p75^NTR known as a cell surface receptor for NGF, BDNF, NT-3 and NT-4, is also a receptor  

for b-amyloid, and for the myelin axon repellant protein MAG.^1,2,4,6 



Binding of neurotrophins induces receptor dimerization followed by phosphorylation of  

receptor kinase residues and recruitment of intracellular proteins involved in signal transduction. 

p75^NTR functions alone, or in functional complexes with the neurotrophin receptors trkA, trkB  

and trkC. p75^NTR signals via interaction with different transducers such as TRAF6, IRAK,  

and RIP-2, activating NF-kappaB, JNK and p38, and inactivating rhoA.^1,3,6 



Receptor degradation is mediated by a metalloproteinase-dependent shedding of the extracellular domain. 

p75^NTR binds all neurotrophins with similar nM affinity, but binds pro-neurotrophins with greater affinity,  

and is more potently activated by pro-neurotrophins.⁵  



Overexpression of the intracellular domain in developing neurons induces apoptosis.  

NGF-dependent association of NRIF with p75^NTR contributes to pro-apoptotic signaling.^7,8 

b-amyloid peptide binds p75^NTR and stimulates pro-apoptotic signaling by p75^NTR,  

suggesting that the receptor may be relevant for Alzheimer's disease.⁹
