In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

Research truly comes to life when it contributes meaningfully to society. By sharing our findings, advising policymakers or contributing to community projects – we can make a real impact. Scroll down and discover how Science and society can mutually benefit from each other.

In eight chapters, the thesis of Rafaël Vos covers the effect of temperature and pressure on the electrochemical CO2 reduction.

Despite the fact that gold nanoparticles (GNPs) are one of the most studied nanoparticles, there is still a necessity for new approaches allowing for effective protective coating to enable wider use of GNPs in biomedical applications.

Leiden biophysicist Stefan Semrau was granted an NWO Vidi earlier this month. He will use the grant to study the role of electricity in embryonic development and tissue regeneration.

Engineering an efficient microbial enzymatic polyethylene degradation pathway via an innovative combination of biochemistry and computational biology tools for enzyme discovery and characterization.

Can politicians say whatever they want? What is the limit and when can the Public Prosecution Service act? PhD candidate Jip Stam examined the limits of free speech in criminal law. 'Intervening too soon can threaten democracy and the rule of law,' he warns.

Repairing organs, tissues and cells to fight chronic diseases.

The Cardiovascular Pharmacology research group headed by Ilze Bot aims to elucidate the mechanisms that underlie atherosclerotic plaque destabilization, which is the key process that leads to acute cardiovascular syndromes such as a myocardial infarction or stroke.

An overview of the research at the Cancer Dug Target Discovery group.

Methods of treatment for chronic illnesses are limited. Doctors and researchers at Leiden University Medical Center (LUMC) and Leiden University are working on new therapies as an alternative for organ transplants. The goal is to cure the illnesses by restoring organs to their original function. Stem…

In this research group, headed by Prof. Erik Danen, the aim is to unravel cellular signaling mechanisms in normal and diseased cells, with a long-standing interest in cell adhesion signaling. In complex multicellular organisms such as ourselves, a division of labor emerges where different tissues and…

In this research group, headed by Bob Van de Water, cell signaling programs that underlie adverse drug reactions as well as cancer development and progression are unraveled. Adverse drug reactions involve cell injury in critical target organ cells which leads to the activation of cellular stress response…

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…

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…

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…

Tuberculosis bacteria survive by hiding in our immune cells. In her PhD research, biologist Salomé Muñoz Sánchez explores how boosting the body’s own defenses might outsmart this deadly pathogen. Her work reveals two key proteins that help immune cells destroy the bacteria.

When the tokay gecko loses its tail, a new one grows from resident stem cells at the stump. Each tissue type - muscle, bone, blood vessels and skin - develops from specific stem cells. This discovery by Luthfi Nurhidayat holds potential implications for advancing regenerative medicine in humans. Nurhidayat…

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.

Researchers from Leiden University Medical Center (LUMC) and the Leiden-based biotech company Ncardia have joined forces to develop a new platform that enables the automated production of 3D cardiac microtissues. This platform will allow large numbers of drugs to be tested quickly

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.
