Three speakers, three fascinating science stories and a well-filled lecture hall. The Niko Tinbergen Lecture had a successful restart on 10 December 2019.

We investigate the processes underlying the patterns. We aim to explain biodiversity by investigating the distribution, function, development, and evolution of body forms, as well as physiological and behavioural variety among species. We collaborate with those specialized in describing, archiving,…

This study explores the role of linguistic data in the reconstruction of Dolgan (pre)history by analyzing contact-induced changes and using them to infer information about the nature of the contact settings in which they occurred.

Are you interested in the neurocognitive and biological roots of learning, behaviour and emotions in children? If so, the programme in Applied Neuroscience in Human Development might be the specialisation you are looking for.

Delineating psychophysiological endophenotypes of social anxiety disorder

Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

Pathogenic bacteria are increasingly resistant to today’s antibiotics. Professor Gilles van Wezel seeks new forms of antibiotics in good bacteria that live in the soil.

This thesis explored the molecular pharmacological mechanisms of targeting CB2R via investigation of novel drug discovery concepts such as target binding kinetics, allosteric modulation and biased signaling.

This thesis describes the use of an activity-based proteomics method to study the endocannabinoid system.

N-acylethanolamines (NAEs), including N-arachidonoylethanolamine (anandamide, AEA), N-palmitoylethanolamine (PEA) and N-oleoylethanolamine (OEA), are signaling lipids that play an important role in different physiological process.

Protoplanetary disks are the gas and dust environments where planetary systems form around young stars. Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) this thesis analyses the gaseous molecular reservoir, using multiple tracers to resolve the 3D structure of protoplanetary…

This thesis describes the antimicrobial discovery strategy developed in our group, the den Hertog Group at the Hubrecht Institute. It includes a cultivation-based screening approach for novel antimicrobial agents from the source of fungi, and a bacterial time-lapse imaging approach for antimicrobial…

The cannabinoid CB2 receptor (CB2R) represents a promising therapeutic target for various forms of tissue injury and inflammatory diseases. Although numerous compounds have been developed and widely used to target CB2R, their selectivity, molecular mode of action and pharmacokinetic properties have…

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

During the course of drug discovery translational steps are made.

The disease acute myeloid leukemia (AML) is characterized by fast progression and low survival rates.

Diacylglycerol lipases (DAGLα and DAGLβ) convert diacylglycerol to the endocannabinoid 2-arachidonoylglycerol. Our understanding of DAGL function has been hindered by a lack of chemical probes that can perturb these enzymes in vivo.

The specialisation consists of 120 European Credit Transfer System (EC) points and includes courses and electives (30-60 EC) and and one or more research projects (60-90 EC).

The lipid matrix of the skin's stratum corneum plays a key role in the barrier function, which protects the body from desiccation. The lipids that make up this matrix consist of ceramides, cholesterol, and free fatty acids, and can form two coexisting crystalline lamellar phases: the long periodicity…

What are the phylogenetic relationships among the members of speciation bursts?

Intrigued by the way cells autonomously regulate their fate, we strive to understand and visualize cellular processes as the basis of Cell Signaling.

Glucocorticoids (GCs) are widely prescribed as anti-inflammatory drugs due to their well-established immunosuppressive effects.

The Leiden Institute of Chemistry (LIC) is the basis for research and collaborations of the Leiden chemistry groups. Chemistry is the central science enabling a healthy future in a sustainable society. Chemistry researchers at Leiden University take a fundamental approach in finding tailored solutions…

The aim of this project is to explore the use of statistical interaction models to quantify cross-omics and omics-drug interactions in large-scale clinical and experimental datasets

Microglia support the central and peripheral nervous system by forming the first line of defense against hazardous events. Microglia are increasingly acknowledged as critical players in neurodegenerative diseases, highlighting them as potential therapeutic targets.

The idea that modern humans displaced Neanderthals because they were better protected against toxic smoke components is now under fire. An earlier study that put forward this suggestion has now been refuted by genetic research by scientists from Leiden and Wageningen. This new research was published…

Mashaghi lab conducts research at the interface of physics, engineering and biomedicine. We develop and use theoretical and experimental approaches to address basic and applied research problems.

Patients with the same illness often receive the same treatment, even if the cause of the illness is different for each person. This represents a new step towards ultimately being able to offer every patient more personalised treatment.

Antibiotic-resistant bacteria are a major problem worldwide. Molecular biologist Changsheng Wu explored innovative methods of developing new antibiotics more simply and more easily. He also discovered a new type of antibiotic.

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…
