To determine whether the p75 neurotrophin receptor (p75NTR) plays a role in naturally occurring neuronal death, we examined neonatal sympathetic neurons that express both the TrkA tyrosine kinase receptor and p75NTR. When sympathetic neuron survival is maintained with low quantities of NGF or KCl, the neurotrophin brain-derived neurotrophic factor (BDNF), which does not activate Trk receptors o...
This study evaluated the relative mRNA expression levels of nerve growth factor (NGF) and the p75 neurothrophin receptor (p75NTR) in different histological stages of human liver disease. Fifty-one liver biopsy specimens obtained from patients with hepatitis B virus (n = 6), hepatitis C virus (n = 28), and non-viral hepatitis--(n = 9) and standard histological liver (n = 8) as controls (CT) were...
The neurotrophin receptor p75NTR is the coreceptor for Nogo receptor, mediating growth cone collapse in vitro by MAG, myelin oligodendrocyte glycoprotein (Omgp), and Nogo. Whether p75NTR plays any role in the failure of nerve regeneration in vivo is not known. Immunohistochemical data showed that p75NTR was expressed in only a very small subset of ascending sensory axons but not in any corticos...
Nerve growth factor (NGF) can induce apoptosis in neural cells via activation of the low affinity neurotrophin receptor p75NTR. NADE (p75NTR-associated cell death executor) is a p75NTR-associated protein that mediates apoptosis in response to NGF by interacting with the death domain of p75NTR in 293T, PC12, and nnr5 cells (Mukai, J., Hachiya, T., Shoji-Hoshino, S., Kimura, M. T., Nadano, D., Su...
Decreases in the ratio of neurotrophic versus neurodegenerative signalling play a critical role in Huntington’s disease (HD) pathogenesis and recent evidence suggests that the p75 neurotrophin receptor (NTR) contributes significantly to disease progression. p75NTR signalling intermediates substantially overlap with those promoting neuronal survival and synapse integrity and with those affected ...
In the adult mammalian central nervous system (CNS), growth of neuronal fibers is actively inhibited by myelin. The proteins myelin-associated glycoprotein (MAG), oligodendrocyte myelin glycoprotein (OMgP), and Nogo-66 have been identified as inhibitory components present in CNS myelin. All three proteins exert their inhibitory activity by binding to a neuronal receptor complex containing the N...
بهمنظور ارزیابی اثر عصاره آبی آلوئهورا (Aloe vera L.) در حیات سلولهای عصبی حرکتی، بیان گیرنده مرگ (P75NTR و نوروتروفینمنتج از مغز) BDNF مورد بررسی قرار گرفت. 24 موش بزرگ بالغ ماده نژاد اسپراگ داولی از انستیتو رازی تهیه شد. حیوانات به 4 گروه: 1- لامینکتومی (مهره 11-9 پشتی) و تزریق عصاره آبی آلوئهورا، 2- لامینکتومی و تزریق عصاره آبی آلوئهورا به همراه فشار بر نخاع، 3- لامینکتومی و تزریق سرم ف...
Cholinergic neurons innervating cortical structures are among the most affected neuronal populations in Alzheimer's disease. In rodents, they express high levels of the neurotrophin receptor p75NTR. We have analyzed cholinergic septohippocampal neurons of the medial septal nucleus in p75exonIII (partial p75NTR knock-out) and p75exonIV (complete p75NTR knock-out) mice, in their original genetic ...
Selection of human p75NTR tag SNPs and its biological significance for clinical association studies.
To select tag single nucleotide polymorphisms (SNPs) within and around human p75 neurotrophin receptor (p75NTR) gene in Chinese Han population, the sequence involving p75NTR gene as well as the upstream and downstream of the gene was identified according to the data from National Center for Biotechnology Information (NCBI) GenBank database, and the SNP genotype data involving 63 SNPs in the reg...
Neuroprotective therapies which focus on factors leading to retinal ganglion cells (RGCs) degeneration have been drawing more and more attention. The beneficial effects of nerve growth factor (NGF) on the glaucoma have been recently suggested, but its effects on eye tissue are complex and controversial in various studies. Recent clinical trials of systemically and topically administrated NGF de...
