Abstract
The Third International Workshop on Lymphocyte Alloantigens of the Horse was held on 25-27 April 1984 in Kennett Square, Pennsylvania. Twelve laboratories from five countries participated. The principal purpose of this Workshop was to determine the phenotypic and gene frequencies of the 10 equine lymphocyte antigens (ELA) and a non-ELA lymphocyte antigen, ELY-2.1, in several breeds of horse. A total of 86 alloantisera characterized in previous workshops were tested against lymphocytes from 1179 horses. In addition, several experimental antisera were also tested against the same panel of lymphocytes. As a result of analysis of these data, the Workshop recognized two new equine lymphocyte alloantigens: W11 of the ELA system, and ELY-1.1, an antigen not linked to the ELA system.

Abstract
Granuloma formation is a form of delayed-type hypersensitivity requiring CD4(+) T cells. Granulomas control the growth and dissemination of pathogens, preventing host inflammation from harming surrounding tissues. Using a murine model of Mycobacterium bovis strain bacillus Calmette-Guérin (BCG) infection we studied the extent of T cell heterogeneity present in liver granulomas. We demonstrate that the TCR repertoire of granuloma-infiltrating T cells is very diverse even at the single-granuloma level, suggesting that before granuloma closure, a large number of different T cells are recruited to the lesion. At the same time, the TCR repertoire is selected, because AND TCR transgenic T cells (Valpha11/Vbeta3 anti-pigeon cytochrome c) are preferentially excluded from granulomas of BCG-infected AND mice, and cells expressing secondary endemic Vbeta-chains are enriched among AND cells homing to granulomas. Next, we addressed whether TCR heterogeneity is required for effective granuloma formation. We infected 5CC7/recombinase-activating gene 2(-/-) mice with recombinant BCG that express pigeon cytochrome c peptide in a mycobacterial 19-kDa bacterial surface lipoprotein. A CD4(+) T cell with a single specificity in the absence of CD8(+) T cells is sufficient to form granulomas and adequately control bacteria. Our study shows that expanded monoclonal T cell populations can be protective in mycobacterial infection.

Abstract
Progressive granuloma formation is a hallmark of chronic mycobacterial infection. Granulomas are localized, protective inflammatory reactions initiated by CD4+ T cells, which contribute to control of bacterial growth and blockade of bacterial dissemination. In order to understand the costimulatory requirements that allow CD4+ T cells to directly or indirectly induce granulomas, we studied granuloma formation after 6 weeks in Mycobacterium bovis BCG-infected CD28- and CD40 ligand (CD40L)-deficient mice and compared it to granuloma formation in infected wild-type inbred mice and infected cytokine-deficient mice. We characterized granulomas morphologically in liver sections, analyzed granuloma infiltrating cells by flow cytometry, and measured cytokine production by cultured granuloma cells. CD28-deficient mice have no defect at the local inflammatory site, inasmuch as they form protective granulomas and control bacterial growth. However, there are fewer activated T cells in the spleen compared to infected wild-type animals, and quantitative differences in the cellular composition of the granuloma are observed by flow cytometry. In CD40L-deficient mice, the granuloma phenotype is very similar to the phenotype in gamma interferon (IFN-gamma)-deficient mice. Both IFN-gamma-deficient and CD40L-deficient mice form granulomas which prevent bacterial dissemination, but control of bacterial growth is significantly impaired. The relative proportion of CD4+ T cells in granulomas from both CD28(-/-) and CD40L(-/-) mice is significantly decreased compared with wild-type animals. Both models demonstrate that the phenotype and activation stage of systemic T cells do not always correlate with the phenotype and activation stage of the localized granulomatous response.

Abstract
The impact of the United Network for Organ Sharing mandatory sharing policy on a large transplant center procuring kidneys primarily from caucasians while serving a pool of prospective recipients composed mainly of blacks is described. This policy requires that all 6-antigen-matched and phenotypically identical donor kidneys be shipped to the appropriately matched recipients. The study consisted of 49 kidneys from 25 cadaveric donors; one kidney was unusable. In general, the 33 recipients of the mandatorily shared kidneys were caucasian (94%), unsensitized (70%), and first-time transplants (73%). Allograft survival for the 24 first-time recipients was 100% (mean graft survival = 11.3 months). Of the 9 regraft kidneys, 2 have failed (mean graft survival = 11.9 months) due to chronic rejection. In comparison, the 16 paired kidneys transplanted into non-6-antigen-matched recipients exhibited a 1-year graft survival of 80% versus 92% for the 33 recipients of mandatorily shared kidneys (P = 0.01). These 16 recipients were composed of more blacks (38%), fewer regrafts (6%), and most were unsensitized (75%). All 25 cadaveric donors were caucasians with very common HLA types. Thus, kidneys provided by the UNOS mandatory sharing policy had excellent allograft survival, and the recipients were largely unsensitized caucasians receiving their first kidney. The low number of blacks receiving allografts under this policy may be due to two factors. First, the histocompatibility differences between black recipients and the primarily caucasian cadaveric donor pool limit the number of kidneys available to blacks. Secondly, blacks do not have access to the best-matched kidneys, in part due to few black donors, their best source for well-matched kidneys. Thus, the mandatory sharing program is of clear benefit to the recipients of these well-matched kidneys; however, for a local program servicing a waiting list composed of 64% blacks the policy has been of limited value. In contrast, over 50% of local cadaveric transplants are into black recipients in a waiting time of 197 days, one third the national average for blacks. In conclusion, this study supports efforts to improve graft survival through matching but emphasizes the need to broaden our efforts in all areas of research and organ procurement to serve the entire recipient population, regardless of race.

Abstract
An avian thymic hormone, originally designated the T1-antigen, was purified from chicken thymus by Sephadex G-75-40 chromatography and affinity chromatography, following enrichment by heat and pH treatments. It was characterized as an acidic polypeptide rich in phenylalanine, alanine and serine, lacking in histidine, tryptophan, methionine and cysteine, and having a blocked N-terminal amino acid. The hormone also was rich in hydrophobic amino acid residues, which gave it a propensity to form aggregates. Its molecular weight was estimated by gel electrophoresis and low speed sedimentation equilibrium to be 12-13 Kd, and by molecular sieving chromatography to be 15-16 Kd. The hormone was lacking in carbohydrates and amino sugars.

Abstract
Graft survival was examined in 15 renal allograft recipients from a group of 20 patients with IgM autolymphocytotoxic antibody that could be removed in a crossmatch assay using a reducing agent, dithioerythritol (DTE). The significant differences in this group of 20 patients compared with end-stage renal disease (ESRD) patients lacking autolymphocytotoxic antibodies included an increased frequency of black patients (P = 0.002), a lack of previous transplants (P = 0.003), and an increased frequency of the HLA-DR1 phenotype (P = 0.0001). Sex and the number of transfusions did not appear significant, whereas the cause of ESRD was primarily systemic lupus erythematosus. Fifteen of the 20 patients were transplanted against a positive donor crossmatch. Eleven were recipients of cadaveric kidneys, nine of which are still functioning for periods ranging from 0.5 to 40 months. Two fo the cadaveric recipients died with functional grafts. Four received living-related donor transplants, one of which was lost to acute rejection one month posttransplant, while the remaining three have survived 1.5, 9, and 21 months, respectively. Fourteen patients had immediate allograft function with no hyperacute rejection and only one case of acute tubular necrosis (ATN) was found. In summary, a negative crossmatch using DTE-treated, autologous reactive recipient sera may identify a group of patients who can be transplanted with minimal concern for hyperacute rejection or ATN. In addition to cause of ESRD, race, transplant history, and HLA-DR phenotype may further define this group of transplant candidates having IgM autolymphocytotoxic antibody. Extrapolation of these conclusions to transplant candidates lacking autolymphocytotoxic antibodies is not warranted.

Abstract
Recent reports have shown an association between genes lying within the major histocompatibility complex (MHC), particularly HLA and factor B (Bf), and acute lymphocytic leukemia (ALL) in white children. The frequencies of Bf and complement component C4 phenotypes in 90 black American children with ALL were examined to determine if a genetic association existed. The Bf and C4 results for the black children with ALL were compared with frequencies in healthy black Americans from the same geographic region. The BfF allele was carried by 95.6% of the black ALL patients compared with 86.1% of the controls (P = 0.017; relative risk = 3.5). In contrast, only 2.2% of the patients with ALL were homozygous for BfS compared with 9.8% of the controls (P = 0.043; relative risk = 0.2). These findings are similar to those observed in white American children. The C4A6 phenotype was found in 11.9% of the black children with ALL compared with 0.6% of the controls (P = 0.0026; relative risk = 22.7). These findings represent the first reported association of a particular allele whose gene lies within the MHC with ALL in black American children. The results suggest that the occurrence of ALL in black American children may be partially due to a genetic influence.
