1 Dehydroepiandrosterone administration improves memory deficits following transient brain ischemia through sigma-1 receptor stimulation. Dehydroepiandrosterone sigma non-opioid intracellular receptor 1 Mus musculus
2 Since DHEA is the endogenous ligand for the sigma-1 receptor (sigma1R), we determined whether oral DHEA administration prevents neuronal cell death and improves cognition via sigma1R stimulation in brain ischemia using a 20-min bilateral common carotid artery occlusion (BCCAO) mouse model. Dehydroepiandrosterone sigma non-opioid intracellular receptor 1 Mus musculus
3 Since DHEA is the endogenous ligand for the sigma-1 receptor (sigma1R), we determined whether oral DHEA administration prevents neuronal cell death and improves cognition via sigma1R stimulation in brain ischemia using a 20-min bilateral common carotid artery occlusion (BCCAO) mouse model. Dehydroepiandrosterone sigma non-opioid intracellular receptor 1 Mus musculus
4 Since DHEA is the endogenous ligand for the sigma-1 receptor (sigma1R), we determined whether oral DHEA administration prevents neuronal cell death and improves cognition via sigma1R stimulation in brain ischemia using a 20-min bilateral common carotid artery occlusion (BCCAO) mouse model. Dehydroepiandrosterone sigma non-opioid intracellular receptor 1 Mus musculus
5 Since DHEA is the endogenous ligand for the sigma-1 receptor (sigma1R), we determined whether oral DHEA administration prevents neuronal cell death and improves cognition via sigma1R stimulation in brain ischemia using a 20-min bilateral common carotid artery occlusion (BCCAO) mouse model. Dehydroepiandrosterone sigma non-opioid intracellular receptor 1 Mus musculus
6 Moreover, DHEA administration significantly ameliorated decreases in adenosine 5"-triphosphate (ATP) levels and decreased sigma1R expression levels in CA1 following BCCAO ischemia. Dehydroepiandrosterone sigma non-opioid intracellular receptor 1 Mus musculus
7 Taken together, DHEA prevents neuronal cell death and activates CaMKII via sigma1R stimulation, thereby improving cognitive deficits following brain ischemia. Dehydroepiandrosterone sigma non-opioid intracellular receptor 1 Mus musculus
