Accomplishments

The following are summary statements on research accomplishments prepared by each investigator and modified and assembled for the purpose of the annual report by the chair. <br /> <br><br /> <br>AL, EWALD-OBJECTIVE 1. AL reported nucleotide sequences of additional B-F and B-L sequences, providing further insight into the polymorphism of the chicken MHC. The pattern of polymorphism is strikingly different between the two class I loci in chicken, B-FI and B-FIV. By comparison with human class I genes, B-FI polymorphism resembles the HLA-C locus whereas B-FIV polymorphism is similar to HLA-A or -B loci, suggesting that chicken B-FI molecules resemble HLA-C molecules in binding a restricted set of antigenic peptides, and in functioning as killer inhibitory receptors. <br /> <br><br /> <br>AR, ERF-OBJECTIVE 2. AR reported on the role of herpesvirus of turkey (HVT) vaccination in autoimmune vitiligo (V) in Smyth line (SL) chickens. It was found that only live HVT could trigger SLV above control levels. Additionally, the vitiligo-inducing effect of HVT in SL chickens was higher in females than in males. A gender effect in SLV was also observed following prolonged treatment with IFN-g where the incidence of vitiligo was 87.5 % and 0% in females and males, respectively. AR also reported that dietary supplementation with E. coli bacterial cell wall powder had beneficial effects on S. enteritidis infection by reducing organ invasion and/or enhancing clearance of SE. <br /> <br><br /> <br>CA, DELANEY-OBJECTIVE 1. CA-Delaney studied telomerase activity profiles of transformed avian (chicken and quail) cells cultured in vitro. Telomerase activity was detected in all transformed cells examined (10 lines) whereas non-transformed cells cultured in vitro showed no or down-regulated activity over time. CA-D completed the molecular characterization of the 5S rDNA array and continues studies on cell surface expression of MHC-encoded antigens (BF, BL, B-G) in chicken embryos (whole or organs) from Stage X (0hr) through day 15 of incubation and on fine-mapping of microchromosome 16 (with CA-Miller)<br /> <br><br /> <br>CA, KLASING-OBJECTIVE 2. CA-Klasing evaluated the role of avidin in limiting the growth of the chicken pathogen S. typhimurium by withholding biotin. Macrophages stimulated with S. typhimurium LPS expressed avidin mRNA and their conditioned medium inhibited the growth of S. typhimurium. This inhibition was reversed by biotin. Acute phase response serum from S. typhimurium LPS injected chickens inhibited S. typhimurium growth and this bacteriostatic property was reversed by biotin. The addition of iron did not increase the proliferation of S. typhimurium in chicken acute phase serum in the absence of biotin. Iron significantly increased proliferation in the presence of biotin. <br /> <br><br /> <br>CA, MILLER-OBJ1. CA-Miller continues to contribute to the physical map of the chicken MHC and to more closely define the gene region(s) that provide resistance to tumor growth following infection with Marek&lsquo;s disease virus. CA-M is building BAC contigs for the Rfp-Y and B regions using the Jungle Fowl BAC libraries made available by Jerry Dodgson as part of the US Poultry Genome Project. One 116kb clone from the Rfp-Y region has been sequenced and analyzed in collaboration with Tokai University. CA-M is completing an analysis of MHC B recombinant haplotypes with the goal defining the crossover points. OBJECTIVE 3: CA-M is completing publication of the proposed standard for MHC nomenclature adopted by the ISAG Avian Immunogenetics Standing Committee.<br /> <br><br /> <br>CA, UCD, WAKENELL-OBJECTIVE 1. To date, CA-Wakenell has not observed the same clinical signs and/or lesions in the scleroderma birds maintained at UCD compared to NIU. Extensive explorative testing is underway to determine whether the skin condition in NIU is scleroderma or may be the result of an environmentally induced condition, perhaps fungal. CA-W conducted 2 Marek&lsquo;s disease (MD, RB1B) pathogenicity trials to further investigate the role of the Y system on MD in chickens with a moderately resistant B background (B2B2, B2B5, B5B5). In Trial 1 12/15 SPF and 25/84 test birds were pos for MD. In Trial 2, 2/15 SPF and 0/59 test birds were pos. Histopathology and Y haplotyping are pending. In addition to MD pathology, CA- initiated clinical chemistry analysis in these trials. OBJECTIVE 3: CA-W continues to conduct serum chemistry analysis with a Kodak DT-60 clinical chemistry analyzer. <br /> <br><br /> <br>DE, EMARA-OBJECTIVE 1. DE has identified single nucleotide polymorphisms (SNPs) in various candidate chicken genes that affect immune response and disease resistance and constructed a SNP database (http://chicksnps.afs.udel.edu/). The SNPs in the MHC class II-associated invariant chain and ovotransferrin genes were confirmed by PCR and sequencing. The SNPs for both of these genes are segregating in MD-challenged experimental populations and their association with MD is being determined. A new growth hormone polymorphism (SNP) was also identified and is being tested in the MD-challenged resource population.<br /> <br><br /> <br>IL, BRILES-OBJECTIVE 1. IL reported the development of cross-line chicks displaying simultaneous segregation of eight alloantigen systems. They are to be made available to interested collaborators to facilitate functional comparisons between heterozygous types. Additionally, SSCP (single stranded conformation polymorphism) assays are being used to establish Rfp-Y haplotypes in NIU chickens. Primers for BF, BL and YF genes produced for chicken have been successfully applied to bobwhite quail DNA for preliminary study of MHC haplotypes in the population. <br /> <br><br /> <br>IA, LAMONT-OBJECTIVE 1. Twenty highly inbred lines of chickens were reproduced, and line purity was verified by serological typing. A F1 outbred broiler X inbred resource population was studied for identification of molecular markers for early vaccine antibody response and for resistance to S. enteritidis colonization in broilers. Associations of INOS, TRAIL, TGFb2, TGFb3, and IgL genes with response to S. enteritiditis in poultry were identified. An F2 Fayoumi X Leghorn resource population was used to investigate associations between genetic markers and antibody production kinetics. A three-step genotype strategy (DNA pooling, selective genotyping, and whole population genotyping) was used to identify microsatellite markers that are associated with the immune response. A third set of resource populations is being produced as advanced intercross lines of broiler by layer and broiler by Fayoumi.<br /> <br><br /> <br>MA, COTTER-OBJECTIVE 2. MA continues to investigate naturally occurring antibody especially the significance of antibody to the galactose epitope (anti-Gal) measured by the agglutination of rabbit erythrocytes. BSA antibodies found by MA and others in unimmunized chickens were not due to diluents used in vaccines. MA is also investigating whether exposure to animal (mouse) feces plays a role in the development of naturally occurring agglutinins. MA also studied the beneficial effects of mannanoligosaccharides on immunity and as growth promoters. <br /> <br><br /> <br>MD, LILLEHOJ-OBJECTIVE 1. In collaboration with DE-Emara, MD identified a quantitative trait Loci (QTL) microsatellite marker associated with coccidiosis disease resistance in commercial broiler chickens. These QTL were detected by a genome wide scan (200 markers) of F2 families consisting of approximately 850 individuals and located to the genomic regions with highly significant associations to specific economically important traits. OBJECTIVE 3: MD cloned and expressed chicken cytokines including IL-15, IL-16 and IL-17 and developed monoclonal antibodies detecting chicken IL-15 and IL-15 receptor alpha to identify chicken cytokine production in serum. These reagents will be used to assess host immune response to coccidia and salmonella.<br /> <br><br /> <br>NH, TAYLOR-OBJECTIVE 1. Among chickens segregating for B and L haplotype combinations, NH found alloantigen L affected ME-resistant secondary antibody titers to BA in B2B5 chickens, but did not affect weight gain or lesion score 6 days post E. tenella challenge. Testing the 1st and 2nd SRBC antibody response using 6 congenic lines containing B complex recombinants (R1-R6) on the Line UCD 003 (B17B17) background revealed differences attributable to the B complex recombinant haplotypes. The SRBC antibody response in B2B2 chickens that had either Y1.2Y4 or Y4Y6 genotypes and 75% of the Line 6 background was not affected by Rfp-Y genotype, however, ME-resistant 2nd antibody titers were higher in Y1.2Y4 than Y4Y6 birds. NH continues production and maintenance of specialized research chickens (6.B congenic lines 6.6-2 (B2B2) and 6.15-5 (B5B5) on the line 61 background; 003.R congenic recombinant chickens containing B complex recombinants (R1-R6) on the Line UCD 003 (B17B17) background; Rfp-Y congenic chickens (Y1.2 and Y6) on Line 6.6-2 and UCD 003; and Line UNH 193 trisomic chickens (B19B19B19)).<br /> <br><br /> <br>NY, DIETERT-OBJECTIVE 2. NY-Dietert used a double injection in ovo model in which testosterone was first injected into the embryo followed later in development by either lead acetate or acetate as a control and found no effects of treatments on hatchability or body weight. Comparison of lead glutamate toxicity on different Marek&lsquo;s disease virus transformed chicken T lymphocyte cell lines (CU 91, CU 94 CU 210 and CU 211) revealed that, unlike in HD11 cells, the highest concentration of lead glutamate used (45.00 mM) failed to produce significant necrosis or apoptosis in the T cell lines. <br /> <br><br /> <br>NY, MARSH (M)-OBJECTIVE 2. NY-Marsh reported that in vivo thymulin treatments given either before or after IBV infection enhanced NK cell activity of the cells recovered by lung lavage. This was a dose-dependent effect. Thymulin treatments made the harvested cells much more responsive to IFN-gamma, resulting in their elevated activation. This is interpreted as an upregulation of IFN receptors on the NK cell population.<br /> <br><br /> <br>NY, SCHAT (S)-OBJECTIVE 1. NY-Schat continued to maintain N2a and P2a flocks and to monitor them for CIAV, which is important if offspring will be used for CMI studies. OBJECTIVE 2: NY-S found that in birds infected with CIAV and a second pathogen, immunosuppression is due to a failure to generate antigen-specific cytotoxic T lymphocytes (CTL). The presence of maternal antibodies prevents the immunosuppressive effects. OBJECTIVE 3: NY-S continued the characterization of MDV glycoproteins that are recognized by cytotoxic T lymphocytes (CTL). In addition to gB, other glycoproteins were also recognized to different degrees by CTL from N2a (B21B21 and MD resistant) and P2a (B19B19 and MD susceptible) chickens. <br /> <br><br /> <br>NC, QURESHI-OBJECTIVE 1. NC reported modern day broilers have reduced adaptive immune responses but normal innate immune responses. To further examine genetic-based differences in immune responses, high (B15B15 Cornell K-strain) and low (B13B13,GB-1; B6B6, GB-2) responders for iNOS gene expression and activity were tested for differences in monocyte/macrophage, T and B lymphocyte functions. The response profiles for these parameters were consistent with that for iNOS expression and activity. OBJECTIVE 2: NC reported that immunizations of breeders with PEMS-associated reovirus (ARV-U98) might protect progeny poults from PEMS-associated liver atrophy. Dietary Beta-1,3/1,6-glucan (b-glucan) was found to upregulate several immune endpoints in chickens.<br /> <br><br /> <br>SC, SCOTT-OBJECTIVE 2. SC reported detection of cytokine activity, both inhibitory and stimulatory in supernatants of homogenized Haderian glands. Electrophoresis and chromatofocusing of the supernatant revealed three major components of the supernatants at 13.5, 14 and 28 kDa with approximate pIs around pH 8.0. Immunization of mice with the supernatant components produced two hybridomas; one producing antibodies to the 13.5 and the other to the 28 kDa component. These antibodies can block the activity in the supernatant.
