Nerve growth factor (NGF) rescues dorsal root ganglion neurons and PC12 cells from cisplatin-induced cell death. Two model systems were used to demonstrate that rescue is mediated through the high affinity NGF receptor. In dorsal root ganglion (DRG) neurons isolated from p75-/- and control mice, 20 ng/ml NGF completely prevented cisplatin-induced death. In PC12 cells, we overexpressed receptor chimeras between the tumor necrosis factor and NGF receptors. We demonstrated that activation of the intracellular domain of Trk A is responsible for the NGF rescue effect.
