| abstract |
A transgenic nonhuman animal that expresses the human Apo E isoform Apo E2, Apo E3 or Apo E4 but is essentially incapable of expressing endogenous Apo E. Additionally, animals that express more than one of these isoforms are produced by selectively breeding the transgenic animals expressing the different Apo E isoforms disclosed herein. Thus, the present invention allows, among other things, the study of the effects of different combinations of human Apo E isoform expression on normal brain biology, development, function, ageing and injury. |
