What are the host immune defence mechanisms that control intracellular infections and how are these subverted by pathogens?

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…

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…

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,…

Control of infectious diseases poses continuous challenges for human health.

Unraveling the immune-suppressive actions of drugs like prednisone.

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.

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.

Worldwide resurgence of pertussis necessitates the need for improvement of pertussis vaccines and vaccination strategies.

How are carbohydrates processed by the immune system? Can carbohydrates be used to trigger T-cells against other conjugated antigens? Can they be used as adjuvants?

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

How can zebrafish research help understanding human diseases?

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

How can Staphylococcus aureus bacteria subvert the host immune system?

Traditionally, vaccines are administered intramuscularly using conventional hypodermic needles, which cause pain and distress. Microneedles are very short needles (smaller than 1 mm) that are practically invisible to the naked eye.

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

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…

The Aging and Immunity group is led by Dr. Amanda Foks. In this group we aim to investigate how aged immune cells contribute to atherosclerosis and identify novel therapeutic targets and strategies to extend health span and inhibit cardiovascular disease.

The Immune Activation and Tolerance group is headed by Dr. Bram Slütter. Vaccination is an experimental, but promising, treatment strategy for atherosclerosis. Previous work has shown that immunization of mice with modified LDL particles can reduce atherosclerotic lesion development, however such vaccines…

Which immune mechanisms are involved in host defense against Staphylococcal infection?

How do mycobacteria subvert the defenses of host immune cells?

One of the main challenges in the development of an effective anti-cancer vaccine is the generation of an adequate and directed cellular immune response.

Can we enhance the capacity of host immune cells to kill mycobacteria via production of reactive nitrogen species?

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

Glucocorticoids (GCs) are widely prescribed as anti-inflammatory drugs due to their well-established immunosuppressive effects.

In this research project, we aimed to obtain more insight in the role of mast cells in the immune driven disorders rheumatoid arthritis and atherosclerosis.

Effective host defence against tuberculosis bacteria depends on a properly balanced level of inflammation. The Inflammafish project uses zebrafish larvae to study how autophagy controls this inflammation and vice versa.

To what extent and in what manner can experimental video be used to reclaim the capacity for telling one’s own story, on one's own terms, speaking in tongues outside the linguistic framework of immune system discourse?

In the hunt for a vaccine against cervical cancer, fundamental knowledge about the immune system and organic chemistry have been brought together and have already resulted in a vaccine that is now being tested in clinical trials. Scientists are now working hard on an improved variant.

In autoimmune diseases such as rheumatism and diabetes the immune system attacks autologous proteins. Leiden researchers are trying to discover how this comes about.
