Abstract
The present invention relates to a vector comprising a nucleic acid sequence that encodes the APP protein and/or the PS1 protein or variants thereof. The invention also relates to a method for inducing the Alzheimer's disease in an animal using the vector of the invention and to animal model having the Alzheimer's disease obtained by said method.
Claims12
A method for inducing aspects of Alzheimer's disease in a non-human mammal, said method consisting of co-administering, to the brain of the non-human mammal, a gene encoding Amyloid Precursor Protein (APP) protein and a gene encoding Presenilin 1 (PS1) protein,
- wherein the gene encoding the APP protein and the gene encoding PS1 protein are present in at least one vector, and wherein only the APP protein and the PS1 protein are co-expressible from any of said at least one vector;
- and
- wherein co-expression of said APP and said PS1 in the brain of the non-human mammal results in the non-human mammal exhibiting behavior suggestive of anxiety and lack of long term memory;
- and
- wherein co-expression of said APP and said PS1 in the brain of the non-human mammal leads to production of βAPP and neurotoxic catabolites of βAPP from one month after administration and up until at least 12 months after administration without the appearance of classical AD late symptoms;
- and
- wherein the at least one vector is not AAV9.
A non-human mammal having symptoms of Alzheimer's disease wherein the symptoms of Alzheimer's disease are induced by a method consisting of
- administering to the non-human mammal at least one vector containing a nucleic acid sequence that encodes an APP protein or a variant thereof and a nucleic acid sequence that encodes a PS1 protein or a variant thereof, and wherein only the APP protein and the PS1 protein are co-expressible from any of said at least one vector,
- wherein the at least one vector is not an AAV 9 vector;
- wherein co-expression of said APP and said PS1 in the brain of the non-human mammal results in the non-human mammal exhibiting behavior suggestive of anxiety and lack of long term memory;
- and
- wherein co-expression of said APP and said PS1 in the brain of the non-human mammal leads to production of βAPP and neurotoxic catabolites of βAPP from one month after administration and up until at least 12 months after administration without the appearance of classical AD late symptoms.
