FIG. 5.

Incubation of PMN in environments enriched for saturated fatty acids (FA), MUFA, and PUFA. Isolated PMN were incubated for 5 h at 37°C in a 1:1 molar ratio of individual fatty acids complexed with BSA. The final concentrations of fatty acids was 33 μM, and control samples were incubated in BSA alone. Cellular fatty acid profiles and chemiluminescence responses to fMLP were recorded for the washed cells. The data are expressed as mean ± SEM for six different PMN donors. The results were significantly different (P values) at the following levels: ∗, <0.05; ∗∗, <0.01. Significance was determined with the Wilcoxon rank sum test.
