Radin , Steven Johnson, Richard Purcell, Arnold S. Lippa RespireRx Pharmaceuticals, Inc., 126 Valley Road, Glen Rock, NJ, 07452, United States ARTICLE INFO ABSTRACT Keywords: Neurotrophin dysregulation has been implicated in a large number of neurodegenerative and neuropsychiatric Ampakine diseases. Unfortunately, neurotrophins cannot cross the blood brain barrier thus, novel means of up regulating BDNF their expression are greatly needed. It has been demonstrated previously that neurotrophins are up regulated in Cognitive enhancement response to increases in brain activity. Therefore, molecules that act as cognitive enhancers may provide a LTP clinical means of up regulating neurotrophin expression. Ampakines are a class of molecules that act as positive Neurotrophin allosteric modulators of AMPA-type glutamate receptors. Currently, they are being developed to prevent opioid- NGF induced respiratory depression without sacrificing the analgesic properties of the opioids. In addition, these molecules increase neuronal activity and have been shown to restore age-related deficits in LTP in aged rats. In the current study, we examined whether two different ampakines could increase levels of BDNF and NGF at doses that are active in behavioral measures of cognition. Results demonstrate that ampakines CX516 and CX691 induce differential increases in neurotrophins across several brain regions. Notable increases in NGF were ob- served in the dentate gyrus and piriform cortex while notable BDNF increases were observed in basolateral and lateral nuclei of the amygdala. -
From Inverse Agonism to 'Paradoxical Pharmacology' Richard A
International Congress Series 1249 (2003) 27-37 From inverse agonism to 'Paradoxical Pharmacology' Richard A. Bond*, Kenda L.J. Evans, Zsirzsanna Callaerts-Vegh Department of Pharmacological and Pharmaceutical Sciences, University of Houston, 521 Science and Research Bldg 2, 4800 Caltioun, Houston, TX 77204-5037, USA Received 16 April 2003; accepted 16 April 2003 Abstract The constitutive or spontaneous activity of G protein-coupled receptors (GPCRs) and compounds acting as inverse agonists is a recent but well-established phenomenon. Dozens of receptor subtypes for numerous neurotransmitters and hormones have been shown to posses this property. However, do to the apparently low percentage of receptors in the spontaneously active state, the physiologic relevance of these findings remains questionable. The possibility that the reciprocal nature of the effects of agonists and inverse agonists may extend to cellular signaling is discussed, and that this may account for the beneficial effects of certain p-adrenoceptor inverse agonists in the treatment of heart failure. © 2003 Elsevier Science B.V. All rights reserved. Keywords. Inverse agonism; GPCR; Paradoxical pharmacology 1. Brief history of inverse agonism at G protein-coupled receptors For approximately three-quarters of a century, ligands that interacted with G protein- coupled receptors (GPCRs) were classified either as agonists or antagonists. Receptors were thought to exist in a single quiescent state that could only induce cellular signaling upon agonist binding to the receptor to produce an activated state of the receptor. In this model, antagonists had no cellular signaling ability on their own, but did bind to the receptor and prevented agonists from being able to bind and activate the receptor. -

China 4Department of Laboratory Medicine, Bengbu Medical College, Bengbu, P.R. China Oligodendrocyte precursor cells (OPCs) are bipotential progenitor cells that can differentiate into myelin-forming oligodendrocytes or functionally undetermined type II astrocytes. Transplantation of OPCs is an attractive therapy for demyelinating diseases. However, due to their bipotential differentiation potential, the majority of OPCs differentiate into astrocytes at transplanted sites. It is therefore important to understand the molecular mechanisms that regulate the transition from OPCs to oligodendrocytes or astrocytes. In this study, we isolated OPCs from the spinal cords of rat embryos (16 days old) and induced them to differentiate into oligodendrocytes or type II astrocytes in the absence or presence of 10% fetal bovine serum, respectively. RNAs were extracted from each cell population and hybridized to GeneChip with 28,700 rat genes. Using the criterion of fold change > 4 in the expression level, we identified 83 genes that were up-regulated and 89 genes that were down-regulated in oligodendrocytes, and 92 genes that were up-regulated and 86 that were down-regulated in type II astrocytes compared with OPCs. -

Misophonia is a sound-sensitivity condition which causes an unusually strong aversion to particular sounds 1. For people with misophonia, sounds like chewing, for example, can cause extreme anger, disgust or even fear 1. Misophonia trigger-sounds are typically human-made, such as eating- noises, throat and nasal sounds, rustling, or tapping2. Misophonia ` typically emerges during childhood or adolescence, and can improve or worsen over time3. Although misophonia is not a disease, it has a known neurological basis4 and is recognised by health bodies such as the NHS (UK National Health Service) and the British Tinnitus Assocaition5.

It was a large scale, online survey with over 1,000 respondents. The key findings were as follows. 1) People suffering with misophonia experience a reduced quality of life. 2) Misophonia can develop at any age, with the median and mode age of onset at 9-10 years. 3) Treatments to date had been generally ineffective, but some reported treatment being very helpful. 4) Eating stimuli are by far the most common, with 96% of people reporting this trigger. 5) Most people reported physical reactions as a part of their response to triggers. 2 Misophonia phenomenology and impact If you are looking for a definition of misophonia, it is a severe sensitivity to specific soft sounds and visual images. It also includes other forms of stimuli that cause an immediate extreme reaction. When a person hears the sounds, the person has a very strong emotional reaction such as hate, anger, anxiety, rage, and resentment. -
Are AMPA Receptor Positive Allosteric Modulators Potential Pharmacotherapeutics for Addiction?

Received: 28 October 2013; in revised form: 13 December 2013 / Accepted: 24 December 2013 / Published: 30 December 2013 Abstract: Positive allosteric modulators (PAMs) of α-amino-3-hydroxy-5-methyl-4- isoxazolepropionic acid (AMPA) receptors are a diverse class of compounds that increase fast excitatory transmission in the brain. AMPA PAMs have been shown to facilitate long-term potentiation, strengthen communication between various cortical and subcortical regions, and some of these compounds increase the production and release of brain-derived neurotrophic factor (BDNF) in an activity-dependent manner. Through these mechanisms, AMPA PAMs have shown promise as broad spectrum pharmacotherapeutics in preclinical and clinical studies for various neurodegenerative and psychiatric disorders. In recent years, a small collection of preclinical animal studies has also shown that AMPA PAMs may have potential as pharmacotherapeutic adjuncts to extinction-based or cue-exposure therapies for the treatment of drug addiction. The present paper will review this preclinical literature, discuss novel data collected in our laboratory, and recommend future research directions for the possible development of AMPA PAMs as anti-addiction medications.
