How is inflammation in tuberculosis controlled by interplay between autophagy and inflammasome signalling?

The research described in this Thesis was aimed at designing and synthesizing nature-inspired compounds as part of TB vaccine discovery.

This project investigates how people choose linguistic forms like questions or statements in everyday speech.

Glucocorticoids (GCs) are widely prescribed as anti-inflammatory drugs due to their well-established immunosuppressive effects.

When a baby is born too soon, every minute counts – and so does every decision. To reduce uncertainty in those critical moments, biopharmaceutical scientist Manchu Umarani Thangavelu dedicated her PhD to identifying molecular markers of preterm birth and neonatal infection.

This special issue explores social meaning from the perspective of current theories in pragmatics.

Can small molecule drugs restore the immune system’s ability to fight tuberculosis by boosting autophagy?

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.

Control of infectious diseases poses continuous challenges for human health.

Researchers at Leiden University Medical Center (LUMC) and Radboud university medical center have been given the green light to deliberately infect volunteers with malaria in order to test a highly promising vaccine on them.

How can we enhance inspiration in metric modal improvisation and subsequently, in modal composition?

An overview of new research project: Politeness in Arabic Papyrus Letters

Sociopragmatics is a rapidly growing field and this is the first ever handbook dedicated to this exciting area of study.

These are our lecturers (in alphabetical order) for the 2026 Summer School in Languages and Linguistics.

The current resurgence of whooping cough is alarming, and improved pertussis vaccines are thought to offer a solution. Outer membrane vesicle vaccines (omvPV) are potential vaccine candidates, but omvPV-induced humoral responses have not yet been characterized in detail.

Leiden University and Leiden University Medical Center have joined the Netherlands Centre for One Health (NCOH), further strengthening the academic network in which such problems as antimicrobial resistance are studied.

Research at the Macromolecular Biochemistry group is comprised of the following research themes:

This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

Health workers have always sought ways to fight disease in vulnerable groups in the population. It is now clear that such research also benefits more prosperous countries. African worm infections and innovative thermometers have shown Leiden researchers how to fight diseases of affluence and keep health…

How can efficient chemical synthesis and clinical microbiology be combined to identify new antibiotics against Clostridioides difficile infections?

Tuberculosis is a major global health problem caused by the Mycobacterium tuberculosis complex, claiming more than a million lives annually.

Professor of Ultrastructural Biology Ariane Briegel has received a grant in the NWO Open Competition Domain Science in the XS category. This grant emphatically encourages curiosity-driven and bold research with a maximum of 50,000 euros.

In STAYAHEAD data-intensive approaches are being developed to ”decode the human immunome” with a focus on a global vaccine strategy. They have developed a rapid mass spectrometric test to analyse in real-time large numbers of variants of SARS-CoV-2 and the host immune response, and use these data to…

Researchers from the Netherlands Cancer Institute, the Leiden University Medical Center (LUMC) and Oncode have created a tracking system that can reveal how often cells have divided. This allowed them to find a yet undiscovered population of immune cells: young memory cells that behave like stem cells.…

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

The Examination Board of the Honours Academy determines whether the student meets the requirements of the relevant honours programme and handles requests for exceptions.

A research into how people eat and drink during their daily routines, and the circumstances under which these activities take place.

The Royal Netherlands Academy of Arts and Sciences (KNAW) has elected 16 new members, including two academics from Leiden: internist-infectiologist Meta Roestenberg and Arabist Petra Sijpesteijn.

By drawing on the personal experiences of contributors based in different institutions and countries, the articles in this special issue provide a fairly broad overview of ethics practices and concerns in different localities (though not globally, as we had originally hoped), showing, as one student…

When combined and used by specific people located in time and place, words can express something more than, different from, or even the opposite of their dictionary meanings.

Semantics and pragmatics are united in the study of linguistic meaning.

How do social and political developments influence the process of meaning-making in different parts of the world? Why is a particular discourse interpreted in numerous ways depending on the context it is produced and propagated? And how are culture, politics, history, and language intertwined?

From corpus pragmatics and metapragmatics to accountability and intentions, and from conversational structure and im/politeness to the role of emotions in utterance interpretation, the short articles collected here represent not just the wide scope of Michael's own work but also a snapshot of the field,…

This research cluster centres on regional, national, and global intersections between a variety of artistic and cultural expressions and their role in society from 1800 onwards.

Antimicrobial resistance (AMR) is the phenomenon that pathogens become insensitive to the antibiotics that we use against them. A growing number of pathogens is becoming resistant, with methicillin-resistant S. aureus (MRSA) as the most famous example. But while the threat of AMR represents a slow-moving…
