FIG. 6.
Induction of IL-8 release by p-TUA in THP-1 cells in culture. The OCT-differentiated THP-1 cells were stimulated by p-TUA and reference Salmonella serovar Abortus-equi LPS at the indicated concentrations for 24 h in triplicate. The IL-8 levels in THP-1 cell culture supernatants were determined by ELISA and are expressed as means ± standard deviations. ∗∗, P < 0.01 versus medium alone. The results are representative of those from three different experiments.
