- Neuroprotection: Promotes neuronal survival
- Immune Response: Regulates inflammatory gene expression
- MAFB regulates microglial identity
- Controls TREM2 expression
- Modulates neuroinflammation
- MAFB in oligodendrocyte precursor cells
- Myelin repair mechanisms
MAFB is expressed in:
- Microglia
- Oligodendrocytes
- Macrophages
