M P Mattson et al.
The Journal of neuroscience : the official journal of the Society for Neuroscience, 12(2), 376-389 (1992-02-01)
In Alzheimer's disease (AD), abnormal accumulations of beta-amyloid are present in the brain and degenerating neurons exhibit cytoskeletal aberrations (neurofibrillary tangles). Roles for beta-amyloid in the neuronal degeneration of AD have been suggested based on recent data obtained in rodent
P E Fraser et al.
Journal of neuroscience research, 28(4), 474-485 (1991-04-01)
To elucidate the relationship between amyloid fibril formation in Alzheimer disease (AD) and the primary structure of the beta-amyloid protein (beta-AP), we investigated the ability of peptides sharing sequences with beta-AP to form fibrils in vitro and to recognize anti-beta-amyloid
P E Gottschall
Neuroreport, 7(18), 3077-3080 (1996-11-25)
Since administration of anti-inflammatory drugs has been reported to possibly slow the progression of Alzheimer's disease, an effort was made to define effector functions induced by beta-amyloid (A beta) which may be inhibited by these drugs. Rat microglia in culture
