Imaging the density of metabotropic glutamate receptor 5 (mGluR5) in brain by positron emission tomography (PET) is of interest in relation to several brain disorders. We have recently introduced [(18) F]PSS232, an F-18-labeled analog of the mGluR5-targeting [(11) C]ABP688. Quantitative PET requires kinetic modeling with an input function (IF) or an(More)
The cannabinoid receptor type 2 (CB2) is part of the endocannabinoid system and has gained growing attention in recent years because of its important role in neuroinflammatory/neurodegenerative diseases. Recently, we reported on a carbon-11 labeled 4-oxo-quinoline derivative, designated RS-016, as a promising radiotracer for imaging CB2 using PET. In this(More)
Serotonin-gated ionotropic 5-HT3 receptors are the major pharmacological targets for antiemetic compounds. Furthermore, they have become a focus for the treatment of irritable bowel syndrome (IBS) and there is some evidence that pharmacological modulation of 5-HT3 receptors might alleviate symptoms of other neurological disorders. Highly selective,(More)
BACKGROUND The inflammatory nature of atherosclerosis provides a broad range of potential molecular targets for atherosclerosis imaging. Growing interest is focused on targets related to plaque vulnerability such as the co-stimulatory molecules CD80 and CD86. We investigated in this preclinical proof-of-concept study the applicability of the(More)
Research towards the non-invasive imaging of atherosclerotic plaques is of high clinical priority as early recognition of vulnerable plaques may reduce the incidence of cardiovascular events. The fibroblast activation protein alpha (FAP) was recently proposed as inflammation-induced protease involved in the process of plaque vulnerability. In this study,(More)
Classical benzodiazepines, which are widely used as sedatives, anxiolytics and anticonvulsants, exert their therapeutic effects through interactions with heteropentameric GABAA receptors composed of two α, two β and one γ2 subunit. Their high affinity binding site is located at the interface between the γ2 and the adjacent α subunit. The α-subunit gene(More)
Over the past two decades, our understanding of the endocannabinoid system has greatly improved due to the wealth of results obtained from exploratory studies. Currently, two cannabinoid receptor subtypes have been well-characterized. The cannabinoid receptor type 1 (CB1) is widely expressed in the central nervous system, while the levels of the cannabinoid(More)
