Chronic treatment of exendin-4 affects cell proliferation and neuroblast differentiation in the adult mouse hippocampal dentate gyrus

▶ Treatment with exendin-4 increased cell proliferation in the mice subgranular zone. ▶ Treatment with exendin-4 increased neuroblast differentiation in the subgranular zone. ▶ Exendin-4 promotes structural plasticity in the dentate gyrus.
