Proliferative response against peptides (20 μg/ml per well) and virus (5·105 pfu/ml) of PBMCs obtained at day 39 from peptide-immunized pigs (group 1 and 2). Results are expressed as SI and each bar represents the mean of triplicate cultures. The background cpm values (obtained with lymphocytes incubated with medium alone or mock-infected cells) were always ≤ 2300 cpm.
