Possible involvement of advanced glycation end-products (AGEs) in the pathogenesis of Alzheimer's disease
Takeuchi M, Yamagishi S.. Current pharmaceutical design, 2008-01-01
Topic: Amyloid, tau and blood-test diagnosis
Alzheimer's disease (AD) is the most common cause of dementia in developed countries. AD is characterized pathologically by the presence of senile plaques (SPs) and neurofibrillary tangles (NFTs), the major constituents of which are amyloid betaprotein and tau protein, respectively. Advanced glycation end-products (AGEs), senescent macroprotein derivatives formed at an accelerated rate under normal aging, can be identified immunohistochemically in both SPs and NFTs in AD patients. Further, recent clinical evidence has suggested diabetes mellitus as one of the risk factors for the development and progression of AD. Continuous hyperglycemia is a causative factor for diabetic vascular complications, and it enhances the generation of AGEs through the non-enzymatic glycation, thereby being involved in the pathogenesis of AD as well. Moreover, there is a growing body of evidence to show that the interaction of AGEs with a receptor for AGEs (RAGE) elicits reactive oxygen species generation and vascular inflammation, and subsequently alters various gene expressions in numerous types of cells, all of which could contribute to the pathological changes of diabetic vascular complications and AD. Indeed, we have recently found that glyceraldehyde-derived AGEs (Glycer-AGE) induce apoptotic cell death in cultured cortical neuronal cells. In addition, we also found that neurotoxic effect of diabetic serum on neuronal cells was blocked by neutralizing antibody raised against Glycer-AGE. In human AD brains, Glycer-AGE are actually detected in the cytosol of neurons in the hippocampus and para-hippocampal gyrus. These observations suggest that Glycer-AGE play a role in the pathogenesis of AD. In this review, we discuss the pathophysiological role for AGEs in the development and progression of AD, especially focusing on Glycer-AGE.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
