Protection against a primary PC challenge in CD4-depleted mice after DNA immunization. CD4-depleted mice were vaccinated with 3 rounds of control (pCD40L), pKexin, or pKexin/CD40L followed by challenge with PC. PC was quantified by quantitative real-time PCR (A) or by histology (B). n = 4–6. All data are mean values ± SEM. *P < 0.05, **P < 0.01 compared with control.
