Abstract
We report three Japanese children with chronic active Epstein-Barr virus (EBV) infection and neurologic findings that included symmetric calcifications in the bilateral basal ganglia. This finding, common in pediatric acquired immunodeficiency syndrome (AIDS), suggests that EBV could be responsible for calcification in the basal ganglia seen in children with AIDS and in other idiopathic diseases.

Abstract
UNLABELLED Severe combined immunodeficiency (SCID) with a normal number of B-lymphocytes usually demonstrates an X-linked inheritance and now is regarded as an interleukin-2-receptor (IL-2R) gamma-chain gene defect. Here, we report the characterization of mutations in the IL-2R gamma-chain gene of six unrelated SCID patients. One large deletion, one short deletion, one nonsense mutation and three single missense mutations were identified. The missense mutations were located near the motifs common to members of the class I cytokine receptor family. Two of the missense mutations were the same as previously reported in spite of the difference of ethnic backgrounds. The remaining four patients had newly identified mutations. CONCLUSION Our results emphasize the broad molecular heterogeneity of X-linked SCID and suggest the presence of mutational "hot spots" within the IL-2R gamma-chain gene.

Abstract
Deficiencies of Bruton's tyrosine kinase (Btk) have been implicated in the pathogenesis of human X-linked agammaglobulinemia (XLA). The distinctive phenotype observed in B-cell deficiency indicates the crucial role of Btk in B-cell development. This report describes a nationwide study of Btk deficiency in Japan, covering 51 XLA patients (35 independent families). Along with the identification of mutations, the resulting protein products were characterized by an in vitro kinase assay and a Western blot analysis. Thirty-one of the families were found to have mutations in the coding region of Btk. Although mutations were not found in the cDNA of 4 families, the Btk transcripts of these patients were greatly reduced. The identification of several novel missense mutations, in combination with the result of other studies, clarified the presence of two (missense) mutation hot spots, one in the SH1 and the other in the PH domain. The absence of kinase activity seen in 32 of the families underscored the importance of Btk protein analysis as a diagnostic indicator of XLA. The protein analysis also clarified the different effects of missense mutations on kinase activity and protein stability.

Abstract
We describe an experience of a specific immune transfer treatment in a patient with chronic active EBV infection. The patient had low anti-EBV T cell-mediated cytotoxic activity in his peripheral blood mononuclear cells (PBMC), which may have been the primary cause of the disease. An EBV-specific cytotoxic T lymphocyte (CTL) line was established from PBMC obtained from the patient's sister whose human leucocyte antigens (HLA) are identical to patient's. The patient received three courses of intravenously administered CTL at 3-week intervals. The number of the cells was increased with each course of treatment. After infusion of the T cell line, anti-EBV CTL activity was detected in the patient's PBMC. CTL activity increased markedly after the second course of immune transfer therapy. The amount of EBV DNA in the patient's plasma showed transient but repeated decreases. Serum levels of tumour necrosis factor-alpha (TNF-alpha), which had elevated before treatment, began to decrease after initiation of treatment. No adverse effects were directly associated with CTL infusions. Despite having previously received a pneumococcal vaccine and prophylactic antibiotics, the patient died of infection caused by Streptococcus pneumoniae bacteraemia 27 days after the third infusion. Although the long-term efficacy and safety of this therapy remains to be established, our findings suggest that adoptive transfer of CTL specific for EBV obtained from an HLA-matched donor might be a promising treatment for patients with chronic active EBV infection.

Abstract
Severe chronic active Epstein-Barr virus (EBV) infection is a lymphoproliferative disease characterized by extremely high antibody titers to EBV, fever, lymphadenopathy, hepatosplenomegaly, and pancytopenia, without any prior immunological abnormality. A spontaneous lymphoblastoid cell line was established from a 4-year-old boy with severe chronic active EBV infection. Immunofluorescence and Western blotting analyses showed that the cell line was of B cell origin and expressed Epstein-Barr nuclear antigens 1, 2 3a, 3b and 3c, and latent membrane protein 1, which are reported to be targets for EBV-specific cytotoxic T lymphocytes (CTL). The cytotoxicity of peripheral blood mononuclear cells derived from the patient and his HLA-identical sister was assayed against the cell line. The cell line was recognized and killed by anti-EBV CTL derived from the HLA-identical sister, but the patient's peripheral blood mononuclear cells had no cytotoxicity. We conclude that antigen presentation in the EBV-infected cells from the patient is intact and sufficient for generation of an EBV-specific CTL response. These observations suggest that severe chronic active EBV infection may not be caused by impaired EBV-antigen presentation of the infected cells but by impaired cellular immune responses to the virus. Our results also suggest the therapeutic possibility that this disease may be treated by adoptive transfer of EBV-specific CTL or bone marrow transplantation from an HLA-matched donor whose immune response to EBV is intact.

Abstract
An infant suffered from psoriasiform dermatitis complicated by severe constitutional symptoms. During his 12 months of hospitalization, the symptoms exacerbated periodically despite numerous therapeutic trials. Histologic findings revealed lichenoid psoriasiform dermatitis with striking eosinophilic necrosis of epidermal cells and satellite cell necrosis. Immunohistochemically, CD1+ Langerhans cells had almost disappeared, and CD8+ cytotoxic-suppressor T cells were predominant over CD4+ helper-inducer T cells in the epidermis. These findings in the skin biopsy specimens suggested some similarity to graft-versus-host disease but no known cause of that disorder was proved. Finally, methotrexate was effective. The patient became afebrile, and his skin lesions improved, leaving almost no scarring. This patient seems to have had specific clinical features that do not correspond with any of the known dermatitis. Clinical, histologic, and laboratory findings did not uncover any etiologic factors.

Abstract
We investigated the patterns of DNA rearrangements at loci for Ig JH genes in patients with severe combined immunodeficiency (SCID). Four SCID patients without B cells (B- SCID) and four SCID patients with B cells (B+ SCID) were examined. Bone marrow cells of these patients were transformed with EBV. The majority of the transformed cells from three B- SCID patients had the germline configuration at their JH gene loci. The rearranged fragments from one patient were analyzed extensively. The rearranged regions in all of the fragments had a common structure wherein two fragments derived from the JH-S mu region were connected inversely. The possible presence of rearranged forms of VHDJH and DHQ52JH sequences in bone marrow cells of two B- SCID patients were examined directly by the polymerase chain reaction (PCR) method. In one patient, we found neither a VHDJH sequence nor a DHQ52JH sequence within the range of sensitivity of the PCR method. In another patient, we found a VHDJH sequence at an extremely low level and DHQ52JH sequences at a relatively low level. Either RAG-1 or RAG-2 gene was not expressed in the B- SCID-derived cell lines. B+ SCID patients did not show any abnormalities in terms of VHDJH rearrangements. These results indicate that B- SCID may be caused by defects in factors involved in V(D)J rearrangements.

Abstract
The X chromosome inactivation analysis of eight female relatives was performed to elucidate the X chromosome gene defect of six male hypogammaglobulinaemic individuals. The patients had diminished numbers of circulating B-cells and no relevant family history. The methylation status of three X-linked genes, phosphoglycerate kinase, hypoxanthine phosphoribosyl transferase and DXS255, was determined on DNA from Epstein-Barr virus-transformed B-cell lines established from the female relatives. The methylation pattern of at least one gene was informative in all eight females examined. While both alleles were equally methylated in four of eight females, the remaining four female relatives of three hypogammaglobulinaemia patients exhibited a non-random methylation pattern in their B-cells, suggesting that these three patients represented sporadic cases of X-linked agammaglobulinaemia (XLA). The clinical or immunological status of these three patients did not differ from the remaining two who had early onset hypogammaglobulinaemia and who were tentatively diagnosed as having common variable immunodeficiency. The sixth patient had recurrent infections after undergoing surgical removal of a brain tumour at 22 years of age, although his immunological features did not distinguish him from the other patients. X chromosome inactivation analysis can be useful in differentiating XLA from hypogammaglobulinaemia in male patients.

Abstract
Concentrations of Tegafur, 5-FU, and Uracil were measured in the tissues and serum of 32 patients with malignant head and neck tumors after administration of UFT or UFT and OK-432. Of the 32 patients, 15 patients were treated with UFT alone and 17 patients with a combination of UFT and a clinical dose of OK-432. The level of 5-FU was higher in the tissues and serum in the patients who received the combined administration of UFT and OK-432 than in those the received UFT alone. In particular, levels of 5-FU in tumor tissue and metastatic lymph node tissue were higher than 0.05 micrograms/g even 14.6 hours after the last administration of UFT. No significant undesirable interactions between UFT and OK-432 were exhibited during combination therapy of these agents in clinically administered doses. From our satisfactory results, clinical cures would be expected by the combined immuno-chemotherapeutic action of these agents.

Abstract
In a previous study (Immunogenetics 1988. 27:330) with Epstein-Barr virus, we established lines of precursor B cells from bone marrow cells of a patient with severe combined immunodeficiency in whom the numbers of B cells and T cells were markedly reduced. Although based on their surface markers these cell lines appeared to be at an early stage of B cell differentiation, the gene loci for immunoglobulin heavy chains (IgH) retained the germ-line configuration on both chromosomes in almost all the transformants. In this study, we found that the enhancer sequence, located between the JH and mu genes, was hypomethylated and an abundance of the germ-line Cmu transcript was detected in these cell lines by Northern hybridization. These results suggest that the chromatin structure of the IgH gene locus in these cell lines is accessible to VDJ recombinase and is able to participate fully in DNA rearrangement. By contrast, we did not detect transcripts of the RAG-1 and RAG-2 genes, which are required for V(D)J recombination at gene loci for immunoglobulin and T cell receptors. Thus, it seems likely that these cell lines fail to initiate the V(D)J recombination process because of some deficiency in the formation of VDJ recombinase, which includes the inability to express RAG genes.

Abstract
The methylation pattern of three X-linked genes, phosphoglycerate kinase (PGK), hypoxanthine phosphoribosyl transferase (HPRT) and DXS255 detected by hypervariable M27 beta probe, was analysed to determine the proportion of aplastic anaemia (AA) with clonal haematopoiesis in Japanese children. Methylation analysis was performed on DNA from separated granulocytes and compared to that of bone marrow derived fibroblasts to exclude selective lyonization in all somatic cells. Of 20 female patients examined, the methylation pattern of at least one gene was informative in granulocyte DNA from 18 patients (90%). Of these, 8/20 patients (40%) were heterozygous for PGK, 8/18 (44%) were heterozygous for HPRT and 17/18 (94%) were heterozygous for DXS255. In 14/18 patients both alleles were equally methylated. Four patients exhibited a unilateral methylation pattern in their granulocytes. The same unilateral pattern was again demonstrated in fibroblasts from two of the four patients suggesting that in the latter one X chromosome was selectively inactivated in all of the somatic cells. The remaining two patients showed a unilateral methylation pattern that was restricted to their granulocytes, suggesting the existence of true clonal haematopoiesis. They responded well to antilymphocyte globulin (ALG) and presently have no evidence of a clonal disorder such as myelodysplastic syndrome (MDS) or paroxysmal nocturnal haemoglobinuria (PNH). Although these results indicate that some children with AA exhibit clonal haematopoiesis, analysis of a greater number of subjects will be required to establish the clinical value of clonal haematopoiesis in patients with AA.

Abstract
Therapy with antilymphocyte globulin (ALG) has been shown to be effective in restoring hematopoiesis to some patients with aplastic anemia. It would be useful to have a method for predicting those likely to be responders versus nonresponders. The mode of immunostimulatory action of ALG is of interest in addition to its immunosuppressive action. We examined in vitro the distribution of the proliferative responses of ALG-stimulated peripheral blood mononuclear cells (PBMCs) obtained from 18 patients with aplastic anemia, eight of whom responded to ALG and 10 who did not. We found a significant difference in the proliferative response of PBMCs obtained from the eight responders versus the 10 nonresponders (P less than .01). Two-color flow cytometry analysis of the patients' PBMCs stimulated by ALG in vitro showed that the CD4-positive subsets were activated to a greater extent by ALG than the CD8-positive subsets. Moreover, a positive correlation with the clinical response of patients to ALG with granulocyte-macrophage colony-stimulating factor produced by their PBMCs stimulated by ALG suggests that the immunostimulatory property of ALG has an important role in the treatment of aplastic anemia. Our results suggest that the clinical response to ALG therapy is correlated with its lymphocyte proliferative effect in vitro, and indicates that the assessment of the proliferative response of PBMCs in vitro would be useful in predicting the clinical response to ALG therapy.

Abstract
Twenty-one previously untreated cases, who underwent the same protocol at our department from January 1984 until December 1986, were investigated. The following results were obtained. Non-Hodgkin's lymphoma accounted for 10.5% of all the head and neck malignant tumors at our department. The age range was from 23 to 76 years of age and had a peak in the forties. Fourteen were male and seven were female. According to the stage distribution, six cases were stage I (28.6%), nine were stage II (42.9%), four were stage III (19.0%) and two were stage IV (9.5%). Stage I and II accounted for 71.4%. By site grouping, palatine tonsil and nasal cavity accounted for 38.1%, respectively. Surgical therapy was presumably useful for a solitary lesion which resisted all conservative therapies. By combined therapy with radiotherapy, VAPE-Chemotherapy and OK-432-immunotherapy, the survival rates were 100% (stage I), 77.8% (Stage II), 50% (stage III) and 50% (stage IV). The mean survival rate was 76.2%.

Abstract
In an attempt to characterize the genes that cause immunodeficiencies such as X-linked agammaglobulinemia (XLA) and severe combined immunodeficiency (SCID) we established precursor B-cell lines by transforming the patients' bone marrow cells with Epstein-Barr viruses. DNA rearrangements of immunoglobulin JH gene loci were observed on both chromosomes in pre-B cells derived from an XLA patient. We cloned and characterized both rearranged bands from one cell line. Both of the rearrangements occurred between DH and JH gene loci without the VH-DH structure. On the other hand, JH gene loci retained the germline configuration on both chromosomes in almost all the transformants derived from a SCID patient that had been determined according to their surface markers, to be in an early precursor B-cell stage. The implications of the observations are discussed.

Hybrid human-mouse T-cell clones reactive with Tp40 antibody, which detects cluster of differentiation (CD)7 antigen on human T lymphocytes, were established. Karyotype analysis showed that human chromosome 17 was essential for the expression of CD7 antigen. The presence of this chromosome was confirmed by enzyme analysis of galactokinase, which is coded by a gene on human chromosome 17.

Abstract
Peripheral blood mononuclear cells (PBMs) from 6 patients with ataxia-telangiectasia (AT) were studied by 5 kinds of cell-mediated cytotoxicity systems. Decrease in cell mediated lympholysis (CML) activity to allogeneic lymphocytes was observed in all 6 AT patients who had low numbers of OKT-3+ cells. These patients also showed decreased proliferative responses to phytohemagglutinin stimulation and allogeneic lymphocytes. In contrast, antibody-dependent cell-mediated cytotoxicity (ADCC) activity and natural killer (NK) activity were comparable with those in normal controls. In addition, PBMs from these AT patients activated by in vitro stimulation with allogeneic PBMs or interleukin-2 were able to acquire lytic activity against NK-insensitive target cells. The phenotypes of these effectors determined by complement-mediated lysis were OKT-3- and Leu-11+, suggesting that they were derived from NK cell lineage. Thus, AT patients with severe T cell defects were found to maintain a normal range of NK, ADCC, MLC-activated and lymphokine-activated killer activity.

Abstract
Ten patients with common variable immunodeficiency were classified into three groups according to the number of circulating B-cells, i.e. B-cells being absent (three patients), very low (three patients) or within the normal range (four patients). The four patients in the last group showed significant proliferative responses to the T-independent B-cell mitogen, formalin-fixed Staphylococcus aureus, Cowan I. Further study of these patients by co-cultures with allogeneic T or B-cells in various combinations with pokeweed mitogen showed that two patients had an intrinsic B-cell defect without T-cell defect. The third patient had a T-cell dysfunction (i.e. his T-cells could only help the B-cells of some individuals) resulting in a defect in Ig production. The T-cells of the fourth patient showed poor helper function towards all controls. All six patients with absent or very low numbers of B-cells in group I and II had normal T-cell helper function. This study demonstrates that the immunological defect in common variable immunodeficiency is most often a B-cell defect at different stages of their differentiation with sometimes an additional T-cell dysfunction.

Abstract
A pan T-cell antigen with a molecular weight of 120 kilodaltons (kd) is recognized by a monoclonal antibody, Tp120, produced in our laboratories. Two hybrid clones reactive with this Tp120 antibody were established from the fusion between concanavalin A-stimulated human peripheral blood lymphocytes and hypoxanthine-guanine phosphoribosyltransferase-deficient mouse T cell leukemia, BW5147. These two clones were also positive with two other antibodies, 12.1 and T12, both of which detect 120kd pan T-cell antigen. Karyotype analysis showed that one clone retained human chromosomes 6, 7pq-, and 11, and the other maintained chromosomes 11 and 21. As soon as both of these clones lost the chromosome 11, the expression of Tp120 became negative. The presence of human chromosome 11 was confirmed by the isozyme analysis of lactate dehydrogenase-A. The results indicated that the presence of chromosome 11 was essential for expression of 120kd pan T-cell antigen.

Abstract
Mouse monoclonal antibodies were produced against MT-2 cell line derived from adult T-cell leukemia or human T-cell leukemia virus-rich fraction therefrom. Two IgG1 antibodies, Ta60a and Ta60b, were found to be reactive not only with cell lines derived from adult T-cell leukemia or cutaneous T-cell lymphomas, but also with activated peripheral blood lymphocytes, suggesting the similarity of Ta60 antigen group to Tac antigen which is present on interleukin 2 receptor. Thus, the relationship among these antigens was studied. Two Ta60 antibodies and Tac antibody immunoprecipitated the molecule with almost identical electrophoretic mobility, approximately a Mr 60,000 antigen from [3H]glucosamine-labeled activated peripheral blood lymphocytes or MT-2, MT-1, or ATN-1 cells from adult T-cell leukemia and a Mr 53,000 antigen from HUT-102 cells derived from cutaneous T-cell lymphomas. Further, Tac antibody was found to immunoprecipitate Ta60b molecule on 125I-labeled MT-2 cells by sequential immunoprecipitation, indicating that these two epitopes are on the same molecule. Antibody binding inhibition assays with either 3H-labeled Ta60a or Ta60b antibody demonstrated that Ta60a and Tac are the same epitope, but different from Ta60b. Thus, at least two epitopes were demonstrated to be present on interleukin 2 receptor molecule. However, Ta60b antibody showed almost no blocking effects on proliferation of an interleukin-2-dependent cell line, whereas Ta60a antibody did. Various hematopoietic tumor cells were typed with these two antibodies, but the results with Ta60b antibody were described, because they showed a similar specificity. Ta60b antibody reacted with all adult T-cell leukemia cases, but did not react with T-cell acute lymphoblastic leukemia, lymphoblastic lymphoma, or mature T-cell lymphoma. Interestingly, 3 of 12 acute myeloblastic leukemia and 2 of 5 chronic myelocytic leukemia in blastic crisis showed positive reactions. One-third of B-cell chronic lymphocytic leukemia and B-cell lymphoma as well as a few B-cell lines were also weakly reactive with this antibody. A part of the results with direct tests was confirmed by the absorption tests. The results obtained demonstrated the presence of Ta60b on a certain fraction of malignant hematopoietic cells of other than T-cell origin.

Abstract
Five antigen systems were defined by the monoclonal antibodies (MoAb) produced against mature T cells. The antigens recognized were grouped into two categories based on the antigen distribution on T cells. (a) Tp 120 [mol. wt 120 kilodaltons (120kD)] and Tp40 (40kD), these are on most peripheral T cells, but not on any other cell lineages, i.e. pan-T antigen. (b) Ts32 (32kD), Ts145 (145kD) and TsA (not determined), these antigens are present only on certain populations of peripheral T cells, i.e., T subset antigen. Among these five, Ts145 and TsA are probably novel T cell antigens. Cell surface phenotypes of leukaemias and lymphomas were typed with these MoAb. Ia like antigen negative, null cell type acute lymphocytic leukaemia (Ia- null ALL) are Tp40+, suggesting that this type of ALL belongs to a T cell lineage. T cell ALL (T-ALL) and lymphoblastic lymphoma (LL) were both Tp40+, Ts32+, TsA+ and a half of the cases were Tp120+, but the expression of Tp40 was stronger on LL cells. Mature T cell (T2) lymphoma and adult T cell leukaemia (ATL) were Tp120+, TsA+, while Tp40 was weakly expressed on only one third of the cases. These MoAb were found to be useful to estimate the origin of various T cell malignancies.
