On 23 April 2021, Professor Alfred Vertegaal from the Department of Cell and Chemical Biology at the Leiden University Medical Center (LUMC) delivered his inaugural lecture ‘Unraveling and exploiting cellular communication codes’. Vertegaal used the opportunity to describe how research in the field…

The transition from single cells to multicellular organisms was a key step in evolution. Researchers from Leiden and Amsterdam developed a mathematical model that explains how this transition may have come about. They suspect cooperating cells may correct each other’s mistakes. Publication in eLife…

Leiden University Medical Center (LUMC), as a partner in the reNEW consortium, is once again receiving tens of millions of euros for research into new treatments based on stem cells. The collaboration will receive a total of €150 million to develop new therapies in regenerative medicine.

Researchers from the Leiden University Medical Center (LUMC) have successfully used stem cell gene therapy to treat a baby with the severe congenital immune disorder SCID. An important milestone: it is the first time stem cell gene therapy of Dutch origin has been administered to a patient, and also…

Leiden and Austrian researchers have succeeded in further uncovering how a plant cell passes on the growth hormone auxin in a directional manner to the next cell. Three proteins that cling together in a bunch appear to be essential for this important transport process. ‘This discovery solves a crucial…

Researchers from the Leiden Institute of Chemistry show proof of principle that live-cell structural changes and metabolic processes can be followed in real time with NMR spectroscopy. They performed their study on photosynthetic green algae that are metabolically flexible and can sustain energy generation…

How can we prevent drug-induced liver and kidney damage? PhD candidates Marije Niemeijer and Lukas Wijaya investigated what happens in the cells during the onset of this damage: a stress response. Both focused on a different subtopic and made some interesting discoveries.

A more efficient solar panel sounds great. But what if these new panels consume more toxic materials, or their production consumes a lot of energy? Leiden environmental scientists, together with colleagues from the Fraunhofer ISE, address this multifaceted question in a new publication in the prestigious…

We aim to provide new insights relating to the spectacular multi-cellular life cycle of streptomycetes and other actinobacteria.

Parkinson's disease is the second most common neurodegenerative disease in the world. One of its symptoms is the loss of dopaminergic neurons in the substantia nigra pars compacta.

Can furan-based resisn be degraded by microbial enzymes in combination with mild pre-treatment?

Healthy aging is one of the prime goals in today's society and atherosclerosis is among the greatest causes of morbidity in elderly. Cardiovascular disease patients receiving treatment are often of advanced aged and have an aged immune system, which limits translating experimental findings to the pa…

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

Reducing greenhouse gas emissions is one of the most pressing challenges that humanity faces in the coming decades.

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…

Traditional biochemical methods for studying organelles require cell disruption, preventing the real-time observation of dynamic intracellular processes.

In summary, the collective results described in this thesis show that nanoparticulate vaccines can be delivered intradermally by coated and hollow microneedles and evoke antigen-specific immune responses.

In the research programme Microbial Sciences we perform state-of-the-art research in the field of biotechnology and microbial sciences.

Bacterial biocatalysis constitutes a sustainable alternative for high-value chemicals production by enabling the utilization of renewable feedstocks.

The human body consists of hundreds, perhaps thousands of different types of cells, each with different morphologies and functions, despite having the same genome.

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

The major and ultimate aim of metabolomics is to obtain an answer to a specific biological or clinical question.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

Leiden biophysicist Stefan Semrau was granted an NWO Vidi earlier this month. He will use the grant to study the role of electricity in embryonic development and tissue regeneration.

‘Regenerative medicine’ explores ways to repair or replace damaged cells, tissues and organs with cell, stem-cell or gene therapy. It can lead to valuable breakthroughs in the treatment of chronic diseases such as diabetes, heart problems and kidney diseases or muscle diseases.

The Cardiovascular Pharmacology research group headed by Ilze Bot aims to elucidate the mechanisms that underlie atherosclerotic plaque destabilization, which is the key process that leads to acute cardiovascular syndromes such as a myocardial infarction or stroke.

Metastasis is responsible for over 90% of cancer-related deaths and arises from the ability of a small subset of tumor cells to detach from the primary tumor, overcome multiple biochemical and mechanical barriers, disseminate through the body, and colonize distant organs.
