ABSTRACT
<p><b>OBJECTIVE</b>To construct and characterize recombinant adenoviruses containing glycoprotein (GP) gene from rabies virus CVS-N2C strain.</p><p><b>METHODS</b>To obtain the recombinant adenovirus by pAdEasy system, identify recombinant virus with cDNA sequencing, Northern blot, Dot blot, Western blot and challenge-protection experiment of mice.</p><p><b>RESULTS</b>Recombinant adenovirus showed typical adenovirus morphological characteristics; the viral genome was stable; GP specific mRNA and presence of glycoprotein were determined in rAdGPcvs and rAdGPcvs' infected cells. The glycoprotein produced by recombinant adenovirus had a molecular mass of 66,000, which was similar to that of natural glycoprotein. In the group of rAdGPcvs immunized mice, 87.5%-100% of mice survived from a 35.8LD50/38.0LD50 lethal rabies intracerebral challenge. Finally 73.3%-83.3% of the mice that had received eAdGPcvs survived, and all the Ad5 immunized mice succumbed to rabies.</p><p><b>CONCLUSION</b>Recombinant adenovirus rAdGPcvs and rAdGPcvs' hold great potential to be developed as recombinant rabies vaccines, and at the same time, it is actually the first study that on high neuropathogenicity rabies CVS-N2C glycoprotein based adenoviral recombinants.</p>
