Full textIn the present work with mice, an experimental protocol was designed to verify whether or not a GVHR ensuing immunosuppression can occur even in the absence of a difference at the level of the major histocompatibility antigens.
Injection of lymphoid cells from donors histoincompatible with recipients at the level of one or multiple minor antigens induced a GVHR resulting in a marked decrease of humoral response of the recipients, and also a lack of ability of their lymphocytes to respond to mitogens.
This immunosuppression was associated with the presence of suppressor cells in the spleen of these animals. Furthermore histopathological studies demonstrated that the thymuses from animals experiencing a late GVHR induced across multiple minor histocompatibility antigens, showed signs of dysplasia.

Full textBackground. ABO and Rh(D) phenotyping of both blood donors and transfused patients is routinely performed by blood banks to ensure compatibility. These analyses are done by antibody-based agglutination assays. However, blood is not routinely tested for minor blood group antigens on a regular basis because of cost and time constraints. This can result in alloimmunization of the patient against one or more minor antigens and may complicate future transfusions. Study design and Methods. To address this problem, we have generated an assay on the GenomeLab SNPstream genotyping system (Beckman Coulter, Fullerton, CA) to simultaneously test polymorphisms linked to 22 different blood antigens using donor’s DNA isolated from minute amounts of white blood cells. Results. The results showed that both the error rate of the assay, as measured by the strand concordance rate, and the no-call rate were very low (0.1%). The concordance rate with the actual red blood cell and platelet serology data varied from 97 to 100%. Experimental or database errors as well as rare polymorphisms contributing to antigen conformation could explain the observed differences. However, these rates are well above requirements since phenotyping and cross-matching will always be performed prior to transfusion. Conclusion. Molecular profiling of blood donors for minor red blood cell and platelet antigens will give blood banks instant access to many different compatible donors through the set-up of a centralized data storage system.

Full textThe self/nonself discrimination system of vertebrates allows detection and rejection of pathogens and allogeneic cells. It requires the surveillance of short peptides presented by major histocompatibility class I (MHC I) molecules on the cell surface. MHC I molecules are heterodimers that consist of a heavy chain produced by MHC genes and a light chain encoded by the β2-microglobulin gene. The peptides presented by MHC I molecules are collectively referred to as the MHC I immunopeptidome. We employed systems biology approaches to define the composition and cellular origin of the self MHC I immunopeptidome presented by B lymphoblastoid cells derived from two pairs of MHC-identical siblings. We found that the MHC I immunopeptidome is subject- and cell-specific, derives preferentially from abundant transcripts, is enriched in transcripts bearing microRNA response elements and shows no bias toward invariant vs. polymorphic genomic sequences. We also developed a novel personalized approach combining mass-spectrometry, next-generation sequencing and bioinformatics for high-throughput identification of MHC I peptides including those caused by nonsynonymous single nucleotide polymorphisms (ns-SNPs), termed minor histocompatibility antigens (MiHAs), which are the targets of allo-immune responses. Comparison of the genomic landscape of the immunopeptidome of MHC-identical siblings revealed that 0.5% of ns-SNPs were represented in the immunopeptidome and that 0.3% of the MHC I-peptide repertoire would be immunogenic for one of the siblings. We discovered new factors that shape the self MHC I immunopeptidome and present a novel strategy for the identification of MHC I-associated peptides that could greatly accelerate the development of MiHA-targeted immunotherapy.
