Detection of Arc/Arg3.1 oligomers in rat brain: constitutive and synaptic activity-evoked dimer expression in vivo
Mergiya, Tadiwos Feyissa; Gundersen, Jens Edvard Trygstad; Kanhema, Tambudzai; Brighter, Grant Mitchell; Ishizuka, Yuta; Bramham, Clive Raymond Evjen (Journal article; Peer reviewed, 2023)The immediate early gene product activity-regulated cytoskeleton-associated protein (Arc or Arg3.1) is a major regulator of long-term synaptic plasticity with critical roles in postnatal cortical development and memory ... -
Development and Validation of Arc Nanobodies: New Tools for Probing Arc Dynamics and Function
Ishizuka, Yuta; Mergiya, Tadiwos Feyissa; Baldinotti, Rodolfo Da Silva Mazzarini; Xu, Ju; Hallin, Erik Ingmar; Markusson, Sigurbjörn; Kursula, Petri; Bramham, Clive Raymond Evjen (Journal article; Peer reviewed, 2022)Activity-regulated cytoskeleton-associated (Arc) protein plays key roles in long-term synaptic plasticity, memory, and cognitive flexibility. However, an integral understanding of Arc mechanisms is lacking. Arc is proposed ... -
Discovery and biological characterization of a novel scaffold for potent inhibitors of peripheral serotonin synthesis
Betari, Nibal; Sahlholm, Kristoffer; Ishizuka, Yuta; Teigen, Knut; Haavik, Jan (Journal article; Peer reviewed, 2020)Aim: Tryptophan hydroxylase 1 (TPH1) catalyzes serotonin synthesis in peripheral tissues. Selective TPH1 inhibitors may be useful for treating disorders related to serotonin dysregulation. Results & methodology: Screening ... -
Herpes Simplex Virus Type 1 Neuronal Infection Triggers the Disassembly of Key Structural Components of Dendritic Spines
Acuña-Hinrichsen, Francisca; Covarrubias-Pinto, Adriana; Ishizuka, Yuta; Stolzenbach, María Francisca; Martin, Carolina; Salazar, Paula; Castro, Maite A.; Bramham, Clive Raymond Evjen; Otth, Carola (Journal article; Peer reviewed, 2021)Herpes simplex virus type 1 (HSV-1) is a widespread neurotropic virus. Primary infection of HSV-1 in facial epithelium leads to retrograde axonal transport to the central nervous system (CNS) where it establishes latency. ... -
A Nanobody-Based Proximity Ligation Assay Detects Constitutive and Stimulus-Regulated Native Arc/Arg3.1 Oligomers in Hippocampal Neuronal Dendrites
Da Silva Mazzarini Baldinotti, Rodolfo; Pauzin, Francois Philippe; Fevang, Hauk; Ishizuka, Yuta; Bramham, Clive Raymond Evjen (Journal article; Peer reviewed, 2024)Activity-regulated cytoskeleton-associated protein (Arc), the product of an immediate early gene, plays critical roles in synaptic plasticity and memory. Evidence suggests that Arc function is determined by its oligomeric ... -
A simple DMSO-based method for cryopreservation of primary hippocampal and cortical neurons
Ishizuka, Yuta; Bramham, Clive R. (Peer reviewed; Journal article, 2019-03)Background Primary neuronal cultures are widely used to elucidate fundamental aspects of neuronal anatomy, physiology, cell biology, and neuronal dysfunction in animal models of disease. However, preparation of primary ...
