Abstract
Although identified almost 20 years ago, the precise physiological role of the p75 neurotrophin receptor (p75NTR) has remained elusive. Recent studies have revealed that p75NTR is a component of three distinct receptor platforms that bind different ligands and that, under differing circumstances, facilitate cell survival, cell death, or growth inhibition. These recent developments provide new insights into the functions of this enigmatic receptor.
