Er is bovendien apparatuur beschikbaar voor histologie, met inbegrip…

We showed that constitutive and inducible chemical and morphological defenses against Western flower thrips differ between tomato and chrysanthemum plants.

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

Endocannabinoids are lipid messengers that modulate various physiological functions by activating the cannabinoid CB1 and CB2 receptors. While the metabolism of endocannabinoids and their action at the CB receptors is fairly well studied, the molecular mechanisms governing their release and transport…

With an emphasis on developing novel miktoarm star polymers termed PeptoMiktoStars, this thesis leverages asymmetric polymeric polypept(o)ide frameworks to advance their effectiveness in delivering hydrophobic drugs and nucleic acids.

Metabolomics is a powerful tool that can provide a comprehensive insight into the complexity of human biology and the pathophysiology of diseases. By analyzing the metabolome, which refers to the complete set of small (endogenous) molecules (with a mass <1500 Da) present within a given biological system,…

During the course of drug discovery translational steps are made.

Er is veel persaandacht voor het onderzoek van het Levend Lab. Hieronder een kleine greep uit de nieuwsberichten. En bekijk ook vooral de Zembla-aflevering over het Levend Lab.

Naast de 2 TOP grants heeft het LIC ook nog 4 ECHO’s binnengehaald voor dr. Francesco Buda, professor Gijs van der Marel met Jeroen Codée, dr. Dmitri Filippov en professor Gilles van Wezel.

Voor Molecular Science and Technology is de matchingsactiviteit een verplicht onderdeel van de inschrijving.

Kunstmatige fotosynthese heeft als doel om via chemische processen zonne-energie om te zettn in brandstof. Semi-kunstmatige fotosynthese is een hybride aanpak waarbij chemische maar ook biotechnologische processen worden gebruikt. Wij hebben als doel om een hybride systeem te ontwikkelen met behulp…

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

Adenosine is an endogenous ligand which exerts its action by activating adenosine receptors (ARs), while its circulating levels are controlled via a variety of mechanism and proteins, amongst others the equilibrative nucleoside transporters (ENTs).

Taxonomy as a science has accumulated data and knowledge for more than 250 years.

Diacylglycerol lipases (DAGLα and DAGLβ) are responsible for the biosynthesis of the endocannabinoid 2-arachidonoylglycerol (2-AG) in the brain and peripheral tissues. Selective DAGLβ inhibitors have been proposed as a potential treatment for inflammatory diseases with reduced potential for central…

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

The thesis is about how auxin and AGC kinases regulate male fertility. The main AGC kinases studied in this thesis is PDK1, PDK2 and AGC1.5, AGC1.7.

Global healthcare is on the verge of an antibiotic availability crisis as bacteria have evolved resistance to nearly all known antibacterials. Identifying new antibiotics that operate via novel modes-of-action is therefore of high priority.

Glucocorticoids are potent anti-inflammatory drugs widely used clinically to treat various inflammatory and immune conditions. However, two main clinical problems limit their use. GCs trigger severe side effects and they induce acquired glucocorticoid resistance, especially during chronic systemic treatment…

This thesis explores different avenues to develop insurmountable antagonists for CC Chemokine Receptors, such as CCR1, CCR2 and CCR5.

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…
