The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

The zebrafish is a promising vertebrate model organism in early drug discovery and development.

Glycosidases are essential in fundamental biological processes and are responsible for the degradation of most (oligo)saccharides, glycolipids and glycoproteins.

Glycoside hydrolases (glycosidases/GHs) are widely abundant enzymes in all kingdoms of life and are important biocatalysts that catalyze the hydrolysis of glycosidic linkages in oligo/polysaccharides, glycoproteins and glycolipids with tremendous efficiency

Schistosomiasis is an acute and chronic disease caused by blood dwelling parasitic trematodes of the genus Schistosoma, and it is classified as the second most socioeconomically devastating parasitic disease, second only to malaria.

Oogst na oogst binnenhalen van rijstveld, zonder nieuwe rijstplanten te zetten? Door een ontdekking komt dit scenario misschien wel dichterbij. Leidse wetenschappers hebben een gen ontdekt waarmee ze eenjarige planten na het bloeien opnieuw laten groeien, in plaats van dat de planten sterven. Publicatie…

Leidse biologen hebben aangetoond dat een gen dat aanwezig is in planten, dieren en gisten wel degelijk een belangrijke rol speelt in planten, al werd daar jaren anders over gedacht. Zonder het gen blijkt de ontwikkeling van vaatweefsel in planten niet goed op gang te komen. Publicatie in Nature Plants…

Tot wel 50% van de mensen met de ziekte van Parkinson ontwikkelt na verloop van tijd cognitieve achteruitgang; deze studie onderzoekt het gebruik van ‘oefeneffecten’ op neuropsychologische tests als een vroege voorspeller van cognitieve achteruitgang.

The overarching goal of this PhD thesis is to investigate the taxonomic and functional diversity of yeasts in the wheat phyllosphere and their interactions with the mycotoxigenic fungal pathogen Fusarium graminearum.

Bio-farmaceuten kunnen vanaf nu modelcodes en datasets uit een databank opvragen om de dosering en het effect van nieuwe medicijnen beter te kunnen voorspellen.

This thesis aimed to investigate core cross-linked polymeric micelles (CCPMs) and expand their potential for the delivery of hydrophobic drugs and co-factors.

How are new drugs developed? This question is central to the Minor Modern Drug Discovery (MDD), which covers the entire trajectory from disease to drug molecule and vice versa. The various research groups involved offer a complementary and interdisciplinary perspective by connecting the diverse subjects…

Zonder een gewas opnieuw te zaaien toch nakomelingen produceren, die zelfs groter kunnen zijn dan de ouderplant. Volgens Leidse onderzoekers is dat mogelijk door het overstimuleren van één gen. Daarmee verjongt een cel en gaat deze terug naar de embryonale fase.

The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

Onderzoekers van de Universiteit Leiden gaan een nieuwe manier ontwikkelen om de biomarkers van de ziekte van Alzheimer te bestuderen. De aanpak focust zich op de moleculaire boodschappers van de cellen. Het project, geleid door Thomas Hankemeier en gecoördineerd door Yuliya Shakalisava (Leiden Academic…

Lipid signaling is an essential biological event/process in a plethora of pathophysiological conditions. The underlying idea of this thesis is that many of the roles and the complex interplay of the individual signaling lipids in inflammatory processes and related conditions in health and disease is…

A convolutional neural network (CNN) is a biologically inspired algorithm, highly capable at processing images and videos.

Accurate prediction of the unbound drug concentration-time profile at the CNS target site is crucial for the assessment of the right drug concentration-effect relationship. PBPK models have supported the PK prediction of the CNS target sites and the translation of PK data between species and between…

Glycosidases are important enzymes in the turnover of polysaccharides and glycoconjugates, and are involved in a range of human pathologies including genetic disorders such as Gaucher and Pompe disease, but also in various cancers.

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.

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,…

Cardiovascular diseases are still a major concern for the global health.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

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.

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.

This multidisciplinary minor provides students with knowledge on how and why humans became the way they are. The minor focuses on the evolution of the species Homo sapiens from other hominin lineages and animal ancestors, and on the various factors shaping this process. Not only is human evolution of…

Met elektronspins hebben natuurkundigen het bindingsproces onderzocht van het eiwit α-synucleïne, dat wordt geassocieerd met de ziekte van Parkinson. Wat blijkt is dat het eiwit op een verrassend efficiënte manier bindt aan een hersenmembraan. Met deze in Leiden ontwikkelde methode hebben de onderzoekers…
