Because of AAV's specialized gene therapy advantages, researchers have created an altered version of AAV termed self-complementary adeno-associated virus (scAAV). Whereas AAV packages a single strand of DNA and must wait for its second strand to be synthesized, scAAV packages two shorter strands that are complementary to each other.
Self-complementary adeno-associated virus (scAAV) is a viral vector engineered from the naturally occurring adeno-associated virus (AAV) to be used as a tool for gene therapy. [1] Use of recombinant AAV (rAAV) has been successful in clinical trials addressing a variety of diseases. [ 2 ]
One disadvantage is that they are not able to carry large amounts of foreign genetic materials. Furthermore, the need to express the complementary strand for its single-stranded genome may delay transgene expression. [45] As of 2020, 11 different AAV serotypes—differing by capsid structure and consequently by tropism—had been identified. [43]
AAV is capable of transducing multiple cell types within the retina. AAV serotype 2, the most well-studied type of AAV, is commonly administered in one of two routes: intravitreal or subretinal. Using the intravitreal route, AAV is injected in the vitreous humor of the eye. Using the subretinal route, AAV is injected underneath the retina ...

Strasbourg (France), Berlin (Germany), November 5, 2024, 7:30 a.m. CET—Transgene (Euronext Paris: TNG), a biotech company that designs and develops virus-based immunotherapies for the treatment of cancer, and ProBioGen, a leading CDMO in biologics, vaccines and viral vectors, announce that the companies have entered into a license agreement for ProBioGen’s AGE1.CR.pIX® suspension cell line.
After months of more mild cases, the bird flu appears to be ramping up: The U.S. just saw its first death from the virus, and cases have been found in birds across all 50 states, according to the ...
AAV persists within the cell outside of the cell's nuclear genome for an extended period of time through the formation of concatemers mostly organized as episomes. [77]: 4 Genetic material from AAV vectors is integrated into the host cell's nuclear genome at a low frequency and likely mediated by the DNA-modifying enzymes of the host cell.
