Figure 2From: Memory T cell proliferative responses and IFN-γ productivity sustain long-lasting efficacy of a Cap-based PCV2 vaccine upon PCV2 natural infection and associated diseaseTotal resting PBMC and lymphoblasts upon in vitro stimulation after Cap protein PCV2 vaccination. Cell levels of resting and activated PBMC in PCV2-vaccinated (PCV2-vac) and control (C) pigs upon 48-h PCV2b (A, B) and PCV2b + PHA (C, D) in vitro stimulation during the post-vaccination (PV) period. Values are normalized to the corresponding medium (PCV2 stimulation) and PHA-alone (PCV2 + PHA stimulation) control samples, respectively. PCV2-vac pigs were vaccinated at 3 weeks of age using a PCV2a Cap protein-based subunit vaccine. (*): statistically significant difference between groups (p < 0.05).Back to article page
