Abstract Abstract 1891 Background: The risk of acute GVHD after HSCT is increased in male recipients of female grafts. Disparities for the male-associated H-Y and other minor histocompatibility antigens (mHAs) have the capacity to sensitize alloreactive donor T cells and cause GVHD in HLA-matched recipients. These mHAs are polymorphic proteins that differ between donor and recipient and are presented as peptides by HLA molecules on recipient or donor antigen-presenting cells to donor immune cells. Currently, there is no evidence that minor histocompatibility antigen specific Tregs exist. Earli

Minor histocompatibility (mH) antigens appear to play a major role in bone marrow transplantation (BMT) using HLA-identical donors.

We have demonstrated that mH antigens can be recognized on hematopoietic progenitor cells, and residual recipient CTL specific for mH antigens expressed on donor hematopoietic progenitor cells may be responsible for graft rejection in spite of int

Minor histocompatibility antigens (MiHAs) are polymorphic peptides on the cell surface derived from self-proteins that are capable to induce an immune response during allogeneic hematopoietic stem cells transplantation. Their presentation occurs in the context of the certain major histocompatibility complex (HLA – human leucocyte antigen) alleles. One of the most common HLA alleles is HLA-A*02:01. Accordingly, for a significant number of donors and recipients pairs, it is possible to use the MiHAs presented in the HLA-A*02:01 as a target for relapsed leukemia therapy.

Abstract Inhibitory killer cell immunoglobulin receptors (KIR) bind to major histocompatibility complex antigens. Concise knowledge of KIR ligands allows prediction of natural killer (NK)–cell alloreactivity after hematopoietic stem cell transplantation. KIR3DL1 binds to the Bw4 epitope on HLA-B antigens. Although the same epitope is also found on 4 HLA-A antigens (HLA-A23/24/25/32), these are not currently regarded as KIR3DL1 ligands. We show that expression of HLA A*2301, A*2402, or A*3201 but not HLA A*2501 protects target cells from lysis by KIR3DL1+ NK cells. KIR3DL1+ NK cells from donors

The antigen system on the surface of human cells is responsible for recognizing foreign antigens. In organ transplantation, the immune system reacts to all foreign antigens that are different from the recipients antigens. In practice, solid organ transplantation is carried out with varying degrees of genetic discrepancy, while the main principle that should be followed to prevent acute and chronic transplant rejection reactions is to avoid unacceptable discrepancies. As a result, the diagnosis of typing genes of histocompatibility allows you to select a donor to which the recipient will not ha

A growing number of human tumor antigens have been described that can be recognized by cytotoxic T lymphocytes (CTLs) in a major histocompatibility complex (MHC) class I–restricted fashion. Serological screening of cDNA expression libraries, SEREX, has recently been shown to provide another route for defining immunogenic human tumor antigens. The detection of antibody responses against known CTL-defined tumor antigens, e.g., MAGE-1 and tyrosinase, raised the question whether antibody and CTL responses against a defined tumor antigen can occur simultaneously in a single patient.

It would be highly desirable that such responses include multiple T cell clones against multiple tumor antigens. This could be obtained using the antigen presenting capacity of dendritic cells (DCs) and cross-priming. That is, one could load the DC with tumor lines of any human histocompatibility leukocyte antigen (HLA) type to elicit T cell responses against the autologous tumor.

HLA antigen frequency and haplotype distribution are useful for determining disease associations, origin, migration and genetic relationships between populations and predicting the outcome of transplantation. Thus, the present study was carried outto identify HLA class I (HLA-A and HLA-B) antigen and haplotype distribution among a selected Bangladeshi population.

Abstract The glycoprotein E19, encoded in early region 3 of adenovirus-2, forms complexes with major histocompatibility complex class I antigens. As a result of the complex formation, the intracellular transport of the class I antigens is abrogated, and adenovirus-infected cells display gradually diminishing quantities of cell surface-expressed class I molecules. To assess whether the E19 protein interacts equally well with different class I antigens, the associations between the viral protein and HLA-A2 and HLA-B7 antigens have been estimated.

These donor T cells proliferate specifically in the presence of donor's peripheral blood monocytes (PBM) but not recipient's cells, and they kill specifically donor's but not recipient's Epstein-Barr virus (EBV)-induced lymphoblastoid cell lines (LCL).

The central role of histocompatibility leukocyte antigens (HLA) class II molecules in antigen presentation has received great attention in recent years, yet class I molecules have been defined as primarily functioning as a restriction element for cytotoxic T cell killing of virus-infected cells. Extensive clinical evidence, however, indicates that the HLA class I genes are strongly associated with nonseptic complications of enteric and genitourinary bacterial infections.

The transplant of organs is one of the greatest therapeutic achievements of the twentieth century. In organ transplantation, the adaptive immunity is considered the main response exerted to the transplanted tissue, since the principal target of the immune response is the MHC (major histocompatibility complex) molecules expressed on the surface of donor cells. However, we should not forget that the innate and adaptive immunities are closely interrelated and should be viewed as complementary and cooperating.

ABSTRACT Background and Objectives: Kidney transplants are effective for advanced renal failure, but graft rejection can occur when the recipient’s immune system misidentifies the kidney as a foreign object. Human leukocyte antigen (HLA), a component of the host’s immunological defense system, acts as a barrier to graft rejection. Selecting potential kidney recipients and donors for transplantation requires careful consideration of histocompatibility for the HLA-A, HLA-B, and HLA-DRB1 antigens. Mismatches between donors and recipients prolong transplant therapy, leading to lower graft survival

The classical class I human leukocyte antigens (HLA-A, -B, and -C) present allele-specific self- or pathogenic peptides originated by intracellular processing to CD8+immune effector cells. Even a single mismatch in the heavy chain (hc) of an HLA class I molecule can impact on the peptide binding profile. Since HLA class I molecules are highly polymorphic and most of their polymorphisms affect the peptide binding region (PBR), it becomes obvious that systematic HLA matching is crucial in determining the outcome of transplantation. The opposite holds true for the nonclassical HLA class I molecul

Antigen presentation by major histocompatibility complex class II molecules is essential for antibody production and T cell activation.

Abstract The paradigmatic model for the generation of peptide determinants for class II major histocompatibility complex molecules (MHC II) is that proteolytic fragmentation of antigen precedes the capture of the resulting peptides by MHC II (cut/trim first, bind later). However, circumstantial evidence exists to support an alternate model in which MHC II binding of antigenic epitope occurs prior to the proteolytic fragmentation of that antigen (bind first, cut/trim later). To distinguish between these two models, we analyzed the interaction of HLA-DR1 with two protein antigens, type II collag

Recipients of allogeneic bone marrow grafts run the risk of graft-versus-host disease (GvHD), even when the donor is an HLA-identical sibling. This may be caused by disparities in mHAgs between the donor and the recipient, with the antigen present in the recipient and not in the donor.
