Typical Promoter Types Used to Drive Expression in Lentiviral Vectors in the CNS
| Promoter | Strength | Cell Type |
|---|---|---|
| CMV | Strong but subject to transcriptional silencing over time | Ubiquitous |
| PGK | Strong | Ubiquitous |
| EF1-α | Strong | Ubiquitous |
| TRE | Strong, inducible by ttA or ttS+/−Dox, respectively | Ubiquitous |
| GFAP | Moderate-strong | Astrocytes |
| CaMKII | Strong | Postnatal neurons (strong after week 4–5 in mice and rats) |
| Synapsin I | Moderate-strong | Developing neurons (weaker after week 4–5 in mice and rats) |
| Thy-1,2 | Moderate-strong | Prenatal and postnatal neurons |
Cytomegalovirus (CMV); phosphoglycerate kinase 1 promoter, (PGK); Human elongation factor-1 alpha promoter, (EF1-α); The tetracycline response element-containing promoter, (TRE); Glial fibrillary acidic protein promoter, (GFAP); α-calcium/calmodulin-dependent protein kinase II, (CaMKII); Synapsin type I promoters, (Synapsin I); thymocyte differentiation antigen 1 and 2 promoter, (Thy-1,2).
