Abstract
Human CMV still remains problematic in immunocompromised patients, particularly after solid organ transplantation. CMV primary disease and reactivation greatly increase the risks associated with incidences of chronic allograft rejection and decreased survival in transplant recipients. But whether this is due to direct viral effects, indirect viral effects including cross-reactive antiviral T cell immunopathology, or a combination of both remains undetermined. In this article, we report the novel TCR signature of cross-reactive HLA-A*02:01 (A2) CMV (NLVPMVATV [NLV])-specific CD8(+) T cells recognizing a specific array of HLA-B27 alleles using technical advancements that combine both IFN-γ secretion and multiplex nested RT-PCR for determining paired CDR3α/β sequences from a single cell. This study represents the first evidence, to our knowledge, of the same A2-restricted cross-reactive NLV-specific TCR-α/β signature (TRAV3TRAJ31_TRBV12-4TRBJ1-1) in two genetically distinct individuals. Longitudinal posttransplant monitoring of a lung transplant recipient (A2, CMV seropositive) who received a HLA-B27 bilateral lung allograft showed a dynamic expansion of the cross-reactive NLV-specific TCR repertoire before CMV reactivation. After resolution of the active viral infection, the frequency of cross-reactive NLV-specific CD8(+) T cells reduced to previremia levels, thereby demonstrating immune modulation of the T cell repertoire due to antigenic pressure. The dynamic changes in TCR repertoire, at a time when CMV reactivation was subclinical, illustrates that prospective monitoring in susceptible patients can reveal nuances in immune profiles that may be clinically relevant.

Abstract
Abstract
HLA-B*2705 is strongly associated with ankylosing spondylitis (AS) and reactive arthritis. In contrast, B*2709 has been reported to be more weakly or not associated to AS. These two molecules differ by a single amino acid change: aspartic acid in B*2705 or histidine in B*2709 at position 116. In this study, we analyzed the degree of T cell epitope sharing between the two subtypes. Ten allospecific T cell clones raised against B*2705, 10 clones raised against B*2703 but cross-reactive with B*2705, and 10 clones raised against B*2709 were examined for their capacity to lyse B*2705 and B*2709 target cells. The anti-B*2705 and anti-B*2703 CTL were peptide dependent as demonstrated by their failure to lyse TAP-deficient B*2705-T2 transfectant cells. Eight of the anti-B*2705 and five of the anti-B*2703 CTL clones lysed B*2709 targets. The degree of cross-reaction between B*2705 and B*2709 was donor dependent. In addition, the effect of the B*2709 mutation (D116H) on allorecognition was smaller than the effect of the other naturally occurring subtype change at this position, D116Y. These results demonstrate that B*2705 and B*2709 are the antigenically closest HLA-B27 subtypes. Because allospecific T cell recognition is peptide dependent, our results imply that the B*2705- and B*2709-bound peptide repertoires are largely overlapping. Thus, to the extent to which linkage of HLA-B27 with AS is related to the peptide-presenting properties of this molecule, our results would imply that peptides within a relatively small fraction of the HLA-B27-bound peptide repertoire influence susceptibility to this disease.

Abstract
The majority of patients with reactive arthritis have the major histocompatibility complex class I gene HLA-B27. The development of arthritis in these patients often occurs following infection with one of several enteric bacteria, including Yersinia enterocolitica. In this study, transgenic mice expressing HLA-B27 and their negative full sibs were infected intravenously with Yersinia enterocolitica 0:8 WA in an attempt to develop an experimental model of reactive arthritis. To date, no reactive arthritis has been observed; however, a significantly higher incidence of paralysis was observed in the HLA-B27+ transgenic mice. Injection of 10(5) organisms induced hind limb paralysis in 8 out of 30 of the HLA-B27 transgenic mice (27%) and in only 1 of the 24 negative siblings (4%). Paralysis occurred in 14 out of 30 HLA-B27+ mice (47%) at a dose of 10(4) organisms. Only 2 of the 25 negative siblings (8%) were affected at this dose. Paraspinal abscesses were found in all of the paralyzed animals. At the 10(4) dose most of the HLA-B27+ mice (70%) succumbed to the disease within 4 weeks, while the mortality in their B27- full sibs was less than 10%. Thus, HLA-B27 transgenic mice have higher mortality and morbidity from infection with Y. enterocolitica 0:8 WA than corresponding HLA-B27- littermates.

Abstract
A strategy, based on using V beta family-specific oligonucleotides, was developed for specific amplification and direct sequencing of human TCR V beta genes. With this strategy, it was possible to undertake a structural analysis of TCRs from human T cell clones in specific responses. 12 HLA-B27-specific cytotoxic clones were examined. The results reveal a nonrandom use of V beta gene diversity in this alloreactive response in that: (a) the clones express a restricted number of V beta segments, including a subset of V beta families that are significantly more related to one another than to most other V beta families; (b) five of seven clones having a particular reaction pattern with HLA-B27 subtypes possess Alanine at the D-J junction; and (c) identical J beta segments are found associated in several instances with identical or highly homologous V beta gene segments. In addition, two new V beta 13 members are reported.

Abstract
HLA-B2703, a mutation of HLA-B2705, is characterized by a Tyr-to-His substitution at position 59 in the alpha 1 domain of the class-I heavy chain. So far, the HLA-B2703 subtype was found only in two Black individuals and it is the first polymorphism at position 59 of MHC class-I molecules. We have examined whether the single amino-acid substitution at position 59 results in an alloantigenic determinant and HLA-restriction element, and whether HLA-B2703 functionally differs from HLA-B2705. In vitro, HLA-B2703-positive lymphocytes were not stimulated by HLA-B2705-positive cells. Nevertheless, HLA-B2703 was recognized as an alloantigen. HLA-B2702-anti-HLA-B2705 CTL lysed HLA-B2703-positive cells less efficiently than HLA-B2705-positive cells. In addition, anti-HLA-B27 antibodies were found that lysed HLA-B2705 but not HLA-B2703 positive cells. Also, CTL clones have been described that can distinguish HLA-B2703 from HLA-B2705 (1). However, the HLA-B2703 subtype did not function as a private virus restriction element. HLA-B2705-restricted influenza virus-specific CTL also recognized HLA-B2703-positive virus-infected cells, and vice versa. Thus, the HLA-B2703 mutation represents an example of a class-I antigen without specific significance for the recognition of viral peptides.

Abstract
HLA-B27 is strongly associated with susceptibility to ankylosing spondylitis and other spondyloarthropathies. Structural analysis of this antigen has revealed the existence of multiple variants, or subtypes, in human populations. The structural microheterogeneity of these subtypes deeply affects allospecific T cell recognition and most of it occurs at an spatial cluster within the peptide binding groove of the molecule. Many polymorphic residues whose combination is unique to HLA-B27 but is conserved among subtypes are clustered in a spatially separated site of the groove from that where most subtype polymorphism occurs. Site-directed mutagenesis and DNA-mediated gene transfer has been used to show that the positions that are polymorphic among subtypes are highly relevant for modulating T cell recognition, so that immunologically silent changes do not occur. These studies have also revealed an extremely high clonotypic diversity in the alloreactive response against HLA-B27. The structural basis for this diversity has been examined by sequencing the clonotypic T cell receptors. The analysis shows a certain bias in V beta gene segment usage, as well as other recurrent structural motives, among T cell receptor beta chains from HLA-B27-specific cytotoxic T cell clones.

Abstract
Beyond the resolution of tissue typing serology, HLA class I antigens display a certain level of structural microheterogeneity, that allows their subdivision into subtypes. The structure of these subtypes shows that multiple mechanisms operate in the generation of HLA polymorphism and suggests possible evolutionary pathways for subtype diversification. In addition, subtype polymorphism critically affects cellular allorecognition and antigen presentation to self-restricted T cells. These properties are used to define the structure and diversity of T-cell epitopes. In this review, José López de Castro discusses the nature and evolution of this polymorphism and its modulation of antigen recognition by cytolytic T lymphocytes.
