Fig. 1. EPA prevents LPS-induced production of TNF-. THP-1 cells were stimulated with graded concentrations of LPS for 6 hours after pre-incubation with or without 60 µM of EPA for 24 hours. Cells were collected and TNF- levels were determined in cell culture supernatant by ELISA. Mean ± S.E., n = 3. *Significantly different from LPS group (p < 0.05). Data are representative of three experiments.
