Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Human umbilical vein endothelial cells (HUVECs) were transduced with either MIY-N1IC (Notch1 intracellular domain) or MIY vector control. The cells were sorted for YFP, and RNA was extracted using Trizol (Invitrogen) and analyzed by the Affymetrix Human Genome U133 Plus 2.0 Array. Results were analyzed using the GCRMA algorithm to identify genes with a minimum of 2-fold induction or reduction. This global gene expression study was used to identify Notch targets in the endothelium.

- Illumina human-6 v2.0 expression beadchip
Description
Previous studies have shown that purified dendritic cells (DCs) have cell-intrinsic, age-dependent differences in their response to TLR stimulation. To delineate which aspects of the age-dependent difference in innate immunity are cell intrinsic vs extrinsic, we searched for global differences to TLR7/8 stimulation in purified adult vs neonatal DC populations. We hypothesize that very few selected cell intrinsic differences in gene expression of key immune genes between these 2 age groups exist, and the bulk would be cell extrinsic differences. The results show that there are age-dependent differences in expression of several key genes involved in the immune response at baseline already. Upon stimulation, we identified a substantially larger fraction of age-dependent differentially expressed genes in conventional than plasmacytoid DCs. Bioinformatics analyses indicate that important immune pathways were significantly differentially expressed in DC subsets between the 2 age groups.

Description
Periodontal infections have been associated with systemic inflammation and risk for atherosclerosis and vascular disease. We investigated the effects of comprehensive periodontal therapy on gene expression of peripheral blood monocytes. Approximately 1/3 of the patients showed substantial changes in expression in genes relevant to innate immunity, apoptosis, and cell signaling. We concluded that periodontal therapy may alter monocytic gene expression in a manner consistent with a systemic anti-inflammatory effect.

Description
Changes in Treg function are difficult to quantify due to the lack of Treg-exclusive markers in humans and the complexity of functional experiments. We sorted naive and memory human Tregs and conventional T cells, and identified genes that identify human Tregs regardless of their state of activation. We developed this Treg signature using Affymetrix human genome U133A 2.0 microarrays.

Description
Perinatal brain injury is a major clinical problem associated with high neonatal mortality and morbidity and an increased risk of life-long chronic disabilities. Despite improved survival rates, the absolute numbers of neurological handicaps of perinatal origin have not decreased. There is currently no pharmacological treatment providing neuroprotction in neonates. As activation of the innate immune response is a key contributing factor to brain injury in both term and preterm infants we investigated the therapeutic potential of novel immunomodulatory innate defence regulator peptides (IDRs) in perinatal brain injury. IDR-1018 significantly reduced the production of inflammatory mediators by LPS-stimulated microglia cells in vitro.

Description
MicroRNAs (miRNAs) repress the expression levels of genes by binding to mRNA transcripts, acting as master regulators of cellular processes. Differential expression of miRNAs has been linked to viral-associated diseases involving members of the hepacivirus, herpesvirus, and retrovirus families. In contrast, limited biological and molecular information has been reported on the potential role of cellular miRNAs in the lifecycle of influenza A viruses (infA). In this study, we hypothesize that elucidating the miRNA expression signatures induced by low-pathogenic swine-origin influenza A virus (S-OIV) pandemic H1N1 (2009) and highly pathogenic avian-origin (A-OIV) H7N7 (2003) infections could reveal temporal and strain-specific miRNA fingerprints during the viral lifecycle, shedding important insights into the potential role of cellular miRNAs in host-infA interactions. Using a microfluidic microarray platform, we profiled cellular miRNA expression in human A549 cells infected with S- and A-OIVs at multiple time-points during the viral lifecycle, including global gene expression profiling during S-OIV infection. Using target prediction and pathway enrichment analyses, we identified the key cellular pathways associated with the differentially expressed miRNAs and predicted mRNA targets during infA infection, including immune system, cell proliferation, apoptosis, cell cycle, and DNA replication and repair. By identifying the specific and dynamic molecular phenotypic changes (microRNAome) triggered by S- and A-OIV infection in human cells, we provide experimental evidence demonstrating a series of temporal- and strain-specific host molecular responses involving different combinatorial contributions of multiple cellular miRNAs. Our results also identify novel potential exosomal miRNA biomarkers associated with pandemic S-OIV and deadly A-OIV-host infection.
