Preclinical and clinical evidence suggests that neuropeptides play a role in the pathophysiology of mood disorders. In the present study, we investigated the involvement of the peptides corticotropin-releasing hormone (CRH), neuropeptide Y (NPY) and nociceptin/orphanin FQ (N/OFQ) and of their receptors in the regulation of emotional behaviours. In situ(More)
The basolateral nucleus of the amygdala (BLA) plays a key role in emotional arousal and anxiety, and expresses high levels of corticotropin-releasing factor receptor (CRFR)1. In rat brain slices, we have recently shown that afferent activation of the BLA is increased following application of exogenous corticotropin-releasing factor (CRF). Here we examined(More)
Chronic treatment with cannabinoid agonists leads to tolerance. One possible mechanism for this is receptor internalization, but tolerance has also been reported with compounds that only cause internalization to a low degree. Furthermore, cannabinoid antagonist administration precipitates a characteristic withdrawal syndrome in tolerant subjects,(More)
A novel series of trans-8-aminomethyl-1-oxa-3-azaspiro[4.5]decan-2-one derivatives was identified with potent NPY Y5 antagonist activity. Optimization of the original lead furnished compounds 23p and 23u, which combine sub-nanomolar Y5 activity with metabolic stability, oral bioavailability, brain penetration and strong preclinical profile for development.(More)
The involvement of Neuropeptide Y (NPY) in the pathophysiology of mood disorders has been suggested by clinical and preclinical evidence. NPY Y1 and Y2 receptors have been proposed to mediate the NPY modulation of stress responses and anxiety related behaviors. To further investigate the role of Y2 receptors in anxiety we studied the effect of BIIE0246, a(More)
Substance P exerts its various biochemical effects mainly via interactions through neurokinin-1 receptors (NK1). Recently, the NK1 receptor has attracted considerable interest for its possible role in a variety of psychiatric disorders including depression and anxiety. However, little is known regarding the anatomical distribution of NK1 in the human(More)
As people age they become increasingly susceptible to chronic and extremely debilitating brain diseases. The precise cause of the neuronal degeneration underlying these disorders, and indeed normal brain ageing remains however elusive. Considering the limits of existing preventive methods, there is a desire to develop effective and safe strategies. Growing(More)
Identifying accurate biomarkers of cognitive decline is essential for advancing early diagnosis and prevention therapies in Alzheimer's disease. The Alzheimer's disease DREAM Challenge was designed as a computational crowdsourced project to benchmark the current state-of-the-art in predicting cognitive outcomes in Alzheimer's disease based on high(More)
It has been hypothesized that the neuropeptide Y (NPY) system is involved in the pathogenesis of mood disorder. In this study, Y1 and Y2 receptor mRNA expression levels were analyzed in the dorsolateral prefrontal cortex of subjects affected with major depression, bipolar disorder, or schizophrenia and compared to normal controls. No significant alterations(More)
