Making the invisible visible with ‘click chemistry’
Sander van Kasteren (Professor of Molecular Immunology) makes the invisible visible. He will explain more in his inaugural lecture.

The career choices of cells
How does an embryonic stem cell decide if it becomes a heart cell or a kidney cell? That’s the question computational biologist Maria Mircea studied for her PhD research. She looked at the inside of individual cells to analyse how they change. This is what she discovered.

How bittersweet sugar chemistry targets pathogens
The challenge is considerable, but so is the satisfaction when it succeeds: creating complex sugar molecules that play a role in biology.

Bacteria without cell wall gobble up DNA from environment
A bacterium hiding from the immune system and picking up bits of DNA from its environment. The result: gaining new traits, such as better protection against antibiotics. Fortunately, we have not found such a damning scenario yet. However, PhD student Renée Kapteijn did find the first clues, which…

How cells talk by pulling on a fibre network
Mechanics play a larger role in blood vessel formation, and other developmental biology, than previously thought. Cells appear to respond to mechanical signals, such as pressure. Through the extracellular matrix, a network of fibrous proteins, cells can supposedly exchange those mechanical signals over…

300 million euros for new international stem cell consortium
The Leiden University Medical Center (LUMC), the Danstem Institute from the University of Copenhagen and the Murdoch Children’s Research Institute in Melbourne have received 300m euros from the Novo Nordisk foundation. The aim of this new international consortium is to bring stem-cell based therapies…

Modified caffeine molecules help medical research move forward
Before researchers can develop targeted drugs, they need to know exactly how a disease works. Biochemist Bert Beerkens created molecules that allow them to find out. He used caffeine as the basis for new molecules that enable research into certain receptor proteins on cells.

Helping students with micro-macro thinking in chemistry
How do classroom demonstration experiments help students learn chemical reasoning? Marie-Jetta den Otter, PhD student at ICLON, researched this. She defends her thesis on 6 December.

How to hijack natural destruction in cells: ‘We need to understand it through and through’
Destroying proteins from the Golgi apparatus of the cell in a controlled manner. That is the focus of chemist Marta Artola’s pioneering research. By developing a groundbreaking technology to target specific proteins in the Golgi, Artola aims to unlock new ways for drug development. For this ambitious…

The Nobel Prize in Chemistry went to an AI model (and rightly so)
Not experiments and lab coats, but computers and artificial intelligence: this year's Nobel Prize in Chemistry went to the inventors of the groundbreaking AI model, AlphaFold. This programme accurately predicts protein structures based on their genetic code—a crucial step in understanding biological…

How cells determine the fate of proteins (and can we do it too?)
Cells in our bodies are often threatened by errors in our own proteins. The FLOW consortium, comprising scientists from various institutions including Leiden, is poised to meticulously map out for the first time how cells control proteins, correcting or removing faulty ones. This endeavour holds promise…

Young, sleeping memory cells are crucial in fighting a reinfection
Researchers from the Netherlands Cancer Institute, the Leiden University Medical Center (LUMC) and Oncode have created a tracking system that can reveal how often cells have divided. This allowed them to find a yet undiscovered population of immune cells: young memory cells that behave like stem cells.…

Sander van Kasteren: from molecule builder to Professor of Chemical Immunology
Sander van Kasteren only noticed some small, subtle changes since he was appointed professor on 1 May. Still, he has to get used to the idea, even though he had been working towards the professorship for a few years. ‘I don't quite see myself as a professor yet.'

forming embryo to cancer metastasis: the significance of collective cell movement
Luca Giomi has the first results of his ERC consolidator grant. He discovered that epithelial cells move collectively but in different ways, depending on the scale you look at. It is hexatic at small scales, and becomes nematic at larger scales: it is a multiscale order. This collective movement of…

Tunnel vision alarm in the search for more efficient hydrogen cells
A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

Leiden chemists discover new ways in which single-celled organisms organise their DNA
It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden PhD candidate Samuel Schwab has found that the histones in these organisms are much more diverse than previously thought. Schwab and his colleagues describe…

Inexhaustible source of human heart muscle cells allows strong reduction of animal testing
Researchers at the Leiden University Medical Centre (LUMC) have managed to culture human heart muscle cells on a massive scale. This is an exceptional achievement because it is very difficult to replicate heart muscle cells outside the body. Using a special technique, the researchers have now created…
