Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
IL-27 has been shown to play a role in modulating functions of diverse cell types like Th1, Th2, NK and B cells demonstrating both pro and anti-inflammatory roles. It is also capable of inducing STAT1, STAT3 and ISG's. To investigate the role of IL-27 on hepatocytes, Huh7.5 cells were treated with Il-27 and analysed the differentially expressed genes by microarray analysis.

Illumina Genome Analyzer II
Description
Purpose: To investigate the quaternary structures of Rhodopsin-family GPCRs. Method: Analyzed 60 receptors from HEK 293T cells. Results: 1) Most of these receptors are monomers. 2) The phylogenetic distribution of dimers suggests that monomers have an evolutionary advantage due to constraints imposed by dimerization on rates of receptor diversification. Overall design: To investigate the quaternary structures of 60 Rhodopsin-family GPCRs expressed in HEK 293T cells using type-1 and -3 BRET assays.

Description
Following exposure to vaccines, antigen-specific CD8+ T-cell responses develop as long-term memory pools. Novel vaccine strategies based on adenoviral vectors, e.g. those developed for HCV, are able to induce and sustain substantial CD8+ T-cell populations. How such populations evolve following vaccination remains to be defined at a transcriptional level. We addressed the transcriptional regulation of divergent CD8+ T-cell memory pools induced by an adenoviral vector encoding a model antigen (beta-galactosidase). We observe transcriptional profiles that mimic those following infection with persistent pathogens, murine and human cytomegalovirus (CMV). Key transcriptional hallmarks include up-regulation of homing receptors, and anti-apoptotic pathways, driven by conserved networks of transcription factors, including T-bet (TBX21). In humans, a novel adenovirus vaccine induced similar CMV-like phenotypes and underlying transcription factor regulation. These data clarify the core features of CD8+ T-cell memory following vaccination with adenovirus vectors and indicate a conserved pathway for memory development shared with persistent herpesviruses.

Description
Diffuse large B-cell lymphoma (DLBCL) represents the most common form of lymphoma. We could show that in DLBCL cell lines the transcription factor NFAT is constitutively activated and drives the survival of a DLBCL subset. Aim of the analysis was to identify NFAT target genes in a NFAT-dependent (HBL-1) or -independent (HT) DLBCL cell line. To block NFAT activity, the DLBCL cells were treated with the calcineurin inhibitor cyclosporin A (CsA) up to 48 h. With this approach, we identified several survival-related NFAT target genes in HBL-1 cells that might explain the toxic effects of calcineurin inhibitors.

Description
Exhausted T cells express multiple co-inhibitory molecules that impair their function and limit immunity to chronic viral infection. Defining novel markers of exhaustion is important both for identifying and potentially reversing T cell exhaustion. Herein, we show that the ectonucleotidse CD39 is a marker of exhausted CD8+ T cells. CD8+ T cells specific for HCV or HIV express high levels of CD39, but those specific for EBV and CMV do not. CD39 expressed by CD8+ T cells in chronic infection is enzymatically active, co-expressed with PD-1, marks cells with a transcriptional signature of T cell exhaustion and correlates with viral load in HIV and HCV. In the mouse model of chronic Lymphocytic Choriomeningitis Virus infection, virus-specific CD8+ T cells contain a population of CD39high CD8+ T cells that is absent in functional memory cells elicited by acute infection. This CD39high CD8+ T cell population is enriched for cells with the phenotypic and functional profile of terminal exhaustion. These findings provide a new marker of T cell exhaustion, and implicate the purinergic pathway in the regulation of T cell exhaustion.
