Description
Type I Interferons encompasses a large family of closely related cytokines comprising of at least 13 IFN- isotypes and single IFN-. Both IFN- and IFN- exert their activity through a common receptor IFNAR. Type I Interferons have broad regulatory effects and various subtypes of dendritic cells are influenced by this cytokines. In our study we asked question whether the low, constitutive levels of type I Interferons produced under steady state conditions are important for proper function of splenic conventional dendritic cells.

Description
The goal of this project was to characterize DCs from lymphopenic mice, like RAG (recombination activated gene) deficient mice and to examine the influence of mature B and T cells on the antigen presenting ability of splenic cDCs. We demonstrate how cellular cross-talk can shape the character and function of cDCs. Lymphopenic conditions, where splenic cDCs have to develop and differentiate, drastically change their character and their ability to cross-present soluble antigen.

Description
To acquire more information regarding the local immune events during the different phases of S. aureus infection, gene profiling using microarray technology was used to identify host genes whose expression is substantively altered in the kidneys during the acute (T2) and persistent phase of infection (T28). Genes associated with the distinct transcript profiles were identified by comparing the relative abundance of transcripts at 2 days (acute) and 28 days (persistent) of infection to their abundance in the kidneys of uninfected control animals (CTL).

Description
The gene expression profile of peripheral Foxp3+ natural regulatory T cells isolated from Foxp3/EGFP bicistronic mice was compared to that of in vitro-induced regulatory T cells and to CD4+ conventional (Foxp3-) T cells. The role of the regulatory T cell transcription factor Foxp3 in shaping the transcriptosomes of natural and induced regulatory T cells was analyzed using mice expressing a mutant FOXP3-EGFP fusion protein (Foxp3deltaEGFP).

Description
Human and mouse blood each contain two monocyte subsets. Here, we investigated the extent of their similarity using a microarray approach. Approximately 300 genes in human and 550 genes in mouse were differentially expressed between subsets. More than 130 of these gene expression differences were conserved between mouse and human monocyte subsets. We confirmed numerous differences at the cell surface protein level. Despite overall conservation, some molecules were conversely expressed between the two species subsets, including CD36, CD9, and TREM-1. Furthermore, other differences existed, including a prominent PPAR signature in mouse monocytes absent in human. Overall, human and mouse monocyte subsets are far more broadly conserved than currently recognized. Thus, studies in mice may indeed yield relevant information regarding the biology of human monocyte subsets. However, differences between the species deserve consideration in models of human disease studied in the mouse.

Description
The relative contribution of induced and natural Foxp3+ regulatory T cells (iTreg and nTreg cells, respectively) to the maintenance of tolerance is unknown. We examined their respective roles by in vivo adoptive transfer immunotherapy of newborn Foxp3-deficient BALB/c mice. Survival, weight gain, tissue infiltration, T cell activation, and the concentration of proinflammatory cytokines were used as outcome measurements. Treatment with iTreg cells alone was not successful. While effective in preventing death, treatment with nTreg cells alone was associated with chronic inflammation and autoimmunity. Outcomes markedly improved when conventional T (Tconv) cells were transferred together with the nTreg cells, where 10% of the peripheral Treg cell pool was derived by in-situ conversion. This enhancement depended upon the capacity of Tconv cells to express Foxp3.
