adeno-associated virus

Also found in: Acronyms, Encyclopedia, Wikipedia.


A genus of small defective single-stranded DNA viruses in the family Parvoviridae that depend on adenoviruses for replication.
[L. dependeo, to be dependent upon, + virus]

Adeno-Associated Virus

A member of the parvovirus family, which is composed of small viruses with a genome of a single-stranded DNA. AAVs insert genomic material at a specific site on human chromosome 19 with nearly 100% certainty, and are used to construct vectors that introduce genes into cultured cells. There is virtually no downside to AAV vectors, given the small amount of DNA they can carry and because AAV is non-pathogenic (most people are AAV carriers). In contrast to adenoviruses, AAV usually does not trigger an immune response to cells infected with it, and thus can deliver genes to sites of interest, including the brain in the context of gene therapy for diseases of muscle and eye, tissues where AAV seems to be most useful.

adeno-associated virus

a replication-defective, single-stranded DNA virus classifed in the genus Dependovirus of the family Parvoviridae. They depend on help provided by coinfection with adenoviruses for their replication. Not known to cause disease.
