Global Adeno-Associated Virus Vector-Based Gene Therapy Market represents a frontier in medical science, offering the potential to cure genetic disorders by modifying the genetic structure of cells. Among the various vectors used in gene therapy, adeno-associated virus (AAV) vectors have emerged as a promising tool due to their ability to deliver genes safely and effectively. The global adeno-associated virus vector-based gene therapy market is poised for substantial growth, with an expected CAGR of 32.93% during the forecast period of 2024-2032. This growth is driven by the increasing focus on technological advancements in healthcare across the globe, as well as the rising prevalence of genetic disorders.
Market Overview
What is Adeno-Associated Virus Vector-Based Gene Therapy?
Adeno-associated virus (AAV) vectors are small, non-enveloped viruses that have become a preferred delivery method for gene therapy. These vectors are derived from the adeno-associated virus, which is a member of the Parvoviridae family. AAV vectors are particularly favored in gene therapy due to their low immunogenicity, ability to target both dividing and non-dividing cells, and stable long-term expression of the delivered gene.
In gene therapy, AAV vectors are engineered to carry a therapeutic gene into a patient’s cells. Once inside the cells, the gene is expressed, potentially correcting the underlying genetic disorder. This method has shown promise in treating a variety of conditions, including inherited retinal diseases, hemophilia, spinal muscular atrophy, and more.
