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.

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.

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.

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.

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

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.

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

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

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?

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…

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.

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.

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.

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,…

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…

The Translational Immuno-Pharmacology group works on translating the efficacy of anti-infective therapy from preclinical (e.g. in vivo) to clinical, and is led by Rob van Wijk. Infectious diseases, such as tuberculosis, are in constant need of new therapies that work better, faster, and with less risk…

Uncover novel antimicrobials with prospective health benefits for sea turtles.

Macromolecular Biochemistry is a section of the Leiden Institute of Chemistry at Leiden University, comprising the PIs Marcellus Ubbink, Remus Dame, Lars Jeuken, Anne Wentink, Sebastian Geibel, Anjali Pandit, René Olsthoorn, Alia, and Steffen Brünle.

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…

Parasitic worms and stomach bacteria suppress immune reactions such as allergic responses. Parasitologist Hermelijn Smits and lung specialist Christian Taube from the LUMC are trying to learn from these micro-organisms.

The Quantitative Pharmacology group headed by Coen van Hasselt focusses on the application of state-of-the-art quantitative pharmacometrics and systems pharmacology modeling combined with translational experimental models to develop personalized treatment strategies for antibiotics and to combat antimicrobial…

How do plants lure microscopically small 'support teams' into their roots for protection against diseases? And what functions are activated in the microbes and the plants?

Supervisor: P.J.J. Hooykaas

Aspergillus niger is an important industrial producer of organic acids and enzymes producing large amounts of spent fungal biomass.

People who have taken antibiotics in the past three months pay more attention to negative facial expressions, according to research by postdoc Katerina Johnson and assistant professor Laura Steenbergen. This may explain how antibiotics increase the risk of developing depression.

Antibiotic resistance, caused by widespread use of antibiotics, leads to bacterial infections that are difficult, if not impossible, to treat and is a major worldwide health concern.

The focus of the Antiviral Pharmacology group led by Anne-Grete Märtson is optimizing antiviral therapy for different viral infections by conducting clinical trials and using innovative computational and dynamic laboratory methodologies.

The special issue on “Quo Vadis, Pragmatics?” is the result of a lively discussion among members of the editorial board of the Journal of Pragmatics triggered by the most recent revision of the journal's scope statement. The 11 contributions that make up this special issue cover a rich suite of themes,…

Originating from a collaboration between Leiden University, the Leiden University Medical Center, and the Technical University of Munich in 2021, the Virtual ChemBioTalks are an annual, half-day virtual event with world-leading speakers from all sub-disciplines of Chemical Biology.
