While adeno-associated virus (AAV)-mediated gene transfer can correct retinal pigment epithelium (RPE) defects in animal models, approaches for the correction of photoreceptor-specific diseases are less efficient. We evaluated the ability of novel AAV serotypes (AAV2\/7, AAV2\/8, AAV2\/9, AAV2rh.43, AAV2rh.64R1, and AAV2hu.29R) in combination with constitutive or photoreceptor-specific promoters to improve photoreceptor transduction, a limiting step in photoreceptor rescue. Based on a qualitative analysis, all AAV serotypes tested efficiently transduce the RPE as well as rod and cone photoreceptors after subretinal administration in mice. Interestingly, AAV2\/9 efficiently transduces Mu\u0308ller cells. To compare photoreceptor transduction from different AAVs and promoters in both a qualitative and quantitative manner, we designed a strategy based on the use of a bicistronic construct expressing both enhanced green fluorescent protein and luciferase. We found that AAV2\/8 and AAV2\/7 mediate six- to eightfold higher levels of in vivo photoreceptor transduction than AAV2\/5, considered so far the most efficient AAV serotype for photoreceptor targeting. In addition, following subretinal administration of AAV, the rhodopsin promoter allows significantly higher levels of photoreceptor expression than the other ubiquitous or photoreceptor-specific promoters tested. Finally, we show that AAV2\/7, AAV2\/8, and AAV2\/9 outperform AAV2\/5 following ex vivo transduction of retinal progenitor cells differentiated into photoreceptors. We conclude that AAV2\/7 or AAV2\/8 and the rhodopsin promoter provide the highest levels of photoreceptor transduction both in and ex vivo and that this may overcome the limitation to therapeutic success observed so far in models of inherited severe photoreceptor diseases.<\/jats:p>","DOI":"10.1128\/jvi.01327-07","type":"journal-article","created":{"date-parts":[[2007,8,16]],"date-time":"2007-08-16T00:18:25Z","timestamp":1187223505000},"page":"11372-11380","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":230,"title":["Novel Adeno-Associated Virus Serotypes Efficiently Transduce Murine Photoreceptors"],"prefix":"10.1128","volume":"81","author":[{"given":"Mariacarmela","family":"Allocca","sequence":"first","affiliation":[{"name":"Telethon Institute of Genetics and Medicine (TIGEM), Naples, Italy"},{"name":"SEMM, European School of Molecular Medicine, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Mussolino","sequence":"additional","affiliation":[{"name":"Telethon Institute of Genetics and Medicine (TIGEM), Naples, Italy"},{"name":"SEMM, European School of Molecular Medicine, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Garcia-Hoyos","sequence":"additional","affiliation":[{"name":"Telethon Institute of Genetics and Medicine (TIGEM), Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Sanges","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, University of Modena and Reggio Emilia, Reggio Emilia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Iodice","sequence":"additional","affiliation":[{"name":"Telethon Institute of Genetics and Medicine (TIGEM), Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Petrillo","sequence":"additional","affiliation":[{"name":"Telethon Institute of Genetics and Medicine (TIGEM), Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luk H.","family":"Vandenberghe","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of Pennsylvania School of Medicine, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James M.","family":"Wilson","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of Pennsylvania School of Medicine, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valeria","family":"Marigo","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, University of Modena and Reggio Emilia, Reggio Emilia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrico M.","family":"Surace","sequence":"additional","affiliation":[{"name":"Telethon Institute of Genetics and Medicine (TIGEM), Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Auricchio","sequence":"additional","affiliation":[{"name":"Telethon Institute of Genetics and Medicine (TIGEM), Naples, Italy"},{"name":"Medical Genetics, Department of Pediatrics, Federico II University, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ymthe.2005.08.008"},{"key":"e_1_3_2_3_2","first-page":"92","volume":"28","year":"2001","unstructured":"Acland, G.
