A genomic cosmid library constructed from DNA from a genotyped individual (JF = HLA-A11, Cw–, B38/A26, Cw7, B51) was screened for clones containing class I histocompatibility genes. Among these clones, one was found to carry a 4.8 kb Hind III fragment which is highly correlated with HLA-A11. This clone was used to transfect LMTK+ cultured mouse fibroblast transformants expressing human beta-2 microglobulin. The human beta-2 microglobulin heavy chain-associated determinant was positively detected by the M18 monoclonal antibody. HLA-A11 expression on these doubly transformed cells was specifically demonstrated by complement-dependent cytotoxicity with HLA-A11 + A3-specific but not with HLA-A3-specific monoclonal antibodies. Absorption studies with human alloantisera confirmed the presence on these cells of HLA-A11 determinants and of cross-reacting determinants which absorbed anti-HLA-A1 and –A3 alloantisera. The JF5-J27 transfected cell expressed both heavy and light chains of human class I histocompatibility genes.Abbreviations used in this paper 2m

A major problem of allogeneic stem cell therapy is immunologically mediated graft rejection. HLA class I A, B, and Cw antigens are crucial factors, but little is known of their respective expression on stem cells and their progenies. We have recently shown that locus-specific expression (HLA-A, but not -B) is seen on some multipotent stem cells, and this raises the question how this is in other stem cells and how it changes during differentiation. In this study, we have used flow cytometry to investigate the cell surface expression of HLA-A and -B on human embryonic stem cells (hESC), human hematopoietic stem cells (hHSC), human mesenchymal stem cells (hMSC) and their fully-differentiated progenies such as lymphocytes, adipocytes and osteoblasts. hESC showed extremely low levels of HLA-A and no -B. In contrast, multipotent hMSC and hHSC generally expressed higher levels of HLA-A and clearly HLA-B though at lower levels. IFNγ induced HLA-A to very high levels on both hESC and hMSC and HLA-B on hMSC. Even on hESC, a low expression of HLA-B was achieved. Differentiation of hMSC to osteoblasts downregulated HLA-A expression (P = 0.017). Interestingly HLA class I on T lymphocytes differed between different compartments. Mature bone marrow CD4+ and CD8+ T cells expressed similar HLA-A and -B levels as hHSC, while in the peripheral blood they expressed significantly more HLA-B7 (P = 0.0007 and P = 0.004 for CD4+ and CD8+ T cells, respectively). Thus different HLA loci are differentially regulated during differentiation of stem cells. 相似文献

The specificity of the mouse class I-specific antibody COB6-3 was examined in detail. It was found to react with the mouse class I molecules H-2Db, Kd, and Qa-2, and with human HLA-A, –B, –C antigens. The specificity pattern of COB6-3, despite its different origin, was similar to that of the monomorphic HLA class I-specific antibody W6/32. Cross-inhibition studies show that on human cells the antigenic determinants recognized by the two antibodies are situated close together and may be identical. On mouse cells, reactivity of both antibodies was generated upon replacement of mouse beta-2 microglobulin (B2m) with its bovine counterpart, but differences in specificity were observed using human B2m.Abbreviations used in this paper B2m

T cells of two donors, JR (HLA-A23, 29; B7,7; G; DRw5) and HG (HLA-A2, 23; B40, w44; Cw4), were stimulated with cells from an HLA homozygous lymphoblastoid cell line JY (HLA-A2, 2; B7,7, C-, DRw4, 6) and cloned by limiting dilution after the third stimulation. Two cytotoxic T-cell (CTL) clones, JR-2-16 (from donor JR) and HG-31 (from donor HG), were used for detailed studies. The results of a panel study using lymphocytes from HLA-typed individuals and a study with two HLA recombinant families indicate that the antigens recognized by the CTL clones JR-2-16 and HG-31 were highly associated with HLA-A2 and HLA-B7, respectively. Blocking studies with a monoclonal antibody recognizing a framework determinant on HLA-A, -B and-C antigens and a monoclonal antibody reacting with HLA-A2 support the notion that JR-2-16 and HG-31 interact with the HLA-A2 and the HLA-B7 antigens per se. However, these clones did not recognize the HLA-A2 and HLA-B7 of all donors typed for these antigens, suggesting that the HLA-A2 and HLA-B7 antigens of these particular donors are variants of the serologically defined HLA antigens. These results indicate that in vitro-derived human CTL clones detect variations in the serologically defined allospecificities and can be used as reagents to elucidate the polymorphism of HLA antigens further.Abbreviations used in this paper: CTL

We have constructed cDNA clone libraries from two lymphoblastoid cell lines, JY (HLA-A2, B7, C untypeable) and LB (HLA-A28, B40, Cw3), and isolated clones encoding class I HLA antigens. We have characterized short oligonucleotide probes derived from the coding region of the HLA class I antigens which are specific for the HLA-A and -B loci. These probes have been used to subdivide the class I cDNA clones into subclasses. DNA sequencing of several HLA-A and -B related clones has allowed us to extend the primary structural characterization of these cell-surface antigens. This analysis has also detected a sequence polymorphism at the HLA-A locus, indicating that the previously considered homozygous typing cell line LB expresses two alleles of similar, although not identical, serological specificity. 相似文献

Cytotoxic T lymphocyte recognition of HLA-A/B antigens introduced into EL4 cells by cell-liposome fusion 总被引:1,自引:0,他引:1

HLA-A2 and -B7 antigens were introduced into EL4 (H-2b) cells by cell-liposome fusion and were used as targets or stimulators for cytotoxic T lymphocytes (CTL) generated in C57B1/6 (H-2b) mice. It was found that such EL4-HLA cells were not recognized by CTL that had been raised against either a human cell line bearing these HLA antigens or the purified HLA-A2 and -B7 antigens reconstituted into liposomes. In addition, EL4-HLA cells were not capable of inducing CTL that could recognize a human cell line bearing HLA-A2 and -B7 antigens. Instead, EL4-HLA cells induced CTL that specifically lysed EL4-HLA cells and not human cells expressing HLA-A2 and -B7. CTL recognition required the presence of HLA antigens on the EL4 cell surface and was inhibited by antibodies against either H-2b or HLA-A/B. Monoclonal antibody binding studies showed that the expected polymorphic determinants of the HLA-A2 and -B7 antigens were still present on EL4-HLA cells. However, the specificity of CTL or their precursors that are capable of recognizing HLA-A2 or -B7 was altered after these antigens became associated with the EL4 surface. Possible explanations for these results are discussed. 相似文献

Four human T lymphocyte clones exhibiting proliferative responses to class I HLA antigens were isolated from an in vitro mixed lymphocyte culture (MLC). Three clones expressed the Leu-2+3– phenotype and demonstrated proliferation in response to HLA-B8, while the fourth clone expressed the Leu-2–3+ phenotype and proliferated in response to HLA-A2. These clones were also cytotoxic towards cells bearing the same target antigens. Blocking studies utilizing monoclonal antibodies demonstrated that proliferation was triggered by determinants on the class I molecule itself, and these determinants appear to be spatially close to those which determine serologic allospecificity. These findings support the concept that the class I molecules themselves are the weak MLC stimulating determinants previously mapped to the HLA-A and B regions of the major histocompatibility complex.Abbreviations used in this paper B-LCL

Two types of biochemically defined class I major histocompatibility complex (MHC) antigens are found in the rat, RTLA antigens that are ubiquitously expressed and RTLC antigens which so far are detectable only on certain cell types, notably B and T lymphocytes. It is shown that the cytotoxic T lymphocyte response to minor H antigens of the LEW strain, including the H-Y antigen, and to TNP-modified syngeneic lymphoid cells is restricted by RTLA but not RTLC gene products. This conclusion is based on bulk culture assays including cold target inhibition tests and limiting dilution experiments using recombinants between the RT1
a and RT1
u haplotypes. The possibility that class I MHC antigens exist which have no major restriction function is discussed. 相似文献

Expression of the major histocompatibility antigens HLA-A2 and HLA-B7 by DNA-mediated gene transfer 总被引:3,自引:0,他引:3
C Bernabeu D Finlay M van de Rijn R T Maziarz P A Biro H Spits J de Vries C P Terhorst 《Journal of immunology (Baltimore, Md. : 1950)》1983,131(4):2032-2037
Genes coding for the heavy chain of the class I antigens HLA-A2 or HLA-B7 of the human major histocompatibility complex have been introduced into mouse LtK- cells by cotransfection with the herpes simplex virus thymidine kinase gene. HAT-resistant colonies were isolated expressing either HLA-A2 or HLA-B7 as monitored by indirect immunofluorescence. Immunoprecipitation analysis of both antigens by either sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) or isoelectric focusing (IEF) showed that they were identical to the HLA-A2 and HLA-B7 expressed in the human lymphoblastoid cell line JY (homozygous HLA-A2, HLA-B7). However, human cytotoxic T lymphocytes (CTL) generated against JY and CTL clones specific for HLA-A2 or HLA-B7 were unable to recognize the transfectants as targets. These results indicate that the human HLA-A2 (or B7) complexed with the murine beta 2-microglobulin could be an inappropriate target structure for the CTL. However, because the transfectants are not killed by human CTL even in the presence of lectins, it is suggested that other molecules that are not able to overcome the human-mouse species barrier may be involved in the killing mechanism. 相似文献

The cytotoxic effector cells that recognize HLA-D-region determinants and their precursors were characterized using monoclonal antibodies against human T lymphocytes and T-cell subsets. These studies were performed using MLC combinations giving rise to cytotoxic cells specific for both class I (HLA-A, B, C) and class 11 (HLA-D-region) antigens, and then tested against target cells displaying relevant antigens of only one class. Both class I and class II specific CTL (cytotoxic T lymphocytes) were inhibited by treatment with the OKT3 monoclonal antibody and complement, indicating that the effector cells were T lymphocytes. A major portion.of class II specific CTL, and their precursors, were inhibited by OKT4 and complement, while class I specific CTL from the same cultures were not. The T4+T8 — cell subset has previously been associated with helper or inducer functions, but not with cytotoxicity. The present findings indicate that class I and class 11 specific CTL, and their precursors, are different on the basis of the class of target antigen recognized and on the basis of surface phenotype detected by monoclonal antibodies. 相似文献

The human class I alleles HLA-A11 and HLA-A3 have a well-documented history of serological cross-reactivity. This cross-reactivity suggests that they are closely related, a suggestion which is supported by the fact that the HLA-A11 and HLA-A3 genes are distinguished from all other A-locus genes by a restriction fragment length polymorphism observed in Bam HI digests. To examine the extent of sequence homology between HLA-A11 and HLA-A3, we have cloned the HLA-A11 gene and sequenced the coding regions (exons). The results reveal that HLA-A11 and HLA-A3 display the highest degree of homology reported for any pair of serologically defined class I alleles. Only nine base differences resulting in six amino acid differences were observed in exons 2–8. One of the amino acid substitutions is in the 1 domain and the other five are in the 2 domain. Comparison of this sequence with that of other human class I molecules implicates Gln62 as a critical residue involved in HLA-A11 – HLA-A3 serological cross-reactivity. In addition, the amino acid sequence allowed us to successfully predict cross-reactive recognition of HLA-A11 by cytotoxic T lymphocytes specific for a rare subtype of HLA-A3, HLA-A3.2. This result provides further support for the importance of the 2 domain residues 152 and 156 in forming determinants on class I molecules that are recognized by cytotoxic T lymphocytes.Abbreviations used in this paper CTL

Long-term murine cytotoxic T-cell clones arising in response to stimulation with human lymphoblastoid cells and reactive with the HLA-A2 antigen are characterized. These clones distinguish between HLA-A2 and 21 other serologically defined HLA-A and -B antigens. In addition, most clones discriminate between prototypical HLA-A2 antigens, expressed by the majority of HLA-A2-positive individuals, and variant HLA-A2 antigens, which are serologically identical with the prototype, but distinguishable by human cytotoxic T cells and by biochemical analysis. This discrimination is reflected as an inability to cause any significant lysis of variant HLA-A2-expressing target cells at effector-to-target ratios 10- to 100-fold greater than those giving 50% lysis of prototype HLA-A2-expressing cells. By screening a panel of serologically HLA-A2-positive cells, a new variant HLA-A2-expressing cell line has been defined. The recognition patterns of these xenogeneic clones are suggested to reflect recognition of alloantigenic polymorphic determinants. Based on the strong bias in the xenogeneic T-cell repertoire for such determinants, we propose a model for T-cell recognition of class I products of the major histocompatibility complex. 相似文献

The role of major histocompatibility complex-encoded class I molecules in the proliferation of human B lymphocytes is presently unclear. This question was addressed by investigating the effect of three individually derived anti-HLA class I monoclonal antibodies (mAb) on purified human B cells (less than 1.5% T cells) stimulated by either the T-independent mitogen Staphylococcus aureus or the phorbol ester, phorbol-12-myristate-13-acetate. The three anti-HLA class I antibodies, whether specific for gene products of the HLA-A locus (mAb 131), HLA-B locus (mAb 4E), or HLA-A, -B, and -C locus (mAb W6/32), inhibited S. aureus-induced proliferation by 70 to 90%. This inhibition was significant over a 5-day culture period, was not altered by the addition of exogenous interleukin 2 or B cell growth factor, and was not due to nonspecific cytotoxicity. In addition, the inhibition of proliferation was unchanged when the mAb were added 12 hr after the initiation of culture. The proliferative response was not affected by either of the control antibodies OKB7 and R3-367. In contrast with S. aureus-stimulated B cells, phorbol-12-myristate-13-acetate-induced proliferation was resistant to the inhibitory activity of HLA class I-specific antibodies. These results suggest that HLA class I molecules are involved in human B lymphocyte proliferation and may regulate a critical event preceding the upregulation of protein kinase C activity. 相似文献

Comparison of one-dimensional IEF patterns for serologically detectable HLA-A and B allotypes 总被引:11,自引:0,他引:11

A new mouse monoclonal antibody (MoAb) 4E, which detects an epitope shared by HLA-B locus antigens, together with the MoAb W6/32, detecting a common HLA, B, C, determinant, and the MoAb 4B, detecting HLA-A2 and A28, were used to isolate HLA-A and -B antigens in sequential immunoprecipitation. The HLA antigens obtained from metabolically labeled cell extracts of B-lymphoblastoid cell lines or from phytohemagglutinin (PHA) activated peripheral blood lymphocytes were compared by one-dimensional isoelectric focusing (1D-IEF). The IEF banding patterns obtained with native HLA antigens segregated in a family with HLA. Neuraminidase treatment of isolated antigens reduced the number of bands to one or two, simplifying the analysis of characteristic patterns. Thus, we have cataloged IEF banding patterns for the majority of the serologically recognized HLA-A and -B allotypes obtained from 57 unrelated American Caucasians. While no HLA-A locus or HLA-B locus specific banding patterns were observed, the HLA-A antigens had, in general, slightly higher pl values than the HLA-B antigens. HLA-C antigens could not be detected in this assay system. The polymorphism detected by IEF banding patterns was as extensive as the serologically detected polymorphism identified by classical HLA serology. Moreover, variants for some HLA allotypes could be detected by this method. In addition to previously recognized A2 variants, new variants were identified for HLA-A1, A26, and Bw44. Each A1 and Bw44 variant was associated with particular haplotypes. The HLA-A2 antigens occurred on 43 HLA haplotypes in the unrelated Caucasian population. Only one of each A2 variants was identified in this population. 相似文献

The specificity of an antiserum directed againstI region associated (Ia) antigens is described. The serum was raised in (DBA/1×B10.D2)F1 mice against lymphocytes of AQR mice, differing from the responder for theI region only. The serum reacts with Ia antigens expressed on B cells (Iab) as well as with Ia antigens expressed on T cells (Iat). Absorption studies indicate that B cells possess at least two Ia antigens, and one of these is shared by T cells. However, this shared antigen is not present on the surface of lymphocytes of thymectomized mice. Analysis of the strain distribution of Iab and Iat antigens revealed that the Iab antigens are present on lymphocytes of mice carrying theIA
k
subregion and that the Iat antigens are present on lymphocytes of mice carryingI region genes of theH-2
k
haplotype located between theIA andIB subregions. This conclusion is based on the analysis of the antiserum's reactivity with T and B cells of the strains B10.A(2R), B10.A(4R) and B10.HTT: the serum reacts with B and T cells of B10.A(2R) but only with B cells of B10.A(4R) mice and only weakly with T cells of B10.HTT mice.Abbreviations ALG

Human serum was found to contain a variety of class I-like molecules by Western blotting with anti-class I heavy chain reagents: major bands usually are observed around M
r 44 000, 40 000, and 35 000–37 000. HLA-A24-positive individuals are distinguished by higher serum levels of M
r 44 000 and 40 000 class I-like molecules than those found in HLA-A24-negative individuals. The M
r 44 000 serum molecules are probably intact class I molecules that have been shed from the cell membrane, because they contain both a transmembrane segment (TM), as deduced from detergent-binding experiments, and a cytoplasmic tail (CT), as inferred from reactivity with an antipeptide serum specific for the cytoplasmic domain of class I antigens (RaCT). The M
r 35 000 and 37 000 molecules contain neither a TM nor a CT region and therefore are probably proteolytic breakdown products of cellular and/or serum M
r 44 000 molecules, although the existence of Q10-like molecules in man cannot be ruled out. The M
r 40 000 molecules do not contain a TM region. M
r 40 000 molecules reactive with the RaCT serum were found in the minority (2/13) of sera tested. We conclude that alternative splicing resulting in a precise excision of the TM exon plays a minor role in the generation of serum HLA class I antigens.Abbreviations used in this paper B2m

DNA of unrelated persons as well as members of families that were totally or partially homozygous or completely heterozygous on the loci of the major histocompatibility class I genes has been isolated from peripheral blood lymphocytes and blot hybridized with the class I pseudogene pHLA 12.4 probe. The autoradiographic DNA patterns were discussed and compared with well-defined serological features. Positive associations with serologically typed alleles had been demonstrated for HLA-A1,11 ; -A2; -A3; -B7; -B14; -B35;-Bw41; and -Cw5. 相似文献

We have previously reported that 90K/Mac-2 binding protein (M2BP) was highly expressed in lung cancer and that M2BP-specific immunity was observed in many of cancer patients. In this study, we analyzed the ability of 11 M2BP-derived oligopeptides with an HLA-A*0201-binding motif to induce M2BP-specific cytotoxic T lymphocytes (CTL) from peripheral blood lymphocytes of normal donors by in vitro stimulation. One of the CTLs that were induced using M2BP216-224 (RIDITLSSV) produced interferon-gamma in response to HLA-A2-positive T2 cells pulsed with the same peptide and lysed MDA-MB-231 cells expressing both M2BP and HLA-A2. The cytolytic activities were blocked by antibodies against HLA class I or CD8. These findings suggest that M2BP216-224 is naturally processed from the native M2BP in cancer cells and recognized by M2BP-specific CTLs in an HLA-A2 restriction. We first identified M2BP-derived CTL epitopes that may be useful as a target antigenic epitope in clinical immunotherapy of cancer. 相似文献

The polymorphism of feline MHC antigens was examined using biochemical methods. The following observations were made: (1) feline class I and II antigens are polymorphic. Their biochemical features were established using rabbit and mouse reagents directed against human MHC products; they resemble those observed for other mammalian species; (2) the expression of class II antigens in unstimulated cat peripheral blood lymphocytes (PBLs) appears to be unusually high. Cat PBLs express far more class II than class I antigens, whereas in human Epstein-Barr virus-transformed lines, which are known to express relatively large amounts of class II antigens, the situation is reversed.Abbreviations used in this paper EBV
