Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
We describe a novel subset of CD8+ DCs in lymphoid organs of nave mice characterized by expression of the CX3CR1 chemokine receptor. CX3CR1+CD8+ DCs lack hallmarks of classical CD8+ DCs, including IL12 secretion, the capacity to cross-present antigen and their developmental independence of the transcriptional factor BatF3. Gene expression profiling showed that CX3CR1+CD8+ DCs resemble CD8- cDCs. The microarray analysis further revealed a unique plasmacytoid DC (PDC) gene signature of CX3CR1+ CD8+ DCs. A PDC relationship of the cells is further supported by the fact that they harbor characteristic D-J immunoglobulin gene rearrangements and that development of CX3CR1+CD8+ DCs requires E2-2, the critical transcriptional regulator of PDCs. Thus, CX3CR1+ CD8+ DCs represent a unique DC subset, related to but distinct from PDCs.

Description
The cytokines GM-CSF and IL-5 are thought to possess largely divergent functions despite a shared dependence on the common beta (βC) chain to initiate signaling. Although IL-5 is part of the core type 2 cytokine signature and is required for protection against some helminths, it is dispensable for immunity to others, such as Heligmosomoides polygyrus bakeri (H. polygyrus). Whether this is due to compensatory mechanisms is unclear. The transcription factor Bhlhe40 has been shown to control GM-CSF production and is proposed to be a novel regulator of T helper type 2 cells.

Description
Interleukin 2 (IL-2) promotes proliferation and differentiation of CD8+ T cells in vitro and in vivo. To define gene expression regulated by IL-2, we purified naive CD8+ T cells, activated them for 2 days followed by treatment with recombinant IL-2 or with neutralizing antibody against IL-2 and compared gene expression between the two treatments.

Description
Retention of lymphocytes in the intestinal mucosa requires specialized chemokine receptors and adhesion molecules. Here we find that both CD4+CD8+ and CD4+T cells in the intestinal epithelium, as well as CD8+T cells in the intestinal mucosa and mesenteric lymph nodes, express the cell adhesion molecule Crtam upon activation, whereas the ligand of Crtam, Cadm1, is expressed on gut CD103+DCs. Lack of Crtam-Cadm1 interactions in Crtam-/- and Cadm1-/- mice results in loss of CD4+CD8+T cells, which arise from mucosal CD4+T cells that acquire a CD8 lineage expression profile. Following acute oral infection with T. gondii, both WT and Crtam-/- mice mounted a robust TH1 response, but markedly fewer TH17 cells were present in the intestinal mucosa of Crtam-/- mice. The almost exclusive TH1 response in Crtam-/- mice resulted in more efficient control of intestinal T. gondii infection.

Description
Immune-Responsive Gene 1 (Irg1) is a mitochondrial enzyme that produces itaconate under inflammatory conditions principally in cells of myeloid lineage. Cell culture studies suggest that itaconate regulates inflammation through inhibitory effects on cytokine and reactive oxygen species production. To evaluate the functions of Irg1 in vivo, we challenged wild-type (WT) and Irg1 KO mice with Mycobacterium tuberculosis (Mtb) and monitored disease progression. Irg1 KO but not WT mice succumbed rapidly to Mtb, and mortality was associated with increased infection, inflammation, and pathology. Infection of LysM-Cre Irg1 flox, MPR8-Cre Irg1 flox, and CD11c-Cre Irg1 flox conditional knockout mice along with neutrophil depletion experiments revealed a role for Irg1 in alveolar macrophages and LysM+ myeloid cells in preventing neutrophil-mediated immunopathology and disease. RNA-seq analyses suggest that Irg1 and its production of itaconate temper Mtb-induced inflammatory responses in myeloid cells at the transcriptional level. Thus, Irg1 modulates inflammation to curtail Mtb-induced lung disease. Overall design: Neutrophils were purified from bone marrow of naïve mice by negative selection using magnetic-activated cell sorting beads (Miltenyi). Neutrophil purity (>95%) was assessed by flow cytometry as the percentage of Ly6G+ CD11b+ cells. Neutrophils were cultured in RPMI-1640 supplemented with 1% non-essential amino acids at 37°C, 5% CO2. GFP-Mtb was grown to mid-log phase, washed with PBS, sonicated to disperse clumps, and resuspended in neutrophil culture media. GFP-Mtb then was opsonized prior to infection by mixing with an equal volume of normal mouse sera (Sigma) and incubation at room temperature for 30 min. Neutrophils were mock-infected or infected with opsonized GFP-Mtb at MOI 1 and incubated at 37°C, 5% CO2.
