phase of their target-directed pathfinding. Results TrkC-Positive DRG Neurons Are Rescued in Bax/NT-3 Double Knockout Mice Mice lacking proapoptotic protein Bax allow for distinguishing survival effects of neurotrophins from other effects. Bax-deficient sensory neurons no longer require neurotrophins for survival (White et al. 1998; Patel et al. 2000), t
