Figure 1. EGCG inhibits IL-1β-induced cytokine release in HCEpiC. Cells were cultured in complete (HCGS-containing) medium, followed by glucocorticoid-free medium for 18 h. Cells were then treated with 1 ng/ml IL-1β in the presence of EGCG for 18 h. G-CSF (A), GM-CSF (B), IL-6 (C), IL-8 (D), and MCP-1 (E) levels in the media were analyzed by Luminex. White bar represents control; black bar represents IL-1β; gray bar represents EGCG alone, black circles + line represent EGCG. Lines are the linear interpolation between data points. Data are presented as mean±SEM, n=3. *versus IL-1β; p<0.05.
