- Results from IL-10, IL-8, IFN-α and TNF-α ELISA tests are expressed as pg/mL of serum. Results from IFN-γ ELISPOT are expressed as number of IFN-γ- secreting cells /5 × 105 PBMC. In brackets, the number of positive animals per treatment and time point. DC day of challenge, ND non-detectable (below limit of detection of the technique), NS non-significant; blank cell indicates not measured
