Figure 4From: Glimepiride reduces CD14 expression and cytokine secretion from macrophages Glimepiride reduces cytokine secretion from RAW 264 cells incubated with αSN. (A) The concentrations of TNF produced by RAW 264 cells incubated with αSN (●), βSN (■) or αSN and 1 μg/ml polymyxin B (□). Values are means ± SD from triplicate experiments performed 4 times, n = 12. (B) The concentrations of TNF produced by RAW 264 cells pre-treated with control medium (●), 5 μM glimepiride (○) or 5 μM glipizide (□) and incubated with αSN. Values are means ± SD from triplicate experiments performed 4 times, n = 12. (C) The concentrations of IL-1β produced by RAW 264 cells pre-treated with control medium (●) or 5 μM glimepiride (○) or 5 μM glipizide (□) and incubated with αSN. Values are means ± SD from triplicate experiments performed 4 times, n = 12. (D) The concentrations of IL-6 produced by RAW 264 cells pre-treated with control medium (●), 5 μM glimepiride (○) or 5 μM glipizide (□) and incubated with αSN. Values are means ± SD from triplicate experiments performed 4 times, n = 12.Back to article page
