Trem2 Variants In Alzheimer'S Disease represents an important genetic factor in neurodegenerative disease research. This page provides comprehensive information about its role in disease mechanisms, genetic associations, and therapeutic implications. [1]
TREM2 (Triggering Receptor Expressed on Myeloid Cells 2) variants are significant genetic risk factors for late-onset Alzheimer's disease, implicating microglia-mediated immune responses in AD pathogenesis. [2]
| Function | Description | [3]
|----------|-------------| [4]
| Phagocytosis | Clears Aβ plaques, cellular debris |
| Survival | Promotes microglial survival |
| Proliferation | Supports microglial expansion |
| Cytokine production | Regulates inflammatory responses |
| Lipid metabolism | Processes lipids and lipoproteins |
Aβ/Lipids → TREM2 → DAP12 (ITAM) → SYK → PI3K/AKT, MAPK

Many AD-risk variants cause partial loss of function:
TREM2 risk variants impair microglial functions:
| Function | Normal | Risk Variant |
|---|---|---|
| Aβ clearance | Efficient | Reduced |
| Plaque containment | Forms barrier | Fails containment |
| Survival under stress | Robust | Compromised |
| Cytokine regulation | Balanced | Dysregulated |
| Drug | Company | Status |
|---|---|---|
| AL002 | Alector/GSK | Phase 2 |
| AL003 | Alector | Preclinical |
| PRT-A | Promising | Research |
Approach: Deliver functional TREM2
Challenge: Achieving microglial expression
