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
Th17 cells were sorted ex vivo from PB of healthy donors as CD4+CD161+CCR6+CXCR3-. Following, cells were transduced with a lentiviral vector carrying the Eomes gene or with an empty vector. Infected cells were then enriched by MACS separation using the reporter gene NGFR as selection marker. Finally, cells were frozen for RNA analysis.

Description
The expression of a very large number of genes changes as male germ cells pass through differentiation into spermatids and then sperm. Much of this transcriptional programme requires the activity of the meiotic arrest genes.

Description
The ability of dying cells to activate antigen presenting cells (APCs) is carefully controlled to avoid unwarranted inflammatory responses. Here we show that engulfed cells only containing cytosolic dsDNA species (viral or synthetic) or cyclic di-nucleotides (CDNs) are able to stimulate APCs, via extrinsic STING-signaling.

Description
MIST1 is a bHLH transcription factor that is necessary for the maturation of gastric zymogenic cells as they differentiate from their precursor mucous neck cells. In this experiment, mucous neck cells and zymogenic cells of normal, adult C57BL/6 and MIST1 knockout mice were laser-capture microdissected in order to determine MIST1-dependent, zymogenic cell specific gene expression.

Description
The incidence and mortality rates of prostate cancer are significantly higher in African-American men when compared to European-American men. We tested the hypothesis that differences in tumor biology contribute to this survival health disparity. Using microarray technology, we obtained gene expression profiles of primary prostate tumors resected from 33 African-American and 36 European-American patients. These tumors were matched on clinical parameters. We also evaluated 18 non-tumor prostate tissues from 7 African-American and 11 European-American patients. The resulting datasets were analyzed for expression differences on the gene and pathway level comparing African-American with European-American patients. Our analysis revealed a significant number of genes, e.g., 162 transcripts at a false-discovery rate less than 5%, to be differently expressed between African-American and European-American patients. Using a disease association analysis, we identified a common relationship of these transcripts with autoimmunity and inflammation. These findings were corroborated on the pathway level with numerous differently expressed genes clustering in immune response, stress response, cytokine signaling, and chemotaxis pathways. Furthermore, a two-gene tumor signature was identified that accurately differentiated between African-American and European-American patients. This finding was confirmed in a blinded analysis of a second sample set. In conclusion, the gene expression profiles of prostate tumors indicate prominent differences in tumor immunobiology between African-American and European-American men. The profiles portray the existence of a distinct tumor microenvironment in these two patient groups.
