rmcmv - The mouse macrophage cell line IC21 hex commander mod apk the mouse mammary epithelial tumor cell line C127I and the murine fibroblast cell line NIH 3T3 ATCC CRL1658 were obtained from the American Type Culture Collection Manassas VAC127I cells were maintained in DMEM supplemented with 10 FCS 10 Uml penicillin G 10 μgml streptomycin and 2 mM glutamine We have developed a murine cytomegalovirus MCMVvectored vaccine expressing the mouse zonapellucida3 gene rMCMVZP3 which successfully induces infertility in experimentally inoculated laboratory or wildderived mice However the future success of this vector as a fully disseminating vaccine Murine Cytomegalovirus Infection DownRegulates MHC Class II Expression Introduction Cytomegalovirus CMV is the leading viral cause of developmental brain disorders during the embryonic and perinatal periods in humans Microcephaly is the most prominent brainrelated manifestation of congenital CMV infection Even if there are no obvious symptoms at birth the infection occasionally persists and causes neurological disorders including sensorineural hearing Promoter control over foreign antigen expression in a murine Prolonged activation of cytomegalovirus early gene Immunization with Recombinant Murine Cytomegalovirus Expressing Murine Prolonged activation of cytomegalovirus early gene e1promoter We have developed a murine cytomegalovirus MCMVvectored vaccine expressing the mouse zonapellucida3 gene rMCMVZP3 which successfully induces infertility in experimentally inoculated laboratory or wildderived mice However the future success of this vector as a fully disseminating vaccine in freeliving mice may be compromised by preexisting immunity since there is a high prevalence Prior infection with murine cytomegalovirus MCMV limits the Promoter control over foreign antigen expression in a murine Immunization with recombinant murine cytomegalovirus expressing murine Introduction Effective immunocontraception requires the presentation of reproductive antigens in a target species to activate an kuis4d antigenspecific immune response that subsequently disrupts one or more essential steps in the reproductive process without other adverse health effects Virus constructs were produced by homologous recombination according to previously published methods 11 using the lacZ expressing RM427 as the parental virus The viruses and plasmids used to produce them are shown in Table 1All viruses were constructed by insertion of the antigen cassette into the ie2 region as shown in Fig 1 AVirus constructs were confirmed by RFLP Southern blot Zona pellucida ZP glycoproteins are promising candidate antigens for use in immunocontraceptive vaccines because of their crucial role in mammalian fertilization A single intraperitoneal immunization with recombinant murine cytomegalovirus engineered to express murine ZP3 rMCMVmZP3 induces per at Detection of EGFP MCMVE1 and MCMVM45 in rMCMV1373 or 448infected MEF and primary neuronal cultures Either rMCMV was allowed to infect both cell cultures at a MOI of 1 A potential use of MCMV as a vaccine vector may be as an immunocontraceptive vaccine to reduce mouse numbers in an attempt to limit the damage caused by periodic population eruptions in rural Australia 15We previously inserted the mouse zonapellucida3 mZP3 cDNA into the ie2 region of MCMV and showed that infection with this recombinant virus induces infertility in mice through a process Prior infection with murine cytomegalovirus MCMV limits the Prior infection with murine cytomegalovirus MCMV limits the Previous studies have reported on the development of a recombinant murine cytomegalovirus rMCMV containing the mouse zona pellucida 3 mZP3 gene for use as a virally vectored immunocontraceptive VVIC This study aimed to alter promoter control over foreign antigen makanan koki expression and cellular locali
