غالب ضایعات نخاعی موجب از بین رفتن عملکرد اعصاب حسی و حرکتی در بخش تحتانی ناحیه آسیب دیده می گردند. نخاع یک فرد بالغ قادر است با سازماندهی مجدد اتصالات آکسونها و ایجاد سلولهای پیش ساز جدید، به ضایعات ایجاد شده در این اندام پاسخ دهد. پیوند سلولهای بنیادی/اجدادی با تولید سلولهای گلیایی و نورونها، استراتژیهای ترمیمی اندوژن را تشدید کرده و با کاهش عوارض آسیبها کیفیت زندگی بیماران مزمن مبتلا به ضایع...
Background: Bone marrow stromal cells (BMSC) have been successfully employed for movement deficit recovery in spinal cord injury (SCI) rat models. One of the unsettled problems in cell transplantation is the relative high proportion of cell death, specifically after neural differentiation. According to our previous studies, p75 receptor, known as the death receptor, is only expressed in BMSC in...
Introduction: Current study aimed to investigate the effects of resistance training (RT) along with royal jelly (RJ) supplementation on hippocampal expression of nerve growth factor (proNGF) and p75 receptor in a rat’s model of Alzheimer's disease. Method: 42 male Sprague-Dawley rats were treated with Trimethyltin chloride (8 mg/kg). Then, the rats were randomly divided into seven equal group...

A member of the TNF receptor family, the p75 neurotrophin receptor (p75(NTR)) has been previously shown to play a role in the regulation of fibrin deposition in the lung. However, the role of p75(NTR) in the regulation of pulmonary vascular tone in the lung is unknown. In the present study, we evaluated the expression of p75(NTR) in mouse pulmonary arteries and the putative role of p75(NTR) in ...
هدف از تحقیق حاضر مطالعه ی اثر یک جلسه فعالیت مقاومتی بر بیانmrna پروتئین های nt-4/5، bdnf،trkb وp75 در عضلات کند انقباض (نعلی) و تند انقباض (fhl) موش های صحرایی بود. بدین منظور تعداد 16 سر موش نر ویستار (4 ماه سن، خریداری شده از موسسه پاستور) به طور تصادفی در دو گروه کنترل (8=n) و گروه فعالیت مقاومتی (8=n) قرار گرفتند. بالارفتن از نردبانی به ارتفاع 1 متر که داری 26 پله و زاویه 85 درجه نسبت به ...
The p75 neurotrophin receptor (p75(NTR)) is a member of the tumor necrosis factor receptor superfamily with a widespread pattern of expression in tissues such as the brain, liver, lung, and muscle. The mechanisms that regulate p75(NTR) transcription in the nervous system and its expression in other tissues remain largely unknown. Here we show that p75(NTR) is an oscillating gene regulated by th...
Neuroblastomas (NBs) with favorable outcome usually express TrkA, whereas unfavorable NBs frequently express TrkB and its cognate ligand BDNF. P75 (p75(LNTR), NGFR, TNFRSF16) binds NGF-related neurotrophins with low affinity and usually is coexpressed with Trk receptors in NBs. Here, we investigated the importance of p75 coexpression with Trk receptors in NBs. We transfected p75 into two Trk-nu...
The multifunctional signaling protein p75 neurotrophin receptor (p75(NTR)) is a central regulator and major contributor to the highly invasive nature of malignant gliomas. Here, we show that neurotrophin-dependent regulated intramembrane proteolysis (RIP) of p75(NTR) is required for p75(NTR)-mediated glioma invasion, and identify a previously unnamed process for targeted glioma therapy. Express...
