A1 Bothwell, Mark YR 2008 UL http://stke.sciencemag.org/content/1/47/pe50.abstract AB The functions of the 75-kilodalton neurotrophin receptor p75NTR have remained enigmatic despite nearly three decades of study. Recent studies reveal that p75NTR is a versatile co-receptor that controls signaling by receptors for multiple ligands that provide repellant guidance cues to developing axons.
