Effects of pretreatment of neutrophils with docosahexaenoic acid (5 and 10 µg/ml) on pneumolysin (Ply, 8·37 and 41·75 ng/ml)-mediated nuclear translocation of NFκB following 30 min exposure to the toxin. The results are presented as the mean percentages ± s.e.m. of the pneumolysin-free control system (data from 6 experiments). *P < 0·05 for comparison with the pneumolysin-free control system. ΔP < 0·05 for comparison with the corresponding pneumolysin-treated, DHA-free system.
