Research in this group, headed by Gerard van Westen, focusses on computational methods integrated in different parts of the drug discovery process. More specifically, topics include innovative treatments for cancer, selectivity modeling, translational research, allosteric modulation, drug resistance…

Microbes influence and respond to other organisms. This theme explores the dynamic relationships within plant and animal microbiomes, and the immune responses that govern host defense. Using model systems such as zebrafish, insects, and plants, we investigate fundamental processes and engineer microbes…

On this page you will find an overview of awards and prizes granted to our staff and students in 2026, as well as special appointments at Leiden University and other institutions.

The majority of scientists, from archaeologists through to zoologists, collect huge volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics, we can develop algorithms for analysing and identifying patterns…

Three fundamental research projects at Leiden in physics, chemistry and medical science have received funding from the Dutch Research Council (NWO). They involve research on magnetic fields in the universe, the role of myeloid cells in cancer immunotherapy and the evolution of ancient proteins.

Leiden scientists are the main applicants for five projects that have been awarded a Science Groot grant of up to 3 million euros in the Science Domain. In addition, several Leiden scientists are involved in other projects that have been awarded funding.

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…

Dendritic cells (DC) play a prominent role in the priming of CD8(+) T cells. Vaccination is a promising treatment to boost tumor-specific CD8(+) T cells which is crucially dependent on adequate delivery of the vaccine to DC.

The ambition of the Medical Systems Biophysics and Bioengineering group led by Alireza Mashaghi is to develop and use physics and engineering concepts and tools for pathophysiology, diagnostics and therapy.

This thesis explores different avenues to develop insurmountable antagonists for CC Chemokine Receptors, such as CCR1, CCR2 and CCR5.

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.

Monoacylglycerol lipase (MAGL) is the principal enzyme responsible for hydrolysis of the endocannabinoid 2-arachidonoylglycerol (2-AG). MAGL inhibition provides several potential therapeutic opportunities, including anti-nociceptive, anti-inflammatory and anti-cancer activity.

The CC chemokine receptor 2 (CCR2), a member of the G protein-coupled receptor (GPCR) superfamily, is widely involved in autoimmune and inflammatory diseases. However, no drugs for this receptor have made it to the pharmaceutical market yet.

Chemical-induced organ toxicity is a major concern in the development and use of chemicals, including drugs, pesticides, industrial chemicals and cosmetics. In the last decades, the onset and progression of chemical-induced organ toxicity has been linked amongst others to perturbation of mitochondri…

This thesis describes the synthesis and biological evaluation of TLR2/6, TLR4, TLR7/8 and TLR9 ligands, of which the activity can be conditionally controlled.

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

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.

One of the main challenges in the development of an effective anti-cancer vaccine is the generation of an adequate and directed cellular immune response.

The HOPES study is one of the largest investigations of this kind to date! By studying existing brain scans and data collected form over 4,000 14-25 year olds, the project team hopes to identify specific changes in the brain that make young people vulnerable to suicidal thoughts and behaviours.

The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

A monthly lecture series about early drug discovery research at Leiden University.

The mission in this division, headed by Laura Heitman, is to design and synthesize novel and better ligands for drug targets. Drug discovery is a lengthy but inspiring adventure. It is often an interplay between academic institutes and pharmaceutical industry, in which scientists at university develop…

Leiden University seeks to bring knowledge, academic top talents, and resources from Leiden and Latin America and the Caribbean together in mutually beneficial joint research projects that are content-driven, based on existing excellent research. Connecting research and researchers.

We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

Due to the modern techniques of combinatorial chemistry and high-throughput screening, data on the biological activity of many millions of compounds is known. However, it is still very difficult to transfer this data into knowledge: if we know that compounds A and B bind to a certain protein with high…

In the Drug Research theme, we primarily work with rodents. Rodents, such as mice, are one of the most common laboratory animals. These small mammals are easily housed and exhibit a rapid rate of reproduction.

This work describes the use of click-to-release chemistry to get spatiotemporal control over immunocytokine activity. Until now, immunocytokines (cytokines coupled to a tumor-targeting-moiety) remained active throughout the body, being able to bind their respective receptors, causing mild to severe…

An interdisciplinary team of Leiden researchers has discovered that wasting syndrome, a severe byproduct of tuberculosis, is the same for all humans and animals studied. The discovery offers new opportunities to investigate the still insufficiently understood condition. The scientists also developed…

With the rise of information and communication technologies, large amounts of data are being generated and stored in databases. In order to get a better grip on these large amounts of data, serious efforts are being made to discover patterns and relations in the data with the help of new techniques.…

e-SIDES (ethical and societal impact of data sciences) is a Coordination & Support Action (CSA) part of the Horizon 2020 programme.

What are the circadian disturbances underlying depression vulnerability? How are they related to mood, cognition and sleep ?

Embedding ethical legal and societal aspects for responsible military AI.

Examining mediation and moderation.

The precise psychobiological mechanisms leading to chronic physiological stress responses have not been sufficiently explained, although stress is a major risk factor for disease and early death. A problem for conventional stress theory is that most of these responses seem to occur in situations without…

The data-driven economy allows for the collection and processing of large amounts of data. Such data can be used to optimize profits by (dynamically) differentiating prices for different consumers.

Leiden University has awarded its prestigious University Medal to Emeritus Professor Lex van der Eb. As a pioneer in genetics and molecular biology, he received this honour for his services to science and his key role in the development of the Leiden Bio Science Park (LBSP).
