Amyloid deposition, hypometabolism, and longitudinal cognitive decline.
OBJECTIVE Using data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) population, we examined (1) cross-sectional relationships between amyloid deposition, hypometabolism, and cognition, and (2) associations between amyloid and hypometabolism measurements and longitudinal cognitive measurements. METHODS We examined associations between mean cortical florbetapir uptake, mean (18) F-...
متن کاملReduction of cholesterol synthesis in the mouse brain does not affect amyloid formation in Alzheimer's disease, but does extend lifespan.
Alterations in cellular cholesterol synthesis or content in cultured neurons affect the cleavage of amyloid precursor protein to amyloidogenic Abeta(40) and Abeta(42) peptides characteristic of Alzheimer's disease. To determine whether a decrease in cholesterol synthesis affects amyloid precursor protein processing in vivo, we crossed cholesterol 24-hydroxylase knockout mice, which exhibit a 50...

متن کاملDiverging patterns of amyloid deposition and hypometabolism in clinical variants of probable Alzheimer's disease.
The factors driving clinical heterogeneity in Alzheimer's disease are not well understood. This study assessed the relationship between amyloid deposition, glucose metabolism and clinical phenotype in Alzheimer's disease, and investigated how these relate to the involvement of functional networks. The study included 17 patients with early-onset Alzheimer's disease (age at onset <65 years), 12 p...
متن کاملReplacement of brain-resident myeloid cells does not alter cerebral amyloid-β deposition in mouse models of Alzheimer’s disease
Immune cells of myeloid lineage are encountered in the Alzheimer's disease (AD) brain, where they cluster around amyloid-β plaques. However, assigning functional roles to myeloid cell subtypes has been problematic, and the potential for peripheral myeloid cells to alleviate AD pathology remains unclear. Therefore, we asked whether replacement of brain-resident myeloid cells with peripheral mono...
