The construction of transgenic animal models of human Alzheimer's disease, and methods of using the models to screen potential Alzhe## disease therapeutics, are described. The models are characterized by pathologies similar to pathologies observed in Alzheimer's disease, based on expression of all three forms of the β-amyloid precursor protein (APP), APP695, APP751, and APP770, as well as various point mutations based on naturally occurring mutations, such as the London and Indiana familial Alzheimer's disease (FAD) mutations at amino acid 717, predicted mutations in the APP gene, and truncated forms of APP that contain the Aβ region.

Huntington's Disease (HD) is an autosomal-dominant inherited progressive neurodegenerative disease from the group of CAG repeat / polyglutamine diseases and is characterized by a triad of psychiatric alterations, dementia and motor dysfunction. On a sub-cellular level, a mutation with extended CAG tri-nucleotide repeats has been identified as the cause of HD. The therapeutic effects of certain substances can be tested on neurotoxically-induced or transgenic animal models with expanded CAG-repeats. In the present invention, transgenic rats were generated and characterized for human HD. Said rat model for human HD and other diseases of the CNS carries 51 CAG repeats under the control of a rat promoter and has a slow progressive neurological phenotype, closely reflecting human HD syndrome. The comparability of the rat model in relation to human HD is characterized by neuropathological, neuroradiological and neurochemical modifications accompanied by typical behavioral symptoms.
