The model itself
Mice with extra copies of normal gene are generally normal
Mice with truncated gene having termimal 100 aa’s: like Alzheimers
Mice with mutations from early onset version (V177 to A) or other inherited version (K670 to N, M671 to L) have plaques and bodies, but not tangles (??)
Also involved: Apo E4, presenilin 1 & 2
- different alleles change A-beta-4 accumulation
