To improve treatment of breast cancer patients it is important to understand all stages of breast cancer from initiation to in situ disease and progression to invasive disease. In this thesis we use intraductal injections of patient derived tissue to model ductal carcinoma in situ and invasive breast…

The use-wear analysis of domestic implements provided new insights of the Single Grave Culture population in the Netherlands.

The chain that supplies patients with new medicines consists of various complex links: from fundamental research to clinical tests and production. This entire chain is represented in Leiden. Leiden University, the Leiden University Medical Center (LUMC), and the companies on the Leiden Bio Science Park…

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.

Providing each cancer patient with the right treatment remains a challenge. Oncode Accelerator aims to change this by innovating the way we develop cancer treatments, thus ensuring the patient is at the heart of the process. Leiden University, the LUMC and other partners will implement this new way…

This thesis focuses on the role of chemokine receptors CXCR3 and CCR2 in the inflammatory process and infection control using the zebrafish model.

Studies of perceptual decision-making typically present the same stimulus repeatedly over the course of an experimental session but ignore the order of these observations, assuming unrealistic stability of decision strategies over trials. However, even ‘stable,’ ‘steady-state,’ or ‘expert’ decision-making…

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

Sphingolipids are important membrane compounds with a variety of functions. In mammalian cells, different enzymes are involved in the metabolism of sphingolipids, but interruption of this metabolism process leads to different diseases.

Ecotox is a stimulating top-facility that provides an integrative research environment around the topic of ecotoxicological testing and experimental research. Research focus: Dose-response modelling Mode-of-actions and mechanism-of-actions Test method development, in view of targets in AOPs (adverse…

Gold nanorods are biocompatible nanoparticles that present an excellent two-photon signal that can be used to get high spatial resolution inside living cells. Gold nanorods are photostable and therefore can be followed inside cells for long time, with possible applications as trackers in live cells.

This thesis presents the first synthetic peptides ADP-ribosylated on serine, threonine, tyrosine, arginine and cysteine.

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.

A large delegation composed of 11 delegates from institutes from the Faculty of Science has made an extensive visit to China and enhanced Leiden’s influence in the Chinese academia, industry and local government.

The elderly accept may minor discomforts like stiffer muscles and getting tired more quickly, but they do want to go to their children's birthdays independently. Preventive elderly care helps people with that. The goal is to let people grow old while maintaining their self-reliance and independence…

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

What are the capabilities or limitations of traveling between islands and how does this reflect seasonal variation? Is it possible to show higher levels of connectivity between islands based on generated pathways between several sites on two separate islands?

Leiden researchers are helping develop safe COVID-19 vaccines.

The central theme of Rik Mom’s research group is to identify what the electrode-electrolyte interface looks like when electrocatalysis is taking place. Using specialized forms of Raman and X-ray spectroscopy, we study the chemical state and bonding environment of the electrode surface and near-surface…

The Delivery of Biotherapeutics research group is led by Prof. Matthias Barz and focusses on the synthesis and characterization of polypept(o)ids and their application in nanomedicine to improve existing therapies or enable novel diagnostic or therapeutic approaches.

In order to gain insight into the structure and function of the molecular complexes involved in chemotaxis, we use electron cryotomography (ECT). This technique allows us to directly study microbes in their native state at resolutions capable of visualizing individual proteins.

The CIGR comprises research groups from the Leiden Institute of Chemistry (LIC), the Leiden Academic Centre for Drug Research (LACDR) and the Leiden Institue of Physics (LION).

The Biomedical Metabolomics Facility Leiden (BMFL) is the core metabolomics facility of Leiden University and the Metabolomics and Analytics Centre (MAC).
