ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the immune potency of recombinant adenovirus combined with rAAV1 vector expressing HPV16L1 protein in mice.</p><p><b>METHODS</b>The rAdV and rAAV1 vector containing codon-modified HPV16L1 gene was constructed using Admax and AAVmax packaging system respectively. C57 BL/6 mice were immunized with purified rAdV and rAAV1 vector through intramuscular and intranasal inoculation routes, and the titer of neutralizing antibody was determined by neutralization assay based HPV16 pseudovirus.</p><p><b>RESULTS</b>Intramuscular immunization by rAAV1-mod. HPV16L1 or combined with rAd-mod. HPV16L1 can induce higher titer of neutralizing antibody in serum than that of other groups. The titer of neutralizing antibody of intranasal groups is significantly lower than that of intramuscular group, although the prime-boost strategy using in intranasal group was effective to enhance the specific humoral immunity.</p><p><b>CONCLUSION</b>The rAAV1-mod. HPV16L1 combined with rAd-mod. HPV16L1 can induce higher titer of neutralizing antibody in serum through intramuscular route than that of other groups at the 16th week after the first immunization.</p>
