Macrophages play major roles in the onset of immune responses and inflammation by inducing a variety of cytokines such as TNF and IFN-beta. The pathogen-associated molecular pattern, polyinosinic-polycytidylic acid [poly(I:C)], and LPS were used to study type-I IFN and TNF responses in human macrophages. Additionally, activation of the key signaling(More)
Listeria monocytogenes is a prototypic bacterium for studying innate and adaptive cellular immunity as well as host defense. Using human monocyte-derived macrophages, we report that an infection with a wild-type strain, but not a listeriolysin O-deficient strain, of the Gram-positive bacterium L. monocytogenes induces expression of IFN-beta and a bioactive(More)
Induction of interferon-beta (IFN-beta) gene expression is a tightly regulated process, and a plethora of studies identified the signal transduction pathway TANK-binding kinase-1 (TBK-1)/IFN regulatory factor-3 (IRF-3) as essential to the induction of IFN-beta gene expression. Data regarding the role of p38 and JNK are rare, however. We investigated the(More)
