested in the efficacy and safety of new drugs and novel means to decipher these aspects. Hence, we employ advanced imaging and high-throughput screening techniques next to computational approaches such as chem- and bioinformatics.

In this research group, led by Dr. Joost Beltman, the aim is to employ mathematical and computational dynamical modelling approaches in order to quantitatively and mechanistically understand the dynamical behaviour and regulation of intracellular networks of genes, proteins and metabolites as well as…
