Three Psychology students will present a poster of their thesis research on Alzheimer’s and dementia at the international conference AAIC Neuroscience Next. ‘I remind myself to recognise - without fear or shame - when I don't know something.’

Worldwide, countries are barely prepared for major borderless crises such as extreme natural disasters or other unexpected calamities that destabilise society, Professor of Political Science, Arjen Boin, warns. In his inaugural address on 23 October he makes some recommendations.

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…

Metastasis is responsible for over 90% of cancer-related deaths and arises from the ability of a small subset of tumor cells to detach from the primary tumor, overcome multiple biochemical and mechanical barriers, disseminate through the body, and colonize distant organs.

An overview of the research at the Biologics Formulation group

The Leiden University Medical Center (LUMC) is committed to improving healthcare and the health of individuals. The LUMC staff put this mission into practice on a daily basis with their leading research, cutting-edge teaching and optimal, innovative healthcare.

By carrying out fundamental research and providing excellent education, universities become a breeding ground for innovation and entrepreneurship.

How do protein modifications work together to repair DNA, and what can we learn about these interactions to better understand disease?

Leiden Early Drug Discovery & Development (LED3) is a multidisciplinary research network at Leiden University dedicated to advancing innovative approaches in early drug discovery and development. The initiative brings together 58 principal investigators from four institutes—the Institute of Biology…

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)…

A consortium of research groups, including that of LACDR professor Erik Danen, will use an NWO Perspective grant of nearly five million euros to build a universal standard for organ-on-chip models. They aim to stimulate the application of these chips in the biomedical and pharmaceutical industry. Danen…

The Novel chemical modalities research group is headed by Assistant Professor Sebastian Pomplun. Sebastian started at the division of Medicinal Chemistry within the LACDR in September 2021. His lab develops technologies for the discovery of novel chemical modalities that can address challenging drug…

Integrins play an essential role in multicellular life by connecting cells to the extracellular matrix.

Analysis of drug adversity

Steffen Brünle's group investigates G protein-coupled receptors (GPCRs). These essential membrane proteins are prime targets for therapeutic drug development in disease and cancer treatment.

In this Educatips collumns, Child and Education Studies lecturers share their key insights about teaching. This month: Rachel Plak and Karlijn Pieterse wanted to better prepare students in the course Autism and Diagnostics for clinical practice. That's why they introduced a new type of assignment.

Luis is a third-year bachelor’s student Security Studies. During his elective space, he did an internship at the German Ministery of Labour and Social Affairs.

The research in the Biosyn group is focused on the design, synthesis and function of the four major types of biomolecules: nucleic acids, carbohydrates, peptides and lipids and hybrid structures thereof. These biomolecules and their derivatives are used in drug discovery and chemical biology, to develop…

We investigate the molecular basis underlying health and disease and provide answers to existing and emerging health problems. Within this theme, we study diseases ranging from rare genetic disorders to cancer and infectious diseases. We make use of a wide variety of model systems and pursue diverse…

The goal of hit and lead optimization is to optimize suitable chemical starting points that can modulate a drug target. The methods and technologies used are similar to those in Hit Discovery, but once the compound has shown activity in an animal model, it moves from 'hit' to 'lead.'

Erik Danen is looking at how to inhibit tumours that do not respond well to medicine – and he is making some headway. The Professor of Cancer Drug Target Discovery studies the interaction between tumour cells and their surroundings. Inaugural lecture on Friday 10 May.

The Leiden Academic Centre for Drug Research (LACDR) is a centre of excellence for multidisciplinary research on drug discovery and development.

In this research group, headed by Laura Heitman, novel receptor concepts in drug discovery are studied, aiming to increase the effectivity of medicines. Many drugs act via so-called G protein-coupled receptors (GPCRs) and therefore our research is mainly focused on understanding and improving drug-receptor…

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.’

Chromatin is an ubiquitous protein-DNA complex that forms the structural basis of DNA condensation in all eukaryotic organisms.

This thesis focuses on data found in the field of computational drug discovery. New insight can be obtained by applying machine learning in various ways and in a variety of domains. Two studies delved into the application of proteochemometrics (PCM), a machine learning technique that can be used to…

Cytotoxic T-cells (CTLs) are involved in the clearance of viruses and killing of tumor cells.

High throughput microscopy

Pericytes, the mural cells of blood microvessels, are important regulators of vascular morphogenesis and function that have been postulated to mechanically control microvascular diameter through as yet unknown mechanisms.

Projects within the theme ‘Computational Biology’ aim to employ mathematical or computational dynamical modelling approaches to discover novel concepts that are important for drug development.

This dissertation aims to advance understanding of amoeboid single cell migration under the influence of changing physicochemical environmental properties. The particular focus is on the relatively unknown influence of differing physical properties in the extracellular environment, such as the migratory…

We use DNA strands to stabilize few-atom silver clusters, which show unique optical and chemical properties. This thesis involves the study of these constructs for various applications.

The predication of the effect (efficiency and toxicity) of a drug in a patient is very important in (i) clinical decision support and (ii) the development of novel drug treatments. We apply our technology and methods to find biomarkers for key disease pathways and toxicity in clinical studies and in…
