The receptor sortilin has been implicated in pro-apoptotic signaling of proneurotrophins. In this study, the authors uncover another role for sortilin in neurotrophin signaling: it interacts with Trk family receptors to promote their anterograde transport to nerve endings, thereby enhancing neurotrophin-dependent cell survival.
