Abstract:
The neurotrophins play an important role in the development of the nervous system. These trophic factors affect the cells through the neurotrophin receptors Trk and p75NTR. Trk (tyrosine kinase receptor) mediated signaling promotes survival and growth, while p75NTR-mediated signaling promotes cell death. The structure of p75NTR and its role in the regulation of survival, growth and induction of apoptosis are discussed. p75NTR can interact with the aggregated form of Aβ peptides and by influencing protein tau hyperphosphorylation plays an important role in etiopathogenesis of Alzheimer's disease.

Enzyme-linked Receptors
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
