Peripheral blood mononuclear cells (PBMCs) from surviving ASFV-infected pigs responded to ASFV protein expression. The ELISPOT assay verified the ability of the 4 ASFV proteins and the inactivated ASFV to stimulate the production of IFN-γ on PBMCs of the surviving pigs (n = 20). A total of 0.5 μg/mL concanavalin A (Con A) was used as a positive stimulation. The data are shown as the mean ± SEM. p-values were determined by one-way ANOVA (ns, p > 0.05; * p < 0.05; *** p < 0.001; and **** p < 0.0001).
