It is often said that the true character of a person is only revealed in a crisis. In these days, the coronavirus causes concern about the true state of the multilateral system. Political scientist Gisela Hirschmann (Leiden University) is worried about the future of multilateralism.

In online games conflicts between players may arise. Novin, Bos, Stevenson and Rieffe investigated factors that may explain why some adolescents react more angrily than others in this type of situation. In their realistically designed gaming environment, the (pre-programmed) fellow player suddenly started…

In this article Wouter Jong and Andrea Bartolucci explore the integration of scenario-based learning (SBL) into a crisis communication course to enhance students' practical skills and reflection in real-world contexts.

Inactivating mutations in BRCA1 or BRCA2 genes predispose to several types of cancer.

Which genes are involved in woodiness and associated traits such as drought tolerance, flowering time, stem elongation, life span, and plant herbivory, and how do these gene regulatory pathways overlap?

In the face of threats from other groups, humans, chimpanzees, and a selection of other species get closer with their own. This research shows that even bonobos show a moderated version of this effect. This suggests that this behavior may emerged prior to the Pan-Homo split, several millions years ago.…

Atherosclerosis (thickening of the artery wall) is the most common cause of heart attacks or strokes, and one of the most common causes of death in the western world. People with this condition have to take medicine all their lives, so a vaccine for atherosclerosis would be a breakthrough.

Key publications of the Aging and Immunity group

At least twice a year the Skandapurāṇa team meets to discuss drafts of the forthcoming volume of the critical edition. in March 2016 a five-day meeting was held at Kyoto University, where we discussed several chapters that will be part of Volume IV.

Tuberculosis causes 1.5 million deaths yearly and anti-tuberculosis therapies are threatened by emergence of drug resistance. Development of innovative drug combinations should be accelerated with the use of translational pharmacological models. Moreover, host-directed therapies (HDT), which stimulate…

In het Leids Universitair Medisch Centrum wordt gewerkt aan de ontwikkeling van een nieuw malariavaccin dat effectiever is dan de huidige vaccins.

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.

Mouse models are commonly used to assess the immunogenicity of therapeutic proteins and to investigate the immunological processes leading to antidrug antibodies. The aim of this work was to develop a transgenic (TG) Balb/c mouse model for evaluating the immunogenicity of recombinant human insulin (insulin)…

The division of BioTherapeutics consists of the former divisions Biopharmaceutics and Drug Delivery Technology.

Immunotherapies for cancer are an emerging class of therapeutic strategies which aim to treat cancer via augmentation of the immune system.

The current hepatitis B vaccines need to be stored and transported under refrigerated conditions (2-8 degrees C). This dependence on a cold-chain is highly challenging in areas where hepatitis B virus infections are endemic.

Lipid nanoparticles (LNPs) have enabled the success of mRNA vaccines but remain limited in broader therapeutic use by challenges in delivery efficiency, targeting, and mechanistic understanding.

The Chemical Biology & Immunology (CBI) group is headed by Prof. Sander van Kasteren and Prof. Kim Bonger.

Throughout the world fundamental labour rights in supply chains are being violated. Since the Rana Plaza disaster in Bangladesh shook the world, we can no longer turn our heads away.

Bacteria in the teeth tell us a lot about nutrition and disease in our ancestors. It also tells us more about the immune system. This provides clues for treating modern diseases and allergies. For a long time archaeologists were irritated by tartar on the teeth of excavated skulls. They thought that…

The team 'git merge -s octopus solution cup' has won the programming competition 'Northwestern Europe Regional Contest' on November 17. For the first time in 20 years, a team from Leiden has won this contest. On top of that, it is the second victory for the team in a month.

Unethical conduct by traders at banks is likely to be a continual problem as long as fraud cases are treated as the fault of a single rotten apple. Improving the team atmosphere reduces the likelihood of improper behaviour. This is the finding of psychologist Wieke Scholten from Leiden University in…

On 14 May 2021, Melanie Fink spoke at the conference ‘EU Responsibility in the International System: Setting the agenda’, organised by the University of Thessaloniki

On Monday 13 September, the Food Citizens? team and the Religious Matters In an Entangled World team from Utrecht University met in Leiden University’s historic 12th century building, Gravensteen.

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…

On Saturday 28 September we will be running again, for scholars at risk during the Leiden Science Run. Already 56 teams have registered, from Leiden and The Hague students to scientists and companies. There are still spots left for more teams!

The Municipality of Dronten is temporarily bailing out the Central Agency for the Reception of Asylum Seekers (COA) in Ter Apel by accommodating 360 asylum seekers at the Biddinghuizen event site in the province of Flevoland. This helps the COA avoid a sky-high fine. Rowie Stolk, Assistant Professor…

Epithelial cells play a crucial role in the lungs. PhD student Ying Wang researched the effects of cigarette smoke and viruses such as COVID-19 on these epithelial cells. ‘We hope to reduce the risk of pandemics in the future.’

Undesirable associations with sex can be unlearned, but return if the circumstances change. They must therefore be unlearned in different situations. The drug D-cycloserine may help here. These are the findings of psychologist Mirte Brom.

A group of 18 Leiden students and alumni are advising the University on diversity and inclusiveness. Portraits of 11 members of the Diversity Policy Feedback Group.

New or improved treatments for chronic and acute illness.

Cardiovascular diseases are still a major concern for the global health.

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.
