In dit artikel onderzoeken Layla van Wieringen, Daan Weggemans en Marieke Liem hoe rechts-extremistische ouders de ideologische socialisatie van hun kinderen bespreken en rechtvaardigen.

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

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.

Nanoparticles can be used as delivery systems for both small molecules and macromolecules such as proteins, peptides or oligonucleotides. This thesis focuses on the use of liposomes, nanometric vesicles formed by a lipid bilayer enclosing an aqueous core. Liposomes are highly versatile delivery syst…

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

Leidse chemisch biologen, onder leiding van dr. Mario van der Stelt, hebben stoffen ontdekt die ontstekingsprocessen in de hersenen kunnen verminderen. Daarmee is een eerste stap gezet in de ontwikkeling van potentiële geneesmiddelen voor de behandeling van hersenziekten zoals de ziekten van Alzheimer…

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.

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.

Why do sexual violence policies still fail to systematically address men and masculinities, when the need for cultural change among men has been central in public debates since #MeToo?

De docenten van de cursus Gendergerelateerd geweld zijn Marieke Liem en Mischa Dekker.

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…

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.

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…

Van oefeningen om gezonder te werken tot praktische tips over lekker slapen. Studenten en medewerkers die deelnemen aan de Healthy University Workshops op 18 of 19 oktober krijgen persoonlijke tips die goed bij hun situatie passen.

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.

In this thesis, single-cell approaches were applied to characterize the impact of aging on the immunological B cell landscape in different models of atherosclerotic cardiovascular disease, with the goal to identify and study new B cell-associated biomarkers and therapeutic targets to halt atherosclerosis…

Despite substantial progress in understanding tuberculosis (TB), the eradication of the TB epidemic is still far from reach.

Internationaal geadopteerde kinderen gebruiken niet meer medicijnen dan hun niet-geadopteerde leeftijdgenoten.

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.
