Abstract
Correction of anemia with erythropoietin (EPO) is associated with improved kidney transplant outcomes. Emerging evidence, predominantly from animal models, indicates that these observations may be erythropoiesis-independent and that EPO exhibits immunosuppressive properties. We examined the effects of EPO on human T-cell alloimmunity by first documenting that CD4(+) and CD8(+) T cells express EPO receptor (EPO-R) on their surfaces. In mixed lymphocyte reactions, EPO induced a dose-dependent decrease in allogeneic CD4(+) T-cell proliferation (EPO 1000 U/ml: 44.6%±22.9% of vehicle, P<0.05; 2000 U/ml: 11.1%±4% of vehicle, P<0.001) without inducing cell death. The effects required signals transmitted directly through the EPO-R expressed on T cells, resulting in diminished Th1 differentiation without effects on regulatory T-cell induction. Mechanistic studies revealed that EPO prevented IL-2-induced proliferation by uncoupling IL-2 receptor signaling, inhibiting phosphorylation of the intracellular intermediaries AKT and extracellular signal-regulated kinase that are known to mediate T-cell expansion. EPO treatment reduced expansion of human naïve CD4(+) T cells after adoptive transfer into NOD scid γc(null) mouse recipients, verifying the effects in vivo. Although activated T cells expressed CD131, an alternative EPO receptor, addition of a specific CD131 agonist peptide, ARA290, did not alter T-cell proliferation or cytokine production. Our findings link EPO-R signaling on T cells to inhibition of T-cell immunity, providing one mechanism that could explain the observed protective effects of EPO in kidney transplant recipients.

Abstract
Maturation of T cell-activating APCs directly links innate and adaptive immunity and is typically triggered by microbial infection. Transplantation of allografts, which are sterile, generates strong T cell responses; however, it is unclear how grafts induce APC maturation in the absence of microbial-derived signals. A widely accepted hypothesis is that dying cells in the graft release "danger" molecules that induce APC maturation and initiate the adaptive alloimmune response. Here, we demonstrated that danger signals associated with dying cells are not sufficient to initiate alloimmunity, but that recognition of allogeneic non-self by the innate immune system is required. In WT as well as in T cell-, B cell-, and innate lymphoid cell-deficient mice, allogeneic grafts elicited persistent differentiation of monocytes into mature DCs that expressed IL-12 and stimulated T cell proliferation and IFN-γ production. In contrast, syngeneic grafts in the same mice elicited transient and less pronounced differentiation of monocytes into DCs, which neither expressed IL-12 nor stimulated IFN-γ production. In a model in which T cell recognition is restricted to a single foreign antigen on the graft, rejection occurred only if the allogeneic non-self signal was also sensed by the host's innate immune system. These findings underscore the importance of innate recognition of allogeneic non-self by monocytes in initiating graft rejection.

Abstract
Intravenous immunoglobulin (IVIg), a therapeutic preparation containing pooled human immunoglobulin (Ig) G, has been suggested to inhibit differentiation and maturation of dendritic cells (DCs); however, controversies exist on this issue. We aimed to reinvestigate the effects of IVIg on human DC maturation and cytokine production, and to determine whether an artifactual determinant is involved in the observed effects. Human monocyte-derived DCs or freshly isolated blood myeloid DCs were cultured in the presence of IVIg in vitro, and the expression of maturation markers CD80, CD86, CD83, and Human Leukocyte Antigen-DR were determined by flow cytometry, whereas production of interleukin (IL)-12 and IL-10 was measured by enzyme-linked immunosorbent assay, and T-cell stimulatory capacity was determined in cocultures with allogeneic CD4(+) T cells. Interestingly, we observed that IVIg did not inhibit, but instead stimulated, spontaneous maturation and T-cell stimulatory ability of human DCs, while leaving lipopolysaccharide-induced DC maturation and cytokine production unaffected. Strikingly, prevention of IVIg binding to culture plate surface, or blocking of the activating Fcγ receptor IIa on DC, abrogated the stimulatory effect of IVIg on costimulatory molecule expression and on T-cell stimulatory capacity of DCs, suggesting that IVIg activates DCs on IgG adsorption to the plastic surface. This study warrants for careful study design when performing cell culture studies with IVIg to prevent artifactual effects, and shows that IVIg does not modulate directly costimulatory molecule expression, cytokine production, or allogeneic T-cell stimulatory capacity of human DCs.

Abstract
Lymph nodes (LNs) are integral sites for the generation of immune tolerance, migration of CD4⁺ T cells, and induction of Tregs. Despite the importance of LNs in regulation of inflammatory responses, the LN-specific factors that regulate T cell migration and the precise LN structural domains in which differentiation occurs remain undefined. Using intravital and fluorescent microscopy, we found that alloreactive T cells traffic distinctly into the tolerant LN and colocalize in exclusive regions with alloantigen-presenting cells, a process required for Treg induction. Extracellular matrix proteins, including those of the laminin family, formed regions within the LN that were permissive for colocalization of alloantigen-presenting cells, alloreactive T cells, and Tregs. We identified unique expression patterns of laminin proteins in high endothelial venule basement membranes and the cortical ridge that correlated with alloantigen-specific immunity or immune tolerance. The ratio of laminin α4 to laminin α5 was greater in domains within tolerant LNs, compared with immune LNs, and blocking laminin α4 function or inducing laminin α5 overexpression disrupted T cell and DC localization and transmigration through tolerant LNs. Furthermore, reducing α4 laminin circumvented tolerance induction and induced cardiac allograft inflammation and rejection in murine models. This work identifies laminins as potential targets for immune modulation.

Abstract
Donor T cells that respond to host alloantigens following allogeneic bone marrow transplantation (BMT) induce graft-versus-host (GVH) responses, but their molecular landscape is not well understood. MicroRNAs (miRNAs) regulate gene (mRNA) expression and fine-tune the molecular responses of T cells. We stimulated naive T cells with either allogeneic or nonspecific stimuli and used argonaute cross-linked immunoprecipitation (CLIP) with subsequent ChIP microarray analyses to profile miR responses and their direct mRNA targets. We identified a unique expression pattern of miRs and mRNAs following the allostimulation of T cells and a high correlation between the expression of the identified miRs and a reduction of their mRNA targets. miRs and mRNAs that were predicted to be differentially regulated in allogeneic T cells compared with nonspecifically stimulated T cells were validated in vitro. These analyses identified wings apart-like homolog (Wapal) and synaptojanin 1 (Synj1) as potential regulators of allogeneic T cell responses. The expression of these molecular targets in vivo was confirmed in MHC-mismatched experimental BMT. Targeted silencing of either Wapal or Synj1 prevented the development of GVH response, confirming a role for these regulators in allogeneic T cell responses. Thus, this genome-wide analysis of miRNA-mRNA interactions identifies previously unrecognized molecular regulators of T cell responses.

Abstract
Naturally occurring FOXP3(+) CD4(+) Treg have a crucial role in self-tolerance. The ability to generate similar populations against alloantigens offers the possibility of preventing transplant rejection without indefinite global immunosuppression. Exposure of mice to donor alloantigens combined with anti-CD4 antibody induces operational tolerance to cardiac allografts, and generates Treg that prevent skin and islet allograft rejection in adoptive transfer models. If protocols that generate Treg in vivo are to be developed in the clinical setting it will be important to know the origin of the Treg population and the mechanisms responsible for their generation. In this study, we demonstrate that graft-protective Treg arise in vivo both from naturally occurring FOXP3(+) CD4(+) Treg and from non-regulatory FOXP3(-) CD4(+) cells. Importantly, tolerance induction also inhibits CD4(+) effector cell priming and T cells from tolerant mice have impaired effector function in vitro. Thus, adaptive tolerance induction shapes the immune response to alloantigen by converting potential effector cells into graft-protective Treg and by expanding alloreactive naturally occurring Treg. In relation to clinical tolerance induction, the data indicate that while the generation of alloreactive Treg may be critical for long-term allograft survival without chronic immunosuppression, successful protocols will also require strategies that target potential effector cells.

Abstract
The aim of this study was to investigate the immune regulatory effect of dendritic cells phagocytosing photochemotherapy-treated allogeneic spleen lymphocytes on syngeneic T cells. DA rat spleen lymphocytes were treated with 8-methoxypsoralen plus UVA irradiation (PUVA). LEW rat bone marrow-derived DCs were co-cultured with PUVA-treated DA spleen lymphocytes (PUVA-SP), and the surface markers (MHC-II, CD86 and CD40) of treated DC were detected by flow cytometry. CFSE-labeled PUVA SP were incubated with LEW DCs and the phagocytosis of DCs on PUVA-SP was observed by using fluorescent microscope. The ability of DC phagocytosing allogeneic PUVA-SP (PUVA-SP DC) to stimulate the proliferation of LEW T cells was analyzed by mixed leukocyte reactions (MLR). The production of IL-4, IL-10, IL-2, IFN-gamma in MLR culture supernatant was determined by luminex method. The results indicated that the PUVA treatment effectively induced early apoptosis of DA rat spleen lymphocytes. After co-culture, DC efficiently phagocytosed allogeneic PUVA-SP and still maintained an immature phenotype with low levels of MHC II, CD40 and CD86. PUVA-SP DC induced LEW T cell hyporesponsiveness to DA rat antigen, and led to skewing of T cell cytokine expression toward Th2 (IL-10 and IL-4). It is concluded that the PUVA-SP DC effectively down-regulate T cell response to alloantigen and induce Th2 immune deviation in vitro.

Abstract
Membrane grafting of methoxypoly(ethylene glycol) [mPEG] to allogeneic leukocytes attenuates allorecognition and significantly reduces the risk of graft-versus-host disease in mice. To optimize the immunological efficacy of polymer grafting, murine splenocytes were modified using three differing linker chemistries: CmPEG (5 kDa), BTCmPEG (5 and 20 kDa) and TmPEG (5 kDa). In vitro immunocamouflage efficacy was examined by flow cytometic analysis of leukocyte markers and mixed lymphocyte reactions (MLR). In contrast to CmPEG and BTCmPEG, TmPEG exerted significant cellular toxicity. Flow cytometric analysis demonstrated that both CmPEG and BTCmPEG were highly effective at camouflaging cell surface markers while TmPEG was ineffective. Furthermore, CmPEG and BTCmPEG dramatically blocked MLR allorecognition and cellular proliferation. Polymer length was the most critical factor in the immunocamouflage of cells with the BTCmPEG 20 kDa being the most effective. In contrast to other immunomodulatory approaches, immunocamouflage of leukocytes yields a multivalent effect globally interfering with attachment, allorecognition, presentation and costimulation pathways.

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
A previously unrecognized canine red cell antigen, tentatively named O, was found after absorption analysis of an alloimmune antiserum and absorption of several immune or naturally occurring cross-reacting heteroantibodies from man, cattle and swine. The serological results and genetic analysis of a limited number of complete dog families indicated that the new factor probably belongs to the Tr blood group system. No individual possessed both factors Tr and O, and a large proportion of animals was negative for both factors. The serological pattern for the new Tr system obtained was consistent with similar systems observed in sheep (A-O), pig (R-O) and man (Bombay) in which the gene for one factor was dominant over and masked the gene for the second factor in the system. The negative phenotype was accounted for by the actions of an epistatic gene.

Abstract
Serum samples from 134 Greek haemophiliacs multitransfused with fresh frozen plasma and factor--VIII or factor--IX concentrates were investigated for the presence of blood group antibodies. All samples were tested against a panel of selected cells of known but differing genotype. The incidence of blood group antibodies was 12.7%. Anti-D was found in 6 out of the 17 immunized patients, i.e., 35.3% of D-negative haemophiliacs were sensitized. It is concluded that the high incidence of immunization is a serious complication of repeated plasma transfusions.

Abstract
Patients with sickle cell disease (SCD) who receive red blood cell (RBC) transfusions have a higher rate of anti-RBC (allo and auto) antibody development than other transfused subjects. We hypothesized that an incidence and/or kinetics of RBC-specific antibody formation in SCD patients is influenced by a linked inheritance of the hemoglobin beta S (HbbetaS) allele and a polymorphism rs660C/T in the neighboring Ro52 gene. We found that 75% of C/T heterozygous and only 30.8% of T/T homozygous patients that developed antibodies were first transfused before the age of five. In addition, there was a significant inverse correlation between time of exposure to antigen or number of transfusions received and the age when T/T patients received first transfusion, indicating progressive development of competence of their immune system. In contrast, this correlation was not observed in patients with C/T genotype. Finally, increased expression of Ro52 was associated with the presence of the T/T genotype. These results suggest that rs660 polymorphism is a marker of efficiency of tolerance induction in early childhood and immune competence development to RBC antigens in SCD patients of pre-teen/teen age.
