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.

The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.

Why does the past elicit this intense activity in the present? What does the past mean for the present, and what does it do to it? A WAR OF WORDS will engage this complex of Chinese claims to Manchu-Korean ancient history, South Korean reactions, public discourse and cultural expression in both states,…

The single cell group (SCG) is part of the Metabolomics & Analytics Centre Our research is centered around developing innovating analytical methods tailored for small-volume, or single cell analysis to enable metabolomics-driven systems biology in personalized health strategies. We are always on…

Despite being the object of intense study, embryonic development has been difficult to model due to a number of reasons. First, complex tissues can be comprised of many cell types, of which we probably only know a subset.

Synthetic or artificial cells are vesicles, often lipid vesicles, with wide ranging applications from drug delivery to nanoreactors in biocatalysis. We are developing polymer-lipid hybrid vesicles for applications in compartmentalised biocatalysis, in which the polymer has been shown to greatly enhance…

In this thesis, we describe the potential of cell mechanical phenotyping for immune cell characterization, diagnosis, drug testing, as well as treatment of disease.

Atherosclerosis is the most prominent underlying pathology of cardiovascular disease and an important cause of major adverse cardiovascular events.

This book explores the lasting legacy of the controversial project by the Congress for Cultural Freedom, funded by the CIA, to promote Western culture and liberal values in the battle of ideas with global Communism during the Cold War.

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’.

Archives were a common target during the Second World War, and hundreds suffered damages. Among these archival losses, the losses to medieval manuscript collections stand out.

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

Despite the wealth of historical literature on the Second World War, the subject of religion and churches in occupied Europe has been undervalued.

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

Writing under Wartime Conditions is a study into North and South Korean literature written during the Korean War.

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

Volume I of The Cambridge History of Strategy offers a history of the practice of strategy from the beginning of recorded history, to the late eighteenth century, from all parts of the world.

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.

Japan's Occupation of Java in the Second World War draws upon written and oral Japanese, Indonesian, Dutch and English-language sources to narrate the Japanese occupation of Java as a transnational intersection between two complex Asian societies, placing this narrative in a larger wartime context of…

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

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.

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

The research within the Division of Cell Systems and Drug Safety, headed by Prof. Bob van de Water, is focused on novel therapeutic modalities and novel concepts in early drug discovery, in order to develop more effective and safer therapeutic strategies. We generate advanced cell and computational…

This project investigates the effects of the Asia-Pacific War (1931-1945) and the Korean War (1950-1953) on the production, distribution, preparation and consumption of food in transwar Japan and Korea.

Bas Rietjens and his colleagues researched the Russia-Ukraine war, exploring this multitude of facets and their interconnections.

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

Which brain cell does what, when Parkinson's disease arises? It won't be long before this jigsaw is solved piece by piece. Ahmed Mahfouz, computational biologist, combines bio-knowledge from Leiden with algorithms from Delft and is getting closer to finding the key.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

In this article, Jasmijn Boeken, explores in which ways the defining characteristics of the different zones can be found in the digital sphere.

Cell-based medicinal products (CBMPs), such as CAR T cells, are highly complex biopharmaceutical products offering various treatment options for serious illnesses such as cancer or autoimmune diseases.

In this article, Ben de Jong, research fellow at the Institute of Security and Global Affairs, examines the relationship between double agents and their handlers.

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…

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.

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.

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.

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…

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

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

From molecule, to cell, to organism. The high-level drug research at the Cell Observatory aimes at reducing the spread of cancer and developing new medicines for tuberculosis.

Mechanobiology is a major area in biology, however, mechanics is currently a missing element in drug development pipelines. This has led to a high cost for the society. Mechanotoxicity of drugs often appears as a long-term side effect of drugs, and has led to removal of drugs from the market. Furthermore,…
