Age-Related Immune Profile of the T Cell Receptor Repertoire, Thymic Recent Output Function, and miRNAs. BIOMED RESEARCH INTERNATIONAL 2020; 2020:5910823. [PMID: 33344643 PMCID: PMC7732372 DOI: 10.1155/2020/5910823] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 11/13/2020] [Accepted: 11/24/2020] [Indexed: 11/18/2022]
Abstract
Background T cell immunity plays a central role in the body's defense system, including maintaining homeostasis and preventing tumorigenesis and viral infection. Immune system functions degenerate with age, leading to immune senescence. Physiologically, immune senescence is characterized by a decrease in T cell receptor diversity, naive T cell deficiency, and alterations in T cell immune-related miRNAs. However, little is known about the characteristics of T cell immunosenescence in Chinese individuals. Results A significant decrease in the miR-17, miR-92a, and miR-181a levels in PBMCs was detected with age. The miR-92a and miR-181a levels were upregulated in CBMCs when comparing healthy individuals to group I (0~9 years), whereas miR-17 was downregulated. The sjTREC level in PBMCs was negatively correlated with age, and a sharp decrease in sjTRECs was found between groups I and II (10~19 years). Twenty-four TCR Vβ subfamilies could be detected in most samples, and most displayed polyclonality, while skewed expression of the Vβ subfamilies as well as an increased oligoclonal tendency was found with age. Similarly, the frequencies of the TCR Vγ and Vδ subfamilies decreased with age, and the alteration in clonality appeared to be stable at different ages. Conclusion We made the novel observation of T cell immunosenescence with age in Chinese individuals, which may provide information for immune targets to enhance the T cell immune response in immunotherapy settings for elderly patients.

Scand J Immunol 2020; 92:e12912. [PMID: 32458431 DOI: 10.1111/sji.12912] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Revised: 03/29/2020] [Accepted: 05/19/2020] [Indexed: 12/15/2022]
Abstract
Immune processes in liver transplantation remain poorly understood. Acute allograft rejection in liver transplantation is a kind of T cell-mediated inflammatory disease accompanied by inflammatory cell infiltration. However, the effect of acute allograft rejection on the immunological characteristics of TCRs in peripheral blood mononuclear cell is unknown. In this study, we characterized the pattern of the human T cell receptor beta chain (TRB) and immunoglobulin heavy chain (IGH) complementarity-determining region 3 (CDR3) repertoires via high-throughput sequencing in 11 acute allograft rejection (AG) cases, 23 patients with stable allograft liver function (ST) who had liver transplantation performed and 20 healthy controls (HC). The diversity of TRB-CDR3 was significantly reduced in the AG group compared with the ST group and healthy controls (HC). The CDR3 and N-addition length distribution were not significantly different between the AG and ST groups. However, N-addition length distribution was significantly changed compared to HC. It seemed that AG used more short N-additions and healthy people used more long N-additions in TRB-CDR3 repertoire. Our findings suggested that the TRB-CDR3 region of AG had distinctive V gene use compared with that of HC. The characteristics of ST seemed to be in between those of AG and HC although the difference is not significant. Cluster analysis showed that the TRB repertoire could not effectively distinguish AG from ST. This research might give to a better understanding of the immune process of liver transplantation.

Abstract
T cell inhibitory receptors play important role in maintaining T cell homeostasis. The feature of such negative costimulator signal transduction pathway in cord blood (CB) T cells remains unclear. In this study, the expression levels of T cell inhibitory receptors including programmed death-1 (PD-1), cytotoxic T lymphocyte antigen-4 (CTLA-4), T cell immunoglobulin mucin-3 (Tim-3), lymphocyte activation gene-3 (LAG-3) and B and T lymphocyte attenuator (BTLA) were characterized in CB and compared with peripheral blood (PB). Significant lower expression of PD-1, CTLA-4, LAG-3 and BTLA was found in CB, while similar expression level of Tim-3 was showed between CB and PB. Together, different expression pattern of such T cell inhibitory receptor in CB is worthy to further discuss their role on immune response when CB is used in cord blood stem cell transplantation as well as allogeneic chimeric antigen receptor T-cell producing.

Abstract
Preeclampsia (PE) is one of the major causes of maternal and perinatal mortality worldwide. This study aimed to determine the immunological characteristics of PE patients and normal pregnancy at the T cell receptor beta-chain (TRB) level by using high-throughput sequencing. High-throughput sequencing was performed to analyze the expression of TRB-CDR3 in circulating T cells. T cells were isolated from 36 healthy pregnant women, 24 patients with severe PE, and 18 patients with moderate PE. Rearranged mRNA sequences were assigned to their germline V, D, and J counterparts, and translated into proper amino acids by the IMGT database. In general, PE samples had more TRB-CDR3 reads and types than those of normal pregnant woman in the circulation, but the mean number of TRB-CDR3 reads and unique TRB-CDR3 reads in severe group was lower than that in the moderate group. In PE patients, the V7_9 and V20_1 gene loci were more prevalent than in healthy pregnant women. In addition, 4 kinds of TRB-CDR3 peptides were found to be highly relevant to the pathogenesis of PE. Of them, peptides matched to herpes simplex virus antigen-specific T cells were much lower in PE samples.

J Hematol Oncol 2016; 9:126. [PMID: 27863523 PMCID: PMC5116135 DOI: 10.1186/s13045-016-0353-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2016] [Accepted: 11/03/2016] [Indexed: 12/11/2022] Open
Abstract
Background Recent data have shown that γδ T cells can act as mediators for immune defense against tumors. Our previous study has demonstrated that persisting clonally expanded TRDV4 T cells might be relatively beneficial for the outcome of patients with T cell acute lymphoblastic leukemia after hematopoietic stem cell transplantation (HSCT). However, little is known about the distribution and clonality of the TRDV repertoire in T cell receptor (TCR) of γδ T cells and their effects on the clinical outcome of patients with acute myeloid leukemia (AML). The aim of this study was to assess whether the oligoclonal expansion of TCR Vδ T cells could be used as an immune biomarker for AML outcome. Findings γδ T cells were sorted from the peripheral blood of 30 patients with untreated AML and 12 healthy donors. The complementarity-determining region 3 (CDR3) sizes of eight TCR Vδ subfamily genes (TRDV1 to TRDV8) were analyzed in sorted γδ T cells using RT-PCR and GeneScan. The most frequently expressed TRDV subfamilies in the AML patients were TRDV8 (86.67 %) and TRDV2 (83.33 %), and the frequencies for TRDV1, TRDV3, TRDV4, and TRDV6 were significantly lower than those in healthy individuals. The most frequent clonally expanded TRDV subfamilies in the AML patients included TRDV8 (56.67 %) and TRDV4 (40 %). The clonal expansion frequencies of the TRDV2 and TRDV4 T cells were significantly higher than those in healthy individuals, whereas a significantly lower TRDV1 clonal expansion frequency was observed in those with AML. Moreover, the oligoclones of TRDV4 and TRDV8 were independent protective factors for complete remission. Furthermore, the oligoclonal expansion frequencies of TRDV5 and TRDV6 in patients with relapse were significantly higher than those in non-recurrent cases. Conclusions To the best of our knowledge, we characterized for the first time a significant alteration in the distribution and clonality of the TRDV subfamily members in γδ T cells sorted from AML patients. Clonally expanded TRDV4 and TRDV8 T cells might contribute to the immune response directed against AML, while oligoclonal TRDV5 and TRDV6 might occur in patients who undergo relapse. While the function of such γδ T cell clones requires further investigation, TRDV γδ T cell clones might be potential immune biomarkers for AML outcome.

Abstract
OBJECTIVE To compare the differences of immunological characteristics between newborn and adults, we performed high-throughput sequencing to reveal the diversity of umbilical cord blood and adult peripheral blood at both T-cell receptor beta chain (TRB) and immunoglobulin heavy chain (IGH) levels. STUDY DESIGN High-throughput sequencing was performed to analyze the expression of TRB-CDR3 and IGH-CDR3 in circulating T and B cells isolated from 20 healthy adults, 56 pregnant women, and 40 newborns. RESULTS Our results revealed different immunological characteristics between newborn and adults, such as distinctive complementarity determining region 3 (CDR3) lengths, usage bias of variable and joining segments, random nucleotide addition, a large number of unique CDR3 peptides, and a greater repertoire diversity. Moreover, each newborn had a distinctive TRB-/IGH-CDR3 repertoire that was independent of the maternal immune status. CONCLUSIONS This study presents comprehensive, unrestricted profiles of the TRB/IGH-CDR3 repertoire of newborns, pregnant women, and healthy adults at a sequence-level resolution. Our data may contribute to a better understanding of the immune system of newborns and benefit the efficient application of umbilical cord blood transplantation in future.

Abstract
Currently, arsenic trioxide therapy is widely used for the treatment of acute promyelocytic leukemia (APL), relapsed and refractory adult T-cell leukemia/lymphoma and myelodysplastic syndrome. Regarding the broad antitumor activity of arsenic, certain studies have been undertaken to test its efficacy in treating acute T-cell lymphoblastic leukemia (T-ALL) cell lines and patients; however, to the best of our knowledge, no reports document that arsenic is able to induce the remission of T-ALL patients. The present study reports the case of young male patient diagnosed with T-ALL, with no significant response to common chemotherapy regimens, who finally achieved complete remission without minimal residual disease (as detected by flow cytometry) due to arsenic treatment. This result is encouraging, and the present study has shown that malignant TCRαβ+ cell clones can be detected at the molecular level using reverse transcription-polymerase chain reaction (PCR) combined with the GeneScan technique. The result is mainly based on the T-cell receptor (TCR) Vβ1 clone (a 190-base pair PCR product that with the same complementarity determining region 3 length can be detected for all samples collected during various statuses) and on undetectable TCR Vγ subfamily members, at the time of disease diagnosis. It is important to analyze the dynamically changing TCR pool in leukemia patients during therapy. Although the molecular mechanism through which arsenic contributes to malignant clone elimination remains unclear in the case presented, the use of arsenic is expected to be effective for clinically treating refractory and relapsed T-ALL patients.

Abstract
T-cell receptor (TCR) repertoire analyses have been widely used to identify T cell populations of interest in cancer and autoimmunity and for characterizing immune repertoire reconstitution after hematopoietic stem cell transplantation (HSCT). Several decades of development and progress have led to the use of techniques for evaluating TCR repertoires in a more comprehensive, unbiased and fast manner, and the mechanisms of T cell immune reconstitution after HSCT and the new approaches used for recovering T cell repertoire diversity post HSCT have been more exhaustively documented to some degree. To better understand and characterize this progress, here we review recent studies on TCR repertoire diversity recovery in patients with leukemia and autoimmune disease who have received HSCT, impact factors and improvements in approaches for TCR repertoire recovery after HSCT.

Abstract
Defective T cell receptor (TCR) signaling resulting in lower T cell function plays a crucial role in the pathogenesis of T cell immunodeficiency in leukemia. Previous studies have indicated that lower TCRζ levels are a common characteristic of patients with leukemia, and upregulating TCRζ could partially recover T cell function. In this study, we characterized the effect of the stimulating factor induction on the TCRζ, Zap-70, and FcɛRIγ levels, IFN-γ secretion, and the distribution and clonal expansion of TCR Vβ subfamilies in CD3(+) T cells sorted from peripheral blood from acute myeloid leukemia (AML) patients. The induction included single stimulating factor or a combination with different cytokines (IL-2, IL-7, IL-2+IL-7, IL-7+IL-12, CD3, CD3+CD28 antibody, CD3+CD28 antibody+IL-2, and CD3+CD28 antibody+IL-7) at 72 h. The results showed that increased TCRζ and Zap-70 levels with deceased FcɛRIγ in T cells after induction, and different responses to cytokine in T cell from different cases may indicate the heterogeneity of T cells and different immune statuses in different AML cases. Increased IFN-γ levels in T cells from AML patients were detected after induction in the IL-12+IL-7, CD3+CD28+IL-2, and CD3+CD28+IL-7 groups. Moreover, the number of TCR Vβ subfamily T cells expressed was increased; however, all of the TCR Vβ subfamily T cells in the AML patients could not be completely recovered after induction. In conclusion, the cytotoxicity and activation function of T cells could be enhanced after induction by different stimuli accompanied by an increase in TCRζ and Zap-70 and recovery of the TCR Vβ repertoire in AML patients.

Abstract
Pleural tuberculosis (PLTB), a major cause of morbidity and mortality, is the most common extrapulmonary manifestation of active Mycobacterium tuberculosis (Mtb) in developing countries. Gamma delta T-cell receptor (TCR) repertoire of peripheral blood mononuclear cells (PBMCs) and pleural effusion mononuclear cells (PEMCs) and beta TCR repertoire from peripheral blood mononuclear cells (PBMCs) have been reported. However, a detailed different characteristic of beta TCR repertoire of mononuclear cells isolated from peripheral blood and pleural fluid in the immune response to Mtb infection should be further revealed. The TCR β-chain (TRB) from PBMCs and PEMCs from an untreated pleural tuberculosis patient was sequenced by the Illumina sequencing platform. A total of 96,758 and 124,130 unique complementarity-determining region 3 (CDR3) sequences were identified at the nucleotide level, encoding 69,488 and 99,095 peptide sequences, respectively. TCR profiling showed that TRBV20-1 family and TRBV20-1/TRBJ1-5 gene combination had a dominant expression in PEMCs, but not in PBMCs. Expansive expression of common CDR3 clonotypes was observed in PEMCs. CDR3 spectratyping analysis showed that few TRBV families had a significantly skewed pattern, with one peak or a few prominent peaks in the PBMCs. By contrast, some TRBV families showed oligoclonal or clonal expansion in the PEMCs. Here, we firstly profiled the TRB repertoire differences of PBMCs and PEMCs from one PLTB patient using high-throughput sequencing. And this study may provide new insight for the detailed and efficient study of TCR repertoire of PEMCs in the future.

Abstract
Graft versus host disease (GVHD) is the main complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Recent data indicated that regulatory T (Treg) cells might relate to GVHD, and such functions might be mediated by certain T-cell receptor (TCR) subfamily of Treg cells. Thus, we analyzed the distribution and clonality of the TCR Vα and Vβ repertoire of Treg cells from leukemia patients with and without GVHD after allo-HSCT. Numerous TCR Vα subfamilies, including Vα1, Vα9, Vα13, Vα16-19, and Vα24-29, were absent in Treg cells after allo-HSCT. The usage numbers for the TCR Vα and Vβ subfamilies in Treg cells from patients without GVHD appeared more widely. The expression frequencies of Vα10 or Vα20 between both groups were significantly different. Moreover, the expression frequency of TCR Vβ2 subfamily in patients without GVHD was significantly higher than that in patients with GVHD. Oligoclonally expanded TCR Vα and Vβ Treg cells were identified in a few samples in both groups. Restricted utilization of the Vα and Vβ subfamilies and the absence of some important TCR rearrangements in Treg cells may be related to GVHD due to a lower regulating function of Treg subfamilies.

Abstract
The immune modulatory effect of granulocyte colony-stimulating factor (G-CSF) on T cells resulted in an unexpected low incidence of graft-versus-host disease (GVHD) in allogeneic peripheral blood stem cell transplantation (allo-PBSCT). Recently, αβ(+) T cells are identified as the primary effector cells for GVHD. However, whether G-CSF could influence the repertoire of αβ(+) T cells (TRAV and TRBV repertoire) and CD3 genes remains unclear. To further characterize this feature, we investigated the effect of G-CSF mobilization on the T cell receptors (TCR) of αβ(+) T cells (TRAV and TRBV repertoire) and CD3 genes, as well as the association between the changes of TCR repertoire and GVHD in patients undergoing G-CSF mobilized allo-PBSCT. We found that G-CSF mobilization had an effect on the expression patterns, clonality and signal transduction of TRAV and TRBV repertoire. This alteration might play a role in mediating GVHD in G-CSF mobilized allo-PBSCT.

Abstract
Effects of Immunotherapy on the Distribution and Clonality of TCR Vγ and Vδ Subfamily T Cells in Allergic Rhinitis Patients
The aim of this study was to investigate the changes in the peripheral specific IgE level, distribution of TCR Vg and Vd subfamily T cells and mRNA expressions of TCR Vg I-III following specific immunotherapy (SIT) with house-dust-mite extract in allergic rhinitis (AR) patients. Ten AR patients undergoing SIT with house-dust-mite extract for 1 year were recruited. Quantitative analysis of immunofluorescence was performed to detect the serum specific IgE (sIgE) level before and after SIT; RT-PCR-genescan analysis was employed to detect the mRNA expressions of TCR Vg (I-III) and Vd (1-8) in the peripheral mononuclear cells followed by analysis of T cell clonality. Real-time quantitative PCR was applied to detect the expressions of TCR Vg I-III genes. Ten healthy volunteers served as controls. For AR patients, SIT treatment could improve the symptoms, but the serum sIgE level was not markedly decreased. Before SIT, the expressions of TCR Vg I-III gene were similar between AR patients and controls (P>0.05) but markedly decreased after SIT in AR patients (P<0.05 in TCR VgI and VgII). The expressions of TCR Vd (1-8) before and after SIT were 5.3±0.82 and 4.9±0.57, respectively, and that in healthy controls was 5.2±1.40. Vd1, 2, 3 and 6 were the most common genes found in these patients. Significant difference in the TCR Vd6 subfamily T cells was found between the two groups. Polyclonal or biclonal proliferation was found in the T cells of patients before SIT and in healthy controls, but oligoclonal proliferation in only 1 subject before SIT. After SIT, the proportion of patients with oligoclonal proliferation of T cells (6/10) was markedly increased (P<0.05). SIT for 1 year could alter the expressions of TCR Vg I-III genes, the distribution of TCR Vg and Vd T cells and the ways in which T cells proliferate. The early improvement of symptoms following immunotherapy might not be related to the serum sIgE content in AR patients, but associated with the TCR gd T cells, especially the TCR V d6 T cells.

Abstract
T-cell immunodeficiency is a common feature in cancer patients, which may relate to initiation and development of tumor. In expanding our previous observations in this area, we studied the repertoire of T-cell receptor beta variable region (TRBV) and T-cell proliferative history in CD4+ and CD8+ T cells from chronic myeloid leukemia (CML) patients. The expression and clonality analysis were performed by reverse transcription-polymerase chain reaction (RT-PCR) and GeneScan technique in peripheral blood mononuclear cells (PBMCs), CD4+ and CD8+ subsets of T cells. Nineteen CML cases in chronic phase were selected for this study and 17 healthy individuals served as controls. Marked restriction of TRBV repertoire was observed in both CD4+ and CD8+ T cells from CML. In most CML samples, clonally expanded T cells were identified in CD4+ and CD8+ T cells, predominantly in TRBV19 and TRBV21 (5/19) subfamilies. In conclusion, the restricted expression of TRBV subfamilies indicates the T-cell immunodeficiency in CML patients; however, clonally expanded T cells suggest a specific immune response to leukemia associated antigens.

Abstract
Umbilical cord blood (UCB) is used increasingly as a source of hematopoietic cells because of a lower risk of graft-versus-host disease (GVHD). Myeloablative conditioning before allogeneic umbilical cord blood transplant (allo-UCBT) results in thymic epithelial cell injury and T-cell immune deficiency. Full-term fetal blood cells were used as hematopoietic cells in a previous murine allo-UCBT model with a limited number of mice surviving the myeloablative conditioning. We designed a viable murine allo-UCBT protocol with platelet concentrate support. Keratinocyte growth factor (KGF) is a mitogen of thymic epithelial cells that promotes recovery of thymic epithelium when given before total body irradiation (TBI)-containing conditioning in experimental murine models. We hypothesized that KGF pre-administration would improve post-allo-UCBT thymopoiesis. To test this hypothesis, allo-UCBT recipient mice were given KGF or control saline prior to UCBT. Platelet concentrate support significantly improved the survival rate of murine allo-UCBT recipients. KGF administration significantly increased donor-derived T and natural killer T (NKT) cells at day +35 in spleens of allo-UCBT recipients. KGF administration also improved thymic function after allo-UCBT, resulting in higher copies of signal joint T-cell receptor rearrangement excision circles (sjTRECs) in splenocytes. Finally, we found that KGF pre-administration could enhance the graft-versus-leukemia effect. In conclusion, KGF can be administered safely to recipients of allo-UCBT to enhance T-cell immune reconstitution.

Abstract
Background Allogeneic hematopoietic stem cell transplantation (allo-HSCT) leads to a prolonged state of immunodeficiency and requires reconstitution of normal T-cell immunity. Signal joint T-cell receptor excision DNA circles (sjTRECs) are markers of developmental proximity to the thymus that have been used to evaluate thymic function related to T-cell immune reconstitution after HSCT. To assess the proliferative history in different T-cell receptor beta variable region (TRBV) subfamilies of T cells after HSCT, expansion of TRBV subfamily-naive T cells was determined by analysis of a series of TRBV-BD1 sjTRECs. Methods sjTRECs levels were detected by real-time quantitative polymerase chain reaction (PCR) in peripheral blood mononuclear cells (PBMCs) from 43 Chinese acute leukemia patients who underwent allo-HSCT. Twenty-three TRBV-BD1 sjTRECs were amplified by semi-nested PCR. Sixteen age-matched healthy volunteers served as normal controls. Results sjTRECs levels were low or undetectable in the first 6 weeks after allo-HSCT and increased after 8 weeks post HSCT; however, sjTRECs levels at week 20 post-HSCT were still less than normal controls. Frequencies of TRBV subfamily sjTRECs in PBMCs from recipients at week 8 post-HSCT (29.17 ± 20.97%) or at week 16 post-HSCT (38.33 ± 9.03%) were significantly lower than those in donors (47.92 ± 13.82%) or recipients at pre-HSCT (45.83 ± 14.03%). However, frequencies of TRBV subfamily sjTRECs in recipients at week 30 post-HSCT (42.71 ± 21.62%) were similar to those in donors and recipients at pre-HSCT. sjTRECs levels in donors had a positive linear correlation with sjTRECs levels in recipients within 8-12 weeks post-HSCT. Patients with acute graft-versus-host disease (GVHD) or chronic GVHD had profoundly reduced TRECs levels during the first year post-HSCT. Frequencies of BV22-BD1 sjTRECs and BV23-BD1 sjTRECs in patients with GVHD were significantly lower than those in recipients at pre-HSCT, and the frequencies of BV22-BD1 sjTRECs in patients with GVHD were significantly lower than those in donors. Conclusions Reconstitution of thymic output function resulted in a period of immunodeficiency, with low or undetectable TRECs after transplantation, although fludarabine-based dose-reduced conditioning regimens were used. GVHD could affect reconstitution of thymic output function and reduce sjTRECs levels and frequencies of TRBV-BD1 sjTRECs. Low frequency of BV22-BD1 and BV23-BD1 sjTRECs might be associated with GVHD.

Abstract
A DNA vaccine encoding PML-RAR alpha fusion gene is thought to be a promising approach for acute promyelocytic leukemia patients to enhance immune responses after attaining complete remission. In this study, we sought to enhance cellular immunity by coexpressing human interleukin (hIL)-2 genes. Successfully constructed plasmids PML-RAR alpha-hIL-2-pIRES, PML-RAR alpha-pIRES and hIL-2-pIRES were delivered intramuscularly in BALB/C mice at 14-day intervals for three cycles. The cellular immune responses with respect to the specific cytotoxicity of spleen cells; interferon-gamma secretion in sera, and the T-cell receptor rearrangement excision circles of thymocyte were significantly increased from PML-RARalpha-hIL-2-pIRES immunized mice. Our results indicate that a DNA vaccine with PML fusion gene segment and hIL-2 together might elicit increased cellular immune responses in mice.

Decreased level of recent thymic emigrants in CD4+ and CD8+T cells from CML patients. J Transl Med 2010; 8:47. [PMID: 20470401 PMCID: PMC2880023 DOI: 10.1186/1479-5876-8-47] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2009] [Accepted: 05/14/2010] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND T-cell immunodeficiency is a common feature in cancer patients, which may relate to initiation and development of tumor. Based on our previous finding, to further characterize the immune status, T cell proliferative history was analyzed in CD4+ and CD8+ T cells from chronic myeloid leukemia (CML) patients. METHODS Quantitative analysis of deltaRec-psiJalpha signal joint T cell receptor excision circles (sjTRECs) was performed in PBMCs, CD3+, CD4+ and CD8+T cells by real-time PCR, and the analysis of 23 TRBV-D1 sjTRECs was performed by semi-nested PCR. Forty eight CML cases in chronic phase (CML-CP) were selected for this study and 17 healthy individuals served as controls. RESULTS The levels of deltaRec-psiJalpha sjTRECs in PBMCs, CD3+, CD4+, and CD8+ T cells were significantly decreased in CML patients, compared with control groups. Moreover, the numbers of detectable TRBV subfamily sjTRECs, as well as the frequency of particular TRBV-BD1 sjTRECs in patients with CML were significantly lower than those from healthy individuals. CONCLUSIONS We observed decreased levels of recent thymic emigrants in CD4+ and CD8+ T cells that may underlay the persistent immunodeficiency in CML patients.

Abstract
Introduction The development of Philadelphia chromosome (Ph) negative acute leukemia/myelodysplastic syndrome (MDS) in patients with Ph-positive chronic myeloid leukemia (CML) is very rare. The features of restrictive usage and absence of partial T cell clones have been found in patients with CML. However, the T-cell clonal evolution of Ph-negative malignancies during treatment for CML is still unknown. Objective To investigate the dynamic change of clonal proliferation of T cell receptor (TCR) Vα and Vβ subfamilies in one CML patient who developed Ph-negative acute lymphoblastic leukemia (ALL) after interferon and imatinib therapy. Methods The peripheral blood mononuclear cells (PBMC) samples were collected at the 3 time points (diagnosis of Ph-positive chronic phase (CP) CML, developing Ph-negative ALL and post inductive chemotherapy (CT) for Ph-negative ALL, respectively). The CDR3 size of TCR Vα and Vβ repertoire were detected by RT-PCR. The PCR products were further analyzed by genescan to identify T cell clonality. Results The CML patient who achieved complete cytogenetic remission (CCR) after 5 years of IFN-α therapy suddenly developed Ph-negative ALL 6 months following switch to imatinib therapy. The expression pattern and clonality of TCR Vα/Vβ T cells changed in different disease stages. The restrictive expression of Vα/Vβ subfamilies could be found in all three stages, and partial subfamily of T cells showed clonal proliferation. Additionally, there have been obvious differences in Vα/Vβ subfamily of T cells between the stages of Ph-positive CML-CP and Ph-negative ALL. The Vα10 and Vβ3 T cells evolved from oligoclonality to polyclonality, the Vβ13 T cells changed from bioclonality to polyclonality, when Ph-negative ALL developed. Conclusions Restrictive usage and clonal proliferation of different Vα/Vβ subfamily T cells between the stages of Ph-positive CP and Ph-negative ALL were detected in one patient. These changes may play a role in Ph- negative leukemogenesis.

Abstract
BACKGROUND T cell immunodeficiency is a common feature in cancer patients, which may relate to initiation and development of tumor. Our previous study showed skewed expression of T cell receptor beta variable region (TRBV) subfamilies and clonal expansion of T cells in leukemia patients. In the present study, in order to further characterize the T cell immunity in acute myeloid leukemia (AML) patients, the level of recent thymic emigrants (RTE) was analyzed. MATERIALS AND METHODS Quantitative analysis of signal joint T cell recombination excision circles (deltaRec-psiJalpha sjTRECs) was performed in peripheral blood mononuclear cells (PBMCs) by real-time PCR (TaqMan), and the analysis of 23 TRBV-BD1 sjTRECs was performed by semi-nested PCR. Eighty-eight cases with AML were selected for this study; ten AML cases in complete remission (AML-CR) and 38 healthy individuals served as controls. RESULTS The levels of deltaRec-psiJalpha sjTRECs in PBMCs and CD3+ T cells were significantly decreased in AML patients, compared with healthy individuals and in patients in completive remission. Also the frequency of 23 TRBV-BD1 sjTRECs, and the number of detectable TRBV subfamily sjTRECs were significantly lower in AML patients than in healthy individuals. Moreover, the sjTRECs numbers and the frequency of TRBV-BD1 sjTRECs showed a progressive linear decline with age in AML patients. CONCLUSIONS The decreased numbers of universal (deltaRec-psiJalpha) and family-specific (TRBV-BD1) sjTRECs indicate that the severe T cell immunodeficiency in AML patients is associated with reduced levels of recent thymic emigrants. In patients achieving complete remission both sjTREC counts return to normal values indicating the recovery of thymic function. Better understanding of the mechanisms underlying persistent immunodeficiency in leukemia patients may lead to novel treatment strategies to enhance immune competence.

Abstract
Umbilical cord blood (CB) has been used as a valuable source of hematopoietic stem cells for allogeneic transplantation, specific CTL response and immunotherapy for decades. We previously analyzed the distribution and clonality of T-cell receptor alpha and beta variable region (TRAV) and (TRBV) of the subfamily T cell receptors in T cells from umbilical cord blood. Recent data indicated that gammadelta(+) T cells may play an important role in mediating the graft versus leukemia effect after stem cells transplantation and in anti-cancer response. In order to further characterize the repertoire of CB T-cells, the frequency of alphabeta(+) and gammadelta(+) T cells were examined in CB by FACS. The CDR3 size of 4 TRGV and 8 TRDV subfamily genes were analyzed in mononuclear cells (MCs) from 16 CB samples, using RT-PCR and genescan technique. To determine the expression level of TRGV subfamily genes, we performed quantitative analysis of TRGVI-III subfamilies by real-time PCR. Low percentage of CD3(+)TCRgammadelta(+) cells was observed in CB. The frequency of expression in TRGVI, TRGVII and TRGVIII in CBMCs was 93.75%, 81.25% and 56.25%, respectively. The mean value of the number of expressed TRDV subfamilies in CBMCs is higher than that from adult peripheral blood (PB) group. The frequently expressed members in CB were TRDV1 (100%), TRDV2 (93.75%), TRDV8 (93.75%) and TRDV3 (81.25%), respectively. The frequencies of TRDV5 and TRDV8 in CBMCs were significantly higher than those from PBMCs. Most of the PCR products of TRGV and TRDV subfamilies from 10 CB samples displayed polyclonal rearrangement pattern, whereas one or two PCR products from 6 CB samples showed oligoclonality or biclonality. In contrast, PCR products from 9 of 10 adult healthy controls contained at least an oligoclonal peak in different TRGV or TRDV subfamilies respectively. The pattern of TRGV subfamily expression level in CBMCs was TRGVI>TRGVIII>TRGVII, and in contrast, TRGVII>TRGVI>TRGVIII was found in PBMCs. In conclusion, our results indicate polyclonal and more diverse TRDV segment usage in CB gammadelta(+) T-cells. The pattern of TRGV expression levels in CB T cells was found to be quite different from the one in PB T cells. These findings are apparently the first report regarding the repression pattern of TRGV repertoire in CB. It also provides a detailed profile of the global TRGV and TRDV repertoire and TRGVI-III expression levels in cord blood T cells in Chinese subjects. The biological significance of the differences observed between CB and PB is at present obscure. However, this study will definitively contribute to understand the cellular immune features better and to exploit more efficiently the therapeutic potentials of CB.

Abstract
Graft-versus-host disease (GVHD), leukemia relapse, and immune deficiency remain the major limitations of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Donor natural killer cells (NK) and cytokines have good potential in GVHD prevention and immune reconstitution enhancement. Improved survival after allo-HSCT therefore requires effective prophylaxis to reduce GVHD and strategy to mediate graft-versus-leukemia (GVL) effect. We studied the administration of expanded donor NK cell infusion and interleukin-2 (IL-2) and IL-15 mixture treatment in a murine allo-HSCT model for its effects on GVHD, immune reconstitution and leukemia relapse. In the GVHD model, recipient mice were reconstituted with bone marrow (BM) cells and splenocytes via vein. In the leukemia model, recipient mice were inoculated with EL9611 leukemia cells via vein 8 d prior to transplant. NK cell infusion mice group had lower clinical GVHD scores and suffered less severe GVHD-associated weight loss than control mice group. 90% of control mice died of leukemia relapse within 52 d post-transplant. NK cell infusion and IL-2 and IL-15 treatment recipient mice had improved survival compared with control mice. NK cell infusion and IL-2 and IL-15 treatment recipient mice had also accelerated lymphoid immune reconstitution compared with control mice group. Expanded donor NK cell infusion and IL-2 and IL-15 treatment could promote lymphoid immune reconstitution, mitigate GVHD, and reduce leukemia relapse in allo-HSCT recipients. The findings may have important significance for complication prevention in clinical allo-HSCT.
