Inactivating mutations in BRCA1 or BRCA2 genes predispose to several types of cancer.

Diacylglycerol lipases (DAGLα and DAGLβ) convert diacylglycerol to the endocannabinoid 2-arachidonoylglycerol. Our understanding of DAGL function has been hindered by a lack of chemical probes that can perturb these enzymes in vivo.

CONCLUSION: This study demonstrates that human macrophages can be induced to exert direct anti-tumor activity against osteosarcoma cells. Our observation that the induction of macrophage anti-tumor activity by L-MTP-PE required IFN-gamma may be of relevance for the optimization of L-MTP-PE therapy in…

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…

Inhibiting specific protein production in the human body can serve as a crucial weapon in the fight against Alzheimer's, Eline van Maanen believes. PhD defence 23 November.

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

Proteases degrade matrix molecules in the atherosclerotic plaque, thereby reducing atherosclerotic plaque stability. Mast cells, that contain proteases such as tryptase and chymase, have been identified at the site of rupture in specimens of human coronary arteries and their number in the plaque was…

Atherosclerosis is a chronic inflammatory disease, and vaccination may be an attractive method to induce long lasting protection against endogenous factors that contribute to the development of atherosclerosis. We have shown that for example vaccination against modified LDL or interleukin-12 limits…

This thesis explores different avenues to develop insurmountable antagonists for CC Chemokine Receptors, such as CCR1, CCR2 and CCR5.

The Aging and Immunity group is led by Dr. Amanda Foks. In this group we aim to investigate how aged immune cells contribute to atherosclerosis and identify novel therapeutic targets and strategies to extend health span and inhibit cardiovascular disease.

The drug BIA 10-2474 inhibits fatty acid amide hydrolase (FAAH), a lipase that degrades a specific endocannabinoid. On the basis of this activity, BIA 10-2474 was being developed as a potential treatment for anxiety and pain. In a phase 1 trial of the drug, one subject died, and four others suffered…

According to the amyloid cascade hypothesis, accumulation of beta-amyloid (Aβ) peptides initiates the pathological cascade in Alzheimer's disease (AD).

India’s prime minister Narendra Modi admires Israel’s achievements, but structural differences between Indian and Israeli national security situations, differences in the leaders’ worldviews and the absence of a common enemy inhibits stronger strategic rapprochement, argues political scientist Nicolas…

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

Dr. Foks obtained this fellowship for the project “Can promotion of efferocytosis induce regression of atherosclerosis?”, in which she aims to identify novel targets to promote regression of atherosclerosis. This research grant allows her to initiate independent research for the next three years.

How can we find novel natural products from Actinomycetes that act as growth modulators on mammalian cells? Can we harvest and develop the potential of these novel compounds for industrial and medical biotechnology?

Intergenerational transmission refers to the complex and dynamic process with which values, ideas and behaviors are transmitted across generations. We are specifically interested in the intergenerational transmission of behaviors and beliefs that might result in harm to the individuals involved or society…
