Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
We identified DCIR2+DCs but not DEC205+DCs as able to induce peripheral T cell tolerance in pre-diabetic autoimmune NOD mice. To determine what distinct genetic programs are elicited in the auto-reactive CD4 T cells early after stimulation by these two DC subsets, we utilized adoptive transfer of BDC2.5 CD4 T cells into NOD mice, which were then given chimeric antibody to deliver the beta-cell specific antigen to either DCIR2+DCs or DEC205+DCs, leading to BDC2.5 CD4 T cell specific stimulation in vivo. The analysis shows that the negative transcriptional factor Zbtb32 (ROG) is up-regulated more in BDC2.5 CD4 T cells after stimulated with a antigen via DCIR2+DCs presentation, compared with DEC205+DCs, suggesting the involvement of Zbtb32 in DCIR2+DCs-mediated auto-reactive T cell tolerance in disease ongoing NOD mice.

Description
Malaria is a disease with diverse symptoms depending on host immune status and pathogenicity of Plasmodium parasites. The continuous parasite growth within a host suggests mechanisms of immune evasion and/or inhibition. To identify pathways commonly inhibited by malaria infection, we infected C67BL/6 mice with four Plasmodium yoelii strains causing different disease phenotypes and 24 progeny of a genetic cross. mRNAs from mouse spleens day 1 and/or day 4 post infection (p.i.) were hybridized to a mouse microarray to identify activated or inhibited pathways, upstream regulators, and linkages to parasite genetic loci. Strong interferon responses were observed after infection with N67 strain, whereas initial inhibition and later activation of hematopoiesis pathways were found after infection with 17XNL parasite. Inhibition of pathways such as Th1 activation, dendritic cell (DC) maturation, and NFAT immune regulation were observed in mice infected with all the parasite strains day 4 p.i., suggesting universally inhibited immune pathways. Treatment of infected mice with antibodies against T cell receptors OX40 or CD28 to activate malaria-inhibited pathways enhanced host survival. Controlled activation of these pathways may provide important strategies for better disease management and for developing an effective vaccine.

Description
An invading pathogen will trigger specific host responses, which can be explored to identify genes functioning in pathogen recognition and elimination. Here we performed trans-species expression quantitative trait locus (ts-eQTL) analysis using genotypes of the Plasmodium yoelii malaria parasite and phenotypes of mouse gene expression. We significantly (LOD score3.0) linked 1,054 host genes to many parasite genetic loci. Clustering genome-wide pattern of LOD scores (GPLSs), which produced results different from those of direct expression level clustering, grouped host genes functioning in related pathways together, allowing accurate functional prediction of unknown genes. As proof of principle, 14 of 15 randomly selected genes unknown, but predicted to function in type I interferon (IFN-I) responses, were experimentally verified using gene over expression, shRNA knockdown, viral infection, and/or infection of KO mice. This study demonstrates an effective strategy for studying gene function, establishes a functional gene database, and identifies regulators in IFN-I pathways.

Description
Mycobacterium tuberculosis infection (Mtb) is the leading cause of death due to a single infectious agent and among the top ten causes of all human death worldwide1. CD4 T cells are essential for resistance to Mtb infection, and for decades it has been thought that IFN production is the primary mechanism of CD4 T cell-mediated protection2,3. However, IFN responses do not correlate with host protection, and several reports have demonstrated that additional anti-tuberculous CD4 T cell effector functions remain unaccounted for4-8. Here we show that the TNF superfamily molecule CD153 (TNFSF8) is required for IFN-independent control of pulmonary Mtb infection by CD4 T cells. In Mtb infected mice, CD153 expression is highest on Ag-specific Th1 cells in the lung tissue parenchyma, but its induction does not require Th1 polarization. CD153 deficient mice develop high pulmonary but not splenic bacterial loads and succumb early to Mtb infection. Reconstitution of T cell-deficient hosts with either CD153-/- or IFN-/- CD4 T cells fails to rescue mice from early mortality, but reconstitution with a mixture of CD153-/- and IFN-/- CD4 T cells provides similar protection as WT T cells. In Mtb infected non-human primates, CD153 expression is much higher on Ag-specific CD4 T cells in the airways compared to the blood, and the frequency of Mtb-specific CD153-expressing CD4 T cells inversely correlates with bacterial loads in granulomas. In Mtb infected humans, CD153 defines a subset of highly polyfunctional Mtb-specific CD4 T cells that are much more abundant in individuals with controlled latent Mtb infection compared to those with active TB. In all three species, Mtb-specific CD8 T cells did not upregulate CD153 following peptide stimulation. Thus, we have identified expression of CD153 by CD4 T cells as a major immune mechanism of host protection against pulmonary Mtb infection.
