Soluble oligomers and/or aggregates of Amyloid-beta (Abeta) are viewed by many as the principal cause for neurodegeneration in Alzheimer's disease (AD). However, the mechanism by which Abeta and its aggregates cause neurodegeneration is not clear. The toxicity of Abeta has been attributed to its hydrophobicity. Read More

Human and rodent amyloid-beta peptides differentially bind heme: relevance to the human susceptibility to Alzheimer's disease.

Arch Biochem Biophys 2009 Jul 18;487(1):59-65. Epub 2009 May 18.

Amyloid-beta (Abeta) peptides are implicated in the neurodegeneration of Alzheimer's disease (AD). We previously investigated the mechanism of neurotoxicity of Abeta and found that human Abeta (huAbeta) binds and depletes heme, forming an Abeta-heme complex with peroxidase activity. Rodent Abeta (roAbeta) is identical to huAbeta, except for three amino acids within the proposed heme-binding motif (Site-H). Read More
