Reduced IL-2 detection in the presence of PBMC, TT, and LTA purified from S. aureus, S. faecalis, S. pyogenes, and S. mutans. PBMC and TT were incubated in AIM V for 3 days at 37°C with purified LTA from four different strains of gram-positive bacteria as described in Materials and Methods. IL-2 levels were then measured using ELISA. Data points shown represent the means of triplicate samples ± standard deviations.
