Utility of Bulk T-Cell Receptor Repertoire Sequencing Analysis in Understanding Immune Responses to COVID-19. Diagnostics (Basel) 2022; 12:1222. [PMID: 35626377 PMCID: PMC9140453 DOI: 10.3390/diagnostics12051222] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 05/09/2022] [Accepted: 05/10/2022] [Indexed: 01/27/2023] Open
Abstract
Measuring immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 19 (COVID-19), can rely on antibodies, reactive T cells and other factors, with T-cell-mediated responses appearing to have greater sensitivity and longevity. Because each T cell carries an essentially unique nucleic acid sequence for its T-cell receptor (TCR), we can interrogate sequence data derived from DNA or RNA to assess aspects of the immune response. This review deals with the utility of bulk, rather than single-cell, sequencing of TCR repertoires, considering the importance of study design, in terms of cohort selection, laboratory methods and analysis. The advances in understanding SARS-CoV-2 immunity that have resulted from bulk TCR repertoire sequencing are also be discussed. The complexity of sequencing data obtained by bulk repertoire sequencing makes analysis challenging, but simple descriptive analyses, clonal analysis, searches for specific sequences associated with immune responses to SARS-CoV-2, motif-based analyses, and machine learning approaches have all been applied. TCR repertoire sequencing has demonstrated early expansion followed by contraction of SARS-CoV-2-specific clonotypes, during active infection. Maintenance of TCR repertoire diversity, including the maintenance of diversity of anti-SARS-CoV-2 response, predicts a favourable outcome. TCR repertoire narrowing in severe COVID-19 is most likely a consequence of COVID-19-associated lymphopenia. It has been possible to follow clonotypic sequences longitudinally, which has been particularly valuable for clonotypes known to be associated with SARS-CoV-2 peptide/MHC tetramer binding or with SARS-CoV-2 peptide-induced cytokine responses. Closely related clonotypes to these previously identified sequences have been shown to respond with similar kinetics during infection. A possible superantigen-like effect of the SARS-CoV-2 spike protein has been identified, by means of observing V-segment skewing in patients with severe COVID-19, together with structural modelling. Such a superantigen-like activity, which is apparently absent from other coronaviruses, may be the basis of multisystem inflammatory syndrome and cytokine storms in COVID-19. Bulk TCR repertoire sequencing has proven to be a useful and cost-effective approach to understanding interactions between SARS-CoV-2 and the human host, with the potential to inform the design of therapeutics and vaccines, as well as to provide invaluable pathogenetic and epidemiological insights.

Detection of submicroscopic disease in the bone marrow and unaffected testis of a child with T-cell acute lymphoblastic leukemia who experienced "isolated" testicular relapse. Int J Hematol 2009; 90:370-373. [PMID: 19688235 DOI: 10.1007/s12185-009-0393-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2008] [Revised: 07/01/2009] [Accepted: 07/07/2009] [Indexed: 10/20/2022]
Abstract
Testicular relapse has an impact on the prognosis of boys with acute lymphoblastic leukemia (ALL). Because isolated testicular relapse often precedes hematological relapse, systemic therapy is required in addition to local therapy. However, a rationale for the use of a combination of systemic chemotherapy and local therapy is unclear. A 12-year-old boy with T-ALL suffered from isolated testicular relapse at 27 months after diagnosis. He was successfully treated with systemic chemotherapy with orchiectomy and prophylactic irradiation to the contralateral testis. We retrospectively estimated the minimal residual disease in the bone marrow (BM) and the testis by detection of clone-specific T-cell receptor rearrangement of leukemic cells. We detected leukemic cells in the affected testis at relapse, as well as in the BM at initial diagnosis. In addition, we confirmed submicroscopic disease in the unaffected testis and the BM at relapse. We conclude that molecular analysis could reveal the submicroscopic disease in the patient with apparently isolated testicular relapse. This finding may provide a rationale for intensified systemic treatment of patients with isolated testicular relapse.

Abstract
TCR gamma/delta profiles were analyzed in 13 multiple myeloma patients after allogeneic non-myeloablative transplantation. Results show that both aGVHD and minimal residual disease (MRD) eradication did significantly affect TCR gamma/delta profile. During follow-up, six patients developed an aGVHD episode; in five of them, this event fitted with a modification of the TCR profile. Eleven patients achieved PCR-negativity during follow-up. In the 90% of them, the appearance of a new predominant TCR peak was concomitant to the disappearance of the IgH clone. These results suggest that different T gamma/delta populations would sustain GVM and GVH effects after non-myeloablative allogeneic transplant.

Abstract
DNA mixtures represent challenging samples that are rarely amenable to direct DNA sequence analysis and many of the strategies available to separate mixtures are both labor and time intensive. Denaturing high-performance liquid chromatography is an accurate and rapid approach for the detection and scoring of mutations. It can also be used to separate DNA mixtures. The technique relies on the chromatographic separation of crosshybridization products to isolate the individual components of a mixture. By eliminating secondary amplification and excessive manipulation prior to sequencing, denaturing high-performance liquid chromatography can streamline the analysis of conditions ranging from somatic mosaicism, microchimerism and mitochondrial heteroplasmy to evidentiary material containing mixtures of DNA encountered in forensic investigations.

Abstract
Analyzing the status of T-cell receptor (TCR) gene rearrangements has been an essential part of deciphering the stages of thymocyte development, understanding the alphabeta vs. gammadelta lineage decision, and characterizing T-cell leukemias. Methods such as PCR and quantitative Southern blotting provide useful information, but also have significant shortcomings such as lack of quantitation in the case of PCR and technical challenges in the case of Southern blotting. Here we describe a real-time PCR method that overcomes many of these shortcomings. This new method shows comparable results for the fraction of unrearranged TCRgamma and TCRbeta genes in human thymocytes and peripheral blood T cells as Southern blotting, and has the advantages of being simple to perform, highly quantitative, and requiring nanogram quantities of DNA. We also describe a real-time PCR method to quantitate T-cell receptor excision circles formed during TCRbeta rearrangements.

Abstract
The coexistence of autoimmune diseases and malignancies including lymphoproliferative diseases is often reported in the literature. Here we report an unusual case with two autoimmune diseases--myasthenia gravis (MG) and systemic lupus erythematosus (SLE) associated with unique palmoplantar keratoderma (PK) which preceded the development of multiple myeloma (MM) for twenty and seven years respectively. MG associated with non-malignant thymoma developed in 1981 and was successfully treated with thymectomy and physostigmine. Thirteen years later SLE was diagnosed and until now it is also accompanied by skin lesions corresponding to non-familial, diffuse palmoplantar keratoderma which is resistant to treatment. In 2001 the patient revealed inguinal and abdominal lymphadenopathy first diagnosed as extramedullary plasmacytoma and then as multiple myeloma on the basis of bone marrow infiltration and monoclonal gammopathy. Therapy with VAD regimen achieved complete remission of the MM and significant improvement of the skin changes lasting for six months. We failed to collect sufficient numbers of CD 34+ cells for peripheral blood stem cell transplantation. Now the malignancy is in partial remission after CHOP therapy and the skin lesions have returned to their initial status. To our knowledge, this is the first case to be reported with coexistence of these four diseases.

Abstract
In a European BIOMED-2 collaborative study, multiplex PCR assays have successfully been developed and standardized for the detection of clonally rearranged immunoglobulin (Ig) and T-cell receptor (TCR) genes and the chromosome aberrations t(11;14) and t(14;18). This has resulted in 107 different primers in only 18 multiplex PCR tubes: three VH-JH, two DH-JH, two Ig kappa (IGK), one Ig lambda (IGL), three TCR beta (TCRB), two TCR gamma (TCRG), one TCR delta (TCRD), three BCL1-Ig heavy chain (IGH), and one BCL2-IGH. The PCR products of Ig/TCR genes can be analyzed for clonality assessment by heteroduplex analysis or GeneScanning. The detection rate of clonal rearrangements using the BIOMED-2 primer sets is unprecedentedly high. This is mainly based on the complementarity of the various BIOMED-2 tubes. In particular, combined application of IGH (VH-JH and DH-JH) and IGK tubes can detect virtually all clonal B-cell proliferations, even in B-cell malignancies with high levels of somatic mutations. The contribution of IGL gene rearrangements seems limited. Combined usage of the TCRB and TCRG tubes detects virtually all clonal T-cell populations, whereas the TCRD tube has added value in case of TCRgammadelta(+) T-cell proliferations. The BIOMED-2 multiplex tubes can now be used for diagnostic clonality studies as well as for the identification of PCR targets suitable for the detection of minimal residual disease.

Abstract
Incomplete T-cell-receptor delta (TCR-delta) rearrangements are widely used for detection of minimal residual disease in childhood acute lymphoblastic leukemia. In a substantial number of cases both alleles are rearranged and polymerase chain reaction (PCR) products have either to be cloned or excised and reamplified from acrylamide gels. Here we describe a novel HPLC-based method for identification and characterization of clonal TCR-delta targets. Clonality of PCR amplified TCR-delta products was examined on a high-resolution micropellicular DNASep matrix (WAVE Nucleic Acid Fragment Analysis System, Transgenomic) and subsequently classified into clonal, biclonal or negative samples. Vdelta2-Ddelta3 and Ddelta2-Ddelta3 rearrangements were analyzed by denaturing high-performance liquid chromatography (DHPLC), using triethylammonium acetate as an ion-pairing reagent, with a linear acetonitrile gradient at 50 degrees C. Biclonal elution profiles consisted of two individual homoduplex peaks and one heteroduplex peak unique for each patient sample. For characterization of biclonal rearrangements DHPLC separated samples were subjected to a second run and individual clonal peaks were collected. A software-controlled fragment collector was arranged in tandem with the HPLC system for this purpose and purified PCR products were collected in a time-dependent manner. Fractions were air dried and subsequently sequenced directly. The specificity of the observed patient specific sequences was tested via real time quantitative PCR on a LightCycler system.

Abstract
Langerhans cell histiocytosis (LCH) is a rare neoplastic disease of specific dendritic cells which belong to the monocyte-macrophage system. The association of LCH with autoimmune disease is extremely rare and to our knowledge its coexistence with systemic lupus erythematosus (SLE) has not been described so far. We report a case of LCH affecting liver, spleen and abdomen lymph nodes, which developed in an adult female six years after diagnosis of SLE treated for a long time with prednisone. Histology showed infiltration of characteristic Langerhans cells with folded, grooved or lobulated nuclei with fine chromatin. In the background there were eosinophils, lymphocytes and CD-68-positive histiocytes. The neoplastic cells were S100p-immunopositive, but stained negatively for CD1a--probably as the result of overfixation of consulted material. CD-68 was present mostly in macrophages. Ultrastructurally, the tumour cells presented structures consistent with Birbeck granules. Clonal origin of neoplastic cells was shown using the HUMARA-PCR assay. The disease was refractory to treatment with high doses of prednisone and vincristine but complete response was achieved after treatment with caldribine combined with cyclophosphamide.

Abstract
Kimura's disease is a chronic inflammatory disorder of unknown etiology. A 62-year-old man presented with asymptomatic cervical lymphadenopathy associated with eosinophilia and increased serum immunoglobulin E. Excision biopsy showed Kimura's disease. Three years later another groin lymph node appeared and showed similar pathologic features. Polymerase chain reaction for Ig heavy chain and T-cell receptor (TCR) genes on DNA extracted from the cervical lymph node showed smear patterns. However, polymerase chain reaction for TCRdelta gene showed a clonal rearrangement. Sequencing showed a complete VDJ rearrangement (Vdelta1-N-Ddelta2-N-Jdelta), confirming the presence of a clonal T cell population. The same clonal TCRdelta rearrangement was amplified by polymerase chain reaction from the groin lymph node biopsied 3 years later. These results showed that the primary and recurrent lesions were biologically related. Furthermore, the presence of identical T cell clones in different sites and at different times suggested that a clonal T cell population might have contributed to the pathogenesis in this case of Kimura's disease.

Abstract
Infant t(4;11) acute lymphoblastic leukaemia (ALL) is a rare but cytogenetically well defined subgroup of immature B-cell precursor (BCP) ALL. To date, the configuration of their antigen receptor genes has not been studied in a large group of patients so far. In this study on 27 t(4;11) infant ALL, we have used standardized primer sets for the detection of all incomplete and complete immunoglobulin (Ig) heavy chain (IGH) rearrangements, as well as for the Ig light chain kappa (IGK), T-cell receptor delta (TCRD) and gamma (TCRG) rearrangements that are most common in childhood BCP ALL. Only 52% of cases displayed clonotypic antigen receptor gene rearrangements (IGH in 48%, IGK, TCRD and TCRG in 12%, 41% and 6% respectively). This low frequency suggests, together with the findings of predominantly incomplete DJh joins and monoallelic IGH rearrangements, that they are derived from an immature progenitor cell. As 48% of the t(4;11) infant ALL cases had no detectable antigen receptor gene rearrangements that could be used for minimal residual disease (MRD) analysis, we established an expression-independent, leukaemia-specific polymerase chain reaction (PCR) using the genomic sequence of the MLL-AF4 fusion genes. This method had high sensitivity and specificity and resulted in identical estimations of tumour loads when compared with IGH targets. Thus, genomic MLL-AF4 fusion genes are a good alternative target for the analysis of MRD in patients with t(4;11) leukaemias.

Abstract
We analyzed the minimal residual disease (MRD) in 50 children with acute lymphoblastic leukemia (ALL) by amplifying the clonally rearranged T-cell receptor (TCR) gamma/delta chain and/or immunoglobulin (Ig) kappa chain gene using the allele-specific-PCR method. All children were treated according to the protocols of the Children's Cancer and Leukemia Study Group of Japan (CCLSG). The patients were stratified into four risk-groups according to the leukocyte count and age at diagnosis. We prospectively sampled the patients' bone marrow at 1 month (point 1) and 3 months (point 2) after the initiation of chemotherapy and quantitated the MRD retrospectively. The results of MRD were closely related with the clinical outcome. The relapse rate of the patients MRD-positive at points 1 and 2 was 46% (6/13) and 86% (6/7), respectively, whereas those MRD-negative results at point 1 and 2 were 13% (3/13) and 3% (3/30), respectively. We found significant differences in the event-free survival between MRD-positive children and MRD-negative children like the reports, which have been made by BFM and EORTC groups. We conclude that MRD in an early phase of chemotherapy can be a good predictor of the prognosis of childhood ALL regardless of the protocol of chemotherapy or race.

Abstract
Human Tgammadelta lymphocytes constitute from 1 to 15% of all peripheral blood lymphocytes. Recent work has demonstrated that this population plays a major role in the pathogenesis of infectious and immune diseases. Increased numbers of gammadelta T cells have been found in affected skin from systemic sclerosis and chronic cutaneous lupus erythematosus patients. In our study, we have determined the numbers of Tgammadelta lymphocytes and their subpopulations in peripheral blood from 29 patients with systemic lupus erythematosus (SLE) and in 19 healthy volunteers using flow cytometry and specific monoclonal antibodies. The same cells in uninvolved skin from SLE patients and human controls using immunohistochemical analysis were estimated. T-Cell receptor (TCR) delta chain gene rearrangement was identified with primers for Vdelta1, Vdelta2 and Vdelta3 by the polymerase chain reaction. Statistical analysis showed a significantly decreased number of gammadelta T cells in SLE patients (26.4+/-16.9/microl) compared with the control group (55.3+/-20.6/microl (p < 0.001). The number of Vdelta2 TCR+ and Vgamma9 TCR+ subpopulations was also lower in SLE patients than in healthy persons. No statistical correlation between disease activity and the number of gammadelta T cells was demonstrated. The percentage of Tgammadelta lymphocytes in clinically normal skin from SLE patients was twice (22.0+/-9.4%) that found in the skin from healthy persons (11.1+/-5.5%) (p < 0.002). Higher percentages of the Vdelta2 TCR+ and Vgamma9 TCR+ subpopulation of lymphocytes were found in the skin from SLE patients. We have also found positive correlation between the percentage of Tgammadelta lymphocytes in skin and the activity of SLE (r=0.594, p < 0.001), and between subpopulation Vdelta3 TCR+ and disease activity (r=0.659, p< 0.001). In conclusion, the results of our studies demonstrate that, in patients with SLE, accumulation of Tgammadelta lymphocytes can be seen in clinically normal skin, and the percentage of these cells correlates with the activity of the disease.

Abstract
Coexistence of systemic lupus erythematosus (SLE) with low-grade non-Hodgkin's lymphoma (LGNHL) has been described occasionally in the literature with the potential pathogenetic role of monoclonal B CD5+/CD19+ cells. We report a case of LGNHL which developed 18 months after diagnosis of SLE. The monoclonal population of lymphocytes in the peripheral blood and bone marrow was CD5/CD19 negative but CD19/CD22 positive. The SLE responded well to treatment with prednisone and the course of the LGNHL was stable and cytotoxic treatment was not required.

Abstract
Rearrangements of the T-cell receptor (TCR) and immunoglobulin genes are considered as useful clonal markers in lymphoproliferative disorders of B- and T-cell lineage, and are frequently used for the detection of minimal residual disease (MRD). In this paper, we report on the unexpected results of an extensive analysis of TCR-delta chain gene rearrangement frequencies and patterns in leukaemic bone marrow DNA samples collected from 438 children with initial (n = 112) or relapsed (n = 326) acute lymphoblastic leukaemia (ALL). By applying a previously described multiplex polymerase chain reaction, the overall incidence of non-deleted TCR-delta gene rearrangements in ALL was 47% (206/438), 52% in initial ALL (58/112) and 45% in relapsed ALL (148/326). As expected, the majority of B-cell precursor (BCP) ALL had incomplete Vdelta2-Ddelta3 or Ddelta2-Ddelta3 TCR-delta gene rearrangements, whereas most T-ALL showed complete rearrangements of the TCR-delta gene locus (Vdelta1-Jdelta1, Vdelta2-Jdelta1, Vdelta3-Jdelta1). However, unexpectedly, 5/206 rearranged TCR-delta alleles in BCP-ALL showed a complete Vdelta-(Ddelta)-Jdelta gene rearrangement pattern, and 3/31 T-ALL had an incomplete recombination. Theoretically, complete TCR-delta gene rearrangements should not occur in cells other than T-lymphocytes and have only been reported once previously in BCP-ALL. The data contribute to the discussion about the reliable screening for clonal markers in ALL.

Abstract
We studied the impact of clonality, determined by analysis of Epstein-Barr virus genome termini, T-cell receptor genes and clonal chromosomal abnormality, on the clinical outcome in 32 patients with hemophagocytic lymphohistiocytosis (HLH). Of the cases studied, 23 cases were EBV-clonal, 15 cases were TCR-clonal and 7 cases were cytogenetically clonal. Thirty patients were treated with immuno-chemotherapy and/or multiagents' chemotherapy and 4 received bone marrow transplantation. All 7 cases, in which cytogenetically abnormal clones were identified, were fatal (3-year survival by Kaplan-Meier analysis; 14%, 95%CI: 0-40%). None of these 7 cases received bone marrow transplantation. On the other hand, the 3-year survival of 23 clonal EBV-positive HLH cases including 4 cytogenetically abnormal cases was 64 % (95%CI: 42-84%), while that of 15 TCR-clonal cases was 53% (95%CI: 26-78%). Our observations suggest that cytogenetically abnormal cases are at extremely high risk, requiring intensive immuno-chemotherapy followed by prompt and timely allogeneic bone marrow transplantation.

Abstract
Early response to therapy is an independent prognostic factor in childhood acute lymphoblastic leukemia. Although most patients have rapid early responses, as detected by morphology, 15% to 20% of patients have relapses. The authors evaluated residual disease by molecular methods on day 15 of minimal residual disease (MRD) therapy and compared these data with their recently established MRD-based risk stratification, defined by MRD levels 5 weeks after induction treatment and before consolidation. All 68 children treated according to current Berlin-Frankfurt-Münster (BFM) protocols went into morphologically complete remission after induction. There was a significant difference in outcome between children with rapid disease clearance and those with high levels of day-15 MRD (P = .035). Among patients with high levels of day-15 MRD, only the MRD-based risk stratification was predictive of the outcome. All patients with negative or low day-15 MRD had excellent prognoses and were in the MRD-based low-risk group. Thus, after only 2 weeks of treatment, the authors were able to identify a patient population of 20% who may benefit from the least intensive treatment.

Abstract
Immunoglobulin kappa (Igkappa) gene recombinations can be used - similarly to IgH rearrangements - as clonal markers in B-lineage leukaemias. Based on the extensive junctional diversity, these rearrangements represent valuable targets for the analysis of minimal residual disease (MRD). In order to provide a simple method for the rapid detection of leukaemia clone-specific kappa deleting element (Kde) mediated rearrangements, we developed a multiplex PCR reaction that is able to amplify the five most frequent rearrangements in one tube. Position of the amplimers were chosen to enable identification of the involved segments according to the size of the PCR product. This method was tested on 101 B-lineage leukaemias (71 childhood B-cell precursor acute lymphoblastic leukaemias (BCP ALL) and 30 chronic lymphocytic leukaemias (CLL)). 39 and 22 Kde rearrangements could be readily detected in 30 (44%) BCP ALL and 22 (56%) CLL, respectively. 36% of the Kde rearrangements in BCP ALL and 45% in CLL were intron recombination signal sequence (RSS)-Kde rearrangements. The other Kde rearrangements involved the Vkappa families: VkappaI in 36% and 50%, VkappaII in 32% and 16.7%, VkappaIII in 24% and 25%, and VkappaIV in 8% and 8.3% in BCP ALL and CLL, respectively. The sensitivity of the multiplex system was 10-2-10-3. We compared this multiplex PCR assay with multiple single PCR reactions using different sets of primer combinations. Thereby the number and types of rearrangements were confirmed in all cases. Clonality of rearrangements was proven by sequence analysis. Our data show that by this method clonal Kde rearrangements were rapidly detected and precisely identified.
