Fig. 4: Relative expression of the selected genes (X-axis) in the PBMCs treated with PNAG or SpA expressed as 2-ΔΔCt normalized to the reference gene (18S rRNA).

The values are presented as the means and standard errors (SE) of 6 independent experiments. Significance is indicated as follows: * p < 0.05, ** p ≤ 0.01, **** p ≤ 0.01. Abbreviations: PNAG: poly N-acetylglucosamine, SpA: S. aureus virulence protein A.
