Project description:With the purpose to elucidate the expression changes of host genes of SPF chickens infected with duck-origin H7N9 subtype avian influenza virus at 24 hours post-infection(hpi) and fowl adenovirus-4 at 48 dpi. The spleens of SPF chickens infected with duck-origin H7N9 subtype avian influenza virus and fowl adenovirus-4 were collected and high throughout sequenced. Compared with the control group, there were 2426 differentially expressed genes were obtained in the duck-origin H7N9 subtype avian influenza virus group, including 913 up-regulated genes and 1513 down-regulated genes, and there were 1534 differentially expressed genes were obtained in the fowl adenovirus-4 group, including 632 up-regulated genes and 902 down-regulated genes.
Project description:We infected HD11 macrophages with Salmonella Typhimurium, followed by chemical proteomic analysis of deubiquitinases by using ubiquitin-specific active-site probe.
Project description:We used LPS-stimulated chicken HD11 macrophage-like cell as a model to identify the key transcription factors involved in transcriptome regulation responsible for SeMC treatment. RNA-seq identified 3,263 transcripts significantly differentially expressed between the SeMC treated group and the control group, and 1,344 transcripts significantly differentially expressed between LPS+SeMC and LPS treated group (FDR < 0.05, FDR > 1.5). Bioinformatic analysis revealed that six transcription factors, NFKB2, RFX2, E2F5, ETV5, BACH1, and E2F7 were candidate genes for transcriptome regulation in SeMC treated HD11 cells.
Project description:We used LPS-stimulated chicken HD11 macrophage-like cell as a model to identify the key transcription factors involved in transcriptome regulation responsible for Procyanidin B1 treatment. RNA-seq identified 1,384 transcripts significantly differentially expressed between the Procyanidin B1 treated group and the control group, and 696 transcripts significantly differentially expressed between LPS+Procyanidin B1 and LPS treated group (FDR < 0.05, FDR > 1.5). Bioinformatic analysis revealed that five transcription factors, FOSL1::JUND, CREB1, ZNF467, STAT2, and HIF1A were candidate genes for transcriptome regulation in Procyanidin B1 treated HD11 cells.
Project description:Human monocyte-derived macrophage cells were infected with Chikungunya virus (CHIKV) to identify and quantify intracellular transcriptional changes that contribute to the host response to infection with CHIKV. RNA was collected from these cells at 8 and 24 hours post-infection (hpi) and were compared to mock-infected cells. The RNAseq data was then analyzed to determine the genes, functions, and signaling pathways that were significantly affected in an effort to predict existing drugs that could be repurposed as potential therapeutics for CHIKV.
Project description:HD11 cells were stimulated with 1 ug/ml endotoxin from ST-798 for 1, 2, 4 and 8 hours Cells were harvested at 1, 2, 4 and 8 hrs post stimulation and RNA was isolated from these cells and microarray was conducted for these RNA samples using affymetrix genechips
Project description:In order to elucidate the infection mechanisms of Eimeria tenella and the chicken immune response, chicken macrophage cell cultures of cell line HD-11 were infected with Eimeria tenella strain Hougton sporozoites. Samples were taken at 0, 2, 4, 12, 24, 48 and 72 hours post-infection and, purified and mRNA sequenced. A dual-RNA seq analysis was carried out, comparing the expression of infected chicken macrophages with uninfected ones at the same time points post-infection and comparing E. tenella samples during the infection with a sample of pure sporozoites. The results show a variety of response signals in the chicken, both previously known and unknown, as well as a clear role for different sets of SAG and MIC proteins for sporozoites and merozoites of E. tenella
Project description:Chikungunya virus (CHIKV) infection is characterized by alterations in gene expression profile on host cells that consequently lead to an immune response. Here, we used RNA sequencing to analyze the mRNA expression profile in human monocyte-derived macrophages (MDMs) infected with a Colombian clinical isolate of CHIKV at 6 and 24 hpi. analyze the mRNA expression profile in the human monocyte-derived macrophages infected at 6 and 24 hrs with a Colombian clinical isolate of Chikungunya virus.
Project description:This study is planned to characterize the proteome profile of HPAI H5N1 virus infected chicken lung tissues to identify the molecular pathogenesis and proteomic determinant associate with disease progression in susceptible host.
