The word ¨pyroptosis¨ can be understood as ¨fiery falling¨, which describes the bursting of pro-inflammatory signals from the dying cell. Our observations indicate that pyroptosis also ¨spreads like wildfire¨ and once a cell dies via pyroptotic cell death, neighbouring cells are more prone to die as…

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

Cardiovascular syndromes are the major cause of death in Western societies.

The Death of Archaeological Theory, edited by John Bintliff and Mark Pearce, addresses the provocative subject of whether it is time to discount the burden of somewhat dogmatic theory and ideology that has built up over the last 25 years.

Atherosclerosis, in particular rupture of atherosclerotic plaques, is the underlying cause of most heart attacks or strokes and is the leading cause of death worldwide.

At the Cell Observatory we visualize the dynamic structures of life - from molecule to cell to organism -with the ultimate goal to tackle disease, for instance to reduce the spread of cancer and develop new medicines for tuberculosis. The development of new medicines is one of the core efforts of Leiden…

Can we exploit the cell death machinery of the host to develop new host-directed anti-TB treatments?

Decision support tool for cell therapy commercialization and business development

Leiden has a long history in the treatment of blood cell cancer. Research to find better therapies never stands still. One of the potential treatments currently being worked on is a ‘living medicine’.

Living cells on topographically-controlled substrates: Understanding Cell Motility in a Quasi-3D Environment

Mechanical interactions between cells and their environment play an important role in many biological processes.

BioSolar Cells is a five-year research project in which ten knowledge institutions and 45 private industries work together.

The master's specialisation From Cells to Organisms at Leiden University examines the molecular mechanisms underlying health and disease and how cells and organisms adapt to environmental factors.

What distinguishes a tumour cell from a healthy cell? Researchers are trying to answer this question as precisely as possible. Certain differences could eventually lead to new therapies.

In this project innovative technology for photovoltaics cells is developed and analysis of ecological and health related risks are explicitly accounted for.

Cardiovascular disease is a major global burden and atherosclerosis is the main underlying pathological process.

The CMCB brings together microbial cell biology expertise in Leiden. It aims at optimal resonance between the groups and maximal exploitation of the available infrastructure and to develop innovative cross-boundary technology platforms.

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

The loss of T-cell homeostasis and tolerance towards self-antigens is the underlying cause of autoimmune and inflammatory diseases like atherosclerosis, rheumatoid arthritis or type I diabetes. Traditionally, the treatment of these diseases consisted on systemic immune suppression, which can entail…

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

Cell adhesion signaling

Using mathematics to unravel biological processes: mathematician Lisanne Rens built a mathematical model to study the mechanisms that drive tissue shaping. Her model bridges different biological scales, from molecules to cells to entire tissues. ‘It’s fascinating how cells, that behave as individual…

Atherosclerosis is the main underlying pathology of cardiovascular disease. Atherosclerosis is caused by an immune response which is directed against (modified) lipoproteins which accumulate in the vessel wall.

We aim to engineer streptomycetes to fully exploit their potential for natural product productions, by a rational design and evolution approach.

Political scientists Rebekah Tromble and Michael Meffert (Leiden University) address the question why certain frames persist over time in the media while others fade away and still others disappear very quickly. They suggest an approach based in event-history methodologies for assessing the causes of…

Treatment with special stem cells seems to be a good option for suppressing the immune system in organ transplants. Researchers are trying to learn from processes that take place in the human body during pregnancy.

This functional genomics project aims at understanding the biology of the underlying mycelium differentiation and autolysis processes in much more detail.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

Bacteria have the ability to alter their morphology in order to adapt to changing environments.

Traditional drug discovery approaches have been hampered by (in vitro) cell-culture models that poorly represent the situation in the human body.

Stem cells can be differentiated into insulin-producing cells.

We aim to unravel the molecular mechanisms involved in the transformation of eukaryotic cells by Agrobacterium.

A very large part of intravenously administered nanoparticles are cleared through the liver. Within the liver, most nanoparticles are thought to be sequestered by macrophages (Kupffer cells). To achieve effective cell-specific targeting of drugs and non-viral gene delivery vectors, improved mechanistic…
