Cancer is still one of the most common diseases in the world. What exactly is cancer and will we one day be able to cure everyone? In a video from the Universiteit van Nederland Noel de Miranda (Tumour Immunology, LUMC) tells you about his research on new treatments.

Ewa Snaar-Jagalska, Shuning He and colleagues from IBL, LION and LACDR reported on a new zebrafish study to understand micrometastasis of human cancer cells. They discovered a novel role for neutrophils in assisting metastasis formation, which provides critical insights for anti-cancer therapies.

This thesis focuses on the application of lipid-based nanomedicine in drug delivery, including small molecular antitumor drugs and biomacromolecules including mRNA, and evaluates their biological performance.

Discovering effective new drugs is a long, expensive and uncertain process. Laura Heitman wants to improve this by finding out more about how drugs bind to proteins that play a role in disease. She calls it ‘drug discovery 3.0’. Inaugural lecture on 9 December.

Within this thesis the central stage is taken by the discovery and investigation of transglycosylation of sterols. First, investigation focuses on the development of a method to accurately detect and quantify glucosylated metabolites in biological materials.

Although rarely considered by the pharmaceutical industry or clinicians, 24-hour rhythms in physiology are a factor of potential influence on the pharmacokinetics and pharmacodynamics of drugs.

Another research line is the development of a spatial CNS drug distribution model, by ultimately including the 3-dimensional anatomical organization of the CNS.

Leiden PhD student Xuequan Zhou has designed a new promising molecule that efficiently kills cancer cells, but does not harm healthy tissue. The trick: the drug is only active when irradiated with light. Zhou’s new compound does this extra efficiently by cleverly self-organising into nanoparticles.…

How can we extend the drug residence time to combat diseases more effectively?

Nature Reviews Drug Discovery volume 18, pages 82–84 (2019). The implications of target saturation for the use of drug–target residence time Wilbert de Witte, Meindert Danhof, Piet van der Graaf, and Elizabeth de Lange

Robert Ietswaart does research into gene regulation at the famous Harvard Medical School in Boston. He developed an algorithm to better predict whether a candidate medicine is going to produce side effects. He studied mathematics and physics in Leiden, and gained his PhD in computational biology in…

Since the start of the Green Office, several projects have been initiated to increase awareness amongst staff & students and to make the university more sustainable. Read all about our current projects here.

Can effective synergists be identified to enhance the effect of antibiotics against Gram negative pathogens?

Uncover novel antimicrobials with prospective health benefits for sea turtles.

The immune system plays a paradoxical role in the spread of breast cancer. Some immune cells contribute to metastasis, while other cells can be activated to strengthen the effect of chemotherapy. Kelly Kersten made this discovery in her PhD research. PhD defence 7 February.

How can you ensure that more experimental drugs reach the finish line? At the moment, only one in twenty cancer drugs that are tested on humans makes it to the market. This is an enormous loss for patients and society. With a grant from the National Growth Fund, Oncode-PACT aims to efficiently select…

Winning a prestigious award for PhD researchers, even before you have your doctorate: that's what Yascha van den Berg managed to do with his research proposal on alternatively spliced tissue factor, a protein that may be involved in tumour growth. Van den Berg: ‘It all started as a Friday afternoon…

In breast cancer, metastasis rather than the primary tumour is the cause of death. A lack of oxygen in the tumour cells promotes this metastasis, accompanied by a reprogramming of the cell's metabolism. PhD candidate Qiuyu Liu investigated these alterations to get more knowledge about the actionable…

Biological chemist Nathaniel Martin and his team received an NWO grant to examine how blocking a specific enzyme in our body, NNMT, could be helpful in the treatment of some cancers. Trials with mice have been promising, and together with the Netherlands Cancer Institute, Martin wants to take the next…

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

The GMP Facility facilitates development and production of Advanced Therapy Medicinal Products (ATMPs) and chemical (peptide) synthesis.

This project develops a scientific method to extract clinically relevant new information from patient forum websites that discuss patient experiences concerning e.g. medication, nutrition, co-morbidities, genetic factors etc.

Leiden researchers have developed a groundbreaking model to advance cancer immunotherapy. Using a 3D printer, they create mini-tumors within an environment that closely mimics human tissue. They have also developed a method to monitor real-time interactions of these mini-tumours with immune cells during…

Roll your sustainable sleeves! Our students and staff have found various ways to do just that, both at home and at our university.

In the search for new medicines against diseases such as cancer, a Leiden team has developed a new workflow. This approach combines artificial intelligence (AI) with molecular modelling and is suitable for finding unknown and innovative drug structures, the researchers proved.

We already know a lot about genetics and the risk of breast cancer. But much still needs to be done in breast cancer genetics to improve the prognosis and make sure women at high risk aren’t missed. This is what Professor by Special Appointment Marjanka Schmidt will say in her inaugural lecture on 4…

When internist Christian Blank made his very first discovery, his field of immunotherapy was the underdog of cancer research. Now, over 20 years later, Blank has been appointed Professor By Special Appointment of Internal Medicine for his clinical research into immunotherapy and will give his inaugural…

Researchers from Leiden University Medical Center (LUMC) and Netherlands Cancer Institute (NKI) have discovered how specialised immune cells can detect and remove cancers that are ‘invisible’ to the conventional defence mechanisms of the immune system. Their work has been published in Nature. The findings…
