For medical research, researchers often recreate tissue in the lab. Organ-on-a-chip technology emulates organs, right down to the blood that flows through them, thus creating a realistic test model for drugs or research into disease processes. Researchers from the LUMC are coordinating an NWO Gravitation…

An objective of this research was to achieve direct, well-defined and non-rate-limiting electron transfer between respiratory enzymes and the electrode surface by means of 'Q-wires'.

Within this thesis the central stage is taken by the discovery and investigation of transglycosylation of sterols. First, investigation focuses on the development of a method to accurately detect and quantify glucosylated metabolites in biological materials.

Cardiovascular syndromes are the major cause of death in Western societies.

Organs and tissues grown in the lab may in the future be able to cure people with organ failures. Micha Drukker, professor of Stem Cells, Developmental Biology and Technology for Innovative Drug Research, is convinced that the use of stem cells will make this possible. He will deliver his inaugural…

Two bacterial species team up inside the plant root system to rescue their host from fungal infection. This was discovered by a team of microbiologists and bioinformaticians from the Netherlands Institute of Ecology, Wageningen University, and the Institute of Biology Leiden. They also identified the…

In July, 2018, the Institute of Biology Leiden hosted the 11th conference of the Zebrafish Disease Models Society (ZDMS), an international association dedicated to the advancement of basic and clinical research using zebrafish disease models. More than 350 researchers from all over the world gathered…

A combination of two potential drugs gives hope of a 'super blockage' of an over-active immune system, Leiden researchers report in Nature. The breakthrough came from the crystallisation of a membrane protein.

Although coeliac disease, an autoimmune disorder that makes you gluten intolerant, occurs in 1% of the population, its diagnosis is often delayed or completely overlooked. To prevent health problems, this must change. That is what Professor of Paediatrics Luisa Mearin said at her inaugural lecture on…

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

Professor by Special Appointment of Clinical Neuropharmacology Geert Jan Groeneveld will deliver his inaugural lecture entitled ‘The importance of the biomarker’ on 11 March 2022. According to him, new genetic knowledge will revolutionise drug research.

Meniere’s disease, a disorder of the inner ear, was first described back in 1861, but there’s still no good test or treatment for it. Tjasse Bruintjes, Professor by Special Appointment of Ear, Nose and Throat Surgery, wants more attention for this mysterious disease. And he wants to tell his fellow…

Leiden Scientists are getting prepared to tackle future epidemics. A group of scientists led by Dr. Alireza Mashaghi has used innovative engineering approaches to make the first “Lassa Hemorrhagic Syndrome on-a-Chip”. World Health Organization has listed Lassa fever among diseases that pose the greatest…

Exploiting metabolic vulnerabilities to identify anticancer compounds in zebrafish synthetic lethality screens.

Do humans and zebra finches share cognitive mechanisms that are important for speech perception?

How does FoxP1 affect auditory perception on a behavioural and genomic level?

How can the Netherlands be better prepared for infectious diseases transmitted by mosquitoes. The Dutch Research Council (NWO) has awarded almost 9 million euros for this research. Maarten Schrama from the Institute of Environmental Sciences CML coordinates the input of Leiden University within the…

By measuring proteins in tears, ophthalmologists can more easily diagnose dry eyes (Dry Eye Disease). Peter Raus, a Belgian ophthalmologist and PhD student at the Institute of Biology Leiden, developed a new method for protein determination in tear fluid. The technique is also promising for the early…

New funding allows IBL-researcher Herman Spaink to purchase a measurement device for more studies on human diseases such as cancer and tuberculosis using zebrafish as the model system.

Aceruloplasminemia is a very rare, genetic disease accompagnied with iron accumulation that causes movement disorder and brain damage at early age.

Exceptional collaboration between physicians is needed to better understand and treat autoimmune diseases that cause inflammation in various organ systems.

Parkinson's disease is the second most common neurodegenerative disease in the world. One of its symptoms is the loss of dopaminergic neurons in the substantia nigra pars compacta.

Patients with the same illness often receive the same treatment, even if the cause of the illness is different for each person. This represents a new step towards ultimately being able to offer every patient more personalised treatment.

They can play a role in metabolic disorders and can break down tough plant fibers: β-glycosidases are enzymes that play many roles in nature. Fredj Ben Bdira changed these enzymes in order to enhance the production of clean energy and to improve the treatment of patients with metabolic diseases.

On 3 April, Professor Syed Faisal Ahmed from the Leiden University Medical Center (LUMC) will give his inaugural lecture ‘Strength in Numbers’. He will emphasise the benefit of registries to rare disease research.

In the Netherlands, 1.55 million people suffer from cardiovascular diseases. Yet, acute cardiovascular events, such as a heart attack or stroke, often occur unexpectedly. That is because many people do not know they are at risk for such an event. Immunological researcher Amanda Foks and her colleagues…

A theoretical project on the insights gained by human (including infant), nonhuman animal and computational studies on artificial grammar learning; identifying the critical questions for future research by developing novel experimental and computational approaches to address these issues.

Due to the increasing resistance to certain antibiotics, the life-threatening condition sepsis is becoming harder to treat. For her PhD project, Leiden pharmacologist Feiyan Liu used mathematical modeling to find out how antibiotics can be used more effectively to cure sepsis.

Alireza Mashaghi and his research team have created a new framework to understand shapes of proteins and DNA. With this framework, many diseases can be understood better.

Mapping of bacterial genomes to combat infectious diseases

Can thrips resistance in strawberry be explained based on secondary metabolite profiles and plant morphological traits?

How is vegetative development regulated in plants and how does this affect a plant’s life history strategy?

We aim to engineer streptomycetes to fully exploit their potential for natural product productions, by a rational design and evolution approach.

Cardiovascular diseases are among the most frequent causes of death in the world. The main underlying pathology of cardiovascular diseases is the development of atherosclerosis in the medium and large-sized arteries.

Fake news about ‘patient zero’ and hyperbolic headlines warning about the ‘yellow peril.’ Leiden researchers have spotted fake news galore about coronavirus as well as racial stereotypes about the Chinese. How harmful is this?

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.
