PG - 8512 LID - 10.1038/s41598-019-44739-6 [doi] LID - 8512 AB - Brain-derived neurotrophic factor (BDNF) plays crucial roles in memory impairments including Alzheimer's disease (AD). Previous studies have reported that tetrasialoganglioside GQ1b is involved in long-term potentiation and cognitive functions as well as BDNF expression. However, in vitro and in vivo functions of GQ1b against AD has not investigated yet. Consequently, treatment of oligomeric Abeta followed by GQ1b significantly restores Abeta(1-42)-induced cell death through BDNF up-regulation in primary cortical neurons. Bilateral infusion of GQ1b into the hippocampus ameliorates cognitive deficits in the triple-transgenic AD mouse model (3xTg-AD). GQ1b-infused 3xTg-AD mice had substantially increased BDNF levels compared with artificial cerebrospinal fluid (aCSF)-treated 3xTg-AD mice. Interestingly, we also found that GQ1b administration into hippocampus of 3xTg-AD mice reduces Abeta plaque deposition and tau phosphorylation, which correlate with APP protein reduction and phospho-GSK3beta level increase, respectively. These findings demonstrate that the tetrasialoganglioside GQ1b may contribute to a potential strategy of AD treatment.
