| Research Abstract |
In the present research, we have developed a sandwich ELISA specific to Aβ oligomers. The combination of this methodology with size exclusion chromatography allowed us to identify the presence of Aβ oligomers in human cerebrospinal fluid(CSF). It is well known that the levels of Aβ monomers was decreased in the CSF obtained from Alzheimer's disease(AD) compared to age-matched normal subjects. Interestingly, the levels of Aβ oligomers were increased in AD patients with a comcomitant reduction of Aβ monomers. Therefore, it is relevant to note that the measurement of the ratio, Aβ oligomers to monomers, was a potential tool to monitor the Alzheimer's disease. We also found that the administration of melatonin caused the elevation of Aβ in plasma obtained from the model mice of Alzheimer's disease, whch allowed us to see if which mice have an accumulation of Aβ in the brain. Our results may indicate that both could be a potential "surrogate marker" for AD.
