Figure 4. 17 (R)-RvD1 attenuate IFN-γ and LPS induced TNF induction in rat primary astrocytes.

Figure 4

Bar graphs showing levels of TNF in media from primary rat astrocyte cultures (A) following stimulation with IFN-γ (1000 U/ml, 24 h), LPS (2 µg/ml, 24 h) or the combined effect of IFN-γ (1000 U/ml, 4 h) followed by LPS (2 µg/ml, 20 h). Pretreatment with 17(R)-RvD1 (500 nM, 30 min) significantly reduced IFN-γ (B) and LPS-induced (C)-TNF release. No significant effect was seen after pretreatment with LXA4 (500 nM, 30 min). Each bar represents mean ± S.E.M, * represents a significant difference at p<0.05 as compared to PBS (A) or indicated in the figure (B-D).
