I. DescriptionI-1. Adeno-Associated VirusAdeno-AssociatedVirus(AAV)isanon-envelopedvirusthatbelongstotheParvovirusfamilyoftheDependovirusgenus.AAVisnotthoughttobepathogenictohumansandonlyreplicatesinthepresenceofahelpervirus,suchasadenovirusorherpesvirus.TheAAVgenomeisalinear,single-strandDNAmoleculeofapproximately4.7kbthathasterminalhairpinstructurescalledinvertedterminalrepeats(ITRs)atbothends.ITRsfunctionasoriginsofgenomicreplicationandcontributetopackagingofviralparticles.TheAAVgenomeincludesthreeopenreadingframes(Figure1):Rep,whichencodesaproteininvolvedinreplicationandtranscription;Cap,whichencodescapsidproteins;andAAP,whichencodesanon-structuralproteinnecessaryforformationofviralparticles.TheRepregioncodesfor4differentproteins(Rep78,Rep68,Rep52,andRep40),andtheCapregioncodesfor3differentproteins(VP1,VP2,andVP3).

Therearemorethan100serotypesofAAV,andthehostspecificityandcharacteristicsofthevirusdifferamongserotypes.TaKaRaBioInc.provideskitsforpreparationofAAVserotype1(AAV1),serotype2(AAV2),serotype5(AAV5),andserotype6(AAV6).AAVserotype2(AAV2)isthemostcommonlyusedserotypeinAAV-basedresearch,includinggenetherapy,andischaracterizedbyabroadhostrange.ThetissuehostrangeofAAV1,AAV5,andAAV6arehighlylimited.AAV1hashightransductionefficiencyformuscle,liver,respiratorytract,andcentralnervoussystem.AAV5hashightransductionefficiencyforcentralnervoussystem,liver,andretina.AAV6hashightransductionefficiencyforcardiomyocyte,muscle,andliver.
