\ufeffAll the statistical analyses are compared to respective control neurons with two-tailed Wilcoxon signed-rank sum test. across a structure called a synapse that forms a junction between the cells. The neurotransmitters bind to receptors around the surface from the receiving neuron, and depending on the type of neurotransmitter released, make that neuron either more or less likely to signal to its neighbors. Excitatory neurotransmitters make neurons more likely to signal, and glutamate is the most common excitatory neurotransmitter in the brain. There are several different types of receptor that can hole to glutamate, one of which the kainate receptor is found at relatively few synapses. These synapses include some in the hippocampus, a region of A-9758 the brain that is important for memory. Researchers have recently identified two auxiliary proteins, called Neto1 and Neto2, that interact with kainate receptors and appear to affect how strongly the kainate receptors respond when glutamate binds to them. However , A-9758 A-9758<\/a> the effect of the Neto proteins on one particular subunit of the kainate receptors called GluK1 had not been investigated in depth. CA1 pyramidal neurons are a group of neurons in the hippocampus that are able to produce kainate receptors, but these receptors are not found in CA1 pyramidal neuron synapses. Sheng et al. have now studied CA1 pyramidal neurons from rats, and found that these cells produce a limited amount of GluK1 on their surfaces. However , when GluK1 is expressed together with Neto1 or Neto2, GluK1 receptors appear on the cell surface. Through an independent mechanism Neto proteins also promote the focusing on of surface GluK1 to the synapse. Unexpectedly, GluK1 was excluded from synapses that contain another type of glutamate receptor called AMPA receptors. By measuring the effect of Neto1 and Neto2 around the behavior of GluK1, Sheng et al. found that these proteins modified how the receptor responded to prolonged exposure to glutamate. Specifically, Neto1 increased how quickly GluK1 became desensitized to glutamate, while Neto2 decreased the rate of desensitization. This study demonstrates that Neto proteins play critical roles in controlling the location and biophysical properties of kainate receptors. It can be of interest to see how the present findings apply to other excitatory synapses in the brain. DOI: http:\/\/dx.doi.org\/10.7554\/eLife.11682.002 == Introduction == Most excitatory synaptic transmission in the brain is mediated by glutamate acting on AMPA and NMDA subtypes of glutamate receptors. However , there is a third subtype of ionotropic glutamate receptor termed kainate receptor (KAR) comprising GluK1-5 subunits. These receptors are uncommon in that A-9758 they are expressed at only a subset of glutamatergic synapses Rabbit Polyclonal to MASTL<\/a> (Contractor et al., 2011; Jane et al., 2009; Lerma and Marques, 2013). The most studied synaptic KARs are those expressed at hippocampal CA3 mossy fiber synapses (Nicoll and Schmitz, 2005). These receptors are expressed postsynaptically and generate a slow EPSC. They are also expressed presynaptically and contribute to the profound frequency facilitation, a hallmark of those synapses. In the CA1 region of the hippocampus, KARs are expressed postsynaptically at excitatory synapses in interneurons (Cossart et al., 1998; Frerking et al., 1998). However , no detectable synaptic KAR EPSCs have been recorded from CA1 pyramidal neurons (Bureau et al., 1999; Castillo et al., 1997; Granger et al., 2013), despite the fact that functional KARs are expressed on these neurons (Bureau et al., 1999; Ruano et al., 1995). What might determine whether an excitatory synapse expresses KARs? Recently, auxiliary subunits of KARs, known as Neto1 and Neto2, have been identified (Copits and Swanson, 2012; Straub and Tomita, 2012; Zhang et al., 2009). These neurophilin tolloid-like proteins are single move transmembrane CUB (complement C1r\/C1s, Uegf and Bmp1) domain-containing proteins. Both Neto1 and Neto2 are known to alter the kinetics of KARs (Copits et al., 2011; Straub et al., 2011; Zhang et al., 2009). More specifically Neto2 slows deactivation and desensitization of GluK2 receptors (Zhang A-9758 et al., 2009). Neto1 slows deactivation and desensitization of GluK2\/5 and deletion of Neto1 in mice speeds.<\/p>\n","protected":false},"excerpt":{"rendered":"
