Outline of therapeutic agents for targeting APOE4 for Alzheimer’s disease.
| Therapeutic strategies | Principle | Studies | References | Animal models | Humans |
| RXR, LXR, PPARγ agonists | Increases the lipidation of APOE and promotes Aβ clearance | Mouse | Yes | [75–90, 91, 98] | Anti-APOE4 monoclonal antibody | Increases amyloid clearance and decreases APOE-associated toxic effects | | Yes | [99–102, 122, 196] | Small peptides comprising the receptor-binding region in APOE | Reduces inflammation and neurotoxicity, increases APOE3-linked protective functions | Mouse | No | [123, 132, 133, 197, 198] | Small molecules | Increases Aβ clearance, APOE signaling, and cholesterol transport | Mouse | No | [175, 176] | APOE4 structure correctors (GIND25 and PH002) | Interferes with domain-domain interaction in APOE4 thus reducing its toxic effects | | No | [145–147] | Viral-mediated APOE2 expression | Enhances APOE-connected neurodefensive effects | Mouse | Yes | [166, 169, 199] | Aβ12-28P, Aβ20-29 peptide, small-molecule inhibitors | Increases amyloid clearance | Mouse | No | [153–157] | Cyclosporine A | Decreases leakage of blood-derived toxic molecules in APOE4-carrying brain | Mouse | Yes | [179, 200] |
