Beta-amyloid(1-42) induces neuronal death through the p75 neurotrophin receptor.
Alzheimer's disease is characterized by the accumulation of neurotoxic amyloidogenic peptide Abeta, degeneration of the cholinergic innervation to the hippocampus (the septohippocampal pathway), and progressive impairment of cognitive function, particularly memory. Abeta is a ligand for the p75 neurotrophin receptor (p75(NTR)), which is best known for mediating neuronal death and has been consi...
متن کاملTRAF6 and p62 inhibit amyloid β-induced neuronal death through p75 neurotrophin receptor.
Amyloid β (Aβ) aggregates are the primary component of senile plaques in Alzheimer disease (AD) patient's brain. Aβ is known to bind p75 neurotrophin receptor (p75(NTR)) and mediates Aβ-induced neuronal death. Recently, we showed that NGF leads to p75(NTR) polyubiquitination, which promotes neuronal cell survival. Here, we demonstrate that Aβ stimulation impaired the p75(NTR) polyubiquitination...
متن کاملp75 neurotrophin receptor mediates neuronal cell death by activating GIRK channels through phosphatidylinositol 4,5-bisphosphate.
The pan neurotrophin receptor p75(NTR) signals programmed cell death both during nervous system development and after neural trauma and disease in the adult. However, the molecular pathways by which death is mediated remain poorly understood. Here, we show that this cell death is initiated by activation of G-protein-coupled inwardly rectifying potassium (GIRK/Kir3) channels and a consequent pot...
متن کاملChopper, a new death domain of the p75 neurotrophin receptor that mediates rapid neuronal cell death.
The cytoplasmic juxtamembrane region of the p75 neurotrophin receptor (p75(NTR)) has been found to be necessary and sufficient to initiate neural cell death. The region was named "Chopper" to distinguish it from CD95-like death domains. A 29-amino acid peptide corresponding to the Chopper region induced caspase- and calpain-mediated death in a variety of neural and non-neural cell types and was...
متن کاملAbeta(1-42) stimulates adult SVZ neurogenesis through the p75 neurotrophin receptor.
The generation of amyloid-beta peptide (Abeta) and its accumulation in amyloid plaques are generally recognized as key characteristics of Alzheimer's disease. A number of reports have indicated that Abeta can regulate the proliferation of neural precursor cells and adult neurogenesis, suggesting that this may underpin the cognitive decline and compromised olfaction also associated with the cond...
