Analysis of BMDMs primed with IFNγ and subsequently activated with LPS. Pro-inflammatory macrophages are induced by the Th1 cytokine IFNγ and/or the toll-like receptor ligand LPS. Results provide insight into the molecular effects of IFNγ priming on LPS-induced inflammation in macrophages.

(Submitter supplied) Macrophages are a heterogeneous population of immune cells, which are critical for both the initiation and resolution of inflammation. Pro-inflammatory macrophages can be induced by the Th1 cytokine IFNγ and/or TLR triggers, like LPS. Here, we investigated the effects of IFNγ priming on LPS-induced gene expression in primary mouse macrophages.

(Submitter supplied) Atherosclerosis is a disease of large and medium-sized muscular arteries and is characterized by vascular inflammation and lipid-laden plaque formation within the intima of the vessel wall. Atherosclerosis is initiated by recruitment of blood leukocytes to the injured vascular endothelium and leads to altered contractility of Vascular Smooth Muscle Cells (VSMCs), acute and chronic luminal obstruction, abnormalities of blood flow and diminished oxygen supply to target organs. more...

(Submitter supplied) Complete activation of macrophage proinflammatory and antimicrobial phenotype is promoted by combined action of IFN-g and LPS. Synergistic activation of canonical inflammatory NF-kB target genes by IFN-g and LPS is well appreciated, but less is known about whether IFN-g negatively regulates components of the LPS response, and how this affects polarization. A combined transcriptomic and epigenomic approach revealed that IFN-g selectively abrogates LPS-induced feedback and select metabolic pathways by suppressing TLR4-mediated activation of gene enhancers. more...

(Submitter supplied) Synergistic activation of inflammatory cytokine genes by IFN-gamma and TLR signaling is important for innate immunity and inflammatory disease pathogenesis, but underlying mechanisms are not known. By obtaining over three billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of human primary monocytes under IFN-gamma-priming and TLR stimulation. more...

(Submitter supplied) Immunological memory is generally thought to be mediated exclusively by lymphocytes such as memory T and B cells. However, enhanced innate immune responses caused by a previous infection increase protection against reinfection suggesting the presence of innate immunological memory. Here, we describe 3,811 ATF7 binding sites in mouse peritoneal macrophages, and 95% of the ATF7 signals in wild-type macrophages are lost in ATF7 knockout macrophages. more...
