Ginkgo biloba extract improves cognitive function and increases neurogenesis by reducing A β pathology in 5×FAD mice

In this study, different doses of EGb 761 (0, 10, 20, and 30 mg/kg; intraperitoneal injections once every day for four months) were tested on 5×FAD mice. After consecutive 4-month injections, mice were tested in learning memory tasks, Aβ, and neurogenesis in the dentate gyrus (DG) of hippocampus and morphological characteristics of neurons in DG of hippocampus. Results indicated that EGb 761 (20 and 30 mg/kg) ameliorated memory deficits. Further analysis indicated that EGb 761 can reduce the number of Aβ positive signals in 5×FAD mice, increase the number of newborn neurons, and increase dendritic branching and density of dendritic spines in 5×FAD mice compared to nontreated 5×FAD mice. It was concluded that EGb 761 plays a protective role in the memory deficit of 5×FAD mice.PMID:33841671 | PMC:PMC8014356
