Molecular adjuvants were used to augment the amplitude of the immune response in many studies recently. Ubiquitin (ub), the peptide binding truncated C-terminal portion of heat shock protein 70 (hsp70c) and interleukin-2 (IL-2) are widely investigated adjuvants which have been proved to be efficient. In our study, we compared the enhancing ability of these three adjuvants based on DNA vaccination using the porcine circovirus type 2 ORF2 (capsid) gene in mice. The results of lymphocyte proliferation assay, flow cytometric analysis (FCM), antibody titer and cytokine production showed that ub conjugated plasmid induced a stronger Th1 type cellular immune response and an observably higher level of Cap-specific serum immunoglobulin G antibody compared with hsp70c or IL-2 conjugated plasmids during the period of post-immunization. Meanwhile, the ub conjugation vaccinated group elicited stronger specific immunity against PCV2 challenge than the others during most of the time of post-challenge. Thus, these data indicate that ub is a superior adjuvant for a PCV2 DNA vaccination than the hsp70c and IL-2 molecules.
