doi: 10.1007/s11064-025-04370-6

Figure Lengend Snippet: Schematic diagram illustrating the role of astrocytic GDNF in neuronal survival and brain recovery after ischemic stroke. Astrocytes are activated following ischemic stroke and become reactive astrocytes. Reactive astrocytes release GDNF into extracellular space and binds to GFRα1 protein anchor on neuronal cell membrane. The GDNF-GFRα1 complexes trigger the phosphorylation of RET receptors in neurons and initiate intracellular signaling pathways, which suppress mitochondrial fission and reduce oxidative stress. These changes inhibit caspase regulated cell apoptosis and promote neuronal survival and brain recovery after ischemic stroke
