Oxidation is a common degradation pathway that affects therapeutic proteins and peptides during production, purification, formulation, transportation, storage and handling of solid and liquid preparations. In the present work we review the scientific literature about structural and biological consequences…

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

The main subject of this thesis is the design and synthesis of paramagnetic molecules for protein studies with NMR and EPR spectroscopy.

SMR can be used to measure the mass of adsorbed protein to nanoparticles with a high precision in the presence of free protein.

Researchers led by Professor of Chemistry Marcellus Ubbink have recently published a study in Proceedings of the National Academy of Sciences (PNAS) about the dynamics of an important redox enzyme. This work was accomplished thanks to an NWO VICI subsidy granted to Professor Ubbink.

Alireza Mashaghi and his research team have created a new framework to understand shapes of proteins and DNA. With this framework, many diseases can be understood better.

Chemist Gerjan de Bruin has designed a method of slowing down the degradation process of proteins in cells. This may contribute to new cancer medicines with fewer side-effects. PhD defence on 1 June.

The team of Alireza Mashaghi at the Leiden Academic Centre for Drug Research has found a way to determine and classify the shape of proteins. Their new theory defines the topology of proteins as a simple and precise barcode that allows the identification of all types of folds. ‘This barcode enables…

Research groups in the Biological & Soft Matter Programme unravel mechanisms in biological processes and develop novel bio-inspired soft materials.

Leiden University has appointed John van Noort as Professor in Biophysics. He studies the way in which our DNA is folded and read out.

By measuring proteins in tears, ophthalmologists can more easily diagnose dry eyes (Dry Eye Disease). Peter Raus, a Belgian ophthalmologist and PhD student at the Institute of Biology Leiden, developed a new method for protein determination in tear fluid. The technique is also promising for the early…

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…

Some bacteria, it turns out, have proteins much like ours that organise the DNA in their cells. They just do it a bit differently. This is revealed by new research from biochemists at the Leiden Institute of Chemistry and the Max Planck Institute for Biology. The discovery helps us better understand…

Chemical biologists from Leiden, led by Dr Mario van der Stelt, have discovered substances that can reduce inflammation processes in the brain. This is a first step in the development of potential medicines for the treatment of brain diseases like Alzheimer's and Parkinson's. Published in Proceedings…

Martina Huber, Jacqueline Labra Munoz research Alzheimer's disease. They study ferritine, iron storage in the brain. An inbalance of iron could play a role in this form of dementia.

Two Leiden astronomers will receive the prestigious IAU PhD Prize. Both Jorryt Mathee and Niels Ligterink of the Leiden Observatory won a prize. Scientific director Huub Röttgering: We are proud that this year two of our PhD students receive an IAU prize for the best thesis in their field of researc…
