Background: AAV4 VP3

Adeno-associated virus (AAV) is a small, non-enveloped single-stranded DNA virus belonging to the Pavoviridae family in the genus Dependoparvovirus, which requires a helper virus in order to replicate (1-3). The AAV genome consists of a rep and cap gene which are flanked by inverted terminal repeats (ITRs) (1-4). The rep gene encodes for AAV's non-structural proteins that function in replication, packaging, and integration (2-4). The cap gene encodes the structural proteins (VP1, VP2, VP3) that form the viral capsid made up of 60 protein subunits (2-4). Recombinant AAV vectors are generated by replacing the rep and cap genes and inserting a promoter, followed by a transgene, and then a poly-A (pA) tail, flanked by ITRs (3-4). Recombinant vectors are then packaged by providing the rep and cap genes in trans and helper genes for AAV replication (3). AAV vectors have been studied for their potential in human gene therapy and are considered a safe platform given their low immunogenicity and that they are not associated with any known diseases (1-4). Additionally, recombinant AAV vectors are typically non-integrating (1). There are 13 identified human and non-human primate AAV serotypes and over 100 natural AAV variants (2-4). The AAV serotypes are further classified into six clades (A-F) and two clonal isolates (AAV4 and AAV5) according to the VP1 amino acid (aa) sequence (3). These AAV serotypes share ~65-99% sequence identity and ~95-99% structural identity (3). Research has shown that the different AAV serotypes have varying tissue tropism and transduction efficiency based on tissue origin (2). For instance, AAV8 and AAV9 are optimal for transduction in the liver, while AAV2 is ideal for the kidney (2). AAV2 is the best characterized and most commonly used AAV serotype in preclinical studies and clinical trials (4). AAV vectors have been employed in a number oncology models for their ability to carry and deliver a variety of factors including anti-angiogenic genes, suicide genes, tumor suppressors, cytokines, and monoclonal antibodies (4). Advances in engineering AAV vectors and combining AAV gene delivery with other treatment modalities, like chemotherapeutics, is promising for the future of human gene therapy (2-4).
