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…

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.

Microbial Sciences' contribution to the Biodiversity & Evolution research theme focuses on understanding how bacteria sense and respond to their environment, and how bacterial diversity and evolution is influenced by cooperative and antagonistic interactions taking place between microbes.

Pathways of toxicity

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.

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.

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

Cancer represents a formidable current and future global health challenge. The LUMC medical research profile Cancer Pathogenesis and Therapy charges this challenge by developing and implementing innovative patient-tailored, multimodal diagnostic methods and treatment modalities.

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…

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

The current projects of the Molecular Physiology group focus on proteins of the endocannabinoid system, kinases and antibacterial targets. MSc- and BSc-students can contact Jessica van Krimpen-Kraaijenoord to apply for research internships.

The 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.

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 Biomedical Metabolomics Facility Leiden (BMFL) is the core metabolomics facility of Leiden University and the Metabolomics and Analytics Centre (MAC). We offer a highly structured environment for advanced MS-based metabolomics studies and build on fully validated, state-of-the-art assays that each…

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 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.

The close interaction between organic chemi stry and biology goes back to the late 18th century, when the modern natural sciences began to take shape. After synthetic organic chemistry arose as a discipline, organic chemists almost immediately began to pursue the synthesis of naturally occurring compounds,…

Born in Europe roughly 100 years ago, quantum physics brought forth a veritable technological revolution through semiconductors, lasers, fibre optics, and many other technologies that are today ubiquitous in our lives. Now, during the second quantum revolution, Europe can take the lead once more in…

The aim of this thesis was to develop novel treatment strategies for different types of eye melanoma utilizing zebrafish models. We first establish orthotopic and ectopic xenograft models for uveal and conjunctival melanoma by engraftment of the immortalized cells derived from these tumors into zebrafish…
