Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Cebpa is a gene known for its role in hematopoetic development. Though it is proven to be indispensible in myelopoesis, the details of the role played by Cebpa in dendritic cell development is fairly unknown. Steady state DC development can be modelled in vitro by treating Lin- HSPC with FLT3L.

Description
Preparation of exosomes isolated from semen contain a substantial amount of RNA, mostly from 20 to 100 nucleotides in length. We sequenced separately 20-40 and 40-100 nucleotide fractions of RNA from exosomes isolated from semenal fluid from six healthy donors. We found various classes of small non-coding RNA, including mature microRNA and piwi-RNA, as well as abundant Y RNAs and tRNAs present in both full length and fragmented forms. Specific RNAs were consistently present in all donors. For example, fifteen (of ~2,600 known) microRNAs constituted over 80% of mature microRNA in SE. Additionally, tRNA fragments were strongly enriched for 5’-ends of 18-19 or 30-34 nucleotides in length. Overall design: Size-fractionated small RNA profiles from exosomes isolated from the seminal fluid of six healthy donors
Publication Title
Exosomes in human semen carry a distinctive repertoire of small non-coding RNAs with potential regulatory functions.

Description
Langerhans dendritic cells represent abundantly occuring and evolutionary highly conserved DCs specifically located in the stratified epithelial tissues. LCs are unique among DC family members in that they express epithelial-type adhesion molecules, allowing them to form a tight three-dimensional network in basal and suprabasal epidermal keratinocyte layers and developmentally dependent on the cytokine TGF-1. In the present study, we identified BMP-7 as another key factor inducing LC differnetiation. Here we have performed comparative analysis of highly purified CD207+/CD1a+ in vitro generated Langerhans cells in the presence of BMP-7 and TGF-1. We have identified that both BMP-7-LCs and TGF-1-LCs are closely related to each other.

Description
Complex regulatory mechanisms control continuous maintenance of myeloid progenitors and renewal of differentiated cells. Transcription factors play a important role in these processes. Here we report that the activation the calcineurin-NFAT signaling pathway inhibit the proliferation of myeloid granulocyte-monocyte progenitor (GMP). Myeloid progenitor subtypes possessed different susceptibilities to Ca2+ flux induction and consequently differential engagement of the calcineurin-NFAT pathway. This study show that inhibition of the calcineurin-NFAT pathway enhanced proliferation of GMPs both in vivo and in vitro. The calcineurin-NFAT signaling in GMPs is initiated through Flt3-L. The inhibition of the calcineurin-NFAT pathway altered the expression of the cell cycle regulation genes CDK4, CDK6, and CDKN1A, thus enabling faster cell cycle progression. The extensive use of NFAT inhibitors in the clinic should take into account that, in addition to the immunosuppression role in lymphoid cells, these NFAT inhibitors also affect the maintenance of the myeloid compartment.

Description
The transcription factor STAT1 is essential for interferon- (IFN) mediated protective immunity in humans and mice. Two splice isoforms of STAT1, STAT1 and STAT1, differ with regard to a C-terminal transactivation domain, which is absent in STAT1. Dimers of STAT1 are therefore considered transcriptionally inactive and potential competitive inhibitors of STAT1. Contrasting this view, generation and analysis of mice deficient for either STAT1 or STAT1 demonstrated transcriptional activity of the STAT1 isoform and its enhancement of innate immunity. Gene expression profiling in primary cells revealed overlapping, but also non-redundant and gene-specific activities of STAT1 and STAT1 in response to IFN. Consistently, both isoforms mediated protective, IFN-dependent immunity against the bacterium Listeria monocytogenes, although with remarkably different efficiency. In contrast, STAT1 and STAT1 were largely redundant for transcriptional responses to IFN/ and for IFN/-dependent antiviral activity. Collectively, our data shed new light on how STAT1 isoforms contribute to antimicrobial immunity.

STAT1β is not dominant negative and is capable of contributing to gamma interferon-dependent innate immunity.

Description
Peptide immunotherapy aims to specifically restore tolerance to the administered self-antigen and prevent autoimmunity without the perturbation of normal immune function. We have developed a dose escalation protocol for subcutaneous delivery of the MHC II-restricted myelin basic protein peptide analogue Ac1-9[4Y] to T cell receptor transgenic (Tg4) mice. Dose escalation allows safe administration of high doses of peptide, which effectively induces antigen-specific tolerance and suppresses the development of experimental autoimmune encephalomyelitis, a model for the human condition multiple sclerosis. CD4+ T cells isolated from treated mice are anergic and suppressive in vitro and respond to stimulation by secretion of the immunoregulatory cytokine IL-10. To understand the molecular changes occurring throughout the course of dose-escalation immunotherapy, we undertook microarray analysis of CD4+ T cells at different the stages of treatment, using Tg4 Rag-1 deficient mice, which lack naturally occurring regulatory T cells and have a monoclonal CD4+ T cell population
