Project description:To investigate specific miRNA expression profiles of Marek's disease virus (MDV)-infected samples, we performed deep sequencing for miRNAs in four small RNA libraries, including MDV-infected tumorous spleen, MD lymphoma from liver, and non-infected spleen and lymphocytes from controls. A total of 7.76x106, 6.36x106, 6.36x106, and 7.60x106 counts were obtained in four libraries, respectively. The sequences were blasted with chicken and MDV genomes and miRBase 16.0 to identify known and novel miRNAs. In total, 187 and 16 known mature miRNAs were identified in the chicken and MDV, respectively. Deep sequencing detected 942 novel chicken miRNA candidates, of which 646 were in tumorous spleen. These results indicate that MDV infection induced new host miRNA candidates and increased diversity of miRNAs. Of 942 miRNA candidates, 276 of 533 were verified by customized microarray, and 17 of them were further confirmed by qPCR. Four samples examined: MDV-infected tumorous spleen, MD lymphoma from liver, Non-infected spleen, Non-infected lymphocytes

Project description:To gain more insight into the molecular mechanisms of the tumorigenesis of MDV, we used microarrays to screen host and viral miRNAs that were sensitive to infection by MDV. Microarray analysis showed significant differential expression of 79 miRNAs, To determine whether miRNAs were involved in the MDV-induced tumorigenesis, miRNA microarray analysis was performed on GA-infected splenic tumors, GA-infected non-tumorous spleen tissues, and control spleen tissues at 28 dpi.

Project description:The existence of conventional dendritic cells (cDCs) has not yet been demonstrated outside mammals. In this paper, we identified bona fide cDCs in chicken spleen. Comparative profiling of global and of immune response gene expression, morphology, and T cell activation properties show that cDCs and macrophages (MPs) exist as distinct mononuclear phagocytes in chicken, resembling their human and mouse cell counterparts. Using computational analysis, core gene expression signatures for cDCs, MPs, T and B cells across chicken, human and mouse were established, which will facilitate the identification of these subsets in other vertebrates. Overall this study, by extending the newly uncovered cDC and MP paradigm to chicken, suggests that the generation of these two phagocyte lineages occurred before the reptile to mammal and bird transition in evolution. It opens avenues for the design of new vaccines and neutraceuticals that are mandatory for the sustained supply of poultry products in the expanding human population.

Four independent replicates of RNA from 4 cellular populations have been purified from histocompatible chicken spleens, based on surface markers and fluorecence cell sorting: putative conventional Dendritic cells (F2+, MHC-II+ cells) ; control B cells (BU-1+ cells; only 3 replicates could be included in the study); T cells (CD3+ cells) and macrophage spleen population (MHC-II+, KUL-01+ cells).

Project description:Chicken 60-mer oligonucleotide microarray, including 39854 cDNA and ESTs, entire Marek’s disease virus and avian influenza virus genomes, and 150 chicken microRNAs, was developed. Cecal tonsil, ileum, liver and spleen from 6 chickens were selected for hybridization to validate the microarray performance. There are 2886, 2886, 2660, 358, 3208 3355, and 3710 genes significantly expressed between liver and spleen, spleen and cecal tonsil, cecal tonsil and ileum, liver and cecal tonsil, liver and ileum, spleen and ileum at the P<10-7. Number of tissue specific genes for cecal tonsil, ileum, liver and spleen was 95, 71, 535, and 108, respectively with p < 10-7. More than 95% of spots had high SNR (>10).

Project description:Marek's disease virus (MDV) strain GX0101 was the first reported field strain of recombinant gallid herpesvirus type 2 (GaHV-2). However, the splenic proteomics study of MDV strain GX0101 infected chicken was still unclear. In this study, GX0101 was used to infect the chicken spleen in order to analyze the splenic proteomics of the chicken after GX0101 infection.
