Amyloid-β: a chameleon walking in two worlds: a review of the trophic and toxic properties of amyloid-β

CS Atwood, ME Obrenovich, T Liu, H Chan… - Brain Research …, 2003 - Elsevier
Although much maligned, the amyloid-β (Aβ) protein has been shown to possess a number
of trophic properties that emanate from the protein's ability to bind Cu, Fe and Zn. Aβ …

Amyloid-β: an antioxidant that becomes a pro-oxidant and critically contributes to Alzheimer's disease

A Kontush - Free Radical Biology and Medicine, 2001 - Elsevier
Elevated production of amyloid-β (Aβ) as a preventive antioxidant for brain lipoproteins

β‐Amyloid neurotoxicity in vitro: evidence of oxidative stress but not protection by antioxidants

CJ Pike, N Ramezan‐Arab… - Journal of …, 1997 - Wiley Online Library
Recent data from several groups suggest that the primary mechanism of β‐amyloid
