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.

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.

Uncover novel antimicrobials with prospective health benefits for sea turtles.

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…

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.…

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…

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…

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.

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?

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.

Influenza CD8(+) T-cell epitopes are conserved amongst influenza strains and can be recognized by influenza-specific cytotoxic T-cells (CTLs), which can rapidly clear infected cells. An influenza peptide vaccine that elicits these CTLs would therefore be an alternative to current influenza vaccines,…

New drugs for use as tuberculosis (TB) treatment are needed due to the constrains of classical antibiotics against TB and the rise of antibiotic-resistant strains, making TB a harder and harder disease to treat.

An overview of Quantitative Pharmacology projects

Researchers from Leiden University Medical Center (LUMC) have discovered how malaria parasites escape the immune system of mosquitoes. The so-called QC enzyme changes proteins on the outside of the malaria parasite such that the immune cells are unable to recognise the parasite. As a result, the parasite…

In this thesis, I study 1) metabolic alterations in tuberculosis related to wasting syndrome in human patients as well as in rodent and fish animal models. 2) effects of the mutation of the leptin gene on cachexia and diabetes in rodent and zebrafish animal models.

Leiden professor of Cellular Immunology of Parasitic Infections Maria Yazdanbakhsh receives the prestigious NWO Spinoza Prize this year. This, in many ways, border-crossing scientist contributes with her research to more effective vaccines against parasitic infections and better medication for inflammatory…

The infectious diseases malaria and tuberculosis are responsible for 2.1 million deaths every year. Leiden researchers are currently testing a new tuberculosis vaccine.

Bacteria caught red-handed, deeply frozen just as they were about to cause Lyme’s disease. Ariane Briegel is wildly enthusiastic about the wonders she observes thanks to three elements: a freezing technique, a camera-equipped microscope, and AI. ‘It’s fascinating. Every single cell is different.’

A COVID-19 vaccine that specifically instructs the immune system to produce T-cells rather than antibodies is shown to provide good protection in a mouse model, Leiden University Medical Center (LUMC) researchers report in Nature Communications. According to them, the alternative vaccine may offer a…

MHC class I and MHC class II molecules present peptides to the immune system to drive proper T cell responses. Pharmacological modulation of T-cell responses can offer treatment options for a range of immune-related diseases.

Studying the impact of urbanisation on the respiratory health of past Dutch populations (1200-1850 CE).

Living systems scale from unicellular microbes to complex multispecies communities that constantly change over time. Within the theme Development & Disease, we enhance our fundamental understanding of development and homeostasis of living cells and systems. We analyze the normal situation and how stresses…

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…

How do lipases in Mycobacterium tuberculosis help the bacteria survive, and can we target them to create new antibiotics?

What is the effectiveness of (booklet or online) self-help programmes for people with somatic stressors and depressive symptoms? What works best for whom? How to improve motivation and adherence?

Microbes influence and respond to other organisms. This theme explores the dynamic relationships within plant and animal microbiomes, and the immune responses that govern host defense. Using model systems such as zebrafish, insects, and plants, we investigate fundamental processes and engineer microbes…

Because of their large surface area and immunological competence, mucosal tissues are attractive administration and target sites for vaccination.

Fungal infections pose a significant threat to individuals with compromised immune systems and despite advancements in diagnosis and treatment, they continue to jeopardize patient’s health.

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

Seasonal influenza vaccines provide protection against matching influenza A virus (IAV) strains mainly through the induction of neutralizing serum IgG antibodies. However, these antibodies fail to confer a protective effect against mismatched IAV. This lack of efficacy against heterologous influenza…
