Currently, several successful vaccines are available. However, for pathogens with a highly variable genetic composition, and for which serum IgG antibodies are not a useful correlate of protection, effective vaccines are yet to be developed.

The emergence of complex diseases resulting from abnormal cell-cell signaling and the spread of infectious diseases caused by pathogens are significant threats to humanity. Unraveling the dynamic mechanisms underlying cell-cell signaling and infectious disease spreading is crucial for effective disease…

How can Europe lead the way in vaccine development that is fast and for all? To answer this pressing question, Professor of Vaccinology Meta Roestenberg is holding a panel session on 14 July at the EuroScience Open Forum in Leiden.

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.

Mapping of bacterial genomes to combat infectious diseases

Fourteen bachelor’s and master’s students are representing Leiden University in this year’s International Genetically Engineered Machine competition (iGEM). Their plan: to create a kit that can be used to quickly identify infectious diseases in case of an outbreak.

Development & Disease is one of the four research themes of the Institute of Biology Leiden.

Animal Sciences’ contributions to the Development & Disease research theme include the mechanisms and evolution of embryonic development, the development of cognitive mechanisms, and animal models for understanding mechanisms of human disease.

Bone research provides plenty of detailed data about the health of a person or a group. This data is not only used to reconstruct the past but also to fight disease today.

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…

How can zebrafish models be used to gain a better understanding of host-pathogen interaction mechanisms and to screen new drugs for infectious disease treatment?

To explore the potential of marine microorganisms as producers of novel antimicrobial agents and as bioprotectants in aqua- and agriculture, using an integrative, ecology-based strategy for bioprospecting.

How can the development of constrictions in the blood vessels be reversed?

The changes that humans are making to the landscape are beneficial for mosquitoes that spread diseases such as Zika, chikungunya and dengue. This is what biologist Maarten Schrama and his colleagues write in the journal Nature Scientific Reports. ‘If we know in which living environments mosquitoes thrive…

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

Health workers have always sought ways to fight disease in vulnerable groups in the population. It is now clear that such research also benefits more prosperous countries. African worm infections and innovative thermometers have shown Leiden researchers how to fight diseases of affluence and keep health…

TRANSAUTOPHAGY is a European COST action to promote multidisciplinary research on autophagy and translation of knowledge to applications.

What is the role of cell wall-deficiency in the persistence of tuberculosis?

How can Staphylococcus aureus bacteria subvert the host immune system?

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

Control of infectious diseases poses continuous challenges for human health.

How is inflammation in tuberculosis controlled by interplay between autophagy and inflammasome signalling?

Studying the impact of urbanisation on the respiratory health of past Dutch populations (1200-1850 CE).

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

Assessing and implementing new diagnostics strategies for stratifying patients

Aim of the proposal is to develop lugdunomycin into a drug candidate able to treat infectious diseases caused by multi-drug resistant pathogens.

Decision support tool for cell therapy commercialization and business development

Who benefits from CXCR/CXCL chemokine signaling during infection: host or pathogen?

Having a chronic somatic condition can result in a variety of impairments in patients’ daily lives, including not only physical complaints such as pain, itch, and fatigue, but also problems of negative mood and impairments in social relationships. Next to disease characteristics, individual difference…

Tuberculosis bacteria and other intracellular pathogens use cells of our immune system as Trojan horses to spread into tissues. Annemarie Meijer, professor of immunobiology, explains how research into innate defence mechanisms using zebrafish inspires novel strategies for infectious disease treatmen…

Inflammatory skin diseases such as psoriasis and atopic dermatitis can severely impact both the physical and social aspect of a patient’s life. Aberrant inflammatory responses are thought to be a major causative factor in these disorders, but an abundance of different factors contribute to the development…

How can zebrafish research help understanding human diseases?

Antimicrobial resistance (AMR) is the phenomenon that pathogens become insensitive to the antibiotics that we use against them. A growing number of pathogens is becoming resistant, with methicillin-resistant S. aureus (MRSA) as the most famous example. But while the threat of AMR represents a slow-moving…

This thesis describes biochemical investigations of glucocerebrosidase (GBA), the lysosomal β- glucosidase that is deficient in Gaucher disease (GD).

Our immune system protects us against disease, but every now and then, something goes wrong: an enemy invades our bodies or our immune system attacks our own cells and we become ill. Doctors and researchers at the Leiden University Medical Center (LUMC) want to be able to manipulate the immune system…

Microbial Sciences'contribution to the Development & Disease research theme is to perform world-class research to understand cellular morphogenesis, growth, development and virulence of microbes.

This is an Erasmus+ International Credit Mobility project of the Leiden University Medical Center with Nagasaki University.

The infectious diseases malaria and tuberculosis are responsible for 2.1 million deaths every year. Leiden researchers are currently testing a new tuberculosis vaccine.

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…

This minor focuses on the relationships between behaviour, health and illness.

How do mycobacteria subvert the defenses of host immune cells?
