Abstract:

Alzheimer's Disease (AD) is a neurodegenerative disorder characterized by the β-amyloid (Aβ) peptide accumulation and deposition in the brain. Aβ alterations are thought to take place decades before the appearance of the first signs of dementia: This preclinical phase is considered the most promising period for successful disease-modifying therapies, which are still lacking. Since negatively charged lipids showed high binding affinity toward Aβ peptide and low-density lipoproteinreceptor was observed at the blood-brain barrier, we previously designed liposomes functionalized with phosphatidic acid and with a modified peptide derived from apolipoprotein-E (mApoE-PA-LIP) potentially able to enter the brain and disaggregate Aβ aggregates both in vitro and in vivo. We evaluated the possibility to use mApoE-PA-LIP for treatment of AD on different Tg rodent models of the disease, namely APP/PS1 or APP23 mice. The data obtained in vivo suggest that mApoE-PA-LIP is able either to promote the decrease of brain Aβ burden and the amelioration of memory impairment in �??old�?� Tg mice upon acute treatment, or to slow down brain Aβ accumulation and memory impairment in �??young�?� upon long term treatment. Together, these data indicate mApoE-PA-LIP as a new nanotechnological device potentially suitable for AD treatment.
