Project description:Analysis of interferon-stimulated genes (ISGs) in various primary cells and immortalized cell lines, following type 1 interferon (IFN) treatment. Some cell types become resistant to HIV-1 infection following type 1 interferon treatment (such as macrophages, THP-1, PMA-THP-1, U87-MG cells and to a lesser extent, primary CD4+ T cells) while others either become only partially resistant (e.g., HT1080, PMA-U937) or remain permissive (e.g., CEM, CEM-SS, Jurkat T cell lines and U937); for more information see (Goujon and Malim, Journal of Virology 2010) and (Goujon and Schaller et al., Retrovirology 2013). We hypothesized that the anti-HIV-1 ISGs are differentially induced and expressed in restrictive cells compared to permissive cells and performed a whole genome analysis following type 1 IFN treatment in cell types exhibiting different HIV-1 resistance phenotypes. 48 samples; design: 9 cell lines, primary CD4+ T cells and primary macrophages, untreated and IFN-treated; 2 replicate experiments per cell line; 3 replicate experiments per primary cell type

Project description:The transcriptional response to interferon alpha is cell type specific. To data, majority of investigations of interferon alpha induced gene expression have been made using immortalized or transformed cell lines underlining interferon's importance for treatment of cancer but omitting physiological relevance. Here in we have determined gene expression change in primary culture of hepatocytes after interferon alpha treatment. We used Affymetrix Rat Genome 230 2 microarrays to determine gene expression profiles in primary rat hepatocytes after interferon alpha treatment and untreated cells.

Project description:Genome wide RNA-Seq screen was did to detect gene expression. We used immortalized bone-marrow-derived macrophages cells that were uninfected or infected with HSV-1 for 6 hours to detect the expression levels of genes, and we found that interferon stimulated genes were increased and some of genes that inhibit interferon production were decreased in HSV-1 infected iBMDMs, compared to wild-type iBMDMs. we choose some genes that are unknown about their functions on antiviral innate immunity, and adress how they participate in antiviral innate immunity.

Project description:We undertook a unbiased genome-wide haploid genetic screen to identify new components in interferon lambda signaling. In addition, we performed a genome-wide screen to identify genes that repress spontaneous activation of interferon stimulated genes in the absence of interferon. Both of these screens were performed using a HAP1 cell line containing GFP reporter under the transcriptional regulation of the Interferon-Stimulated Response Element from IFIT2. We also overexpressed IL28RA (IFNLR1) in this cell line, in order to sensitize the cells to type III interferon

Here in we have determined gene expression change in primary culture of hepatocytes after interferon alpha treatment. We used Affymetrix Rat Genome 230 2 microarrays to determine gene expression profiles in primary rat hepatocytes after interferon alpha treatment and untreated cells. Primary hepatocytes were chosen because they are most relevant to physiological state in intact liver. Hepatocytes was isolated from rat liver using collagenase treatment procedure and purified on percoll gradient. Next day after isolation primary hepatocytes culture was cultivated with (or without) 250u/ml rat interferon alpha for 3 and 6 hours. Experiment was performed in 3 biological replicates. cRNA preparation was performed according manufacturer's recommendation from 5ug of total RNA and gene expression profiles were determined.

Project description:The cellular response to interferon (IFN) is essential for antiviral immunity, IFN-based therapy and IFN-related disease. The plasma membrane (PM) provides a critical interface between the cell and its environment, and is the initial portal of entry for viruses. Nonetheless, the effect of IFN on PM proteins is surprisingly poorly understood, and has not been systematically investigated in primary immune cells. Here, we use multiplexed proteomics to quantify IFNα-stimulated PM protein changes in primary human CD14+ monocytes and CD4+ T cells from five donors, quantifying 606 and 482 PM proteins respectively. Comparison of cell surface proteomes revealed a remarkable invariance between donors in the overall composition of the cell surface from each cell type, but a marked donor-to-donor variability in the effects of IFNα. Furthermore, whereas only 2.7% of quantified proteins were consistently upregulated by IFNα at the surface of CD4+ T cells, 6.8% of proteins were consistently upregulated in primary monocytes, suggesting that the magnitude of the IFNα response varies according to cell type. Amongst these differentially regulated proteins, we found the viral target Endothelin-converting enzyme 1 (ECE1) to be an IFNα-stimulated protein exclusively upregulated at the surface of CD4+ T cells. We therefore provide a comprehensive map of the cell surface of IFNα-stimulated primary human immune cells, including previously uncharacterised interferon stimulated genes (ISGs) and candidate antiviral factors.

Project description:Collaborative Cross (CC) mouse embryonic fiborolasts (MEF) cells obtained from the eight Founder animals [PWK/PhJ, NZO/HILtJ, NOD/ShiLtJ, WSB/EiJ, A/J, CAST, C57BL/6J, and 129/SvlmJ] were immortalized and the cell lines used to assess differences in transcriptional responses following treatment with type I, II and III recombinant mouse interferon. We collected transcriptome profiles for 8 CC MEF cell lines stimulated with either IFN-α or IFN-β for a total of 16 different biological conditions. Treated and mock samples were collected at 18 hr post-treatment and RNAs extracted and subjected to microarray.

Project description:Genome-wide analysis of dihydrotestosterone (DHT) induced changes in gene expression in primary and immortalized human corneal epithelial cells. Analysis of regulation of primary and immortalized human corneal epithelial cells by dihydrotestosterone at gene expression level. The hypothesis tested in the present study was that the androgen-eye interaction in ocular surface epithelial cells like corneal cells is influenced by androgens through regulation of the expression of multiple genes. Results provide important information of the differential regulation and comparitive analysis of numerous genes in response to dihydrotestosterone incubation in primary and immortalized human corneal epithelial cells.
