Project description:This study aimed to characterize differential responses between the relatively resistant (Fayoumi) and susceptible (Leghorn) chicken lines when challenged with a high titered lentogenic Newcastle Disease Virus (NDV) strain via the eyes and nostrils at three weeks of age. The lung was collected from challenged and non-challenged birds from each line at 2, 6, and 10 days-post-infection (dpi). High quality RNA was isolated, used for cDNA library construction, and sequenced on the HiSeq2500.

Project description:BackgroundNewcastle disease virus (NDV) is a threat to poultry production worldwide. A better understanding of mechanisms of resistance and susceptibility to this virus will improve measures for NDV prevention and control. Males and females from resistant Fayoumi and susceptible Leghorn lines were either challenged with a lentogenic strain of the virus or given a mock infection at 3 weeks of age. The lung transcriptomes generated by RNA-seq were studied using contrasts across the challenged and nonchallenged birds, the two lines, and three time points post-infection, and by using Weighted Gene Co-expression Network Analysis (WGNCA).ResultsGenetic line and sex had a large impact on the lung transcriptome. When contrasting the challenged and nonchallenged birds, few differentially expressed genes (DEG) were identified within each line at 2, 6, and 10 days post infection (dpi), except for the more resistant Fayoumi line at 10 dpi, for which several pathways were activated and inhibited at this time. The interaction of challenge and line at 10 dpi significantly impacted 131 genes (False Discovery Rate (FDR) <0.05), one of which was PPIB. Many DEG were identified between the Fayoumi and Leghorns. The number of DEG between the two lines in the challenged birds decreased over time, but increased over time in the nonchallenged birds. The nonchallenged Fayoumis at 10 dpi showed enrichment of immune type cells when compared to 2 dpi, suggesting important immune related development at this age. These changes between 10 and 2 dpi were not identified in the challenged Fayoumis. The energy allocated to host defense may have interrupted normal lung development. WGCNA identified important modules and driver genes within those modules that were associated with traits of interest, several of which had no known associated function.ConclusionsThe lines' unique response to NDV offers insights into the potential means of their resistance and susceptibility. The lung transcriptome shows a unique response to lentogenic NDV compared to a previous study on the trachea of the same birds. It is important to analyze multiple tissues in order to best understand the chicken's overall response to NDV challenge and improve strategies to combat this devastating disease.

Project description:Whole transcriptome analysis of two genetically distinctinct inbred chicken lines during NDV infection and heat stress. Background: Newcastle disease virus, in its most pathogenic form, threatens the livelihood of rural poultry farmers where there is a limited infrastructure and service for vaccinations to prevent outbreaks of the virus. Previously reported studies on the host response to Newcastle disease in chickens have not examined the disease under abiotic stressors, such as heat, which commonly experienced by chickens in regions such as Africa. The objective of this study was to elucidate the underlying biological mechanisms that contribute to disease resistance in chickens to the Newcastle disease virus while under the effects of heat stress. Results: Differential gene expression analysis identified genes differentially expressed between treated and non-treated birds across three time points (2, 6, and 10 days post-infection) in Fayoumi and Leghorn birds. Across the three time points, Fayoumi had very few genes differentially expressed between treated and non-treated groups at 2 and 6 days post-infection. However, 202 genes were differentially expressed at 10 days post-infection. Alternatively, Leghorn had very few genes differentially expressed at 2 and 10 days post-infection but had 167 differentially expressed genes at 6 days post-infection. Very few differentially expressed genes were shared between the two genetic lines, and pathway analysis found unique signaling pathways specific to each genetic line. Conclusions: The findings in this study confirmed our hypothesis that the Fayoumi line was more resistant to Newcastle disease virus infection compared to the Leghorn line. Fayoumi had significantly lower viral load, higher viral clearance, higher anti-NDV antibody levels, and fewer viral transcripts detected compared to Leghorns. Fayoumis activated immune related pathways including SAPK/JNK and p38 MAPK signaling pathways at earlier time points, while Leghorn would activate these same pathways at a later time. Further analysis revealed activation of the GP6 signaling pathway that may be responsible for the susceptible Leghorn response. Interaction analysis demonstrated substantial differences in response patterns between the two genetic lines that was not observed from the within line contrasts. This study has provided novel insights into the transcriptome response of the Harderian gland tissue during Newcastle disease virus infection while under heat stress utilizing a unique resistant and susceptible model.

Project description:Newcastle disease (ND) affects a few hundred avian species including chicken, and the clinical outcome of Newcastle disease virus (NDV) infection ranges from mild to severe fatal disease depending on the NDV pathotype and the host species involved. Japanese quails serve as natural reservoirs of NDV and play important role in NDV epidemiology. While infection of chicken with velogenic NDV results in severe often fatal illness, the same infection in Japanese quails is results in in apparent infection. The molecular basis of this contrasting clinical outcomes of NDV infection is not yet known. We compared global gene expression in spleens of chicken and Japanese quails infected with a lentogenic or velogenic NDVs. We found contrasting regulation of key genes associated with NF-κB pathway and T-cell activation between chicken and Japanese quails. Our data suggests association of NDV resistance in Japanese quails to activation of NF-κB pathway and T cell proliferation.

Project description:Newcastle disease virus (NDV) has a devastating impact on poultry production in developing countries. This study examined the transcriptome of tracheal epithelial cells from two inbred chicken lines that differ in NDV susceptibility after challenge with a high-titer inoculum of lentogenic NDV. The Fayoumi line had a significantly lower NDV load postchallenge than the Leghorn line, demonstrating the Fayoumi line's classification as a relatively NDV-resistant breed. Examination of the trachea transcriptome showed a large increase in immune cell infiltration in the trachea in both lines at all times postinfection. The pathways conserved across lines and at all three time points postinfection included iCOS-iCOSL signaling in T helper cells, NF-κB signaling, the role of nuclear factor of activated T cells in the regulation of the immune response, calcium-induced T lymphocyte apoptosis, phospholipase C signaling, and CD28 signaling in T helper cells. Although shared pathways were seen in the Fayoumi and Leghorn lines, each line showed unique responses as well. The downregulation of collagen and the activation of eukaryotic translation initiation factor 2 signaling in the Fayoumis relative to the Leghorns at 2 days postinfection may contribute to the resistance phenotype seen in the Fayoumis. This study provides a further understanding of host-pathogen interactions which could improve vaccine efficacy and, in combination with genome-wide association studies, has the potential to advance strategies for breeding chickens with enhanced resistance to NDV.

Project description:A unique, lymphoid tissue located adjacent to the eye of the chicken, the Harderian gland is assumed to have critical immune functions, but prior to the current study, its transcriptome had never been analyzed. This study aimed to characterize differential responses between the relatively resistant (Fayoumi) and susceptible (Leghorn) chicken lines when challenged with a high titered lentogenic Newcastle Disease Virus (NDV) strain via the eyes and nares at three weeks of age. The Harderian gland was collected from challenged and non-challenged birds from each line at 2, 6, and 10 days-post-infection (dpi) (n=47). High quality RNA was isolated, used for cDNA library construction, and sequenced on the HiSeq2500.
