Figure 4. Release of cytokines and chemokines from monocytes by SP.
SP was incubated for 0, 30, 60, 120, 180, and 240 minutes at 37° C with 2 × 106/ml monocytes. Cytokines [GM-CSF (A), IFN-γ (B), TNF- α (C)] and chemokines[MIP-1α (D), MIP-1β (E), RANTES (F)] are from monocytes as indicated. The data shown are presented as the mean ± SEM of triplicate and are representative of three experiments.
