    Article Title: EGR1-mediated repression of HDAC2 regulates BDNF-dependent kindling development in a mouse model of pentylenetetrazol-induced epilepsy.
    Article Snippet: Epilepsy is a chronic neurological condition characterized by recurrent seizures that affects millions of people worldwide.. Recent studies have reported altered expression of early growth response 1 (Egr1), an activityinducible immediate early gene, and histone deacetylase 2 (HDAC2), a regulator of gene transcription through the removal of acetyl groups from histone tails, in the hippocampus of epilepsy patients and animal models.. Here, we investigated the roles of EGR1 and HDAC2 in pentylenetetrazol (PTZ)-induced seizures in kindled mice.

    Article Title: EPHRIN-A1 and -A2 act as positive growth factors for developing spiral ganglion radial bundles.
    Article Snippet: During the formation of the auditory system in mammals, spiral ganglion neurons (SGNs) form ribbon-type synapses with hair cells in the cochlea to establish the first “sensorineural” component of sound transduction.. Ahead of synapse formation in the cochlea, the SGNs undergo migration and extension with developing Schwann and otic mesenchyme cells to form radial bundles, fasciculated groups of nerve fibers found between the SGN somata and hair cells.. Thus far, reports have shown that Eph/Ephrin signaling is important for the formation of radial bundles.

    Article Title: Dysregulated CRTC1-BDNF signaling pathway in the hippocampus contributes to Aβ oligomer-induced long-term synaptic plasticity and memory impairment.
    Article Snippet: Expression of CREB-regulated transcription coactivator 1 (CRTC1) in the hippocampus is impaired in Alzheimer's disease (AD).. However, CRTC1 related mechanisms associated with long-term synaptic plasticity impairment and cognitive decline in the onset of AD are unknown.. In this study, electrophysiological recordings indicated that lentivirus-mediated CRTC1 overexpression effectively ameliorates suppression of late-phase long-term potentiation (L-LTP) in rat hippocampal slices treated with oligomeric amyloid β(1–42) peptides (oAβ42) (200 nM).

    Article Title: BDNF-mediated regulation of GSK-3β and PSD95 phosphorylation in anti-depressive effects of Capsosiphon fulvescens glycoproteins against chronic alcohol exposure
    Article Snippet: Under aseptic conditions, an infusion guide cannula (22-gauge; Plastics One, Roanoke, VA, USA) was implanted using the following coordinates from the bregma: anterior-posterior, − 4.36 mm; dorsal–ventral, − 8.0 mm; and medial–lateral, 4.3 mm. .. After a 28-gauge dummy cannula was inserted to prevent the guide cannula from clogging, the rats were allowed to recover for 5 d. This dummy cannula was replaced with a 28-gauge internal cannula that protruded 0.5 mm beyond the guide cannula, and function-blocking anti-BDNF antibodies (1 μg/μL; Abcam) or recombinant BDNF (1.5 μg/μL; R&D systems, Minneapolis, MN, USA) was infused into the ventral hippocampus. .. All drugs were purchased from Tocris Bioscience (Minneapolis, MN, USA) and diluted with artificial cerebrospinal fluid.
