Among the most promising approaches for treating Alzheimer´ s disease is immunotherapy
with amyloid-β (Aβ)-targeting antibodies. Using in vivo two-photon imaging in mouse
models, we found that two different antibodies to Aβ used for treatment were ineffective at
repairing neuronal dysfunction and caused an increase in cortical hyperactivity. This
unexpected finding provides a possible cellular explanation for the lack of cognitive
improvement by immunotherapy in human studies.
