The relationship between amyloid-beta protein (Abeta) metabolism and Alzheimer's disease is currently poorly understood. While it is well known that the generation of Abeta results from enzymatic cleavage of its parent molecule, the amyloid beta protein precursor (AbetaPP), there is little information available regarding its in vivo clearance. The E4(More)
OBJECTIVE To compare proteins related to Alzheimer disease (AD) in the frontal cortex and cerebellum of subjects with early-onset AD (EOAD) with or without presenilin 1 (PS1) mutations with sporadic late-onset AD (LOAD) and nondemented control subjects. METHODS Immunohistochemistry, immunoblot analysis, and ELISA were used to detect and assess protein(More)
Alzheimer's disease is a progressively dementing illness characterized by the extracellular accumulation and deposition of beta-amyloid. Early onset Alzheimer's disease is linked to mutations in three genes, all of which lead to increased beta-amyloid production. Inflammatory changes and gliosis may also play a role in the disease process, but the(More)
Immunocompetent microglia play an important role in the pathogenesis of Alzheimer's disease (AD). Antimicroglial antibodies in the cerebrospinal fluid (CSF) in clinically diagnosed AD patients have been previously recorded. Here, we report the results of the analysis of the CSF from 38 autopsy cases: 7 with definite AD; 14 with mild and 10 with moderate(More)
