Abstract :
Gene therapy includes the application of various viral vectors, which represent most types and families of viruses, suitable for infection of mammalian host cells. Both hereditary diseases and acquired illnesses, such as cancer, can be targeted. Because of the various properties of each viral vector, the definition of their application range depends on factors such as packaging capacity, host range, cell- or tissue-specific targeting, replication competency, genome integration and duration of transgene expression. Recent engineering of modified viral vectors has contributed to improved gene delivery efficacy.
