Substitutions at codon 22 of Alzheimer's abeta peptide induce diverse conformational changes and apoptotic effects in human cerebral endothelial cells.

Abstract excerpt

Cerebral amyloid angiopathy is commonly associated with normal aging and Alzheimer's disease and it is also the principal feature of hereditary cerebral hemorrhage with amyloidosis Dutch type, a familial condition associated to a point mutation G to C at codon 693 of the amyloid beta (Abeta) precursor protein gene resulting in a Glu to Gln substitution at position 22 of the Abeta (E22Q). The patients carrying the...
