From: Bovine lactoferrin free of lipopolysaccharide can induce a proinflammatory response of macrophages
Expression of mRNA for IL8 (a and b) and TNFα (c and d) by HEK cell line expressing no TLR (a and c) or the same cell line expressing TLR4a-MD2-CD14 (b and d) after stimulation with two concentrations of lactoferrin (LF) or 1 μg/ml of lipopolysaccharide (LPS). Data are shown as mean ± SD of 5 repetitions. Different letters show statistical significance when compared with control (p < 0.05)
