Frequency of cytokine-producing cells in the macrophage gate, R3. (A) Percentage of CD14⁺ TNF-α-producing monocytes in the whole gated population; (B) percentage of CD14⁺ IL-12-producing monocytes in the whole gated population; and (C) percentage of IL-10-producing monocytes. The means were compared using the statistical program JMP and Student's t test; comparison of all pairs was made with a P value of <0.05. In all cases, there were no significant differences using the 95% confidence interval.
