We have developed a reverse genetics system to produce live recombinant PICV (strain P18) with a trisegmented RNA genome (rP18tri), which encodes all four PICV gene products and as many as two foreign genes. We have engineered the vector to express the green fluorescent protein (GFP) reporter gene (abbreviated as G in virus designations) and either the hemagglutination (HA [H]) or the nucleoprotein (NP [P]) gene of the influenza A\/PR8 virus. The trisegmented viruses rP18tri-G\/H and rP18tri-G\/P showed slightly reduced growth\n            <jats:italic>in vitro<\/jats:italic>\n            and expressed HA and NP, respectively. Mice immunized with rP18tri-G\/H were completely protected against lethal influenza virus challenge even 120 days after immunization. These rP18tri-based vectors could efficiently induce both neutralizing antibodies and antigen-specific T cell responses via different immunization routes. Interestingly, the immune responses were significantly increased upon a booster dose and remained at high levels even after three booster doses. In summary, we have developed a novel PICV-based live vaccine vector that can express foreign antigens to induce strong humoral and cell-mediated immunity and is ideal for a prime-and-boost vaccination strategy.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>IMPORTANCE<\/jats:bold>\n            We have developed a novel Pichinde virus (PICV)-based live viral vector, rP18tri, that packages three RNA segments and encodes as many as two foreign genes. Using the influenza virus HA and NP genes as model antigens, we show that this rP18tri vector can induce strong humoral and cellular immunity via different immunization routes and can lead to protection in mice. Interestingly, a booster dose further enhances the immune responses, a feature that distinguishes this from other known live viral vectors. In summary, our study demonstrates a unique feature of this live rP18tri vector to be used as a novel vaccine platform for a prime-and-boost vaccination strategy.\n          <\/jats:p>","DOI":"10.1128\/jvi.02705-15","type":"journal-article","created":{"date-parts":[[2015,12,17]],"date-time":"2015-12-17T03:58:16Z","timestamp":1450324696000},"page":"2551-2560","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":35,"title":["A Novel Live Pichinde Virus-Based Vaccine Vector Induces Enhanced Humoral and Cellular Immunity after a Booster Dose"],"prefix":"10.1128","volume":"90","author":[{"given":"Rekha","family":"Dhanwani","sequence":"first","affiliation":[{"name":"Department of Veterinary and Biomedical Sciences, College of Veterinary Medicine, University of Minnesota, Twin Cities, Minnesota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanqin","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Veterinary and Biomedical Sciences, College of Veterinary Medicine, University of Minnesota, Twin Cities, Minnesota, USA"},{"name":"College of Veterinary Medicine, Huazhong Agricultural University, Wuhan, Hubei, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qinfeng","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Veterinary and Biomedical Sciences, College of Veterinary Medicine, University of Minnesota, Twin Cities, Minnesota, USA"},{"name":"Department of Swine Infectious Diseases, Shanghai Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vikram","family":"Verma","sequence":"additional","affiliation":[{"name":"Department of Veterinary and Biomedical Sciences, College of Veterinary Medicine, University of Minnesota, Twin Cities, Minnesota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mythili","family":"Dileepan","sequence":"additional","affiliation":[{"name":"Department of Veterinary and Biomedical Sciences, College of Veterinary Medicine, University of Minnesota, Twin Cities, Minnesota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hinh","family":"Ly","sequence":"additional","affiliation":[{"name":"Department of Veterinary and Biomedical Sciences, College of Veterinary Medicine, University of Minnesota, Twin Cities, Minnesota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuying","family":"Liang","sequence":"additional","affiliation":[{"name":"Department of Veterinary and Biomedical Sciences, College of Veterinary Medicine, University of Minnesota, Twin Cities, Minnesota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","first-page":"1791","volume-title":"Fields virology","author":"Buchmeier MJ","year":"2007","unstructured":"Buchmeier MJ, De La Torre JC, Peters CJ. 2007.
