Project description:Marek's disease (MD), induced by Marek's disease virus (MDV), is a lymphotropic neoplastic disease and causes huge economic losses to the poultry industry. Non-coding RNAs play important regulatory roles in disease pathogenesis. To investigate host miRNA expression profile, RNA sequencing was performed in tumorous spleens (TS), spleens from the survivors (SS) without any lesion after MDV infection, and noninfected chicken spleens (NS).

Project description:Whole genome resequencing of 125 chicken and two pooled populations including red jungle fowl and multiple populations of commercial broilers and layers
Project description:B lymphocytes from the chicken Bursa of Fabricius were isolated and cultured in the presence of CD40L. Cells were infected with a GFP fluorescent reporter virus of the very virulent Marek's disease virus (vvMDV) strain RB-1B (RB-1B_UL47-GFP, see doi: 10.1073/pnas.1424420112). After 24h viable infected (GFPpositive) and uninfected (GFPnegative) B-cells were sort purified from these cultures. Viable B cells, purified from uninfected cultures served as control. 3x10^6 cells per sample were subjected to RNA isolation and microarray analysis. Goal of the experiment was to elucidate the reaction of chicken B cells, primary target cells of MDV upon infection with this virus.
Project description:Viral diseases pose major threats to humans and other animals, including the billions of chickens that are an important food source as well as a public health concern due to zoonotic pathogens. Unlike humans and other typical mammals, the major histocompatibility complex (MHC) of chickens can confer decisive resistance or susceptibility to many viruses. Examples are Marek's disease virus (MDV) and Infectious bursal disease virus (IBDV). We used a new in vitro infection system and immunopeptidomics to identify peptides presented to T lymphocytes via classical MHC class II molecules.
Project description:We sequenced single cells with the 10x platform of chicken spleens from chickens genetically resistant and genetically susceptible to Marek's disease, with both infected individuals and uninfected controls from both lines
Project description:We infected chickens from two genetic lines, one bred to be resistant to Marek's disease and one bred to be susceptible, with the Marek's disease virus. We performed single-cell RNA sequencing of the spleens of these chickens along with age-matched uninfected controls from both lines.
Project description:Transcriptional profiling of chicken spleen tissues from Marek's disease virus (MDV) infected and non-infected control individuals from three inbred chicken lines 63, 72, RCSM with varying disease resistance characteristics. Line 63 is highly resistant; line 72 is highly susceptible; and line RCSM has intermediate resistance. Our goal was to investigate the genetic basis of systemic variation in disease resistance in these genetically similar individuals. Three time points were chosen at different stages of disease progression - 5 days post-infection (dpi) - early cytolytic phase; 10 dpi - latent phase; and 21 dpi - late cytolytic phase with 4 replicates at each stage.
Project description:This study investigated firstly, the impact of ploidy on growth performance and whole body composition of Atlantic salmon at different early freshwater stages (34 dph (days post-hatching) alevin; 109 dph; fry and 162 dph parr;) and secondly, whether phenotypic differences at these stages were reflected in protein samples collected from whole fish, white muscle or liver tissue. Female diploid and triploid Atlantic salmon (n = 3) were first fed at 35 dph and then maintained by feeding to satiation on commercial feeds.
