Engineering innate immunity for therapy
Immune system defends our body against pathogens and cancerous cells, but excessive immunity can in turn lead to tissue damages and diseases. For example, scratching the surface of the eye ignites an immune response that aims at preventing infection but can also lead to edema, angiogenesis and eventually…

RESTORING T-CELL HOMEOSTASIS BY IN VIVO MANIPULATION OF DENDRITIC CELLS
The loss of T-cell homeostasis and tolerance towards self-antigens is the underlying cause of autoimmune and inflammatory diseases like atherosclerosis, rheumatoid arthritis or type I diabetes. Traditionally, the treatment of these diseases consisted on systemic immune suppression, which can entail…

Diminishing tolerance in the Netherlands threat to liberal society
The Upper and Lower Houses of the Dutch Parliament are struggling with how tolerance should best be interpreted. As a result, the freedom in the Netherlands for people who hold alternative views is diminishing. This is Floris Mansvelt Beck’s conclusion on the basis of his PhD research. Defence on 2…

Cleaning up tuberculosis and salmonella infections
The cellular recycling system in zebrafish is capable of eating harmful bacteria and thus resist infections such as tuberculosis and salmonellosis. That is written by Leiden biologists from the group of Annemarie Meijer. Stimulating this form of defence could be used in new treatment methods against…

‘Skin injection could allow us to vaccinate up to five times more people from the same supplies’
The current COVID-19 vaccination campaign involves injecting the vaccine into muscle tissue, but injecting a smaller amount of vaccine in the skin might also provide good protection. The #wakeuptocorona crowdfunding campaign has enabled Anna Roukens (LUMC) to examine the safety and efficacy of vaccination…

Islam and Society
Knowledge of Muslim societies is essential to function in a globalised world and to fully understand our own Dutch society. Leiden researchers explore the languages, cultures, religions, legal systems and history of Muslim societies and in this way contribute to a centuries-old tradition.

Live or let die: the intracellular fate of pathogenic mycobacteria
How do mycobacteria subvert the defenses of host immune cells?

Neanderthals could tolerate smoke
The idea that modern humans displaced Neanderthals because they were better protected against toxic smoke components is now under fire. An earlier study that put forward this suggestion has now been refuted by genetic research by scientists from Leiden and Wageningen. This new research was published…

New light on innate plant immunity
Plants are able to resist a pathogen’s attack by a dual innate immune system. The relationship between the two pathways was not clear, but it turns out that they mutually potentiate each other, as assistant professor Pingtao Ding (Institute of Biology Leiden) and colleagues (The Sainsbury Laboratory,…

Single cell technologies for mechanobiology and mechanopharmacology
Mechanobiology is a major area in biology, however, mechanics is currently a missing element in drug development pipelines. This has led to a high cost for the society. Mechanotoxicity of drugs often appears as a long-term side effect of drugs, and has led to removal of drugs from the market. Furthermore,…

Transcutaneous vaccination by means of coated and hollow microneedles
Transcutaneous vaccination is attractive because it is non- or minimally invasive, pain free and the site of administration (skin) is easily accessible. What’s more, transcutaneous immunization can lead to a strong immune response owing to the presence of immune-competent cells in the skin.

Development of cross-protective influenza A vaccines based on cellular responses
Seasonal influenza vaccines provide protection against matching influenza A virus (IAV) strains mainly through the induction of neutralizing serum IgG antibodies. However, these antibodies fail to confer a protective effect against mismatched IAV. This lack of efficacy against heterologous influenza…
