Accomplishments

Broadbent

Objective 2: We investigated agents and mechanisms affecting poultry immune health, focusing on infectious bursal disease virus (IBDV) and avian reovirus (ARV). Recent work in the Delmarva region identified a novel IBDV variant with mutations in the hypervariable region (HVR) of the capsid gene, particularly four mutations (S254N, S317R, G322E, E323D) that significantly reduce the virus’s neutralization by antibodies targeting the common Delaware-E strain, indicating a potential immune escape variant circulating locally. Additionally, the innovative use of chicken intestinal organoids has provided insight into ARV pathogenesis, revealing that distinct ARV strains elicit different immune responses; for example, an enteritis-causing strain led to elevated inflammatory cytokines and reduced intestinal barrier integrity, highlighting strain-specific immune challenges. These findings enhance understanding of immune evasion and variability in disease outcomes in poultry, aiding in the design of targeted vaccines and treatments.

Objective 3. We aim to enhance immune function and disease resistance in poultry by developing and utilizing genetic tools and assays. Researchers have built a novel reverse genetics system and B-cell neutralization assay for antigenic characterization of infectious bursal disease virus (IBDV), enabling precise assessment of how specific mutations in the hypervariable region affect antibody neutralization and revealing that sequence data alone inadequately reflects antigenic differences. In addition, newly established intestinal organoids derived from chickens, turkeys, and ducks are now used to analyze and compare species-specific mucosal immune responses to enteric viruses, supporting efforts to understand interspecies immune variation and improve vaccine efficacy.

Cotter

Objective 3: This research identifies unique cytological behaviors and mitotic capabilities in thrombocytes and plasmacytes that expand our understanding of avian immune cells. Observations of thrombocyte mitosis, an unusual phenomenon, suggest that fully differentiated thrombocytes may revert to mitotic states under stress. Thrombocytes were also shown to undergo shape changes and cytoplasmic shedding, producing thromboplastids, which parallel erythroplastids in erythrocytes, highlighting adaptive responses. Additionally, plasmacytes were categorized by RNA hue, with derived and dwarf types observed, the latter potentially representing hypodiploid cells linked to truncated IgY production in waterfowl. Finally, the analysis of Mott-type plasmacytes revealed polyploid characteristics and distinct cytoplasmic inclusions (Russell bodies), challenging conventional cell differentiation theories. These findings contribute to understanding immune cell plasticity and potential responses to pathology.

Drechsler, Ng, Sparling

Objectives: 1: Developing a project on Cluster Homolog Immunoglobulin-like Receptors in the chicken (CHIR). Phylogenetic analysis and re-annotation of CHIR submitted to NCBI. Preliminary data with siRNA shows effects on CHIR-B. Single-cell sequencing of the shell gland shows differences in cellular populations and CHIRs in B2 and B19 haplotypes.

Objective 3: Continuation of functional annotation of the chicken genome: RNA-sequencing, ATAC-sequencing, Cut&Taq-sequencing, and whole genome bisulfite sequencing (WGBS) of 20 tissues/cells have been completed. DNA methylome completed for reproductive and intestinal tissues/ peripheral immune cells. RNA seq was completed for all tissues and peripheral blood cells. ATAC seq was completed using a new methodology for better quality and smaller cell populations due to issues with QC previously. ChIP seq with new methodology is close to completion. A supplemental article on the functional annotation of the chicken genome was published in the Journal of Animal Science in 2023.

Erf

Objective 2. Studies on multifactorial, non-communicable disease using the UCD200/206 disease models, provided new insights into autoimmune pathology and revealed aberrant innate immune responses, especially to Gram+-bacteria, as well as altered primary and secondary, cellular- and humoral-immune responses to live herpesvirus of turkey vaccines in the UCD-scleroderma model. Evaluation of the local (GF-pulp) and systemic (blood) cellular responses, as well as systemic antibody-responses to different formulations, preparations, and dosages of a first and second administration of killed Salmonella vaccines, demonstrated heterophil dominated, T cell-dependent, immune responses.

Objective 3: AR maintained and reproduced genetic lines that spontaneously develop autoimmune diseases. AR refined and expanded the use of the growing feather as an in vivo test-tube system to study innate and adaptive immune responses in poultry. The combination of the in vivo test tube with blood sampling proved effective in evaluating the effects of genetic selection and nutrition on innate immune system development and function.

Gallardo

Objective 3: Understand the pathobiology of IBV causing FLS in laying hens.

Hauck

Objective 2: This study investigates how infections with coccidia and avian reoviruses (ARV) interact within chicken cell models and influence immune responses. Using chicken embryo liver (CELi), kidney (CEK), and macrophage (HD11) cell lines, cells were inoculated with ARV and analyzed at various time points for viral loads and gene expression changes. Viral loads were highest in CELi cells, with differential gene expression (DEGs) most prominent in HD11 cells at 12 hours, CEK at 8 hours, and CELi at 24 hours post-inoculation. Pathway analysis highlighted cell type-specific responses: organ development in HD11, blood clotting in CEK, and interferon and cytokine signaling in CELi. These findings provide insight into cell-specific immune responses and the molecular interplay between ARV and the host.

Hearn

Objective 1: Single-cell sequencing has been performed to analyze immune cell composition, infection response and transcriptional regulation of MD-resistant, susceptible and F1 hybrid chickens; animal studies have been performed to identify MHC and non-MHC genetic resistance to IBDV and ILTV infection; large-scale transmission experiments have been performed to analyze influence of vaccination, host genetics, and viral mutation rate on MDV transmission and evolution; flow-sorted samples have been obtained for TCR repertoire sequencing of MHC-congenic chicken CTLs.

Objective 2: Polyclonal antisera to chicken PD-1 and PD-L1 have been developed and tested in vivo for effects on MD pathogenesis and survival

Objective 3: Single-cell sequencing for a multi-organ chicken immune atlas has been performed and analyzed; RNA probe-based immune cell immunophenotyping is in progress; ADOL genetic chicken lines have been transferred to USNPRC and are being maintained.

Jarosinski

Objective 1: Cloned and sequenced innate immune genes from MD-resistant and -susceptible chickens.

Objective 2: Cloned potential MDV gC interacting partners to test in co-immunoprecipitation assays and tested purinergic receptor expression during MDV infection.

Objective 3: We have cloned the putative chicken CR1, CR2, C3, and C4 and generated mAbs for CR1 and CR2.

Lamont

Objective 1: Progress was made in defining genetic control of response to various pathogens in chickens.

Objective 3: ISU chicken genetic lines were reproduced and maintained and shared for collaborative research.

Nazmi

Objective 3: This study investigates the role of intraepithelial lymphocytes (IEL) in chickens during necrotic enteritis (NE), a condition caused by the co-infection of Eimeria maxima and Clostridium perfringens. Sixty-three specific-pathogen-free chickens were divided into control, Eimeria maxima (EM), and Eimeria maxima + Clostridium perfringens (EM/CP) groups. The EM/CP group exhibited subclinical NE, lower body weight gain, and shorter colon lengths. Significant changes in IEL populations were observed one day after C. perfringens infection, with the EM/CP group showing increased natural IEL subsets. By seven days post-infection, some IEL populations remained elevated. The EM/CP group also had higher levels of pro-inflammatory cytokines in the jejunum, suggesting that these IEL play a crucial protective role in the immune response against C. perfringens during subclinical NE.

Parcells

Objective 1: From a practical standpoint, we found that vIL8 is a virulence determinant in the context of HVT.

Objective 2: We found that BRG1 binds the C-terminus of vv+MDVs and is dependent on the mutations found at specific positions common to mutation (PPPP->P(Q/A)PP) and that this binding confers increased transcriptional activation.

Objective 3: We found that EZH2 is constitutively expressed in PBMC and therefore its activity on the MDV genome may be regulated by histone demethylases.

Selvaraj

Objective 3: A study evaluated the efficacy of two killed Salmonella bacterin vaccine, administered intramuscularly- in layers. The first vaccine had 97% S. typhimurium and 3% Immune Plus® with preservatives and adjuvants. The second vaccine was synthesized with 77% S. typhimurium, 10% Klebsiella strain KP9580, 10% Klebsiella strain KPZBT01, and 3% Immune Plus® with preservatives and adjuvants. These results indicate that the killed bacterin vaccine produces an increase in serum antibody titer and could be a potential viable vaccine candidate against Salmonella infection in layers.

Taylor

Objective 1.  Individual or pooled DNA having defined alloantigen genotypes analyzed with 600k SNP enabled the identification of systems A, D, E, and I which are C4BPM, CD99, FCAMR, and RHCE, respectively. Systems H and L have been found on chromosomes 24 and 4, respectively. Their gene identification remains in progress. Selection for high (HAS) and low (LAS) antibody response to sheep red blood cells had different impacts on PBL and spleen mRNA expression of cytokines and chemokines. LAS peripheral blood leukocytes had higher IL6 but no difference in IL4, IL10, CXCL8, CCL4, or TGF-4 compared with HAS. HAS spleen cells had higher IL4 and CXCL8 but no difference in IL6, IL10, CCL4, or TGF-4 compared with LAS. Selection for antibody response to sheep red blood cells resulted in different growth patterns and relative weights of the spleen and bursa of Fabricius. HAS spleens grew faster than LAS spleens. LAS bursae were smaller than HAS bursae through 63 days of age. One hundred fifty protein-encoding genes on Chromosome 31 were identified as CHIRs Cluster Homolog of Immunoglobulin-like Receptors (CHIRs). These large transmembrane glycoproteins that direct the immune response include functional groups CHIRA, CHIRB, and CHIRAB which are putatively activating, inhibitory, or dual function, respectively. Over 1000 diverse and rare CHIRs variants associated with differential Marek’s disease response (P < 0.05) emphasize the impact of CHIRs on shaping avian immune responses in diverse contexts.

Objective 3: West Virginia University (WVU) maintained genetic stocks are typed at the MHC and other alloantigen systems. The stocks, available for collaborative projects include two inbred lines, four congenic lines and five different line crosses. Alloantisera produced by Dr. W. E. Briles at Northern Illinois University (NIU) are held by WVU. This resource includes 243 alloantisera reacting against 74 different antigens, across most alloantigen systems.

Zhou

Objective 2: This study examines mucosal immune responses to avian influenza virus (AIV) in the Harderian gland (HG) of two genetically distinct chicken lines: the Fayoumi, which is relatively resistant to AIV, and the Leghorn, which is more susceptible. Chickens from both lines were inoculated with low pathogenic avian influenza (LPAI) H6N2, and various immune parameters were assessed through viral titers, tissue analysis, and flow cytometry. Findings revealed that Fayoumi chickens exhibited a higher percentage of macrophages and less severe symptoms compared to Leghorns by day four post-inoculation. Leghorns had increased MHC class II expression on macrophages and B cells, despite having fewer macrophages overall. Ongoing analyses, including single-cell RNA sequencing and spatial gene expression profiling, aim to identify genetic factors that confer resistance in Fayoumi chickens. Ultimately, this research seeks to enhance understanding of host resilience to AIV, thereby reducing disease impact and improving poultry industry sustainability.

Impacts

  1. Broadbent Objective 2: It is important to identify novel variants of IBDV that are currently circulating, to determine whether vaccines should be updated. We identified a novel variant in the Delmarva region and demonstrated that 4 mutations present in the HVR led to a reduction in antibody binding. This information will be valuable to companies making IBDV vaccines. Objective 3: It is difficult to assess whether an ARV isolated from a chicken with enteritis is the primary cause, or whether it is a bystander infection not contributing to the enteritis. It may be possible to use primary organoids to screen isolates to evaluate if they cause enteritis or not. The organoids can also be used to study the mucosal immune response of the avian intestine to infection with enteric viruses.
  2. Cotter Objective 3: A demonstration of thrombocyte mitosis is the first report of a property of a cell now known to be important in innate and acquired immunity.
  3. Drechsler, Ng, Sparling Objective 1: Establishing the role of chicken immunoglobulin-like receptors will benefit agricultural and human research. This study will further understand immunoglobulin-like receptors in disease resistance in MHC-defined chickens, providing producers with genetic biomarkers for enhanced immunity against diseases through selective breeding. Objective 3: Functionally annotating the chicken genome will benefit research on agricultural animals. Uncovering the location of regulatory elements and determining their interactions will provide the necessary framework to understand how regulatory networks govern gene expression and how genetic and environmental influences alter these networks to impact animal growth, health, and disease susceptibility or resistance.
  4. Erf Objective 2: Association of altered innate responses with autoimmune disease development and immunopathology provides insight into the regulation and function of the immune system in poultry. Studies on cellular and humoral responses to vaccines and vaccine components is important for the development of effective and safe vaccines. Understanding the influence of nutrition and environmental conditions on immune system development and function improves poultry production and health management. Objective 3: The autoimmune disease-prone Smyth, UCD-200/206 and Obese strain chickens are important genetic models to study the cause-effect relationship between genetic susceptibility, immune function, and environmental factors in multifactorial, non-communicable diseases affecting poultry and humans. The growing feather “in vivo test-tube” system together with blood sampling is an effective, minimally invasive two-window approach for the simultaneous examination of cellular and systemic immune responses, over time, in an individual.
  5. Gallardo Objective 3: The understanding of the origin of FLS in laying hens gives us insights on the use of antibodies early in the chick’s life, to prevent the clinical issue.
  6. Hauck Objective 2: A better understanding of how different cell types respond to infection with ARV is the first step in the identification of biomarkers for ARV infections. It is laying the groundwork for future experiments into the pathogenesis of ARV infections that will allow a more targeted testing of intervention methods.
  7. Hearn Objective 1: Mechanisms of MHC- and non-MHC genetic resistance to poultry pathogens are being examined at the levels of immune cell composition, transcriptional regulation, and receptor diversity, and effects on disease response and pathogen transmission are being studied, which will aid development of both genetic and vaccine-based disease control methods. Objective 2: Determining the effects of the PD-1/PD-L1 T cell signaling pathway on MD pathology may offer novel targets for genetic resistance or new vaccine adjuvantation platforms. Objective 3: Development of a chicken immune cell atlas, RNA-based methods for bioassaying immune cell markers, and maintenance of critical genetic stocks will aid basic and applied avian immunology research needed to meet ongoing poultry disease challenges.
  8. Jarosinski Objective 1: Identifying cellular interacting partners for MDV gC could significantly impact vaccine design and therapies to prevent MDV infection. Objective 2: Identifying a cell receptor would have a major impact on controlling MD. Objective 3: Understanding the mechanisms involved in how avian herpesviruses (pathogenic and vaccines) transmit from chicken to chicken will help generate better vaccines and the genetic selection of chicken lines.
  9. Lamont Objective 1: Identification of structural and functional genetic variants associated with differential responses to pathogens laid the foundation for future studies and for genetic selection to improve disease resistance in poultry. Objective 3: Continued research with ISU chicken genetic lines was enabled.
  10. Nazmi Objective 3: Our results indicate that innate immune cells (iCD8a and non-T cells (CD3neg IEL) and innate-like immune cells (TCRgd and TCRabCD8aa IEL) play a crucial role in protecting the mucosal barrier against NE induced by C. perfringens.
  11. Parcells Objective 1: Understanding the genetic basis of disease resistance in poultry, particularly in the context of Marek's disease (MD) is significant. By characterizing the role of exosomes in immune suppression and vaccine responses, as well as investigating the effects of specific genes like SATB1 and vIL8 on vaccine efficacy, this research provides valuable insights into how genetic factors influence disease outcomes. Ultimately, these findings could guide the development of more effective vaccines and breeding strategies to enhance disease resistance in poultry populations. Objective 2: It is crucial for advancing our understanding of how environmental, dietary, and physiological factors influence the immune development and disease resistance of poultry. By investigating the role of splice variant-derived Meq proteins in Marek’s disease virus (MDV) pathogenesis and the evolutionary mechanisms behind MDV virulence, this research sheds light on the fundamental processes that affect disease susceptibility. These insights could inform the development of targeted strategies to enhance immune function and resilience in poultry, ultimately improving disease management and production efficiency in the industry. Objective 3: to enhance poultry production efficiency by developing methodologies and reagents that assess immune function and disease resistance. Cloning and expressing key chicken genes will provide vital tools for studying immune responses and protein interactions. This will support genetic selection efforts, leading to improved disease resilience and productivity in poultry.
  12. Selvaraj Objective 3: Developed a killed vaccine, that will not cause liver disease in layers, for Salmonella.
  13. Taylor Objective 1: Identifying alloantigen genes, their products as well as their associations with economic traits will facilitate genetic improvement and benefit stakeholders. Objective 3: Defined genetic stocks will enhance discovery of gene products that have direct or indirect impact important commercial traits.
  14. Zhou Objective 2: We identified genetic variants associated with enhanced resistance to AI, which will have a significant impact on the poultry industry.
