Synaptopathy in the cochlea occurs when the connection between inner hair cells and the auditory nerve is disrupted, leading to impaired hearing and nerve degeneration. Experiments using transgenic mice have shown that overexpression of NT3 by supporting cells repairs synaptopathy caused by overstimulation. To accomplish such therapy in the clinical setting, it would be necessary to activate th...
چکیده زمینه وهدف: آسیب به اعصاب محیطی موجب مرگ تعدادی از سلول های حرکتی نخاع می شود. ژن های خانواده نوروتروفین از جمله nt3 در بقای نورونی دخالت دارند و پس از آسیب عصب، میزان بیان آن ها تغییر می کند. با توجه به گستردگی گیاه خرفه (portulaca oleracea) در دنیا، این پژوهش به منظور تعیین اثرات عصاره الکلی و آبی خرفه بر میزان بیان ژنnt3 پس از آسیب عصب سیاتیک در رت انجام شد. مواد و روش ها: این مطالعه ...
Introduction: There are several hypotheses of schizophrenia pathogenesis, including the neurodegenerative theory, which is supported by evidence for decrease neuroprotective factors’ serum levels. The proteins, that exert a protective effect on neurons and researched concerning include brain-derived neurotrophic factor (BDNF), nerve growth (NGF), neurotrophin 3 (NT3), glial cell line-derived (G...
Aims: To investigate the staining pattern of neurotrophin-3 (NT3), neurotrophin-4 (NT4), and brain derived neurotrophic factor (BDNF) as well as glial fibrillary acid protein (GFAP) and CD68 in lasered human retina. Methods: Retinal laser photocoagulation was performed on four patients (two males, two females) with choroidal malignant melanoma 1–6 days before enucleation. Three other enucleated...
Transmission through descending pathways to lumbar motoneurons, although important for voluntary walking in humans and rats, has not been fully understood at the cellular level in contusion models. Major descending pathways innervating lumbar motoneurons include those at corticospinal tract (CST) and ventrolateral funiculus (VLF). We examined transmission and plasticity at synaptic pathways fro...
Introduction: Neurotrophic factors change in response to nerve damage. Stachyslavandulifolia belongs to the Laminaceae family and since tea has antioxidant and anti-inflammatory effects, therefore, this study aimed to determine the effects of hydroalcoholic extract of mountain tea and its effect on NT3 gene expression after compression. Methods: In this experimental study, at first the hydro-a...
We have previously reported that 5 copies of the hypoxia response element (HRE) can conditionally regulate brain-derived neurotrophic factor gene expression under hypoxic/ischemic conditions in mice. In the present study, we investigated the controlled expression of neurotrophin-3 (NT-3) by HRE under hypoxic conditions and determined the protectiv...

مقدمه: بیان فاکتورهای نوروتروفیک که باعث افزایش بقاء و ترمیم نورون ها می شوند، بیانشان در پاسخ به آسیب عصب تغییر می یابد. قارچ قیفی(cantharellus cibarius) دارای اثرات آنتی اکسیدانی و ضدالتهابی است؛ لذا این پژوهش با هدف تعیین اثرات عصاره هیدروالکلی قارچ قیفی و تأثیر آن بر روی میزان بیان ژن nt3 و ngf پس از کمپرسیون عصب سیاتیک در رت انجام شده است. روش بررسی: ابتدا عصاره هیدروالکلی قارچ قیفی با روش...
