Disease Modifying Therapies for Alzheimer's Disease Targeting Aβ Oligomers: Implications for Therapeutic Mechanisms

Abstract EN

Several lines of evidence indicate that amyloid β (Aβ), particularly Aβ oligomers (AβOs), plays a causative role in Alzheimer's disease.

However, the mechanisms underlying the action of an anti-AβO antibody to clarify the toxic action of AβOs remain elusive.

Here, we showed that the anti-AβO antibody (monoclonal 72D9) can modify the Aβ aggregation pathway.

We also found that 72D9 directly sequesters both extracellular and intraneuronal AβOs in a nontoxic state.

Thus, therapeutic intervention targeting AβOs is a promising strategy for neuronal protection in Alzheimer's disease.
