Advanced Science, EarlyView.The present study shows that Nrf2 directly binds to the Gm26550 promoter, thereby activating Gm26550 transcription and increasing its expression. Mechanistically, Gm26550 promotes IGF1 expression by functionally antagonizing miR‐26a‐5p‐mediated repression and sequestering the RBP KHSRP, thereby enhancing hippocampal neuronal synaptic plasticity and ...

Regulation of Dendrite and Dendritic Spine Formation by
Journal of NeurochemistryABSTRACT Mutations in the Transcription Factor 20 (TCF20) have been identified in patients with autism spectrum disorders (ASDs), intellectual disabilities (IDs), and other neurological issues. Recently, a new syndrome called TCF20‐associated neurodevelopmental disorders (TAND) has been described, with specific ...

Growth of dendritic spines: a continuing story.
, 2005 Dendritic spines, which are present at the vast majority of excitatory synapses in the central nervous system, have a specialized cytoskeleton of dynamic actin filaments that makes them capable of rapid morphological plasticity.

Actin cytoskeleton in dendritic spine
Folia Pharmacologica Japonica, 2007 樹状突起スパインは脳内の主要な興奮性シナプス後部であり，その形態および構成タンパク質の可塑的変化は学習記憶などの高次機能に重要である．スパイン内の構造体としては，シナプス後部肥厚（PSD）とアクチン細胞骨格があり，スパインの形態変化は主にアクチン細胞骨格により制御されている．スパイン内ではその頭部と頸部でアクチン線維の構造が異なることに加えて，頭部の中でもシナプス直下のPSD近傍と細胞質の中心領域でアクチン結合タンパク質の分布が異なる．したがって，スパインは3種類の性質の異なるアクチン細胞骨格によって構成されていると考えられる．アクチンを脱重合させると，多くのスパイン構成タンパク質の局在が不安定化し，スパイン形態もフィロポディア様に変化する．従って，アクチン細胞骨格がスパイン形態の形成 ...

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity
Advanced Science, EarlyView.This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

An image analysis algorithm for dendritic spines
, 2002 The structure of neuronal dendrites and their spines underlie the connectivity of neural networks. Dendrites, spines, and their dynamics are shaped by genetic programs as well as sensory experience.
