Answer
Each viral vector system has different strengths depending on the application:
-
AAV: low immunogenicity, long-term expression in many systems; limited packaging capacity (~4.7 kb)
-
Lentivirus: stable long-term expression due to integration; risk of insertional mutagenesis; generally better for dividing cells
-
Adenovirus: high transduction efficiency and larger payload; typically transient expression and higher immune response
-
Retrovirus: stable integration but usually limited to dividing cells
The best choice depends on target cells, expression duration, payload size, and safety requirements.
