BACKGROUND AND PURPOSE Hypoxia preconditioning (HPC), rapid or delayed, has been reported to induce neuroprotection against subsequent severe stress. Because delta-opioid receptor (DOR) plays an important role in delayed HPC-induced neuroprotection against severe hypoxic injury, we asked whether DOR is also involved in the rapid HPC-induced neuroprotection.(More)
MAP kinase is associated with delta-opioid receptor (DOR) signaling and plays a role in cell survival/death. Since anisomycin may alter MAP kinase activity and affect neuronal survival, we investigated whether anisomycin alters neuronal response to hypoxic stress and DOR inhibition. The experiments were performed in cultured cortical neurons. MAP kinase(More)
Our previous work shows that delta-opioid receptor (DOR) protects cortical neurons from hypoxic insults. Since an enhanced anaerobic capacity is important for neurons to adapt to the reduction of oxidative phosphorylation, we asked whether DOR plays a role in neuronal regulation of anaerobic capacity, thus protecting neurons from O(2) deprivation. Indeed,(More)
