Ischemic stroke leads to neuronal damage induced by excitotoxicity, inflammation, and oxidative stress. Astrocytes play diverse roles in stroke and ischemia‐induced inflammation, and autophagy is critical for maintaining astrocytic functions. Our previous studies showed that the activation of G protein‐coupled receptor 30 (GPR30), an estrogen membrane receptor, protected neurons from excitotoxicity...
Astrocytes protect neurons during cerebral injury through several postulated mechanisms. Recent therapeutic attention has focused on enhancing or augmenting the neuroprotective actions of astrocytes but in some instances astrocytes can assume a neurotoxic phenotype. The signaling mechanisms that drive astrocytes toward a protective versus toxic phenotype are not fully known but cell–cell signaling...
