Here we constructed a series of recombinant RVs containing mutations within the PPEY motif and analyzed their effects on viral replication and RV pathogenicity. Our results indicate that the first proline at position 35 is the most important for viral replication, whereas P36 and Y38 have a lesser but still noticeable impact. The reduction in viral replication was most likely due to inhibition of virion release, because initially no major impact on RV RNA synthesis was observed. In addition, results from electron microscopy demonstrated that the M4A mutant virus (PPEY\u2192SAEA) displayed a more cell-associated phenotype than that of wild-type RV. Furthermore, all mutations within the PPEY motif resulted in reduced spread of the recombinant RVs as indicated by a reduction in focus size. Importantly, recombinant PPEY L-domain mutants were highly attenuated in mice yet still elicited potent antibody responses against RV G protein that were as high as those observed after infection with wild-type virus. Our data indicate that the RV PPEY motif has L-domain activity essential for efficient virus production and pathogenicity but is not essential for immunogenicity and thus can be targeted to increase the safety of rabies vaccine vectors.\n          <\/jats:p>","DOI":"10.1128\/jvi.00889-08","type":"journal-article","created":{"date-parts":[[2008,7,31]],"date-time":"2008-07-31T00:55:28Z","timestamp":1217465728000},"page":"9730-9738","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":83,"title":["PPEY Motif within the Rabies Virus (RV) Matrix Protein Is Essential for Efficient Virion Release and RV Pathogenicity"],"prefix":"10.1128","volume":"82","author":[{"given":"Christoph","family":"Wirblich","sequence":"first","affiliation":[{"name":"Department of Microbiology and Immunology"},{"name":"Jefferson Vaccine Center, Thomas Jefferson University, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gene S.","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Papaneri","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology"},{"name":"Jefferson Vaccine Center, Thomas Jefferson University, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter J.","family":"Godlewski","sequence":"additional","affiliation":[{"name":"Department of Pathobiology, School of Veterinary Medicine, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan Marc","family":"Orenstein","sequence":"additional","affiliation":[{"name":"Department of Pathology, George Washington University, Washington, DC"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald N.","family":"Harty","sequence":"additional","affiliation":[{"name":"Department of Pathobiology, School of Veterinary Medicine, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias J.","family":"Schnell","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology"},{"name":"Jefferson Vaccine Center, Thomas Jefferson University, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.virol.2007.11.008"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1128\/jvi.67.1.407-414.1993"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.01743-06"},{"key":"e_1_3_2_5_2","first-page":"1","volume":"283","year":"2004","unstructured":"Conzelmann, K.
