Our review on p75 neurotrophin signaling in nervous system injury has been made available as a paper in press in the Trends In Neurosciences web site.
Injury or insult to the adult nervous system often results in reactivation of signaling pathways that are normally only active during development. The p75 neurotrophin receptor (p75NTR) is one such signaling molecule whose expression increases markedly following neural injury in many of the same cell types that express p75NTR during development. A series of studies during the past decade has demonstrated that p75NTR signaling contributes to neuronal and glial cell damage, axonal degeneration and dysfunction during injury and cellular stress. Why the nervous system reacts to injury by inducing a molecule that aids the demise of cells and axons is a biological paradox that remains to be explained satisfactorily. On the other hand, it may offer unique therapeutic opportunities for limiting the severity of nervous system injury and disease.
