LPS triggers LTB4 production and γδ T lymphocyte accumulation. (A) LTB4 levels were determined by EIA in C57BL/6 mouse pleural fluid obtained at indicated time-points after i.pl. injection of saline or LPS (250 ng/cavity). Results are expressed as the mean ± sem from triplicate wells of one out of three separate experiments. (B) γδ T lymphocyte accumulation in the pleural cavity of C57BL/6 mice 6, 12, and 24 h after LPS i.pl. injection (250 ng/cavity). Results are expressed as the mean ± sem from at least six animals/group in three different experiments. *, Statistically significant differences (P≤0.05) compared with control group.
