So there you go. Target achieved. There is one little glitch in this approach though. That is how do we handle backward compatibility with older Synapse versions? For instance how can a Synapse 1.2 user, who has a single synapse.xml file, migrate to a new Synapse version? We have provided a solution for that as well. In the new Synapse configuration file hierarchy you can place a synapse.xml file at the top level (alongside with registry.xml). All the mediation components defined in this synapse.xml will be loaded to the service bus at startup along with any other components defined inside the individual directories. So a Synapse 1.2 user can simply copy the existing synapse.xml file to the synapse-config directory in a new Synapse distribution, and it will be picked up by the service bus. In addition to this convenience feature, we are planning on developing some migration tools that can help users to easily migrate an old Synapse configuration file onto a newer version of Synapse ...

Throughout our lifetime, activity-dependent changes in neuronal connection strength enable the brain to refine neural circuits and learn based on experience. Synapses can bi-directionally alter strength and the magnitude and sign depend on the millisecond timing of presynaptic and postsynaptic action potential firing. Recent findings on laboratory animals have shown that neurons can show a variety of temporal windows for spike-timing-dependent plasticity (STDP). It is unknown what synaptic learning rules exist in human synapses and whether similar temporal windows for STDP at synapses hold true for the human brain. Here, we directly tested in human slices cut from hippocampal tissue removed for surgical treatment of deeper brain structures in drug-resistant epilepsy patients, whether adult human synapses can change strength in response to millisecond timing of pre- and postsynaptic firing. We find that adult human hippocampal synapses can alter synapse strength in response to timed pre- and postsynaptic
During postnatal development of CA1 pyramidal neurons, GABAergic synapses are excitatory and established prior to glutamatergic synapses. As interneurons are generated before pyramidal cells, we have tested the hypothesis that the GABAergic interneuronal network is operative before glutamate pyramidal neurons and provides the initial patterns of activity. We patch-clamp recorded interneurons in foetal (69 neurons) and neonatal P0 (162 neurons) hippocampal slices and performed a morphofunctional analysis of biocytin-filled neurons. At P0, three types of interneurons were found: (i) non-innervated silent interneurons (5%) with no spontaneous or evoked synaptic currents; (ii) G interneurons (17%) with GABAA synapses only; and (iii) GG interneurons with GABA and glutamatergic synapses (78%). Relying on the neuronal capacitance, cell body size and arborization of dendrites and axons, the three types of interneurons correspond to three stages of development with non-innervated neurons and ...
Postsynaptic scaffolding proteins ensure efficient neurotransmission by anchoring receptors and signaling molecules in synapse-specific subcellular domains. In turn, posttranslational modifications of scaffolding proteins contribute to synaptic plasticity by remodeling the postsynaptic apparatus. Though these mechanisms are operant in glutamatergic synapses, little is known about regulation of GABAergic synapses, which mediate inhibitory transmission in the CNS. Here, we focused on gephyrin, the main scaffolding protein of GABAergic synapses. We identify a unique phosphorylation site in gephyrin, Ser270, targeted by glycogen synthase kinase 3β (GSK3β) to modulate GABAergic transmission. Abolishing Ser270 phosphorylation increased the density of gephyrin clusters and the frequency of miniature GABAergic postsynaptic currents in cultured hippocampal neurons. Enhanced, phosphorylation-dependent gephyrin clustering was also induced in vitro and in vivo with lithium chloride. Lithium is a GSK3β ...
The loss of hippocampal and cortical synapses, resulting from impaired synaptogenesis, accelerated synaptic degeneration, or both, is one of the earliest neuropathologic findings in Alzheimers Disease and is the finding that best correlates with cognitive symptoms (DeKosky & Scheff, 1990; Terry, et al, 1991; Selkoe, 2002). A similar decrease in brain synapses is an early finding in an animal model of AD which overproduces A-beta peptides (Jacobsen, et al, 2006), and aggregates of such peptides, applied locally to the brain, can also damage synapses, distort neurites, and decrease the numbers of the dendritic spines which are essential precursors for glutamatergic synapses (Jacobsen, et al, 2006; Knobloch & Mansuy, 2008; Spires-Jones, et al, 2007). These observations have supported the widely-held view that a treatment that would block the synthesis of A-beta or remove it from the circulation, might - by depleting its levels in brain - slow the loss of synapses in AD and thereby sustain cognitive
The neurons of the dorsal periaqueductal nucleus of the mesencephalon and their synaptic contacts were observed under a transmission electron microscope. We found various types of synapses which constituted an exception to Cajals neuron theory (law of neuron independence). Some of these synapses had an open communicating or continuity passage between the presynaptic bouton of a neuron (first neuron) and the postsynaptic portion of another neuron (second neuron). The communicating passage (located in the synaptosome) is formed by the continuity of the presynaptic and postsynaptic membrane, and its limits or rims are the reflexion points of the membranes. When only two neurons intervene they could be termed simple communicating synapses. We found three types: I = communicating axosomatic synapses; II = communicating axodendritic synapses, and III = communicating axoaxonic synapses. When three neurons intervene in the synaptic contact, they could be termed complex communicating synapses. In these
Thanks to simultaneous "calcium imaging", they were then able to observe and record the activity of individual synapses under a two-photon microscope. In this way, they succeeded in showing for the first time how synapses are arranged with respect to each other.. The result of such synapse mapping analysed with a newly developed algorithm was clear: The synapses of pyramidal cells form clusters consisting of 4 to 14 synapses arranged within an area of less than 30 micrometres along the dendrite. "The existence of these clusters suggests that the synapses interact with each other to control the strength of the combined signal," explains Onur Gökçe, author of the study.. This is the first anatomical explanation for the disproportionate strength of clustered synapse signals in comparison to the individual signals - a finding known from activity measurements. The observation in layer 5 pyramidal cells was of particular interest, as the activity of these cells oscillates synchronously. "This ...
In the present study, we investigated the synaptic association of SAP-97, PSD-93, SAP-102, and PSD-95 during postnatal development in the rat hippocampus. Our major findings show that (1) SAP-102 is present at high levels at most synapses at P2 and decreases through 6 months of age, whereas PSD-95 and PSD-93 are low at P2 and increase through 6 months; (2) Increases in synaptic PSD-95 are attributable primarily to an increase in the number of synapses containing PSD-95, whereas decreases in SAP-102 result from a decrease in both the number of synapses containing SAP-102 and the density of SAP-102 labeling in the synapse; (3) immunogold co-localization shows that multiple MAGUKs are expressed at the same synapse, indicating that PSD-93 and PSD-95 may be added to synapses that already contain SAP-102; (4) the developmental increase in synaptic PSD-93/95 correlates with increases in NR2A; immunoprecipitation does not show a strict relationship between NR2A and PSD-93/95 or NR2B and SAP-102 but ...
Synapses are functional connections between neurons, or between neurons and other types of cells.[4][5] A typical neuron gives rise to several thousand synapses, although there are some types that make far fewer.[6] Most synapses connect axons to dendrites,[7][8] but there are also other types of connections, including axon-to-cell-body,[9][10] axon-to-axon,[9][10] and dendrite-to-dendrite.[8] Synapses are generally too small to be recognizable using a light microscope except as points where the membranes of two cells appear to touch, but their cellular elements can be visualized clearly using an electron microscope. Chemical synapses pass information directionally from a presynaptic cell to a postsynaptic cell and are therefore asymmetric in structure and function. The presynaptic axon terminal, or synaptic bouton, is a specialized area within the axon of the presynaptic cell that contains neurotransmitters enclosed in small membrane-bound spheres called synaptic vesicles (as well as a number ...
Part of the first shipment I ever received from Tom Bihn was the Synapse (now called the Synapse 19). I bought it alongside the Aeronaut (now called the Aeronaut 45) and the Co-Pilot. The Synapse has been over the last four years my go-to bag. While I take my Smart Alec to work every day because I need extra space in my bag, the Synapse is the bag I grab if Im going out for the day whether it be in the city or out in the country. The reason I always reach for the Synapse is the same reason people always tell me they wouldnt want a Synapse (19) - because its small. Ive bought a lot of big backpacks over the years, and I never want to carry them because theyre too big. Its the size of the Synapse that makes it so useful. Its never too big, and I always manage to fit more into it than I would imagine that I could.. The Synapse has a pretty spacious main compartment with a stretchy inside pocket thats good for keeping things from mushing up against your back. There are two side pockets. I ...
The human brain is made up of around 100 billion nerve cells, each of which is connected to other cells by several hundred to thousands of synapses. Apart from our organ and physiological functions, the way we think, act and feel are controlled by the synaptic transmission of information - many quadrillion impulses occur every second. Excitatory synapses that pass the information between cells and inhibitory synapses that limit and change the flow of information are needed for this huge flow of data to run on regulated tracks.. Any disruption to the function of the inhibitory synapses shows how important the suppression of unwanted signals is: there is increased excitation of the brain, such as is seen in epilepsy. Moreover, in order to learn or to remember, the brain needs nerve cells that regulate the activity of other nerve cells. The majority of these inhibitory synapses dock onto the receiver unit of the target cell, the dendrites. Until now, however, there has been no research into exactly ...
The locations and shapes of synapses are important in reconstructing connectomes and analyzing synaptic plasticity. However, current synapse detection and segmentation methods are still not adequate for accurately acquiring the synaptic connectivity, and they cannot effectively alleviate the burden of synapse validation. We propose a fully automated method that relies on deep learning to realize the 3D reconstruction of synapses in electron microscopy (EM) images. The proposed method consists of three main parts: (1) training and employing the faster region convolutional neural networks (R-CNN) algorithm to detect synapses, (2) using the z-continuity of synapses to reduce false positives, and (3) combining the Dijkstra algorithm with the GrabCut algorithm to obtain the segmentation of synaptic clefts. Experimental results were validated by manual tracking, and the effectiveness of our proposed method was demonstrated. The experimental results in anisotropic and isotropic EM volumes demonstrate the

Stereological methods were used in this study to ensure accurate and unbiased quantification of synapse numbers in antennal lobes of the brain. To establish an appropriate sampling regimen, however, it was necessary to obtain some indication of the size and distribution of synapses in the antennal lobes of the bee. Synapse size data were used to determine the distance between disector pairs, and distribution data were used to determine the intensity of sampling required. Synapse complexity was examined also to provide a preliminary assessment of potential changes in connectivity.. Synapse size and complexity. Synapse size was calculated from measurements of how many consecutive sections a synapse was observed to span; the number of postsynaptic processes associated with each presynaptic process provided a measure of synapse complexity. Because both of these features may be age- or activity-dependent, size and complexity of synapses was examined for each glomerulus in a newly emerged adult ...
Brain synapse. Anatomical computer artwork of a human brain with an enlargement showing the structure of a synapse (lower right) within one of the striate bodies that make up the striatum. A synapse is the junction between two nerve cells (neurons). As the electrical signal reaches the presynaptic end of a neuron it triggers the release of neurotransmitters (dots, lower centre). These chemicals travel across the gap (synaptic cleft) between the two cells and initiate a nerve impulse in the postsynaptic neuron. - Stock Image C015/4530
Paired recordings from the calyx of Held synapse in both mice and rats reveals a significant leftward shift of the input-output relationship (ICa-IEPSC), indicating a developmental upregulation in the release efficiency [46, 49]. It has been well documented that the ICa density, or total number of VGCCs on the presynaptic terminal, remains relatively unchanged throughout the development of the calyx of Held synapse [36, 50]. This raises the question: how smaller ICa, evoked by a narrow AP at mature synapses, can yield higher quantal output than that evoked by a wide AP at immature synapses? Intuitively, downstream coupling of Ca2+ entry to vesicular release must enhance fusion efficiency to compensate for the reduced presynaptic input.. There are two possible mechanisms underlying such an enhancement: (1) the spatial coupling between VGCCs and SVs in AZs tightens so that the Ca2+ sensors on SVs are exposed to higher local Ca2+ concentrations near the mouth of VGCCs opened during an AP, and/or ...
During the development of the nervous system synapses are made and broken giving rise to functional neural networks. Even after this stage of initial organisation is complete synapses are still formed and eliminated in response to use, disuse or injury. Thus an important aspect of the nervous system to understand is the mechanisms guiding synapse formation and elimination. The neuromuscular junction is a useful system to use in order to study synapses for two reasons. Firstly, it is easily accessible and easy to manipulate. Secondly, understanding the development of the neuromuscular junction is in itself an important component of the bigger problem of discovering how to deal with disease or injury of the neuromuscular system. The aim of this project is to investigate the principles of synapse formation and elimination at the neuromuscular junction. More specifically the project aims to address the following questions: 1. What are the contributions of "competition" and "intrinsic withdrawal" in ...
I focused on the analysis of a very promising candidate gene, the Mlf1 adapter molecule (Madm). In this study, we implicate for the first time a central role for Madm in the nervous system. Madm is a pseudo kinase which was previously shown to be an adaptor for unknown growth-related signaling pathways in Drosophila (Gluderer S. et al. 2010). We demonstrate that Madm controls multiple aspects of synapse development and refinement at the Drosophila neuromuscular junction (NMJ). First, Drosophila madm mutants displayed prominent synaptic stability and degeneration defects. Second, Madm mutant animals showed severe morphological alterations as well as reduced growth of NMJs. Third, nerves in Madm mutant animals displayed huge swellings and varicosities - a hallmark of neurodegenerative diseases in mammals and humans e.g. in Parkinsons and Alzheimers disease. Fourth, Madm depletion resulted in the accumulation of the presynaptic marker Bruchpilot (BRP) in motoneuron axons. In addition, we could ...

Synaptic activity triggers a profound reorganization of the molecular composition of excitatory synapses. GluN2B/CaMKII binding reduces synapse number it increases synaptic-GluN2B content. Therefore the GluN2B/CaMKII association controls synapse density and PSD composition in an activity-dependent manner including recruitment of CK2 to remove GluN2B from synapses. NSC 687852 INTRODUCTION The molecular composition of the postsynaptic density (PSD) at excitatory synapses is profoundly modified in response to synaptic activity including changes in receptors scaffolding proteins and signaling enzymes (Ehlers 2003 Glutamate receptors are important constituents of PSDs and the dynamic regulation of their synaptic expression is a central mechanism for modulating the strength of excitatory neurotransmission. Therefore glutamate receptors are subject to strict controlling mechanisms that allow both short- and long-term modifications in their number localization and composition in a cell- and ...

Synapse. Coloured Transmission Electron Micrograph (TEM) of a synapse, the junction between two nerve cells. Synapses transmit an electrical signal from one nerve cell to the next in only one direction. In this case, the pre-synaptic cell is blue, the post-synaptic cell is pink. When an electrical signal reaches a synapse it stimulates the release of chemicals called neurotransmitters from tiny vesicles (pink circles) at the end of the cell. The neurotransmitters then cross a microscopic gap and bind to the receptor nerve cell, passing on the signal. Synapses are found at the junctions of all nerve cells and at the junctions between nerve cells and muscles. Magnification unknown. - Stock Image P360/0106
excitatory postsynaptic potential (EPSP) will not reach the threshold for action potential initiation. In the brain, however, each neuron forms synapses with many others, and, likewise, each receives synaptic inputs from many others. When action potentials fire simultaneously in several neurons that weakly synapse on a single cell, they may initiate an impulse in that cell even though the synapses are weak. This process is known as summation. On the other hand, a presynaptic neuron releasing an inhibitory neurotransmitter such as ...
Installing the OCZ Synapse is easy and straightforward - just plug-in the SATA and the power cables. The Synapse series is compatible with any Windows 7 system with a SATA II or SATA III interface. And of course, the DataPlex Caching Software should be installed in order to to the basic cache job.. Synapse SSD can be also installed as a cache for RAID configurations. Fault tolerance for the RAID array will be the same as before the use of the caching software. If the RAID array is configured as RAID1 or better, then you should not encounter any data loss if one or more HDDs fail. In order for the cache to work properly, you must set up your system to have all your data and applications on one primary hard drive or SSD. Synapse can only cache from one existing system boot drive at this time. We start our tests by installing the OCZ Synapse 64GB SSD to a Z-68 system, which already supports another SSD caching solution, the Intel Smart Response Technology. Both Dataplex and SRT are host-based, ...
So, this is likely the most important question you may have. Because as with any product, the "most popular" doesnt necessarily mean it performs the best. Max Synapse Advanced Brain Support on the other hand have reached the scale of both "popularity and performance", hence being the top memory booster of 2016.

Because from our experience researching brands of brain health and cognitive performance supplements, most brands out there does not make any guarantees. Therefore you may find brain supplements that appear to be similar on Amazon or Ebay for a fairly ...
Author Summary The circuitry of the brain is defined by the connections (synapses) between its cells. Synapses are very small, so it is difficult to identify more than a few at a time using standard methods like electron microscopy or high-precision electrical recordings from cells. This study shows that it is possible to measure single synapses using low-precision methods such as optical recordings from neuronal cell bodies. I model optical or electrical stimulation of many inputs to trigger a visible response from neurons, and find single synapses by testing how this response is modulated when a single additional input synapse is triggered as well. I predict that it should be possible to record from as many as a million synapses using new optical recording and stimulation methods. It is believed that memories are encoded in synaptic connection patterns, so such connectivity data may give us a picture of how memories are encoded. We now know a great deal about how individual neurons behave, so a
Synaptic plasticity at excitatory glutamatergic synapses is believed to be instrumental in the maturation of neuronal networks. Using whole-cell patch-clamp recordings, we have studied the mechanisms of induction and expression of long-term depression at excitatory GABAergic synapses in the neonatal rat hippocampus (LTD(GABA-A)). We report that the induction of LTD(GABA-A) requires a GABA(A) receptor-mediated membrane depolarization, which is necessary to remove the Mg(2+) block from postsynaptic NMDA receptors. LTD(GABA-A) is associated with an increase in the coefficient of variation of evoked GABA(A) receptor-mediated synaptic currents and a decrease in the frequency, but not amplitude, of Sr(2+)-induced asynchronous GABA(A) quantal events. We conclude that LTD(GABA-A) induction requires the activation of both GABA(A) and NMDA postsynaptic receptors and that its expression is likely presynaptic. ...
The first evidence that glutamatergic synapses in the hippocampus could signal exclusively via NMDA receptors came from analyzing the trial-to-trial amplitude fluctuations of excitatory postsynaptic currents (EPSCs) recorded in CA1 pyramidal neurons in acute rodent brain slices (Kullmann, 1994). The two components of excitatory transmission evoked by stimulating presynaptic axons (Schaffer collaterals of CA3 pyramidal neurons) were isolated by sequentially clamping the postsynaptic membrane potential at a negative value (around -70 mV) to ensure that NMDA receptors were blocked by Mg2+ ions, and then at a positive value (around +40 mV) in the presence of AMPA receptor blockers to reveal NMDA receptor-mediated signaling. If both AMPA and NMDA receptors were present at all synapses, the variability of each component of the postsynaptic signal, expressed as the coefficient of variation (CV), should be approximately equal. This is because CV (the ratio of standard deviation to mean amplitude) is ...
Neurons in a micro-circuit connected by chemical synapses can have their connectivity affected by the prior activity of the cells. The number of synapses available for releasing neurotransmitter can be decreased by repetitive activation through depletion of readily releasable neurotransmitter (NT), or increased through facilitation, where the probability of release of NT is increased by prior activation. These competing effects can create a complicated and subtle range of time-dependent connectivity. Here we investigate the probabilistic properties of facilitation and depression (FD) for a presynaptic neuron that is receiving a Poisson spike train of input. We use a model of FD that is parameterized with experimental data from a hippocampal basket cell and pyramidal cell connection, for fixed frequency input spikes at frequencies in the range of theta (3-8 Hz) and gamma (20-100 Hz) oscillations. Hence our results will apply to micro-circuits in the hippocampus that are responsible for the interaction of
Along with regulating synaptic transmission, voltage-gated calcium channel (VGCC) function is responsible for a myriad of cellular outputs, ranging from gene expression to shaping synaptic morphology. Despite the morphological role of VGCCs, the proteins working downstream of VGCCs to regulate synaptic morphology remain mostly unknown, and their identification would provide insight into the shaping of synapses through calcium signaling. Chapter I introduces the Caenorhabditis elegans VGCC subunits unc-2 and unc-36 as regulators of D-type GABAergic neuromuscular junction morphology. In addition to synaptic defects found in single mutants, loss-of-function mutations in VGCC subunits, independent of neurotransmission, suppressed the enlarged synaptic areas resulting from mutations in the extracellular matrix protein nidogen (nid-1). Furthermore, time-lapse microscopy revealed UNC-2 function was required for proper synaptic dynamics that occurred during the L4 larval stage of organismal growth. ...
Previous work showed differences in the polysynaptic activation of GABAergic synapses during corticostriatal suprathreshold responses in direct and indirect striatal projection neurons (dSPNs and iSPNs). Here, we now show differences and similarities in the polysynaptic activation of cortical glutamatergic synapses on the same responses. Corticostriatal contacts have been extensively studied. However, several questions remain unanswered, e.g.: what are the differences and similarities in the responses to glutamate in dSPNs and iSPNs? Does glutamatergic synaptic activation exhibits a distribution of latencies over time in vitro? That would be a strong suggestion of polysynaptic cortical convergence. What is the role of kainate receptors in corticostriatal transmission? Current-clamp recordings were used to answer these questions. One hypothesis was: if prolonged synaptic activation distributed along time was present, then it would be mainly generated from the cortex, and not from the striatum. ...
Neural connections require precise organization of the presynaptic and postsynaptic neurons. Neuroligins are transmembrane proteins expressed on the postsynaptic cell that bind to β-neurexins, which are presynaptic transmembrane proteins. Graf et al. report that β-neurexin is present in both excitatory (glutamatergic) and inhibitory (GABAergic) presynaptic neurons of the hippocampus. When these cells were plated with COS cells transfected to express neuroligin-1 or neuroligin-2, the presynaptic specializations that contained synaptic vesicles were induced in both types of axons. Coculture of fibroblasts expressing neurexin-1β with hippocampal neurons triggered the formation of PSD-95-positive or gephyrin-positive postsynaptic clusters in contacting dendrites (PSD-95 is an excitatory postsynaptic organizing protein and gephyrin is an inhibitory postsynaptic organizing protein). In addition, neurexin-1β stimulated clustering of N-methyl-D-aspartate (NMDA)-type glutamate receptor subunits and ...

Rapid signaling between vertebrate neurons occurs primarily at synapses, intercellular junctions where quantal release of neurotransmitter triggers rapid changes in membrane conductance through activation of ionotropic receptors. Glial cells express many of these same ionotropic receptors, yet little is known about how receptors in glial cells become activated in situ. Because synapses were thought to be the sole provenance of neurons, it has been assumed that these receptors must be activated following diffusion of transmitter out of the synaptic cleft, or through nonsynaptic mechanisms such as transporter reversal. Two recent reports show that a ubiquitous class of progenitors that express the proteoglycan NG2 (NG2 cells) engage in rapid signaling with glutamatergic and gamma-aminobutyric acid (GABA)ergic neurons through direct neuron-glia synapses. Quantal release of transmitter from neurons at these sites triggers rapid activation of aminomethylisoxazole propionic acid (AMPA) or GABA(A) ...

For example, a post-operative care app for hip replacement that enables a patient to track pain medication usage, monitor for surgical site infection, track mobility metrics, and communicate with the care team, ...
Synapse supported the National Association of State Utility Consumer Advocates and its members in addressing the EPAs proposed Clean Power Plan in a manner that is cost-effective and efficient from an electricity consumer perspective.. Prior to the release of the rule, Synapse presented to NASUCA members key issues regarding the details of the proposed rule and the primary compliance options that may be available to states. Following the rules release, Synapse prepared a report focusing on the details of the rule as proposed. Recognizing that stakeholders have a wide range of reactions to the EPAs Plan, the intent of the report is to be a common resource to help all of NASUCAs members think through a broad range of potential implications of various compliance approaches to their respective consumers-whatever their individual states positions. Synapse presented on the findings of Implications of EPAs Proposed "Clean Power Plan" at the 2014 NASUCA annual meeting in San Francisco, ...

Mind Games. Everyone plays them, mostly with themselves. Black Scale brings out their long-time fam DJ Synapse, for their April mix to bring you Mind Games. These are the Mind Games of DJ Synapse, a New York stalwart, and brand developer of 15 years. The songs in this mix were blended live with two Technics, a Rane mixer and Pioneer EFX-500 box. The songs were completely new to Synapse when he mixed them, so its an improvisational affair. After blending the songs (22 in 30 minutes), Synapse laid his cut, paste and scratch flavor, to the mix, something he has always been known for. These Mind Games are an attempt at a new way of looking at mixing. ...

NPTN isoform p65 binds GABAA receptor subunits, co-localizing with alpha1 and alpha2, but not alpha3 subunits at GABAergic synapses and alpha5 subunits at extrasynaptic sites in cultures (Sarto-Jackson et al. 2012). GABAA receptors containing alpha1, 2 or 3 subunits are localized mainly at synaptic sites and interact with the scaffolding protein Gephyrin (GPHN), which anchors the receptor to the underlying postsynaptic complex and prevents their lateral diffusion (Kneussel & Loebrich 2007, Tretter et al. 2012). Receptors containing the alpha5 subunit are mainly extrasynaptic and link to the actin cytoskeleton via Radixin (Loebrich et al. 2006). NPTN p65 co-localization can be at several synaptic sites along the same dendrite, while absent from others. NPTN p65 shRNA caused diffuse alpha2 subunit staining which did not co-localize with vesicular inhibitory aa transporter, a presynaptic marker of GABAergic synapses (Sarto-Jackson et al. 2012). This suggests a functional role for NPTN p65 in ...
