Abstract
Most nodal peripheral T-cell lymphomas (PTCL) originate from alphabeta-T cells, and they often contain reactive T cells that may hamper immunophenotyping. To specifically identify the neoplastic population in immunohistochemically stained slides, we assessed the heterogeneity of the T-cell receptor beta chain variable region (TCRVbeta). This region contains 65 gene segments, of which only one is expressed after rearrangement. To investigate PTCL, we developed a polymerase chain reaction assay to define the clonally rearranged TCRVbeta segment. Detecting the corresponding epitope with segment-specific antibodies enabled identification of tumor cells among the T cells. The TCRVbeta segment of the tumor cells was defined in 13 of 13 PTCL not otherwise specified and 11 of 13 angioimmunoblastic T-cell lymphomas. Antibodies corresponding to the respective TCRVbeta segment of the tumor were available for seven cases from each group. After applying these antibodies in combination with antibodies against CD3, CD5, CD4, CD8, and cytotoxic molecules, double stains were evaluated by confocal laser scanning microscopy. In 9 of 14 cases, less than 50% of T cells expressed the clonally rearranged TCRVbeta segment. Phenotypes defined in double stains differed from those obtained by conventional immunohistochemistry in 11 of 14 cases. The combination of TCRVbeta polymerase chain reaction and immunohistochemistry may facilitate more reliable detection and characterization of tumor cells in PTCL.

Abstract
The aim of this study was to evaluate the T-cell receptor (TCR) Vbeta repertoire in the two main histological subtypes of nodal non-anaplastic peripheral T-cell lymphoma: Not Otherwise Specified (NOS) and angioimmunoblastic lymphoma (AIL). Frozen lymph node tissues of eight NOS and six AIL were analyzed. A reverse transcriptase polymerase chain reaction (RT-PCR) was carried out to assess the expression of the 24 Vbeta gene families. Our study showed a broad TCR Vbeta repertoire in AIL and NOS, with a slight increase in the number of Vbeta families in AIL (16 vs 10 on agarose gels). Nevertheless, there was a clear difference in four cases. A predominant Vbeta family was observed in two NOS, whereas no predominant Vbeta family was observed in the AIL. Two AIL showed the whole Vbeta repertoire, whereas it was never observed in NOS. This pattern may help to categorize these histopathological entities and further suggests a differential T-cell response. These results show that numerous reactive T-cells are present both in AIL and NOS. Possibly, they play a role in the growth of these lymphomas.

Abstract
The identification of clonal rearrangements of T cell receptor (TCR) genes is central to the diagnosis of T cell lymphomas. However, in angioimmunoblastic lymphadenopathy (AILD), first described as a nonneoplastic proliferation associated with immunodeficiency, the heterogeneity of TCR and IgH gene rearrangements suggest that some cases may harbor multiple lymphoid clones. In this study we have isolated DNA from archival paraffin biopsy material from 22 cases of AILD identified on the basis of classical histological and immunohistochemical features with the aim of establishing the occurrence of clones and oligoclones, the frequency of TCR and immunoglobulin heavy chain (IgH) variable (v) gene use, and the relationship of these findings to the presence of Epstein-Barr virus. DNA extracted from the biopsies was amplified using the polymerase chain reaction (PCR) and sequenced to detect functional and nonfunctional gene rearrangements. Epstein-Barr virus-encoded short RNA species (EBERs) were detected using in situ hybridization combined with immunochemistry to identify the phenotype of the Epstein-Barr virus-infected cells. Fifty-seven clonal products were found in 20/22 patients: TCRgamma clonal products were identified in 16/22, TCRbeta clonal products in 16/22 and IgH clonal products in 6/22 cases. Oligoclonal PCR products were seen for TCR in 3/22 and for IgH in 3/22 cases. In one biopsy PCR products from all reactions were polyclonal. Sequence analysis revealed functional TCRgamma, TCRbeta, and IgH sequences in 6/12, 9/11, and 8/8 cases, respectively. Functional TCR and/or IgH oligoclones were detected in 6/20 (30%) cases. In addition, nonfunctional TCR and IgH sequences were found in 11 cases. EBERs were identified in 18/20 cases varying from occasional to 25 to 30% nuclei staining and were associated with both T and B cells, although the majority were of indeterminate phenotype. The presence of EBERs was not associated with all clonal IgH gene rearrangements but was associated with B cell oligoclones. Patterns of gene recombinations indicated that the majority of TCRgamma recombinations used GV1 and GJ1S3/2S3 genes. Six out of eleven cases used TCR BV4S1 or BV2S1 genes associated with various BJ and BD1/2 genes. No common IgH gene usage was identified, but 8 clones had varying degrees of replacement and silent mutations (0.6-10.1%), consistent with B cell clones having undergone somatic mutation in the germinal center, and 3 clones harbored unmutated V genes, consistent with naive B cells. Our data do not support the concept of AILD as a clearly defined peripheral T cell lymphoma (PTCL). Rather, they suggest that AILD as defined by histology and immunohistochemistry is either a heterogeneous entity or represents a lymphoproliferation associated with immunodeficiency in which clonal T cell or B cell proliferation may occur.

Abstract
AIMS Immunohistological and molecular characterisation of a case of peripheral T-cell lymphoma (PTCL) of angioimmunoblastic T-cell lymphoma (AILD) type. METHODS Frozen and paraffin wax sections of the diagnostic lymph node were stained with a panel of T- and B-cell lineage monoclonal antibodies. DNA was isolated from the paraffin wax embedded biopsy material for T-cell receptor (TCR) and immunoglobulin (Ig) PCR amplification, and resultant PCR products were cloned and sequenced. RESULTS Immunohistological analysis of the presenting lymph node was consistent with an extensive infiltrate of pleomorphic CD3+CD8+ lymphocytes. Most (>80%) of these infiltrating CD3+ cells were also positive for the TCR VB5.1 gene family product, and were shown to be oligoclonal by TCRB PCR amplification and sequencing. Three oligoclones of B cells were also demonstrable by PCR amplification with Ig heavy chain primers and sequencing, a finding at variance with the diagnosis of AILD. CONCLUSIONS These data demonstrate the complexity and heterogeneity of PTCL which require extensive histological examination and molecular characterisation.

Abstract
Cutaneous T-cell lymphoma (CTCL) is a malignancy of mature T lymphocytes, most of which express alpha/beta type T-cell receptors (TCRs). The cause of CTCL is unknown, but hypotheses postulating chronic stimulation of TCRs by superantigen or by a leukemogenic virus have been proposed. Either mechanism might produce bias in the TCR variable (V) region types used by the malignant cells. To determine if TCR alpha use is restricted in CTCL, we used reverse transcription and the polymerase chain reaction to determine V alpha and V beta usage by malignant cells purified from the peripheral blood of leukemic patients with CTCL. Usage of alpha chain V region segments appeared totally random; malignant lymphocytes isolated from each of six patients used different V alpha regions. As has been previously reported, no bias was found in beta chain V region usage either. In addition to productive (in frame) TCR V region mRNAs in malignant cells from each patient, we detected non-productive (out of frame) beta chain transcripts in these cells in two of six patients, and non-productive alpha chain transcripts in five of six. Residual normal peripheral blood lymphocytes from these patients showed a random, polyclonal or oligoclonal pattern of V region usage. We conclude that there is no bias in V region usage in CTCL, making it unlikely that interactions between superantigen or virus and the TCR V regions play a role in the pathogenesis of CTCL.

Abstract
In situ hybridization techniques using a cocktail of digoxigenin-labelled T-cell receptor (TcR) constant (C) region beta oligonucleotide probes were used to detect TcR beta mRNA in frozen and paraffin-embedded tissue sections. The specificity of the C beta cocktail was confirmed by Northern blot analysis. The TcR C beta cocktail successfully hybridized to T cells in frozen and paraffin-embedded tissue obtained from patients with inflammatory arthropathies, B- and T-cell non-Hodgkin's lymphoma (NHL), and reactive tonsillitis, and showed staining patterns comparable to those obtained by conventional immunohistological detection of T cells. This is the first report of in situ studies using labelled TcR C beta oligonucleotide probes and may indicate the feasibility of investigating clonal T-cell populations using digoxigenin-labelled clonospecific probes in clinical samples in situ.

Abstract
In the present study we report a serial investigation of the numbers of the peripheral blood cells--erythrocytes, polymorphonuclear neutrophils, total lymphocytes, T-lymphocyte subpopulations (CD2, CD4, CD8), B lymphocytes and monocytes--in a group of 21 patients with haemochromatosis during the time of intensive phlebotomy treatment, i.e., from iron overload until the onset of iron deficiency. A remarkable individual stability of all blood cell populations studied was found in all patients. Patients differed in their relative proportions of CD4+ and CD8+. Each individual's CD4/CD8 ratio, as well as the absolute numbers, remained unaffected with time, confirming the existence of a strict homeostatic regulation of the relative numbers of the two major peripheral T lymphocytes. A significant positive correlation between CD4/CD8 ratios and the amount of iron mobilised by phlebotomy was found during this study. A novel correlation between the relative proportions of CD4+ and CD8+ cells and iron overload is confirmed by the follow-up of iron re-entry in the serum transferrin pool in the treated patients.

Abstract
T-cell response against tumour-associated antigens is mediated by the TCR complex. To determine a possibly restricted TCR-V beta repertoire in reactive T-lymphocytes in Hodgkin's disease (HD), 20 cases (of which 10 were EBV-positive cases) were investigated using 14 monoclonal antibodies (MoAbs) recognizing 11 different TCR-V beta region family products and Northern blot analysis with cDNA probes specific for mRNA transcripts of 11 V beta families that were not detectable by MoAbs. Four V beta families (V beta 5, V beta 6, V beta 8, V beta 19) were investigated using both immunohistochemistry (IHC) with anti-V beta MoAbs and Northern blot analysis. Immunohistochemical and Northern blot findings were correlated with the detection of the Epstein-Barr virus (EBV) genome in Hodgkin's and Reed-Sternberg cells (H-RS). The non-neoplastic lymphocytes in HD were predominantly of T-phenotype (CD3+). Most of these cells were TCR-alpha beta+ (beta F1+) and only a few T-cells were reactive for TCR-delta 1 antibody (TCR-gamma delta+). In the majority of cases helper/inducer T-cells (CD4+) outnumbered suppressor/cytotoxic T-cells (CD8+). Labelling of these samples with the panel of 14 anti-V beta MoAbs showed that only a small percentage (0.2-5.5%) of beta F1+ lymphocytes were positive with each of these MoAbs. The proportion of these cells was comparable to that seen in normal tissues. Most TCR V beta+ cells were randomly distributed, but in virtually all cases occasional V beta+ cells pertaining to the various V beta families were seen in close contact to H-RS cells. Using total RNA extracted from malignant and normal tissues, no visible band was detected with the various V beta probes. As determined in the present study, the percentage of T-cells expressing a given V beta family must be > or = 10% to be detected with Northern blot. Thus, the percentage of V beta+ cells expressing V beta families which were explored only with Northern blot were within the same range as those of the 11 different TCR-V beta region families assessed with IHC, i.e. 1-10% of lymphoid cells. The results of the present study show that in HD there is no restricted T-cell V beta repertoire usage regardless of the detection of EBV. In addition, since the various V beta families are represented in T-cell subpopulations forming rosettes around H-RS cells, we conclude that the T-cells attracted by H-RS cells constitute a polyclonal population.

Abstract
PTCL represents a diverse group of histological entities that defy classification schemes based on normal T cell differentiation, differ in their clinical presentation and behave unpredictably. Genetic analyses of this phenotypically heterogeneous group have clearly shown that histologically defined PTCL may be subdivided on the basis of clonal gene rearrangements. The absence of clonal gene rearrangements in a significant proportion of PTCL cases has increased the complexity of classification. The data presented in this review suggest that a molecular classification would allow true reflection of PTCL aetiology, but carefully coordinated studies are required to evaluate the clinical usefulness of such a classification scheme.
