Adeno-Associated Virus (AAV) has emerged as a prominent tool for gene delivery in therapeutic applications. Its non-pathogenic nature, low immunogenicity, and capacity for long-term expression make it an ideal candidate for addressing various medical challenges, including neurodegenerative disorders, hereditary conditions, and cancers. However, the complexities involved in optimizing AAV vectors pose significant hurdles in their development and application.
AAV Overview
AAV is a member of the Parvoviridae family, characterized by its non-enveloped, single-stranded DNA structure. With a diameter of approximately 26nm and a genome size around 4.7kb, AAV utilizes Inverted Terminal Repeat (ITR) sequences for replication and packaging. The viral genome includes critical open reading frames necessary for replication and capsid formation. Currently, a range of AAV serotypes exists, each with specific receptor affinities, allowing for targeted delivery to various tissues, enhancing the efficacy of gene therapies.
