Selected candidate lipids were tested for their inhibitory activity on R837-induced (5 μg/ml; 18 h) cytokine secretion in BMDCs. Concentrations of indicated lipids: PECPC (10 μM), PEIPC (10 μM), OxPAPC (40 μg/ml), DPPC (40 μg/ml), POVPC (40 μM), PGPC (40 μM), and KOdiAPC (40 μM). Representative data (mean ± SD of triplicate determinations) from one of three independent experiments are shown. ****P < 0.0001; ns, not significant; as determined by one-way ANOVA adjusted by Sidak's multiple comparisons test.
