AAV Capsid-Promoter Interaction Shown to Occur in Non-human Primate Brain
December 11, 2020
The phenomenon of adeno-associated virus (AAV) capsid-promoter interaction recently seen in the rat central nervous system has now been shown to occur in the non-human primate brain. This interaction can directly determine cell-specific transgene expression, as described in the article, “Adeno-Associated Virus Capsid-Promoter Interactions in the Brain Translate from Rat to the Nonhuman Primate,” published in
Human Gene Therapy.
An AAV contains a single-stranded DNA genome encapsulated in a capsid comprised of three structural proteins.
“Recently, we established an AAV9 capsid-promoter interaction that directly determined cell-specific gene expression across two synthetic promoters, Cbh and CBA, in the rat striatum. These studies not only expand this capsid-promoter interaction to include another promoter in the rat striatum but also establish AAV capsid-promoter interactions in the nonhuman primate brain,” the investigators wrote.
