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

Despite the application of amyloid imaging agents such as PIB, SB13, and FDDNP in Alzheimer's disease (AD) patients, the successful use of these agents in transgenic mice models of AD has not been reported to date. As a first step in understanding the behaviour of these ligands in transgenic models of AD, we have investigated in a series of in vitro ligand binding assays the interaction of selected agents, including PIB, FDDNP, SB13, and BSB, with amyloid fibrils produced from rodent Abeta(1-40) (roAbeta) peptide. The data indicate that the ligand binding affinities together with the pattern and number of binding sites on the roAbeta fibrils are broadly conserved with that reported previously for human Abeta(1-40) (huAbeta) fibrils.
