FIG. 4.

Levels of IL-6, IL-8, and CCL2 in cultures of resting CD4⁺ T cells stimulated by EC. Resting CD4⁺ T cells were cultured alone, with MCF7, or with EC⁺/EC⁻ for 6 days, and the supernatants were collected and analyzed for 30 cytokines. (A) IL-6 levels in resting T cells cultured alone or stimulated by EC. EC cultured alone were included as well. (B) IL-8 levels in resting T cells cultured alone, with MCF7 or stimulated by EC. (C) CCL2 levels in resting CD4⁺ T cells cultured alone, with MCF7 or stimulated by EC. Samples were averaged from two different donors each in duplicates, and means ± standard errors are plotted.
