3.6 Immunization with VLPs plus ISPA or CA increases IFN-γ secreted by bovine PBMCs
IFN-γ levels were measured in the supernatant of PBMC cultures from vaccinated bovines. At 45 dpv, the group immunized with VLPs-ISPA reached significantly higher levels of IFNγ than those inoculated with VLPs alone (p < 0.05) (Figure 6).
