Description
Hematogenous macrophages infiltrate the brain after virus infection. We use a CSF1R inhibitior, PLX5622 to deplete microglia from the brain. However, macrophages also express the CSF1R and may be affected by PLX5622-treatment of mice.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
IL-10 is an anti-inflammatory cytokine that has been shown to be produced by antigen-specific CD8 T cells at the peak of viral encephalitis. We found that IL-10+CD8 T cells are more activated and cytolytic than IL-10-CD8 T cells.

Description
West Nile virus (WNV) is the most important cause of endemic encephalitis in the USA. Strikingly, only a small percentage of patients develop clinical disease and of these patients, approximately 1 out of 150 patients develops encephalitis. The basis for this great variability in disease outcome is unknown, but may be related to the innate immune response. Innate immune responses, critical for control of WNV infection, are initiated by signaling through pathogen recognition receptors (PRR) such as RIG-I and MDA5. IPS-1 is a key adaptor in generating a PRR-dependent interferon response.. Here we show that IPS-1 deficiency in hematopoietic cells resulted in increased mortality and delayed WNV clearance from the brain. In IPS-1-/- mice, a dysregulated immune response was detected, characterized by a massive influx of macrophages and virus-specific T cells into the infected brain. These T cells were multifunctional and were able to lyse peptide-pulsed target cells in vitro. However, virus-specific T cells in the infected IPS-1-/- brain exhibited lower functional avidity than those in C57BL/6 brains, possibly contributing to less efficient virus clearance. The presence of virus-specific memory T cells was also not protective. We also show that macrophages were increased in numbers in the IPS-1-/- brain. Both macrophages and microglia exhibited an activated phenotype. Microarray analyses showed the preferential upregulation of genes associated with leukocyte activation and inflammation. Together, these results demonstrate the critical role that hematopoietic cell expression of Type 1 interferon and other IPS-1-dependent molecules have in WNV clearance and in regulating the inflammatory response.

Description
Gene expression profile studies have identified an interferon signature in whole blood or mononuclear cell samples from patients with systemic lupus erythematosus. This study was designed to determine whether specific lymphocyte and myeloid subsets freshly isolated from the blood of systemic lupus erythematosus patients demonstrated unique gene expression profiles compared to subsets isolated from healthy controls.

Illumina HiSeq 2000
Description
Aim: Transcriptional analysis of the duodenum of adult Nkx2.2flox/SD;Villin-Cre (SDint) mice versus control Methods: 2 cm of the duodenum (as measured from the stomach) of 6 week old control and mutant mice were dissected and total RNA extracted. Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 20 million reads were mapped to the mouse genome (UCSC/mm9) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq. Results: 206 genes with a p-value <0.05 were significantly changed. Among these are some enteroendocrine hormones. Conclusion: The SD domain of Nkx2.2 regulates specification of some enteroendocrine cells Overall design: mRNA profiles of the duodenum of 6 week old control and SDint mice were generated by deep sequencing, in triplicate, using Illumina HiSeq2000.

Description
Aim: Transcriptional analysis of the colon of adult Nkx2.2flox/flox;Villin-Cre (Nkx2.2int) mice versus control Methods: 2 cm of the colon (as measured after the caecum) of 6 week old control and mutant mice were dissected and total RNA extracted. Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 20 million reads were mapped to the mouse genome (UCSC/mm9) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq. Results: 53 genes with a p-value <0.05 were down-regulated and 36 were up-regulated. Among the changed genes are enteroendocrine hormones. Conclusion: Nkx2.2 regulates enteroendocrine cell specification Overall design: mRNA profiles of the colon of 6 week old control and Nkx2.2int mice were generated by deep sequencing, using Illumina HiSeq2000.

Description
We ovexpressed human alpha synuclein alone or together with Nurr1 in mouse primary midbrain cultures and identified the full spectrum of genes whose expression is affected by alpha synuclein, including genes whose expression is normalized after Nurr1 overexpression. Moreover we treated mouse primary midbrain cultures with Bexarotene or short hairpin RNA fro Nurr1, sorted out the dopamine neurons and assessed the effects of Bexarotene and of the Nurr1 downregulation on gene expression. Overall design: Comparison of 3 Synuclein samples to 5 controls (RFP), Comparison of 3 Synuclein + Nurr1 samples to 5 controls (RFP), Comparison of 3 Bexarotene samples to 3 controls (DMSO), comparison of 1 short hairpin against Nurr1 to 1 control (scrambled).
