Nerve growth factor (NGF) binding to cellular receptors is required for the survival of some neural cells. In contrast to TrkA, the high-affinity NGF receptor that transduces NGF signals for survival and differentiation, the function of the low-affinity NGF receptor, p75NGFR, remains uncertain. Expression of p75NGFR induced neural cell death constitutively(More)
During development, many neuronal populations undergo a process of normal, programmed cell death, or apoptosis. Trophic factors regulate this process, but the mechanism by which they suppress apoptosis remains unclear. In the immune system, recent studies have implicated the protooncogene bcl-2 in the lymphocyte survival response to growth factors. To(More)
Glutamate has been shown, at high concentrations (5-10 mM), to lead to death in cells of the pheochromocytoma cell line PC12. We report that similar concentrations of glutamate also kill immortalized central neural cell lines, and that the expression of the proto-oncogene bcl-2 in these cell lines blocks glutamate neurotoxicity. Potassium chloride (25 mM)(More)
