African worm infections and innovative thermometers have shown Leiden researchers how to fight diseases of affluence and keep health…

How can zebrafish research help understanding human diseases?

Lecture

This project is part of the Next Generation ImmunoDermatology (NGID) consortium, which focuses on the comprehensive phenotyping of six different immune-mediated inflammatory skin conditions. A common factor contributing to these diseases is a dysfunctional skin barrier. The skin barrier function is…

The predication of the effect (efficiency and toxicity) of a drug in a patient is very important in (i) clinical decision support and (ii) the development of novel drug treatments.

We aim to understand ion homeostasis in the model eukaryote S. cerevisiae.

Plant biologist Pingtao Ding, assistant professor at the Institute of Biology Leiden (IBL), has received a 2.4 million European grant from the European Research Council (ERC). This ERC Starting Grant for promising young researchers allows him to unravel the molecular mechanisms by which plants resist…

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?

Identifying novel antibiotic compounds to tackle antibiotic-resistant bacteria. Researchers from Leiden University and VU Amsterdam will unite through a project now funded by NWO’s Open Technology Programme (OTP), which awarded the collaboration nearly one million euros.

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

The word ¨pyroptosis¨ can be understood as ¨fiery falling¨, which describes the bursting of pro-inflammatory signals from the dying cell. Our observations indicate that pyroptosis also ¨spreads like wildfire¨ and once a cell dies via pyroptotic cell death, neighbouring cells are more prone to die as…

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.

About one and a half million people worldwide die each year from tuberculosis. For thirty years, therapy with antibiotics has been the same, while it takes far too long and can lead to resistant pathogens. Leiden researchers from four institutes are now joining forces to develop more effective and efficient…

Professor of Ultrastructural Biology Ariane Briegel has received a grant in the NWO Open Competition Domain Science in the XS category. This grant emphatically encourages curiosity-driven and bold research with a maximum of 50,000 euros.

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

Overkleeft

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.

Using artificial intelligence to find new antibiotics. With that, researchers from Leiden University are nominated by magazine KIJK for the Best Tech-idea of 2021. From September 14 onwards people can vote to crown one of the nominees as the winner.

Prediction of human (CNS) target site concentrations in health and disease In the vision of Prof. de Lange we will only be able to predict human (central nervous system, CNS) target site concentrations and effects if we perform systematic, condition-dependent, integrative, and strictly quantitative…

The opportunity to explore a new, exciting research topic. That is how Lennart Schada von Borzyskowski describes his successful application for the NWO XS grant. It comprises 50,000 euros, which the researcher from the Institute of Biology Leiden (IBL) will spend on investigating a more sustainable…

Why do some bacteria lose their protective cell wall under the influence of stress? Microbiologist Dennis Claessen of the Institute of Biology Leiden receives a Vici grant of 1.5 million euros from the Dutch Research Council (NWO) to investigate this paradoxical feature.

How can Staphylococcus aureus bacteria subvert the host immune system?

Leiden biologists have shown that a gene present in plants, animals and yeasts does play an important role in plants, although for years the gene was considered unimportant. It turns out the gene plays a crucial role in the development of vascular tissue in plants. Publication in Nature Plants on 11…

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

Harvesting rice from the same field, without planting new rice plants? A discovery may bring this scenario closer. Leiden scientists have discovered a gene that allows annual plants to grow after flowering, instead of dying. Publication on 13 April in Nature Plants.

How do mycobacteria subvert the defenses of host immune cells?

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

Producing offspring of a crop without sowing and that is even bigger than the parent plant. According to Leiden researchers this can be achieved by overstimulating a single gene that rejuvenates cells, including bringing them back to the embryonic phase.

Advanced mass spectrometry of glycosphingolipids takes the central stage in this thesis. Investigations focus on characterization of glycosphingolipid metabolism in health and disease with emphasis to the detection and accurate quantitation of known and so far unknown glycosphingolipids and closely…

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.

Researchers at Leiden University have made a breakthrough in the study of the hereditary Pompe disease. Together with colleagues in York, they have developed a molecule that binds to the enzyme that is key to the progress of the disease. The findings have been published in ACS Central Science.

Can we exploit the cell death machinery of the host to develop new host-directed anti-TB treatments?

Promotores: H.A. Udo De Haes, P.M. Brakefield

How is Pol θ responsible for T-DNA integration, and how do other DNA double-strand break repair pathways interact with Pol θ? How may we manipulate T-DNA integration to stimulate error-free integration at a predetermined genomic site?

Is translocation of nucleases possible via Agrobacterium T4SS and is it efficient enough for mutagenesis?

Can drug screening for tuberculosis treatment be made more efficient?

In April, the X-omics initiative was granted 17 million euros from the Dutch Organization for Scientific Research. The subsidy is part of the National Roadmap for large-scale scientific infrastructure, intended to build or renew large-scale research facilities. What new insights will this investment…

The central question of this Vici proposal is to investigate if, and how actinobacteria exploit life without a cell wall.
