Abstract: Model systems of Alzheimer's disease comprise a DNA sequence encoding an amyloid precursor protein (APP) isoform or fragment that has an amino acid substitution. The substituted amino acid may be other than valine at the amino acid position corresponding to amino acid residue position 717 of APP770. Methods of determining genetic predisposition to Alzheimer's disease are also disclosed.

Abstract: Processing of .beta.-amyloid precursor protein (.beta.APP) is monitored by detecting the secretion of a soluble .beta.APP fragment resulting from cleavage of .beta.APP at the amino-terminus of .beta.-amyloid peptide. In vivo monitoring of secretion of the .beta.APP fragment may be monitored for diagnosis and prognosis of Alzheimer's disease and other .beta.-amyloid-related diseases, while in vitro monitoring of such secretion from cultured cells may be monitored to identify inhibitors of .beta.-amyloid production. The .beta.APP fragment may be detected using antibodies and other specific binding substances which recognize a carboxy-terminal residue on the fragment.
