What types of viruses are commonly used as vectors?

FAQs об исследованиях
Viruses are highly diverse, and are classified based on genome nucleic acid type, strandedness, sense, and method of replication. Not all virus classes are well suited for use as viral vectors, but several types have gained widespread usage in biological research. Retroviruses and lentiviruses provide high-efficiency stable transfection potential, but can induce mutagenesis and require greater safety considerations.1-3 Herpes simplex viruses (HSVs) are popular for neurological studies because of their innate predilection for neuronal infection.4 Finally, adenoviruses and adeno-associated viruses (AAVs) combine high infectiousness with low safety risk, but are highly immunogenic – limiting transduction efficacy.5,6
