Abstract
Abstract
The tightly linked A and E blood alloantigen systems are 2 of 13 blood systems identified in chickens. Reported herein are studies showing that the genes encoding A and E alloantigens map within or near to the chicken regulator of complement activation (RCA) gene cluster, a region syntenic with the human RCA. Genome-wide association studies, sequence analysis, and sequence-derived single-nucleotide polymorphism information for known A and/or E system alleles show that the most likely candidate gene for the A blood system is C4BPM gene (complement component 4 binding protein, membrane). Cosegregation of single-nucleotide polymorphism–defined C4BPM haplotypes and blood system A alleles defined by alloantisera provide a link between chicken blood system A and C4BPM. The best match for the E blood system is the avian equivalent of FCAMR (Fc fragment of IgA and IgM receptor). C4BPM is located within the chicken RCA on chicken microchromosome 26 and is separated from FCAMR by 89 kbp. The genetic variation observed at C4BPM and FCAMR could affect the chicken complement system and differentially guide immune responses to infectious diseases.

Abstract
Recombination within the chicken major histocompatibility complex (MHC) has enabled more precise identification of genes controlling immune responses. Chicken MHC genes include BF, MHC class I; BL, MHC class II; and BG, MHC class IV that are closely linked on chromosome 16. A new recombination occurred during the 10th backcross generation to develop congenic lines on the inbred Line UCD 003 (B17B17) background. Recombinant R13 (BF17-BG23) was found in a single male chick from the Line 003.R1 (BF24-BG23) backcross. An additional backcross of this male to Line UCD 003 females increased the number of R13 individuals. Two trials tested this new recombinant for antibody production against the T cell-dependent antigen, bovine red blood cells. Fifty-one progeny segregating for R13R13 (n = 10), R13B17 (n = 26), and B17B17 (n = 15) genotypes were produced by a single R13B17 male mated to 5 R13B17 dams. One milliliter of 2.5% bovine red blood cell was injected intravenously into all genotypes at 4 and 11 wk of age to stimulate primary and secondary immune responses, respectively. Blood samples were collected 7 d after injection. Serum total and mercaptoethanol-resistant antibodies against bovine red blood cell were measured by microtiter methods. The least squares ANOVA used to evaluate all antibody titers included trial and B genotype as main effects. Significant means were separated by Fisher's protected least significant difference at P < 0.05. R13R13 chickens had significantly lower primary total and mercaptoethanol-resistant antibodies than did the R13B17 and B17B17 genotypes. Secondary total and mercaptoethanol-resistant antibodies were significantly lower in R13R13 chickens than in R13B17 but not B17B17 chickens. Gene differences generated through recombination impacted the antibody response of R13 compared with B17. Secondary antibody titers were not substantially higher than the primary titers suggesting that the memory response had waned in the 7-wk interval between injections. Overall, the results suggest that the lower antibody response in R13R13 homozygotes may be caused by recombination affecting a region that contributes to higher antibody response.

Abstract
Alloantigen systems are a broad group of molecules found on various cell types, including erythrocytes and lymphocytes. These alloantigens, identified via specific polyclonal or monoclonal antibodies or molecular methods, have demonstrated effects on immune responses. Erythrocyte alloantigens include the A, B, C, D, E, H, I, J, K, L, N, P, and R systems. Highly polymorphic alloantigen B has been identified as the chicken major histocompatibility complex (MHC). The other twelve systems have a variable degree of polymorphism as well as impact on immune measurements or responses against pathogens. Selection for immune characters altered allele frequencies for particular alloantigen systems. Three lymphocyte alloantigens, Bu-1, Ly-4 and Th-1 have more limited polymorphism but still influence responses against viral pathogens, Rous sarcoma virus and Marek's disease. Together, these erythrocyte and lymphocyte systems contribute to the overall immunity. Identification of the specific alloantigen proteins remains crucial to understanding their immune contribution.

Abstract
The chicken MHC-B locus affects the response to several strains of Rous sarcoma virus (RSV). We evaluated the association between haplotypes of the MHC-B locus and responses to the J strain of RSV by using an F(2) experimental resource family constructed with tumor-regressive (White Leghorn) and tumor-progressive (Rhode Island Red) chickens. The MHC-B haplotypes were determined by genotyping of the microsatellite marker LEI0258 and MHC-B locus class I alpha chain 2 (BF2). Two haplotypes in the resource family, one associated with tumor regression and one with progression, were defined by these 2 markers. To discriminate more precisely the regressive haplotype in this family, we further developed 35 SNP markers at the MHC-B locus. Information on the haplotypes revealed here should be useful for identifying chickens with regression and progression phenotypes of J-strain RSV-induced tumors.

Abstract
YF1*7.1 is an allele of a polymorphic major histocompatibility complex (MHC) class I-like locus within the chicken Y gene complex. With the aim of understanding the possible role of the YF1*7.1 molecule in antigen presentation, the complex of YF1*7.1 heavy chain and beta(2)-microglobulin was reconstituted and purified without a peptide. Crystals diffracted synchrotron radiation to 1.32 A resolution and belonged to the monoclinic space group P2(1). The phase problem was solved by molecular replacement. A detailed examination of the structure may provide insight into the type of ligand that could be bound by the YF1*7.1 molecule.

Abstract
A variety of methods are available to combat avian diseases in the commercial setting, including improved farm management practices, use of antibiotic drugs, selection of disease resistant chicken strains, and manipulation of the chicken immune system. In the latter category, development of vaccines against the major avian diseases has become a priority for the poultry industry. With increasing demands for developing alternative control programs for many poultry diseases, it is important to understand the basic immunobiology of host-pathogen interactions in order to develop novel vaccination strategies. From studies carried out in many mammalian species, it is evident that host immune responses to intracellular pathogens are complex and involve many components of the host immune system. For enteric pathogens such as Eimeria and Salmonella, understanding cell-mediated immunity is most important because antibodies, although abundantly produced locally, can not access and act on these intracellular pathogens. In poultry, slow but increasing understanding of various components of host immune system mediating cellular immunity is opening new opportunities for thorough investigation of the role of thymus-derived lymphocyte subpopulations and cytokines in normal and disease states. This paper will review recent progress with chicken cytokines that have been characterized, and discuss various experimental strategies to enhance host immunity to pathogens using chicken cytokines.

Abstract
Collaborative research efforts across disciplines typically result in more insight toward the hypothesis being tested due to the omnibus nature of the projects. For example, nutritional experiments evaluating a nutrient response will benefit greatly by incorporating biochemical, physiological, and immunological endpoints for measurement. Clearly, commercial poultry producers do not have the luxury of focusing on specific disciplines when field problems occur. Hence, in practice interplay exists among nutrition, genetics, management, and diseases. Dietary composition impacts immune function of the chicken. As research in the area of nutritional immunology has increased, it is becoming apparent that nutrient needs for immunity do not coincide with those for growth or skeletal tissue accretion. This review is not a comprehensive assessment of nutrient needs for immunity in the chicken. Rather, this review is concerned with nutritional modulation of immunity in broilers that offers insight for nutritionists and researchers to implement nutritional regimens to reduce the severity of disease and to test or validate nutritional regimens that heighten immunity. Nutritional modulation of the hen diet and in ovo nutrient modulation to improve chick immunity and disease resistance are discussed.

Abstract
This study examined alloantigen system L effects on resistance to initial infection and acquired immunity to Eimeria tenella infection in three B complex genotypes. Experimental progeny segregating for B and L genotypes were produced from pedigree matings of B2B5 L1L2 sires and dams. Chicks were weighed and inoculated with 30,000 E. tenella oocysts at 6 wk of age to evaluate resistance in four trials (n = 262). Immunity was studied in four additional trials (n = 244) by immunizing progeny with 500 E. tenella oocysts per day for 5 d beginning at 5 wk of age. Two weeks after the last immunization dose, the birds were weighed and challenged with 30,000 E. tenella oocysts. All birds were weighed again and scored for cecal lesion 6 d after the 30,000 oocyst dose challenge. Weight gain and cecal lesion scores were evaluated by ANOVA. Major histocompatibility (B) complex genotypes B2B2 and B5B5 did not affect resistance to initial challenge with E. tenella based on lesion score and weight gain. However, after immunization, the B5B5 and B2B5 genotypes had significantly lower cecal scores than the B2B2 genotype when the birds were rechallenged. Weight gain was not affected among immunized birds. No significant L system effects with or without immunization were detected. These results are consistent with previous research demonstrating B complex effects on immunity to cecal coccidiosis.

Abstract
This study was designed to examine the alloantigen system L effects on Rous sarcomas in three B complex genotypes. The parental stock was 50% Modified Wisconsin Line 3 x White Leghorn Line NIU 4 and 50% inbred Line 6.15-5. Pedigree matings of two B(2)B(5) L(1)L(2) sires to five B(2)B(5) L(1)L(2) dams per sire produced experimental chicks segregating for B and L genotypes. Chicks were inoculated with 20 pock-forming units (pfu) of Rous sarcoma virus (RSV) at 6 weeks of age. Tumors were scored six times over 10 weeks postinoculation after which the tumor scores were used to assign a tumor profile index (TPI) to each chicken. Tumor growth over time and TPI were evaluated by repeated-measures analysis of variance and analysis of variance, respectively. Six trials were conducted with a total of 151 chickens. The major histocompatibility (B) complex affected the responses as the B(2)B(2) and B(2)B(5) genotypes had significantly lower tumor growth over time and TPI than the B(5)B(5) genotype. Separate analyses revealed no significant L system effect in B(2)B(2) or B(2)B(5) backgrounds. However, L genotype significantly affected (P < 0.05) both tumor growth over time and TPI in B(5)B(5) chickens. B(5)B(5) L(1)L(2) birds had TPI significantly lower than B(5)B(5) L(1)L(1) chickens but not B(5)B(5) L(2)L(2). Mortality was lower in the B(5)B(5) L(1)L(2) birds than in B(5)B(5) L(2)L(2) chickens. The L system, or one closely linked, affects the growth and ultimate outcome of Rous sarcomas. The response may depend upon the genetic background as well as MHC type.

Abstract
Major histocompatibility (B) complex haplotypes B(Q) and B17 were examined for their effect on Rous sarcoma outcome. Pedigree matings of B(Q)B17 chickens from the second backcross generation (BC2) of Line UCD 001 (B(Q)B(Q)) mated to Line UCD 003 (B17B17) produced progeny with genotypes B(Q)B(Q), B(Q)B17, and B17B17. Six-week-old chickens were injected with subgroup A Rous sarcoma virus (RSV). The tumors were scored for size at 2, 3, 4, 6, 8, and 10 weeks postinoculation. A tumor profile index (TPI) was assigned to each bird based on the six tumor scores. Two experiments with two trials each were conducted. In Experiment 1, chickens (n = 84) were inoculated with 30 pock-forming units (pfu) RSV. There was no significant B genotype effect on tumor growth over time or TPI among the 70 chickens that developed tumors. Chickens (n = 141) were injected with 15 PFU RSV in Experiment 2. The B genotype significantly affected tumor growth pattern over time in the 79 chickens with sarcomas. The B(Q)B17 chickens had the lowest TPI, which was significantly different from B17B17 but not B(Q)B(Q). The data indicate complementation because more tumor regression occurs in the B(Q)B17 heterozygote than in either B(Q)B(Q) or B17B17 genotypes at a 15 pfu RSV dose and significantly so compared to B17B17. By contrast, the 30 pfu RSV dose utilized in the first experiment overwhelmed all genotypic combinations of the B(Q) and B17 haplotypes, suggesting that certain MHC genotypes affect the immune response under modest levels of viral challenge.
