Atherosclerosis is the main underlying pathology of cardiovascular disease. Atherosclerosis is caused by an immune response which is directed against (modified) lipoproteins which accumulate in the vessel wall.

According to the amyloid cascade hypothesis, accumulation of beta-amyloid (Aβ) peptides initiates the pathological cascade in Alzheimer's disease (AD).

The ADAPTED (Alzheimer's Disease Apolipoprotein Pathology for Treatment Elucidation and Development) project is a major new initiative to investigate an area of Alzheimer's Disease (AD) research which has previously received little attention. The project aims to improve understanding of the function…

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.

The development process of any software has become extremely important not just in the IT industry, but in almost every business or domain of research.

In the programme group Parenting, Child Care and Development we examine in what way parents (mothers and fathers) and allo-parents (e.g., professional caregivers) influence children’s development, wellbeing and health. The main focus is on children’s social-emotional development and the prevention of…

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…

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…

This edited book presents case-studies and reflections on the role of languages and their analytic study in development practices across four regions: Africa, Asia, Australia, and the Pacific.

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…

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.

Do you want to learn how to prevent child problems by optimising caregiving? Would you like to advise parents, professional caregivers and policy makers on caregiving-issues? In that case the master’s specialisation Parenting and Child Development is the ideal choice for you!

What is the relation between brain development and social and cognitive development across childhood, adolescence and adulthood?

In Microbial Sciences, we perform multidisciplinary research to understand the structure and function of microbes at all levels of biological organization, from small molecules and cellular structures at atomic resolution to multicellular communities.

The more opportunities a child has to learn and develop, the stronger his or her future position in society. Leiden University investigates how the brain picks up information, and how learning processes can be influenced positively.

The LUMC has a longstanding tradition researching the role of the immune system in infectious diseases, transplantation and auto-immune diseases.

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…

The research of this PhD project can be subdivided into two main disease areas: migraine and stroke. For both we will be investigating how artificial intelligence (AI) and machine learning (ML) techniques can be used to study these afflictions, their (early) detection, and their potential treatment.

Students with learning problems experience difficulties in reading, writing, and content-area learning into and throughout their secondary-school years

What is the effectiveness of (booklet or online) self-help programmes for people with somatic stressors and depressive symptoms? What works best for whom? How to improve motivation and adherence?

Africa is rising and increasingly seen as a potential market by economic actors from Africa and the rest of the world. What is the interrelationship between governance, entrepreneurship and inclusive development?

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…

How can teachers best learn from each other and develop? Jacobiene Meirink is conducting research on professional development for teachers in secondary education. She is particularly interested in how teachers collaborate on and learn from the development of teaching programmes. More insight into effective…

When a bacterium becomes more resistant to one antibiotic, it sometimes becomes more sensitive to another. To better understand this interaction, researchers from the Leiden Institute of Biology (IBL) and the Leiden Academic Center for Drug Research (LACDR) under supervision of Daniel Rozen and Coen…

We cover the entire spectrum from target identification to the evaluation of the efficacy and safety of novel medicines in clinical practice.

On 18 May 2011, Dr. Ben Knapen, Minister for European Affairs and International Cooperation, delivered the annual Van Vollenhoven Lecture on “Rule of Law and Development”.

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…

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.

Nature is a never-ending source of inspiration for the researchers at the Institute of Biology Leiden (IBL). Based on a better fundamental understanding of nature, they are able to seek solutions in the area of health and biodiversity. The theme of IBL is ‘Harnessing biodiversity for health.’
