p 75 NTR - The Promiscuous Receptor
نویسنده
چکیده
The p75 neurotrophin receptor (p75NTR) could bind a variety of proteins all with biological significance. While this receptor has no catalytic activities, and therefore influences cellular outcomes through protein-protein interactions, how it controls one cellular event over another remains to be deciphered. Alomone Labs offers a broad range of p75NTR related products, ranging from monoclonal to both fluorescently labeled monoclonal and polyclonal antibodies. This report aims at illustrating how these products have influenced p75NTR-related research.

Deprenyl changes the expression of Trk-B and P75 NTR receptors in rat after sciatic nerve axotomy
During development many of neurons die by the phenomenon named programmed cell death or apoptosis and this reaction is regulated by neurotrophin (BDNF, NGF, NT3 and NT4/5). These neurotrophins bind to two different classes of transmembrane receptor proteins, the Trks and P75 NTR. Axotomy can induce apoptosis after birth and deprenyl is a an inhibitor of monoamineoxidase type-B and seems to act ...
متن کاملAmyloid beta binds trimers as well as monomers of the 75-kDa neurotrophin receptor and activates receptor signaling.
p75(NTR), a nerve growth factor co-receptor that has been implicated in apoptosis of neurons, is structurally related to Fas and the receptors for tumor necrosis factor-alpha that display ligand independent assembly into trimers. Using embryonic day 17 fetal rat cortical neurons and p75(NTR)-expressing NIH-3T3 cells, we now show that p75(NTR) exists as a trimer as well as a monomer. Furthermore...

متن کامل-Amyloid to the p75 Neurotrophin Receptor Induces Apoptosis A Possible Mechanism for Alzheimer’s Disease
Alzheimer’s disease is a neurodegenerative disorder characterized by the extracellular deposition in the brain of aggregated b -amyloid peptide, presumed to play a pathogenic role, and by preferential loss of neurons that express the 75-kD neurotrophin receptor (p75 NTR ). Using rat cortical neurons and NIH-3T3 cell line engineered to stably express p75 NTR , we find that the b -amyloid peptide...
متن کاملThe extracellular domain of p75NTR is necessary to inhibit neurotrophin-3 signaling through TrkA.
The TrkA receptor is activated primarily by nerve growth factor (NGF), but it can also be activated by high concentrations of neurotrophin 3 (NT-3). The pan-neurotrophin receptor p75(NTR) strongly inhibits activation of TrkA by NT-3 but not by NGF. To examine the role of p75(NTR) in regulating the specificity of TrkA signaling, we expressed both receptors in Xenopus oocytes. Application of NGF ...
