The p75 Neurotrophin Receptor


The p75 Neurotrophin Receptor

Clare K Underwood et al. Int J Biochem Cell Biol.


The pan neurotrophin receptor (p75(NTR)) is best known for mediating neural cell death during development as well as in the adult following injury, the latter making it a target for the treatment of neurodegenerative disease. Although p75(NTR) has been studied for over 30 years, a number of recent discoveries have changed our understanding of its regulation. Here we provide a brief overview of the p75(NTR) protein, its post-translational modifications, and the phenotype of p75(NTR)-deficient mice as a starting point for researchers unfamiliar with this complex receptor. The accepted mechanisms underlying the ability of p75(NTR) to regulate cell death as well as a number of other neural functions, most notably neuronal differentiation, neurite outgrowth and synaptic plasticity, are also summarised.
