Abstract
Systemic sclerosis (SSc) is a multisystem disease characterized by T-cell infiltration of involved tissues, fibrosis, and small vessel vasculopathy. Using flow cytometric analyses, we found an increased percentage of gamma/delta T-cells expressing the T-cell antigen receptor variable (V) delta 1 gene segment in the peripheral blood and bronchoalveolar lavage fluid of patients with SSc. To estimate clonality of these V delta 1+ T-cells, the diversity of V delta 1 junctional regions (V-Diversity-Joining gene segments) was examined using a reverse transcriptase-polymerase chain reaction to amplify T-cell antigen receptor delta chain transcripts isolated from peripheral blood mononuclear cells, lung, esophagus, stomach, or skin of patients and controls. Limited diversity of V delta 1-J delta junctional regions in SSc patients was demonstrated by the finding of greater restriction in the nucleotide lengths of junctional region cDNAs in individual SSc patients than in controls. Sequence analyses confirmed that V delta 1-J delta junctional regions from the blood of SSc patients had less diversity than those from controls, in that a significantly higher proportion of sequences were repeated in patients (54.4% vs. 19.4% in controls). Evidence for selection of the V delta 1+ T-cells in tissues of individual SSc patients came from the findings that the same V delta 1-J delta junctional sequences could be isolated from the same tissue over time and that identical V delta 1-J delta junctional sequences could be isolated from multiple tissues. These data suggest that expansion of V delta 1+ gamma/delta T cells may be antigen driven in SSc patients.

Abstract
T cells which recognize antigen in association with self major histocompatibility complex (MHC) molecules are positively selected within the thymus. This results in skewing of the T-cell repertoire toward the recognition of antigenic peptides presented by self MHC molecules. While the thymus gland involutes at a relatively young age, bone marrow function and the size of the peripheral T-cell pool are maintained with age. We have investigated the MHC restriction of helper T-cell function for B-cell production of specific antibody in mice of different ages. Splenic helper T cells from 2- to 3-month old mice immunized with phosphocholine-keyhole limpet hemocyanin conjugate were MHC-restricted as defined by their capacity to induce phosphocholine-specific antibody synthesis by syngeneic but not by allogeneic B cells. In contrast, splenic T cells from immunized 18- to 20-month-old mice induced specific anti-phosphocholine antibodies by both syngeneic and allogeneic B cells. No evidence of polyclonal immunoglobulin synthesis was detected. The ability of T cells from old mice immunized with phosphocholine-keyhole limpet hemocyanin to induce phosphocholine-specific antibody synthesis by B cells from allogeneic mice was inhibited by T cells from immunized young mice. These findings suggest that non-MHC-restricted T-cell helper activity in old mice results from the loss of T cells, present in young mice, which suppress non-MHC-restricted helper cells.

Abstract
Human gamma delta T cell clones having V gamma 9JP and V delta 2DJ1 T cell receptor (TCR) gene rearrangements were isolated form an individual donor and tested for non-MHC restricted cytotoxicity against the B lymphoblastoid cell line, BSM. Most clones were highly cytotoxic but 3/9 clones had very low activity, comparable to that of CD4+ alpha beta T cell clones. Although there was a tendency for clones with low cytotoxic function to produce high levels of interferon-gamma and tumor necrosis factor-alpha, this correlation was not complete. TCR gamma and delta junctional sequences were obtained and were found to be different for all clones. There were no consistent structural differences between gamma delta TCRs of cytotoxic and non-cytotoxic clones, but gamma or delta junctional regions of all three non-cytotoxic clones had unusual features. One clone had a particularly short gamma chain junctional sequence, one had a short delta chain junctional sequence and the third clone was the only one of the panel which failed to utilise the D delta 3 segment. If the gamma delta TCR is involved in target cell recognition in this model of non-MHC restricted killing, such variations in receptor structure may be sufficient to inhibit recognition and thereby reduce the cytotoxic capacity of a minority of V gamma 9+/V delta 2+ clones. Also, a panel of gamma delta T cell clones expressing V gamma 8/V delta 3 isolated from a different donor, were all highly cytotoxic against BSM, indicating that these target cells can be recognised by effector cells expressing a TCR other than the V gamma 9/V delta 2 receptor. The possible influence of other cell surface molecules on non-MHC restricted cytotoxic function is discussed.

Abstract
gamma delta T cells are capable of mediating non-major histocompatibility complex (MHC) restricted lysis of a variety of tumour cell lines. The mechanism of this lysis and its significance in tumour immunity are not clear. We have used a panel of five malignant mesothelioma (MM) cell lines, as well as standard tumour targets K562 and Daudi, to investigate some of the factors which could be involved in non-MHC restricted cytotoxicity mediated by gamma delta T cells. Individual MM cell lines, representing a panel of lines derived from a single cell type, varied in their susceptibility to lysis by gamma delta T cell clones. Individual gamma delta T cell clones also showed unique cytotoxic profiles, and differed in their cytotoxic potential. T cell receptor (TCR) V gamma gene usage correlated with the ability of clones to lyse Daudi or K562; clones lysing Daudi expressing V gamma 9 and clones lysing K562 expressing V gamma I subgroup genes. No strict correlation between V gamma and V delta gene usage and MM reactivity was, however, demonstrable. There was also no correlation between gamma delta T cell lysis of MM cell lines and the capacity of gamma delta T cells to produce interferon-gamma, tumour necrosis factor-alpha, interleukin-2 or interleukin-4, nor with their expression of CD8.

Abstract
T cell lines have been derived from human kidney allograft biopsies using mitogenic stimulation. Southern blotting using a T-cell receptor (TCR) Cbeta probe revealed an oligoclonal pattern of rearranged bands in all 12 samples analysed. In some cases, differences in band patterns were noted between independent cultures from the same biopsy. Most T-cell clones derived from 2 biopsies showed different patterns of rearranged bands. The polymerase chain reaction (PCR) was used to study TCR Vbeta gene usage in allograft-derived T-cell cultures. This was more sensitive and more informative than Southern blotting and revealed that most TCR Vbeta genes were expressed in T cells from biopsies showing cellular rejection. The potential usefulness of this technique to quantify TCR V gene usage in allospecific T-cell populations is discussed.

Abstract
T-cell receptor gamma and delta gene expression was determined using V-region-specific monoclonal antibodies in conjunction with Southern blot analysis in panels of gamma delta T-cell clones from human peripheral blood (n = 77) and reproductive tissue (n = 9). Whereas 53 out of 77 (69%) clones from peripheral blood expressed V gamma 9 and V delta 2J1, only 2 out of 9 (22%) from reproductive tissues expressed V delta 2J1. Two out of eight decidual clones expressed both V gamma 9 and V delta 1J1, while this configuration was rare in clones from peripheral blood. The majority of clones from the peripheral blood of one donor expressed V gamma 8 and V delta 3J1. Clones were identified which expressed V delta 1J1 in the disulphide-linked C gamma 1 form of the receptor and which expressed a gene other than V delta 1 in the non-disulphide-linked C gamma 2 form, indicating incomplete concordance between expression of V delta 1 and C gamma 2. V delta 3 could be expressed in the disulphide-linked or non-disulphide-linked form of the receptor. At least 5 out of 77 peripheral clones were expressing V delta genes other than V delta 1, V delta 2, or V delta 3 in conjunction with C gamma 1 or C gamma 2. There was a strong but incomplete correlation between high non-NHC-restricted cytotoxic function and C gamma 1 expression. Clones from the same donor expressing both V gamma 9JPC gamma 1 and V delta 2J1 showed either high or negligible cytotoxicity, and cytotoxic clones expressing C gamma 2 were found. Thus no complete correlation between cytotoxic function and expression of a particular form of the gamma delta heterodimer was identified. The results also suggest that gamma delta T cells from reproductive tissues are less likely to express V delta 2J1 than those from peripheral blood.

Abstract
Peripheral blood mononuclear cells were enriched for gamma delta T cells by immunomagnetic separation, stimulated with cells from an allogeneic donor, and cloned. T-lymphocyte clones (TLC) of the two major gamma delta T-cell subsets, BB3+ (i.e. V delta 2+) and delta TCS1+ (i.e. V delta 1/(D)/J delta 1), were obtained. In addition, one gamma delta TLC was BB3- delta TCS1-. All of the BB3+ TLC showed strong cytotoxicity against various allogeneic tumor cell lines, such as Daudi and K562. The cytotoxicity against the tumour cell lines was modulated by MoAb against the gamma delta TcR. The BB3+ TLC were not cytotoxic against B-lymphoblastoid cell lines (B-LCL). In contrast, the delta TCS1+ TLC showed much lower cytotoxic activity against the tumour cell lines, but many were strongly cytotoxic against allogeneic B-LCL. Some of the delta TCS1+ TLC demonstrated HLA-specific cytotoxicity, while other delta TCS1+ TLC had a more broad cytolytic activity against B-LCL. Thus, the two major subtypes of gamma delta T cells from this donor, as defined by MoAb BB3 and delta TCS1, were distinct with respect to recognition specificity.

Abstract
T cell receptor (TCR) gamma gene rearrangements were examined in panels of human T cell clones expressing TCR alpha/beta or gamma/delta heterodimers. Over half of the alpha/beta+ clones had both chromosomes rearranged to C gamma 2 but this was the case for only 20% of the gamma/delta+ clones. While more than half of the gamma/delta+ clones showed a V9JP rearrangement, this configuration was absent from all 49 alpha/beta+ clones analysed. However, this was not a result of all rearrangements being to the more 3' J gamma genes as 11 alpha/beta+ clones had rearrangement(s) to JP1, the most 5' J gamma gene segment. Both alpha/beta+ and gamma/delta+ clones showed a similar pattern of V gamma gene usage in rearrangements to J gamma 1 or J gamma 2 with a lower proportion of the more 3' genes being rearranged to J gamma 2 than for the more 5' genes. Several alpha/beta+ and several gamma/delta+ clones had noncoordinate patterns of rearrangement involving both C gamma 1 and C gamma 2. Eleven out of fourteen CD8+ clones tested had both chromosomes rearranged to C gamma 2 whereas all clones derived from CD4-8- cells and having unconventional phenotypes (CD4-8- or CD4+8+) had at least one C gamma 1 rearrangement. Twelve out of twenty-seven CD4+ clones also had this pattern, suggesting that CD4-8+ clones had a tendency to utilize more 3' J gamma gene segments than CD4+ clones. There was some evidence for interdonor variation in the proportions of TCR gamma rearrangements to C gamma 1 or C gamma 2 in alpha/beta+ clones as well as gamma/delta+ clones. The results illustrate the unique nature of the V9JP rearrangement in gamma/delta+ clones and the possible use of a sequential mechanism of TCR gamma gene rearrangements during T cell differentiation is discussed.

Abstract
Clones were derived from highly purified human CD4-8- lymphocytes from three different donors and maintained in the presence of interleukin 2 and phytohaemagglutinin. Considerable variation was noted between donors in the phenotype and T-cell receptor (TCR) gamma gene rearrangements of CD4-8- -derived clones. In one donor, most clones remained CD4-8- and all were CD3+WT31- and therefore expressed gamma/delta heterodimers. TCR gamma gene rearrangements almost all involved C gamma 1. In contrast, most clones from a second donor were CD3+WT31+, and therefore expressed alpha/beta heterodimers, and many were positive for CD4 or CD8. Most clones from a third donor were CD3+WT31- with a high proportion of TCR gamma gene rearrangements involving C gamma 2. The V gamma 9JP rearrangement was exclusively confined to CD3+WT31- clones and was present in the majority of clones. Almost all CD3+WT31- clones showed TCR beta as well as gamma gene rearrangements. Most CD3+WT31- clones with at least one chromosome rearranged to C gamma 1 exhibited high non-major histocompatibility complex (MHC)-restricted cytotoxic activity, while most of those with two C gamma 2 rearrangements, and therefore expressing a non-disulphide-linked gamma/delta heterodimer, had low activity. Preincubation of effector cells with anti-CD3 strongly inhibited the cytotoxicity of CD3+WT31- clones while that of CD3+WT31+ clones was enhanced. This implicates the CD3-gamma/delta complex in target cell recognition by cytotoxic gamma/delta-bearing T-cell clones. The results show that there is heterogeneity between donors in the relative proportions of CD4-8- -derived clones expressing alpha/beta heterodimers and the different forms of the gamma/delta heterodimer.
