Analysis of B lymphocyte-induced maturation protein 1 (BLIMP1) conditional knockout macrophages infected with Listeria monocytogenes for 2 hr. Results provide insight into BLIMP1-mediated regulatory mechanisms in macrophages in early host defense against intracellular bacteria.

(Submitter supplied) The transcriptional repressor BLIMP1 is a master regulator of B and T cell differentiation. To examine the role of BLIMP1 in innate immunity we used a conditional knockout (CKO) of Blimp1 in myeloid cells and found that Blimp1 CKO mice were protected from lethal infection induced by Listeria monocytogenes. Transcriptome analysis of Blimp1 CKO macrophages identified the murine chemokine (C-C motif) ligand 8, CCL8 as a direct target of Blimp1-mediated transcriptional repression in these cells. more...

(Submitter supplied) We observed that mice with the Treg-specific deletion of Blimp1 had delayed and smaller tumor growth associated with the activation of tumor-infiltrating immune effector cells. To determine what extent disruptions of Treg suppressive activity by a specific deletion of Blimp1 could impact on the tumor, we assessed the gene expression of sorted tumor cells by NanoString analysis.

(Submitter supplied) A majority of effector Treg cells (eTregs) that are abundant in many types of tumors are marked by the expression of Blimp1. However, the specific impact of Blimp1+ eTregs on, and mechanisms of action within, tumors remain unknown. To better understand the role of Blimp1 in the regulation of eTreg function in the tumor immunity, we profiled the differential gene expression in Blimp1-deficient eTregs compared to WT control eTregs from tumor-bearing mice.

(Submitter supplied) Listeriosis is an infectious disease caused by the intracellular bacterium Listeria monocytogenes. To control the infection effectively, the host immune response is directed by intercellular signalling molecules called cytokines that are produced by immune cells following sensing of the bacteria. In this study we used gene expression analysis to examine complex immune signalling networks in the blood and tissues of mice infected with L. more...

(Submitter supplied) Osteoclastogenesis is induced by the stimulation of RANKL. In the early stage of osteoclast differentiation, the osteoclast progenitor cells are primed by M-CSF, following a tightly controlled genetic program where specific sets of genes are up-regulated by RANKL. Some of them, for instance, control differentiation, cell-cell fusion and bone resorption. We used microarrays to detail the global program of gene expression underlying osteoclastogenesis and identified various up-regulated genes during this process.

(Submitter supplied) Listeria monocytogenes (LM) is a Gram-positive, facultative intracellular bacterium responsible for disseminated infections in immunocompromised individuals which can result in septicaemia and meningitis (1). Effective control of listeriosis requires both innate and adaptive immune responses with the principal mediators of bacterial killing being neutrophils and macrophages (2). Key cytokines driving the innate immune response are IFN-γ (3) and TNF (4), which promote macrophage activation and drive the production of anti-microbial mediators such as reactive oxygen intermediates (ROI) and reactive nitrogen intermediates (RNI). more...

(Submitter supplied) Expression of Blimp-1 was specifically deleted in dendritic cells (DCs) by breeding Blimp-1 flox and CD11c-CRE mice. MiRNA expression was evaluated and compared from DCs, CD4+ T cells and total B cells from spleens of control and Blimp-1 KO mice.

(Submitter supplied) Gene-expression microarray datasets generated as part of the Immunological Genome Project (ImmGen). Primary cells from multiple immune lineages are isolated ex-vivo, primarily from young adult B6 male mice, and double-sorted to >99% purity. RNA is extracted from cells in a centralized manner, amplified and hybridized to Affymetrix 1.0 ST MuGene arrays. Protocols are rigorously standardized for all sorting and RNA preparation. more...
