• PubMed Abstract: 
  

  Adeno-associated virus (AAV) are classified as non-enveloped ssDNA viruses. However, AAV capsids embedded within exosomes have been observed, and it has been suggested that the AAV membrane associated accessory protein (MAAP) may play a role in envelope-associated AAV (EA-AAV) capsid formation. Here, we observed and selected sufficient homogeneous EA-AAV capsids of AAV2, produced using the Sf9 baculoviral expression system, to determine the cryo-electron microscopy (cryo-EM) structure at 3.14 Å resolution. The reconstructed map confirmed that the EA-AAV capsid, showed no significant structural variation compared to the non-envelope capsid. In addition, the Sf9 expression system used implies the notion that MAAP may enhance exosome AAV encapsulation. Furthermore, we speculate that these EA-AAV capsids may have therapeutic benefits over the currently used non-envelope AAV capsids, with advantages in immune evasion and/or improved infectivity.
