    MeCP2 regulates Tet1-catalyzed demethylation, CTCF binding, and learning-dependent alternative splicing of the BDNF gene in Turtle

    Zhaoqing Zheng, Ganesh Ambigapathy, Joyce Keifer
    Loss of MeCP2 function negatively impacts Tet1 and CTCF binding thereby negatively impacting learning-dependent DNA methylation and alternative splicing regulation.

    Astrocyte morphogenesis is dependent on BDNF signaling via astrocytic TrkB.T1

    Leanne M Holt, Raymundo D Hernandez ... Michelle L Olsen
    Brain-derived neurotrophic factor (BDNF)/TrkB.T1 signaling contributes to astrocyte morphological maturation, with implications for neuronal synaptogenesis and function and astrocyte functional maturation.

    Chronic lithium treatment elicits its antimanic effects via BDNF-TrkB dependent synaptic downscaling

    Erinn S Gideons, Pei-Yi Lin ... Lisa M Monteggia
    The antimanic action of lithium requires BDNF-TrkB signaling coupled with enhanced dynamin-dependent endocytosis of AMPARs as a potential mechanism underlying the therapeutic effects.

    Oligodendrocytes regulate presynaptic properties and neurotransmission through BDNF signaling in the mouse brainstem

    Miae Jang, Elizabeth Gould ... Jun Hee Kim
    Oligodendrocytes are actively engaged in the precise control of synaptic functions in the CNS through activity-dependent BDNF signaling.

    Rbfox1 up-regulation impairs BDNF-dependent hippocampal LTP by dysregulating TrkB isoform expression levels

    Francesco Tomassoni-Ardori, Gianluca Fulgenzi ... Lino Tessarollo
    RbFox1 upregulation modulates the expression of hundreds of genes but only dysregulation of the TrkB.T1 receptor isoform expression causes BDNF-dependent LTP impairments.

    Loss of MeCP2 disrupts cell autonomous and autocrine BDNF signaling in mouse glutamatergic neurons

    Charanya Sampathkumar, Yuan-Ju Wu ... Christian Rosenmund
    In mouse models of Rett syndrome, the impaired cell autonomous BDNF feed forward signaling pathway results in abnormalities in neurite outgrowth and synapse formation in excitatory neurons.

    Balance between BDNF and Semaphorins gates the innervation of the mammary gland

    Hadas Sar Shalom, Ron Goldner ... Avraham Yaron
    The innervation of the mammary gland is controlled by opposing effects of neurotrophic and repulsive factors and, once trophic signaling is inhibited the repulsive factors, may promote axonal pruning.

    Exercise promotes the expression of brain derived neurotrophic factor (BDNF) through the action of the ketone body β-hydroxybutyrate

    Sama F Sleiman, Jeffrey Henry ... Moses V Chao
    A potential link between metabolic changes resulting from exercise and gene expression in the brain has been revealed.

    BDNF-TrkB signaling in oxytocin neurons contributes to maternal behavior

    Kristen R Maynard, John W Hobbs ... Keri Martinowich
    Brain-derived neurotrophic factor signaling plays a causal role in female-typical social behavior and modulates oxytocin neuron gene expression.

    Intronic enhancer region governs transcript-specific Bdnf expression in rodent neurons

    Jürgen Tuvikene, Eli-Eelika Esvald ... Tõnis Timmusk
    An evolutionarily conserved neuron-specific and stimulus-dependent enhancer region downstream of the Bdnf exon III regulates the expression of Bdnf transcripts starting from the upstream 5' exons.
