| Outline of Final Research Achievements |
Mild cognitive impairment (MCI) is an early satage of Alzheimer's disease(AD) and diagnosin at this stage is highly desired. Aggregated A-beta is the main pathological feature in AD brain. We showed different behavior of VD 2 and VD3 to A-beta aggregations and suggest that VD2 promote A-beta aggregation and VD3 might inhibit the aggregation in vitro. Based on these obsrvation, we assay serum VD3 concentrations in healthy control and MCI and AD (at different stages by MMSE). Our syudy suggest that 25(OH)VD3, but not 1,25(OH)2VD3, is a useful biomarker for not only AD but also MCI diagnosis, and decrease of serum 25(OH)VD3 concentrations corelate with AD severety. Our study suggest that serum 25(OH)VD3 concentrations could be useful biomarker for prediction and diagnosis of MCI and various stages of AD. THe results support the utility of vitamin D supplementation in AD therapy regimen.
