Abstract:
:The effect of neurotrophic factors on apoptosis induced by ionomycin, a potent Ca2+ ionophore, was investigated using cultured cortical neurons from embryonic rats. Brain-derived neurotophic factor (BDNF) and neurotrophin-3 (NT-3) prevented the ionomycin-mediated cell death in a dose-dependent manner. In contrast to the neurotrophins, cilliary neurotrophic factor (CNTF) did not rescue neurons from cell death induced by ionomycin. The protective effect of BDNF was partially blocked by wortmannin, a phosphatidylinositol 3-kinase inhibitor, and by PD98059, a MAP kinase kinase inhibitor. However, the addition of both compounds together completely inhibited the survival promoting effect of BDNF. These results suggest that the neuroprotective effect of BDNF requires activation of both phosphatidylinositol-3 kinase and the Ras/MAP kinase cascade and that CNTF signaling through other pathways is without an effect in this system.
