Despite recent advances in medicine, many devastating disorders like cancer and cardiovascular, neurodegenerative and infectious diseases still lack effective treatments. In order to address this challenge, we, as scientists from Leiden University, joined hands in the LED3 network. LED3, for Leiden…

LIACS organizes different lectures and seminars like the LCN2 Seminars and SAILS Lunch Time-seminars.

There are many complex links in the chain that provides patients with new drugs: from fundamental science, to clinical tests, to production. The entire chain can be found in Leiden. Leiden University, the Leiden University Medical Center (LUMC) and the businesses at the Leiden Bio Science Park (LBSP)…

This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

We investigate bacteria and fungi to understand their malicious or beneficial impact on food crops and their pathogenic or antibiotic role in human health.

Improving healthcare with our scientific discoveries: that is the goal of pharmaceutical research at Leiden University. And there’s a lot involved in that. Our research starts with the discovery of the effect achieved by a particular substance, and sometimes continues all the way through to the development…

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.

Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology. We are part of the Faculty of Science at Leiden University.

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 LED3 hub, consisting of researchers from the Leiden Institute of Chemistry (LIC), the Institute of Biology Leiden (IBL), the Leiden Academic Centre for Drug Research (LACDR) and the Leiden Institute of Advanced Computer Science (LIACS), is very excited to organize the “LED3 Lectures”. This lecture…

Control of infectious diseases poses continuous challenges for human health.

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

The effective treatment of tuberculosis (TB) remains a major challenge to global health.

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

Research in the Lars Jeuken group focusses on redox-active proteins and membranes enzymes, aiming to understand bacterial respiration at the molecular level for the development of antimicrobials and semi-artificial photo-synthetic cells.

Pseudomonas Aeruginosa is a Gram-negative bacterium which can form biofilms, increasing its resistance against antibiotics and the host immune system. Polysaccharides are an integral part of this biofilm, one of these polysaccharides is called Psl. PslG is a glycosidase, able to cleave this polysaccharide,…

How do mycobacteria subvert the defenses of host immune cells?

Actinobacteria are well known for the production of bioactive natural products, many of which have applications in the fields of human, animal and plant health. Subject of this thesis are the anthracyclines, glycosylated aromatic polyketides with potent anticancer activity.

Are you graduating at the Faculty of Science? Or are you supervising a PhD student? At the Graduate School of Science you find support at every phase of your PhD.

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

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.

Though tuberculosis can be cured today, new resistant strains of the bacteria are becoming a growing problem in the medical world. Biologist Annemarie Meijer and her colleagues are studying resistance to this disease. Their research is already yielding several interesting clues that could help the development…

A vaccine based on sugar coats does have the potential to combat a multi-resistant staphylococcus. That is what Jeroen Codée and his colleagues from Utrecht state in Nature. In doing so, they are contradicting the earlier conclusions of German colleagues.

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…
