FIG. 2.

Inhibition of production of IL-1β, TNF-α, IL-6, and IFN-γ (A) and of MCP-1, MIP-1α, and MIP-1β (B) by PBMC stimulated with either SEB (150 ng/ml), TSST-1 (150 ng/ml), or LPS (100 ng/ml) in the presence of 0.2 mM D609. Values represent means ± standard errors of the means for PBMC cultures from 12 blood donors for experiments with SEB and TSST, and a subset of 3 donors for LPS. Results are statistically significant (P < 0.02) between SE and SE-plus-D609 samples and between LPS and LPS-plus-D609 samples. N/A, not applicable.
