ハントカジノ 銀行振込s a novel diagnostic blood marker of Alzheimer's disease
November 5,2019
Currently, best-characterized indicators for Alzheimer's disease (AD) diagnosis are the decreased levels of amyloid β-protein 42 and increased levels of phosphorylated tau in cerebrospinal fluid (CSF). The positron emission tomography (PET) imaging with Pittsburgh compound B (PiB) is also used in AD diagnosis by visualizing amyloid deposition in the brain. Because these methods are invasive or expensive, less invasive and easily detectable blood biomarkers are required. Because our previous study showed that flotillin release, a marker of exosomes, was attenuated by Aβ, we designed a present study to determine whether ハントカジノ 銀行振込evel could be reduced in CSF and/or serum of patients with AD.
In this study, we analyzed ハントカジノ 銀行振込evels in CSF and serum of non-AD controls, patients with AD and mild cognitive impairment (MCI) by western blotting. ハントカジノ 銀行振込evels in cerebroventricular fluid (CVF) and serum of AD, vascular dementia (VD), and non-AD autopsy cases are also analyzed. ハントカジノ 銀行振込evels significantly decreased in the CSF and serum of AD patients compared with those of non-AD controls, respectively. Moreover, in patients with MCI due to AD determined by PiB-PET, CSF and serum ハントカジノ 銀行振込evels significantly decreased compared with those of patients with MCI due to non-AD. ハントカジノ 銀行振込evels remained unchanged in CVF and serum of autopsy cases diagnosed as VD. Serum ハントカジノ 銀行振込evel is negatively associated with brain amyloid deposition indicated as PiB uptake. These results demonstrate that serum ハントカジノ 銀行振込evel can serve as one of the blood markers for estimation of brain amyloid deposition and early diagnosis of AD.

Figure 1) Serum ハントカジノ 銀行振込evels in patients with AD were lower than those in non-AD cases.
ハントカジノ 銀行振込n serum collected from patients with AD and non-AD cases was examined by western blot analysis. Intensity of flotillin bands was quantified using Image J. A, The representative results analyzed by western blot are shown. B, The quantitative analysis was performed and relative value of intensity of each band was normalized by the average value of ハントカジノ 銀行振込n patients with non-AD as 1. Non-AD group, n=15; AD group, n=15. Data are mean ± S.E.M. Statistical analysis was performed by ANOVA.
Figure 2) Serum ハントカジノ 銀行振込evels in autopsy cases with AD were lower than those in cases with vascular dementia (VD).
Western blot analysis of serum obtained from autopsy cases with AD and VD was performed according to the methods described in the Methods section. A, Representative Western blot of ハントカジノ 銀行振込n serum from the autopsy cases with AD and VD. B, The intensities of flotillin bands were measured using Image J and the intensity of each band was normalized by the average value of samples from cases with VD as 1. The serum flotillin levels significantly decreased in cases with AD compared with cases with VD. VD group, n=17; AD group, n=20. Data are mean ± S.E.M. Statistical analysis was performed by ANOVA.
