What types of viruses are used in gene therapy?

Dr. Jeanne Morrison, PhD
Family Practitioner

Many gene therapy clinical trials rely on retroviruses to deliver the desired gene. Other viruses used as vectors include adenoviruses, adeno-associated viruses, lentiviruses, poxviruses, and herpes viruses. These viruses differ in how well they transfer genes to the cells they recognize and are able to infect, and whether they alter the cell's DNA permanently or temporarily. Thus, researchers may use different vectors, depending on the specific characteristics and requirements of the study.
