Atherosclerosis is a chronic inflammatory disease, and vaccination may be an attractive method to induce long lasting protection against endogenous factors that contribute to the development of atherosclerosis. We have shown that for example vaccination against modified LDL or interleukin-12 limits…

We focus on a better understanding of the mechanisms of cancer drug resistance and metastasis.

New technology offers many new possibilities for research, such as on dementia. ‘Organ-on-a-chip’ is a new technology in which small bits of organ are grown out of stem cells on a small plastic plate. A small piece of blood vessel, heart or nerve offers many new possibilities for research, such as…

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

Pancreatic ductal adenocarcinoma (PDAC) is the deadliest common cancer, with only 8% of patients surviving for five years. One reason for this poor outcome is that current chemotherapy treatments are highly toxic, often leaving patients too sick to receive treatment or forcing doctors to lower the dose…

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.

The Immune Activation and Tolerance group is headed by Dr. Bram Slütter. Vaccination is an experimental, but promising, treatment strategy for atherosclerosis. Previous work has shown that immunization of mice with modified LDL particles can reduce atherosclerotic lesion development, however such vaccines…

In this project, we aim to obtain a quantitative understanding of the role of the immune system in tumor regression, of the role of tumor cell heterogeneity in cancer growth and of tumor cell migration properties.

Our immune system protects us against disease, but every now and then, something goes wrong: an enemy invades our bodies or our immune system attacks our own cells and we become ill. Doctors and researchers at the Leiden University Medical Center (LUMC) want to be able to manipulate the immune system…

One-size-fits-all digital gamification sometimes hinders students’ learning due to the ignorance of individual differences. This project aims to explore how tailored digital gamification can be used in higher education and its effects on university students’ motivation and learning outcomes.

In this thesis, we will utilize embryonic zebrafish tumour models to understand the interaction between engrafted human cancer cells and macrophages from the host, test drug administration modalities and anti-cancer efficacies of newly-developed PDT and PACT compounds, and test a light-triggered liposomal…

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

The applications of studying the early development of insects range from agriculture to material science.

Proteases degrade matrix molecules in the atherosclerotic plaque, thereby reducing atherosclerotic plaque stability. Mast cells, that contain proteases such as tryptase and chymase, have been identified at the site of rupture in specimens of human coronary arteries and their number in the plaque was…

Integrins play an essential role in multicellular life by connecting cells to the extracellular matrix.

Microbial Sciences'contribution to the Development & Disease research theme is to perform world-class research to understand cellular morphogenesis, growth, development and virulence of microbes.

With cancer, a person’s body cells grow uncontrollably. Putting together a detailed picture of how this comes about makes it possible to develop efficient therapies. Researchers at the Leiden University Medical Centre (LUMC) and Leiden University are working together to gain a better understanding…

There are about 35,000 students with chronic illnesses in the Netherlands. If they cannot receive education in the classroom, they may be able to do so from home or a hospital with hybrid education. The question in this study is: how can interaction with the teacher and fellow students be promoted?

We investigate the molecular basis underlying health and disease and provide answers to existing and emerging health problems. Within this theme, we study diseases ranging from rare genetic disorders to cancer and infectious diseases. We make use of a wide variety of model systems and pursue diverse…

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.

Regeneration is the ability of an organism to restore damaged or lost tissue with a functional replacement, and without scarring. Many lizards can regenerate their tails.

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.

Bram van Dijk works on his PhD within the Media Technology research group. He teaches within a course on Social Technologies in the Media Technology program. Read what he has to say about the program.

What are the biological effects of Chinese herbal medicine in regulation of cancer cell metastasis?

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.

In 2020, Leiden University launched its stimulated interdisciplinary programs, including one focused on regenerative medicine.

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

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.

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