Translational Evaluation of JNJ-18038683, a 5-Hydroxytryptamine Type 7 Receptor Antagonist, on Rapid Eye Movement Sleep and in Major Depressive Disorder
TLDR
JNJ-18038683 enhanced serotonin transmission, antidepressant-like behavior, and REM sleep suppression induced by citalopram in rodents and in healthy human volunteers, demonstrating that the effect of 5-HT7 blockade on REM sleep translated from rodents to humans. Expand
Pharmacological Characterization of JNJ-40068782, a New Potent, Selective, and Systemically Active Positive Allosteric Modulator of the mGlu2 Receptor and Its Radioligand [3H]JNJ-40068782
TLDR
The present data demonstrate that JNJ-40068782 has utility in investigating the potential of mGlu2 modulation for the treatment of diseases characterized by disturbed glutamatergic signaling and highlight the value of [3H]JNJ- 40068782 in exploring allosteric binding. Expand
Blocking melanin-concentrating hormone MCH1 receptor affects rat sleep-wake architecture.
TLDR
Therapeutic application of melanin-concentrating hormone MCH(1) receptor-inhibiting agents should take into account the significant decreases in deep sleep without recovery as these may interfere with sleep dependent memory consolidation. Expand
Modulation of group II metabotropic glutamate receptor (mGlu2) elicits common changes in rat and mice sleep-wake architecture.
TLDR
Findings show common changes ofREM sleep variables following modulation of metabotropic glutamate mGlu(2) receptor and support an active role of this receptor in the regulation of REM sleep. Expand
Discovery of 3-cyclopropylmethyl-7-(4-phenylpiperidin-1-yl)-8-trifluoromethyl[1,2,4]triazolo[4,3-a]pyridine (JNJ-42153605): a positive allosteric modulator of the metabotropic glutamate 2 receptor.
TLDR
Advanced leads from a series of 1,2,4-triazolo[4,3-a]pyridines with mGlu2 receptor PAM activity are reported, with a central in vivo efficacy by inhibition of REM sleep state at a dose of 3 mg/kg po in the rat sleep-wake EEG paradigm. Expand
How to Keep the Brain Awake? The Complex Molecular Pharmacogenetics of Wake Promotion
TLDR
The correlation between specific EEG and gene-expression signatures suggests that the neuronal pathways activated to stay awake vary among drugs and genetic background. Expand
Emergence of early alterations in network oscillations and functional connectivity in a tau seeding mouse model of Alzheimer’s disease pathology
TLDR
The induction of intracellular tau aggregation by tau seed injection results in early altered connectivity and strong theta–gamma oscillations uncoupling, which may be exploited as an early electrophysiological signature of dysfunctional neuronal networks. Expand
Sleep and EEG patterns in the chronic constriction injury model of neuropathic pain
TLDR
It is concluded that in the chronic phase, this neuropathic pain model does not produce clear sleep disturbances, and an absence of general suffering from sleep disturbances is advantageous to the CCI model as it makes use of the model more acceptable ethically. Expand
Relevance of the metabotropic glutamate receptor (mGluR5) in the regulation of NREM-REM sleep cycle and homeostasis: Evidence from mGluR5 (−/−) mice
TLDR
The findings strongly indicate that mGluR5 is involved in shaping the stability of NREM sleep-REM sleep state transitions, NREM slow wave activity and homeostatic response to sleep loss. Expand
Discovery of VU0409551/JNJ-46778212: An mGlu5 Positive Allosteric Modulator Clinical Candidate Targeting Schizophrenia.
Herein, we report the structure-activity relationship of a novel series of (2(phenoxymethyl)-6,7-dihydrooxazolo[5,4-c]pyridine-5(4H)-yl(aryl)methanones as potent, selective, and orally bioavailableExpand
