title: Going the distance, or not, with neurotrophin signals.
abstract: NGF and NT-3 both signal through TrkA receptors on the axons of developing sympathetic neurons, but while NGF supports survival and differentiation, NT-3 does not. In this issue of Cell, the difference is explained as the ability of NGF, but not NT-3, to induce internalization and retrograde transport of activated TrkA.
