FIG. 6.

Myristic, pentadecanoic, palmitic, and palmitoleic acids inhibit GPI-induced TNF-α production. Macrophages were incubated for 24 h with medium alone (open bars), with Pfα alone (black bars), or with myristic acid (A), pentadecanoic acid (B), palmitic acid (C), palmitoleic acid (D), stearic acid (E), or oleic acid (F) at a concentration of 1 μM (light gray bars) or 10 μM (dark gray bars) or the six fatty acids together (G) added 30 min before Pfα was added. The values are means ± standard deviations of triplicate samples in a representative experiment.
