The Study Information Committee works to create a positive and accurate picture of the bachelor and master programs offered by the Institute of Biology Leiden (IBL). The committee consists of IBL staff members and study ambassadors. We reach out to future and current students, high school biology teachers,…

Wat wil je als docent nog meer dan studenten die goed voorbereid aan je vak beginnen? Maar hebben ze wel zin om hun kennis op te frissen? Een voorkennistoets kan helpen: daarmee bied je je studenten inzicht in wat ze nog wel en wat niet meer weten. Wij zijn nog een stap verder gegaan door studenten…

Museums, Collections & Society heeft een Adviesraad.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

D1.3 describes a set of five case studies relevant in the context of the EuDEco project. Case studies are considered relevant if they are initiatives focusing on the promotion of big data and data reuse or pilots facilitating data reuse in one form or the other. The case studies were expected to allow…

During the course of drug discovery translational steps are made.

Kinase inhibitors are key therapeutic agents, particularly in oncology, yet their clinical efficacy is often hampered by off-target effects and limited understanding of their cellular target profiles.

Endothelial dysfunction and microvascular diseases are key drivers of cardiovascular disease, the world's leading cause of death.

The cellular metabolism of immune cells constitutes an important part of their proper function and activation. Using T cells as an example, this phenomenon is highlighted by the metabolic reprogramming that occurs in these cells upon activation.

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

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.

Een ambtenaar die wordt vervolgd, kan worden ontslagen ondanks dat hij is vrijgesproken. En soms kan een burger die een vergunning heeft gekregen hier toch geen gebruik van maken zonder onrechtmatig te handelen jegens zijn buurman. Hoe gaat een rechter om met een uitspraak van een collega-rechter?

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

Zowel de universiteiten als het ministerie van Onderwijs willen dat studenten op tempo studeren. Hoe zorg je daarvoor? De bacheloropleiding Life Science and Technology heeft de laatste jaren een flinke vooruitgang geboekt.

Juridisch en pedagogisch advies van de Universiteit Leiden over het wetsvoorstel versterking rechtsbescherming in de jeugdbescherming. Het rapport is geschreven op verzoek van het Ministerie van Justitie en Veiligheid.

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.

De Universiteit Leiden stopt per direct met het experiment bindend studieadvies in het tweede studiejaar (BSA-2). Studenten moesten in BSA-2 binnen twee jaar 90 studiepunten halen, inclusief hun propedeuse.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

This thesis advances our understanding of lipid uptake, a vital first step in lipid metabolism, by developing innovative click chemistry-based tools to study how immune cells internalize lipids.

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

The ideas underlying this thesis are that lipidomics may improve the diagnosis of liver metabolic diseases, and can provide further insights into the underlying pathophysiology of these diseases.

This Thesis focuses on the design and synthesis of ADP-ribosylated compounds that can be applied in biological studies.

This thesis describes a study from both a theoreticaL and an experimental point of view.

Trillende koolstofmonoxide moleculen die zich binden aan het oppervlakte van een zoutkristal, stoppen binnen enkele milliseconden met bewegen. Wetenschappers hebben nu ontdekt dat dit voornamelijk komt door de emissie van elektromagnetische golven. De rol van de chemische binding met het oppervlakte…

The main aim of my Ph.D. thesis is to further explore the value of using early developing zebrafish larvae (up to 5 dpf) as a model to study anxiety-like behaviour and their pharmacological modulation with drugs.

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

This thesis seeks to investigate how cancer-associated mutations affect the pharmacological properties of selected GPCRs—primarily A2AAR and 5-HT2CR—through a combination of ligand binding assays, signaling readouts, kinetic profiling, and cellular functional assays.

Academici hebben op het gebied van inlichtingen geworsteld met de vraag onder welke voorwaarden internationale samenwerking op het gebied van inlichtingen plaatsvindt.
