Long-term potentiation (LTP) is arguably the most compelling cellular model for learning and memory. While mechanisms underlying induction of LTP ('learning') are well understood, maintenance ('memory') has remained contentious over last 20 years. Here, we find that Ca

Many physiologic effects of l-glutamate, the major excitatory neurotransmitter in mammalian central nervous system, are mediated via signaling by ionotropic glutamate receptors (iGluRs). These ligand-gated ion channels critical to brain function and centrally implicated numerous psychiatric neurologic disorders. There different classes iGluRs with a variety receptor subtypes each class that play distinct roles neuronal functions. The diversity iGluR subtypes, their unique functional properties roles, has motivated large number studies. Our understanding advanced considerably since first subunit gene was cloned 1989, research focus expanded encompass facets biology have been recently discovered exploit experimental paradigms made possible technological advances. Here, we review insights from more than 3 decades studies an emphasis on progress occurred past decade. We cover structure, function, pharmacology, neurophysiology, therapeutic implications for all assembled subunits encoded 18 genes. SIGNIFICANCE STATEMENT: Glutamate important virtually aspects either involved mediating some clinical features neurological disease or represent target treatment. Therefore, pharmacology this will advance our many at molecular, cellular, system levels provide new opportunities treat patients.

Wnt signaling plays a major role in regulating cell proliferation and differentiation. The ligands are family of 19 secreted glycoproteins that mediate their effects via binding to Frizzled receptors LRP5/6 coreceptors transducing the signal either through β-catenin canonical pathway or series other proteins noncanonical pathway. Many individual components both have additional functions throughout body, establishing complex interplay between pathways. This crosstalk pathways gives vital many cellular organ processes. Dysregulation this system has been implicated diseases affecting wide array systems, including cancer embryological defects, can even cause embryonic lethality. complexity its interacting made target for therapeutic treatments.

Ca 2+ /calmodulin-dependent protein kinase II (CaMKII) and long-term potentiation (LTP) were discovered within a decade of each other have been inextricably intertwined ever since. However, like many marriages, it has had its up downs. Based on the unique biochemical properties CaMKII, was proposed as memory molecule before any physiological linkage made to LTP. reviewed here, convincing CaMKII synaptic physiology behavior took decades. New technologies critical in this journey, including vitro brain slices, mouse genetics, single-cell molecular pharmacological reagents, structure, two-photon microscopy, new investigators attracted by exciting challenge. This review tracks journey assesses state marriage 40 years on. The collective literature impels us propose relatively simple model for involving following steps that drive process: 1) entry through N-methyl-d-aspartate (NMDA) receptors activates CaMKII. 2) undergoes autophosphorylation resulting constitutive, -independent activity exposure binding site NMDA receptor subunit GluN2B. 3) Active translocates postsynaptic density (PSD) binds cytoplasmic C-tail 4) CaMKII-GluN2B complex initiates structural rearrangement PSD may involve liquid-liquid phase separation. 5) involves PSD-95 scaffolding protein, α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPARs), their transmembrane AMPAR-regulatory (TARP) auxiliary subunits, an accumulation AMPARs underlies potentiation. 6) stability modified is maintained complex. 7) By process exchange or interholoenzyme phosphorylation maintains face turnover. There are important proteins participate enlargement spine modulation maintain In we critically discuss data underlying steps. As will become clear, some these more firmly grounded than others, provide suggestions how evidence supporting can be strengthened or, based data, replaced.

Abstract The N ‐methyl‐ D ‐aspartate receptors (NMDARs) are ionotropic glutamate that mediate the flux of calcium (Ca 2+ ) into post‐synaptic compartment. Ca influx subsequently triggers activation various intracellular signalling cascades underpin multiple forms synaptic plasticity. Functional NMDARs assembled as heterotetramers composed two obligatory GluN1 subunits and GluN2 or GluN3 subunits. Four different (GluN2A‐D) present throughout central nervous system; however, they differentially expressed, both developmentally spatially, in a cell‐ synapse‐specific manner. Each subunit confers with distinct ion channel properties trafficking pathways. Regulated membrane is dynamic process ultimately determines number at synapses, controlled by subunit‐specific interactions regulatory proteins. Here we review recent progress made towards understanding molecular mechanisms regulate GluN2‐containing NMDARs, focusing on roles several key proteins interact via their carboxyl termini. image

Posttranscriptional gene expression including splicing, RNA transport, translation, and decay provides an important regulatory layer in many if not all molecular pathways. Research the last decades has positioned RNA-binding proteins (RBPs) right center of posttranscriptional regulation. Here, we propose interdependent networks RBPs to regulate complex pathways within central nervous system (CNS). These are involved multiple aspects neuronal development functioning, higher cognition. Therefore, it is sufficient unravel individual contribution a single RBP its consequences but rather study understand tight interplay between different RBPs. In this review, summarize recent findings field biology discuss Second, emphasize underlying dynamics network how might key processes such as neurogenesis, synaptic transmission, plasticity. Importantly, envision that dysfunction specific could lead perturbation network.
