RNA-sequencing reveals a distinct transcriptomic signature of chicken embryonic stem cells (cESC) infected with recombinant vaccine vectors

Project description:In this study, we used RNA-sequencing to compare the transcriptional programmes in cESC, elicited either by stimulation with recombinant interferon-α or by infection with the attenuated Fowlpox virus vaccine strain (FP9), the canarypox virus vaccine strain (CNPV), the Modified Vaccinia Ankara (MVA) virus or PBG98, a mild vaccine strain of infectious bursal disease virus.

Kinetics of host transcription in CEFs productively infected with recombinant fowlpox virus vaccine vector FP9

Project description:Fowlpox virus (here as FP9, a plaque-purified, high passage-attenuated derivative) effectively suppresses induction of the âinnateâ immune responses, notably the Type I interferon system, of the permissive host (chicken). Despite the extensive usage of fowlpox virus as a recombinant vaccine vector in chickens, its immunomodulatory mechanisms remain largely unknown. In this study, a transcriptomic analysis using the Affymetrix GeneChip chicken genome array was performed at the host gene transcription level at 4, 8, 16 and 24 hours post-infection of mock treated and FP9-infected (MOI=5, 2h) chicken embryo fibroblasts (CEF). The experiment was performed in triplicate with three different batches of CEFs. Because fowlpox virus is capable of expressing antigens in mammalian cells, these studies in chicken cells form a baseline for subsequent study of immunomodulation of mammalian innate immune responses.

Genome-wide comparison of Chicken Embryo Fibroblasts (CEF) and DF-1 in response to recombinant chicken chIFN-Î± and infection with Infectious Bursal Disease Virus (IBDV)

Project description:The spontaneously immortalised chicken DF-1 cell line is rapidly replacing its progenitor primary chicken embryo fibroblasts (CEF) in studies on avian viruses but no comprehensive study has as yet been reported comparing their immune phenotype. We conducted microarray analysis of the DF-1 and CEF, in both normal and stimulated conditions using recombinant chicken chIFN-Î± and the CEF-adapted infectious bursal disease virus vaccine strain PBG98.

An integrated transcriptome analysis to the characterization of host responses against infectious laryngostracheitis virus vaccine infection in chicken embryo lung cells

Project description:Host gene expression of chicken embryo lung cells infected an infectious laryngotracheitis virus (ILTV) vaccine strain comparing control uninfected lung cells. Goal was to identify the changes of host gene expression by ILTV vaccine infection. Two-condition experiment, uninfected chicken embryo lung cells vs. vaccine infected chicken embryo lung cells. Biological replicates: 1 control uninfected sample, 1 vaccinal ILTV infected experimental sample at each 1, 2, 3 and 4 dpi.

Transcriptome analysis reveals an activation of MHC-I and MHC-II pathways in chicken trachea immunized with infectious laryngotracheitis virus vaccine

Project description:Infectious laryngotracheitis (ILT) is an acute, contagious, upper respiratory disease, which is caused by gallid herpesvirus 1 (GaHV-1). Due to the mortality rates up to 70% depending on the virulence of the virus, it is of economic importance of the disease to explore the etiology of the ILT in the poultry industry. In this study, 15-day-old SPF white leghorn chickens were used to transcriptome analysis in chicken trachea immunized with infectious laryngotracheitis virus vaccine. In conclusion, chicken embryo origin (CEO) vaccine activation of the MHC-I and MHC-II pathways provides insight into the molecular mechanism of immune response in chickens, and holds potential for evaluation and design of new ILT vaccines in a manner adapted to the host immune response to the virus. Ten vaccine inoculated birds were randomly divided in two groups. Each group represents one replication of five pooled tissues, for inoculated birds. Control group consists of five birds that received sterile vaccine diluent.

<b>Chicken Embryonic-Stem Cells Are Permissive to Poxvirus Recombinant Vaccine Vectors</b>.

Project description:The discovery of mammalian pluripotent embryonic stem cells (ESC) has revolutionised cell research and regenerative medicine. More recently discovered chicken ESC (cESC), though less intensively studied, are increasingly popular as vaccine substrates due to a dearth of avian cell lines. Information on the comparative performance of cESC with common vaccine viruses is limited. Using RNA-sequencing, we compared cESC transcriptional programmes elicited by stimulation with chicken type I interferon or infection with vaccine viruses routinely propagated in primary chicken embryo fibroblasts (CEF). We used poxviruses (fowlpox virus (FWPV) FP9, canarypox virus (CNPV), and modified vaccinia virus Ankara (MVA)) and a birnavirus (infectious bursal disease virus (IBDV) PBG98). Interferon-stimulated genes (ISGs) were induced in cESC to levels comparable to those in CEF and immortalised chicken fibroblast DF-1 cells. cESC are permissive (with distinct host transcriptional responses) to MVA, FP9, and CNPV but, surprisingly, not to PBG98. MVA, CNPV, and FP9 suppressed innate immune responses, while PBG98 induced a subset of ISGs. Dysregulation of signalling pathways (i.e., NFκB, TRAF) was observed, which might affect immune responses and viral replication. In conclusion, we show that cESC are an attractive alternative substrate to study and propagate poxvirus recombinant vaccine vectors.

Transcriptomic analysis of attenuated Salmonella Typhimurium infected chicken primary macrophages

Project description:Salmonella enterica is one of the most important foodborne pathogens that infect a variety of animals and birds. In humans, S. Typhimurium causes gastroenteritis, leading to vomiting, diarrhea, fever, and abdominal cramps. We mainly get infected with Salmonella by ingesting comminated poultry products. Therefore, developing an oral live attenuated vaccine for the poultry industry is our best bet against Salmonella infection. In this article, we investigated the potential of the next generation of Salmonella vaccines. We generated a library of potentially attenuated S. Typhimurium mutants and compared fitness to that of a commercial vaccine. We also investigated the invasion and survival potential of these mutants in chicken macrophages. Our data indicate that although these mutants had no significant growth defects, they were much sensitive to macrophage attack. Analyzing the transcriptome data from infected primary chicken macrophages, we concluded that these mutants elicit a robust immune response by activating several immunoregulatory pathways. Our data also indicates that by combining phoPQ deletion with an already existing cya-crp deletion in MeganVac1, a much stronger immune response can be generated.

The effects of novel adjuvant complex and CpG ODN on host immune response to recombinant Eimeria profilin vaccine

Project description:This study investigated the ability of two novel adjuvant formulations, QCDC (Quil A/cholesterol/DDA/Carbopol) and QCDCR (QCDC/Bay R1005), in combination with a recombinant profilin vaccine, to modulate host protective immunity and to alter new gene expression during experimental avian coccidiosis.
