AdV

Adenoviruses (members of the family Adenoviridae) are medium-sized (90-100 nm), nonenveloped (without an outer lipid bilayer) viruses with an icosahedral nucleocapsid containing a double stranded DNA genome. Their name derives from their initial isolation from human adenoids in 1953. Over 40 types of adenoviruses have currently been recognized. Adenoviruses have long been a popular viral vector for gene therapy due to their ability to affect both replicating and non-replicating cells, accommodate large transgenes, and code for proteins without integrating into the host cell genome. More specifically, they are used as a vehicle to administer targeted therapy, in the form of recombinant DNA or protein. This therapy has been found especially useful in treating cystic fibrosis.
