In vitro disease models play a fundamental role in drug research. They enable the systemic identification and validation of disease mechanisms and the discovery of possible drug targets. However, more than often, drug candidates that are identified in vitro fail in the later clinical stages of drug…

The objective of the Next Generation ImmunoDermatology project (funding NWO, program NWA-ORC) is to deep profile the immune-mediated inflammatory diseases: i) atopic dermatitis (AD), ii) cutaneous lupus erythematosus (CLE) iii) chronic spontaneous urticaria (CSU) iv) hidradenitis suppurativa (HS) v)…

Chronic inflammatory skin diseases such as psoriasis and atopic dermatitis affect both the physical and psychological well-being of millions of patients, leading to persistent symptoms like itchiness and sleeplessness. These conditions often result in decreased productivity and quality of life overall,…

Pharmacogenetics is nowadays increasingly incorporated in the clinic to better predict pharmacokinetics and optimize dosing regimens of drug treatments. While this approach has been successful and improved our prediction of drug metabolism, drug levels within patients may still commonly deviate between…

No, this isn’t about a Star Wars Alliance that wants to suppress The Resistance. Rather, the EPIC Alliance brings together scientific experts from seven countries to address the growing threat of antibiotic resistance. Leiden professor Nathaniel Martin is part of the 11-member consortium.

Methods of treatment for chronic illnesses are limited. Doctors and researchers at Leiden University Medical Center (LUMC) and Leiden University are working on new therapies as an alternative for organ transplants. The goal is to cure the illnesses by restoring organs to their original function. Stem…

This is an Erasmus+ International Credit Mobility project of the Faculty of Science with the Taras Shevchenko National University of Kyiv.

From black holes to artificial intelligence and from drug research to data science: welcome to the fascinating world of the Faculty of Science. Our researchers, students and guests regularly give public lectures about their work. You are welcome to attend.

Exploring metabolomics-based biomarkers for diagnosis and treatment response monitoring of community-acquired pneumonia

There are eight institutes at the Faculty of Mathematics and Natural Sciences:

This project is part of the Next Generation ImmunoDermatology (NGID) consortium, which focuses on the comprehensive phenotyping of six different immune-mediated inflammatory skin conditions. A common factor contributing to these diseases is a dysfunctional skin barrier. The skin barrier function is…

This thesis describes our search to identify and understand possible regulatory mechanisms of integrin α6β4 in cell-matrix adhesion and intracelular signaling.

A research goal for ABS is to develop miniaturized platforms for research in (stem)cell, in-vitro systems and application in clinical and preventive research. Combined with the high throughput, this development will make it possible to study the dynamics of pathogenesis in human and cellular models…

Ceramides (CERs), cholesterol, and free fatty acids (FFAs) are the main lipid classes in human stratum corneum (SC, outermost skin layer), but no studies report on the detailed analysis of these classes in a single platform.

Tuberculosis is a major global health problem caused by the Mycobacterium tuberculosis complex, claiming more than a million lives annually.

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…

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…

The Translational Immuno-Pharmacology group works on translating the efficacy of anti-infective therapy from preclinical (e.g. in vivo) to clinical, and is led by Rob van Wijk. Infectious diseases, such as tuberculosis, are in constant need of new therapies that work better, faster, and with less risk…

For effective cancer immunotherapy by vaccination, co-delivery of tumour antigens and adjuvants to dendritic cells and subsequent activation of antigen-specific cytotoxic T cells (CTLs) is crucial. In this study, a synthetic long peptide (SLP) harbouring the model CTL epitope SIINFEKL was encapsulated…

Antibiotics are a class of medicine most people take for granted. But pathogenic bacteria are becoming more and more resistant to our antibiotics, and this poses a great challenge for future treatments. There is thus a great societal need to identify new molecules that can address new targets and be…

Enabling volume-restricted metabolomics using next-generation microscale analytical tools.

BACKGROUND: Explant human skin equivalents (Ex-HSEs) can be generated by placing a 4mm skin biopsy onto a dermal equivalent. The keratinocytes migrate from the biopsy onto the dermal equivalent, differentiate and form the epidermis of 1(st) generation Ex-HSEs. This is especially suitable for the expansion…

OBJECTIVES: To determine whether the lipid/protein ratio and the total dry SC mass per surface area are related with the skin barrier function of controls and AE patients.

New drugs for use as tuberculosis (TB) treatment are needed due to the constrains of classical antibiotics against TB and the rise of antibiotic-resistant strains, making TB a harder and harder disease to treat.

Atopic dermatitis (AD) is a common inflammatory skin disorder characterised by various epidermal alterations. Filaggrin (FLG) mutations are a major predisposing factor for AD and much research has been focused on the FLG protein.

Designing and synthesizing high-affinity ligands for a given drug target have always been among the more important challenges in the drug discovery process.

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.

Repairing organs, tissues and cells to fight chronic diseases.

With the powerful electron microscopes at NeCEN we study abnormalities in cells of blood vessels in cardiovascular disease, the interaction between pathogens and hosts in infectious diseases, molecular processes that cause cancer and the interaction between drugs and target proteins. Drug development…

Adenosine diphosphate ribosylation (ADP-ribosylation) is a fascinating post-translational modification (PTM) that plays a role in a variety of cellular processes and is associated with several diseases, including cancer and viral infections.
