Introducing Human APOE into Aβ Transgenic Mouse Models

Table 1

ApoE transgenic models. Summary of the effects induced by deletion of mouse apoE (apo ) or the introduction of h-apoE isoforms on markers of neuronal degeneration and behavior. Key: HC: hippocampus; CX: cortex; DG: dentate gyrus; ChAT: choline acetyl transferase; ICH: intracerebral hemorrhage; LTP: long-term potentiation; TR: targeted replacement (knock-in); F: female; M: male; m: month.
