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.

More than 1.3 million people worldwide die of tuberculosis (TB) each year, making research on its prevention and control essential. Researchers from various disciplines in Leiden are studying TB. A symposium on 24 March will highlight different activities in the hope of boosting nationwide collabora…

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.

An overview of awards and prizes granted to our staff and students in 2022, as well as special appointments at Leiden University and other institutions.

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.

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

No less than four Leiden research teams have been awarded a grant by NWO. On 27 July NWO honoured 21 applications in the Open Competition ENW-XL. NWO awards the grants to consortia in the exact and natural sciences who are doing unconnected fundamental research that is 'driven by curiosity'.

This project focuses on two Mayan languages in contact: Awakateko and K’iche’. With the aim to create a database to be accessible to researchers, students, and indigenous activists interested in Mayan languages, this project will train Mayan speakers on transcription, translation, and analysis of…

The Department of Medical Microbiology at Leiden University Medical Center (LUMC) is researching antiviral drugs that could treat and prevent SARS-CoV-2 in various projects. One part of the PanCoroNed project is being led by Martijn van Hemert and involves lab tests into the antiviral effect of molecules…

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.

Publishing about your research is a key aspect of your career as a researcher; the majority of research publications are written in English. When applying for research funding, too, it is very important to ensure that your application is written in clear, accessible English. Maria Sherwood-Smith, Academic…

Un)timely Crises explores how ‘crisis’—as a narrative, concept, grammar, and experience—structures time and space. This collectively written volume extends Bakhtin’s ‘chronotope’ to challenge mobilizations of crisis within neoliberal governmentality. The book explores how contemporary crises can trigger…

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.

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.

Among Leiden’s Firsts was Hajjah Maria Ulfah Soebadio Sastrosatomo. In 1933, she was the first Indonesian woman student to earn a law degree.

Kazimierz Twardowski (1866-1938) is the founder of the Lvov-Warsaw School with its strong tradition in logic and its scientific approach to philosophy. Twardowski’s unique way of doing philosophy, his method, is of central importance for understanding his impact as a teacher.

This network brings together scholars whose work explores how contemporary frameworks of crisis produce experiences of the present, rehash or disrupt established narratives of the past, and broker specific outlooks on the future. We collaborate in studying these crisis-scapes and exploring how they…

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…

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.
