G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

The objective of this project is to fundamentally improve our understanding of the ways in which science progresses. Empirical studies have used bibliographic metadata to provide relevant insights, but these studies have failed to tell us how science progresses. Supported by computational advances and…

Traditional drug discovery approaches have been hampered by (in vitro) cell-culture models that poorly represent the situation in the human body.

The disease acute myeloid leukemia (AML) is characterized by fast progression and low survival rates.

The advanced insights obtained for the CNS PBPK model development are currently used to develop advanced mathematical models for drug distribution prediction in other body tissues protected by barriers, such as the gut. The gut PBPK model will be linked to drug effects for treatment of colon cancer.

In order to be able to develop effective medicine and treatments to prevent or cure autoimmune diseases or cancer we need to understand the mechanisms how they arise and what drives their course.Unravelling the fundamental molecular mechanisms influencing the onset and course of diseases such as allergies,…

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…

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.

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.…

Cancer is one of the main causes of death in the Netherlands. Leiden researchers are working to improve the treatment of different types of cancer in order to increase the patient’s quality of life. A better understanding of how cancer develops will make it possible to deliver personalised and precise…

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.

As of April 1, 2018, Erik Danen has been appointed as Professor of Cancer drug target discovery at the Leiden Academic Centre for Drug Research (LACDR). His discipline is cell biology of cancer, in which he focuses on the mechanisms underlying metastasis and therapy resistance.

Ariane Briegel wants to use bacteria to detect cancer at an early stage. Together with postdoc Alise Muok, she is developing a method to quickly and cheaply test the urine of patients for the presence of suspicious molecules. They receive a grant of approximately 150,000 euros from the Dutch Cancer…

With a Vici grant of 1.5 million euros, Professor of Mathematical biology Roeland Merks will look for ways to fix messy and leaky blood vessels in tumours. His research combines mathematical simulations and lab experiments in a unique way.

Leiden University Medical Center (LUMC) has spent the past five years coordinating an international study of genetic mutations and breast cancer risks. The results will make it easier to determine which genes increase the risk of breast cancer and to what extent. The researchers published their results…

We are interested in the efficacy and safety of new drugs and novel means to decipher these aspects. Hence, we employ advanced imaging and high-throughput screening techniques next to computational approaches such as chem- and bioinformatics.

To inhibit proteins that contribute to the growth of aggressive cancer cells, that’s the plan of Professor Bob van de Water and his team. They will receive over 700,000 euros from the KWF Dutch Cancer Society for their research. Researcher Maaike Vreeswijk and pathologist Danielle Cohen are affiliated…

On the 22nd of February, Ami Okabe successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Ami on this achievement!

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…

A therapeutic vaccine against HPV-16 (type 16 human papillomavirus) improves the survival rate in cervical cancer patients. A new study by ISA Pharmaceuticals B.V.
