Targeting gangliosides to treat Alzheimer’s and Parkinson’s diseases:A disruptive approach with the first-in-class peptide AmyP53OA

Neurodegenerative diseases are a growing burden on healthcare systems.Patients with Alzheimer’s or Parkinson’s diseases(AD or PD)are desperately waiting for innovative solutions that are slow to come,despite several decades of research worldwide.In 2021 and again in 2023,two monoclonal antibodies,aducanumab and lecanemab,have been approved by the U.S.Food and Drug Administration,and a third,donanemab,is currently under review.However,these treatments have very limited efficacy on cognitive functions and are accompanied by major side effects:amyloid-related imaging abnormalities,microhemorrhages,and accelerated brain volume loss(Høilund-Carlsen et al.,2024).
