TLR4-dependent ferroportin suppression by neutrophils and macrophages exposed to bacterial pathogens. (A) Western blot of ferroportin production in murine bone marrow derived macrophages stimulated with PA. (B) Real-time PCR for ferroportin mRNA using WT and Tlr4^Lps-d bone marrow derived macrophages infected with PA. Quantitative assays performed in triplicate and representative of 3 repeated experiments. Data are shown as mean of values ± SD.
