The Diabetes Drug Liraglutide Prevents Degenerative Processes in a Mouse Model of Alzheimer's Disease

Liraglutide treatment reduced β-amyloid plaque counts in the cortex by 40-50% in an Alzheimer mouse model.

• In an Alzheimer mouse model, liraglutide was effective in preventing memory impairments during object recognition and water maze tasks.
• The treatment preserved synapse integrity and synaptic plasticity in the hippocampus, which are typically compromised in this model.
• Liraglutide administration resulted in a 25% reduction in levels of soluble amyloid oligomers.
• The number of activated microglia, indicating inflammation, was halved in liraglutide-treated APP/PS1 mice.
• Increased numbers of young neurons were observed in the dentate gyrus of treated APP/PS1 mice.
• Liraglutide had minimal impact on the behavior of wild-type control mice, but it enhanced synaptic plasticity within this group.
