The Cleveringa chair was installed by Leiden University in memory of Professor Rudolph Pabus Cleveringa and the courage he demonstrated in November 1940 during the German occupation . It also commemorates the liberation of the Netherlands in 1945.

BACKGROUND: Explant human skin equivalents (Ex-HSEs) can be generated by placing a 4mm skin biopsy onto a dermal equivalent. The keratinocytes migrate from the biopsy onto the dermal equivalent, differentiate and form the epidermis of 1(st) generation Ex-HSEs. This is especially suitable for the expansion…

The outermost layer of the skin, the stratum corneum (SC), is responsible for the skin barrier function, protecting the body from pathogens, chemicals and other unwanted substances from the external environment. The SC lipid matrix provides the only continuous pathway through the SC and is considered…

Moritz Jesse has been awarded a Jean Monnet Chair by the European Commission. In his MIND-EU Project he will focus on a coherent way to teach Migration, Integration, and Non-Discrimination at Leiden Law School at bachelor and master level.

On the occasion of prof Paul van der Heijden’s stepping down as Rector Magnificus and President of the Executive Board of Leiden University in 2013 the Chair bearing his name on Social Justice was established. It was a “farewell present” of the Leiden University to it’s Rector.

This UNESCO Chair at CWTS aims to contribute to UNESCO’s agenda to foster diversity and inclusion in science. The chair has two main lines of work:

Karwan Fatah-Black, a historian at Leiden University’s Faculty of Humanities and senior researcher at the KITLV/Royal Netherlands Institute of Southeast Asian and Caribbean Studies, has been appointed as the UNESCO Chair holder in Comparative History of Slavery and the Transition to Citizenship.

The Chair Democratic Representation in the Kingdom focuses on the political relations between the ‘European’ Netherlands and the six Caribbean islands in the Kingdom; so-called Kingdom Relations. Professor Wouter Veenendaal investigates the quality of democratic representation in the Kingdom, both within…

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

From 1 August 2018, Alanna O'Malley was appointed as Chair of United Nations Studies in Peace and Justice, focusing on the ‘lesser-known actors’ of the UN: women, the youth, the agents of informal diplomatic networks within the UN and actors from the Global South. This Special Chair has been created…

In the studies described in this study, we introduce a novel ex vivo human skin barrier repair model. To develop this, we removed the upper layer of the skin, the stratum corneum (SC) by a reproducible cyanoacrylate stripping technique.

People with relatively high levels of lipids in their blood are less likely to develop allergic conditions such as eczema and asthma. These lipids cause genes that play a key role in allergic reactions to be less active. Researchers from the Leiden University Medical Center (LUMC) have published an…

Anionic particles play an important role in biological systems where they fulfil many essential functions for cells.

The research described in this thesis shows that hypercholesterolemia, a well-established risk factor for atherosclerosis, can impact skin lipid pool and barrier function already at young age. In the field of atherosclerosis, we showed that the small peptide Lyp-1 can be used as a targeting molecule…

Nanodiscs are small, disc-shaped structures designed to mimic biological cell membranes, composed of a lipid bilayer stabilized by scaffold proteins. Membrane proteins play crucial roles in essential processes such as nutrient and waste transport, molecular recognition, and cell signalling, making them…

A memorable farewell symposium and a royal distinction: Professor Joke Bouwstra could not have completed her career at Leiden with more pleasure. On Friday, 14 June, she received a Royal Honor from Leiden Mayor Peter van der Velden, who appointed Bouwstra as a Knight in the Order of the Dutch Lion for…

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.

The universities of Tokyo and Leiden are installing a rotating chair named after Professor Hisashi Owada. The Owada chair will focus on interaction between international law and international relations through interdisciplinary approaches. Dominique Moïsi, a professor at King’s College in London, will…

On 24 May 2022, the universities of Tokyo and Leiden organized a rotating chair named after Professor Hisashi Owada. The Owada Chair focused on the interaction between international law and international relations in an interdisciplinary perspective. Dominique Moïsi, a professor at Kings College London…

The Kikkoman chair is a new chair in Leiden sponsored by the Kikkoman Foundation and the Association of Friends of Asiatic Art. The chair will address the intercultural dynamics of Asia and Europe.

Focus in skin research

For the first time researchers have succeeded in placing a layer of graphene on top of a stable fatty lipid monolayer. Surrounded by a protective shell of lipids, graphene could enter the body and function as a versatile sensor. The results are the first step towards such a shell, and have been published…

Heart failure is a major health care problem with high mortality.

The PID-directed shift in PIN polarity has been broadly accepted as one of the essential mechanisms for the regulation of auxin transport polarity.

Preterm birth is a major contributor to neonatal morbidity and mortality and is associated with both acute complications and long-term health consequences.

Dominique Moïsi, a professor at King’s College London, will be the first holder of the Owada chair. ‘In the present international context of polarisation and divisions within societies and amongst nations, any effort at bringing Asia and Europe closer to each other is truly important.’

Freya Baetens, Professor of European Law, has been awarded a Chair by the Francqui Foundation in Belgium for the impact of her work on lawmaking and policymaking in Europe and beyond.

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

The Skin Barrier and Vaccination group is led by Prof. Joke Bouwstra. One of the key functions of the skin is its barrier function, which is located in the uppermost layer of the skin, the stratum corneum. The stratum corneum consists of enucleated dead cells (corneocytes) embedded in a lipid matrix.…

Atopic eczema is a skin disease with increasing incidence currently affecting 25% of the paediatric population. In atopic eczema the skin barrier function is reduced. This barrier is formed by the outermost layer of the skin called the stratum corneum (SC). The SC consists of terminally differentiated…

Political scientist Karolina Pomorska (Institute of Political Science, Leiden University) has been awarded a Jean Monnet Chair. The aim of her chair, entitled The EU and the World, is to promote and strengthen teaching and research in European Studies in Leiden and in The Hague.
