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.

'It gave our team a big boost to hear that our work was valuable,' says medical chemist Elmer Maurits about the moment they won the Venture Challenge. With their company Iprotics, they want to develop a drug that can better treat patients with autoimmune diseases and blood cancers. 25,000 euros of prize…

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…

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…

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…

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…

Leiden biophysicist Stefano Coppola has received the prestigious AXA Research Fund postdoctoral fellowship. With this grant he can work for two years on a project to research the role of mechanical factors in the development of pancreatic cancer.
