Abstract:
To develop a safe and effective new generation vaccine for IRKV-THChina12 prevention, we constructed a non-replicative recombinant human adenovirus carrying the IRKV-THChina12 G gene, named as rAd5-IRKV-G. The IRKV-THChina12 G protein expressed by the recombinant human adenovirus in 293AD cells was detected by western blot and indirect immunofluorescence test. To evaluate the immunogenicity of the recombinant, mice were immunized with rAd5-IRKV-G by intramuscular (i. m.) or intraperitoneal (i. p.) route and with non-exogenous gene expressing wild type adenovirus wt-rAd5 as a control. Results showed that the rAd5-IRKV-G could induce continuous and statistically significant (P ≤ 0.05) anti-IRKV neutralizing antibody (NA) production in immunized mice by i. m. or i. p. route. In particular, no significant difference (P > 0.05) of the NA titers between the two administration routes were observed, that provides an alternative choice for animal immunization method in the future application.
