In vitro and in vivo evidence that the switch from calcineurin to mTOR inhibitors may be a strategy for immunosuppression in Epstein-Barr virus-associated post-transplant lymphoproliferative disorder. Kidney Int 2022; 102:1392-1408. [PMID: 36103953 DOI: 10.1016/j.kint.2022.08.025] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 08/02/2022] [Accepted: 08/12/2022] [Indexed: 01/12/2023]
Abstract
Post-transplant lymphoproliferative disorder is a life-threatening complication of immunosuppression following transplantation mediated by failure of T cells to control Epstein-Barr virus (EBV)-infected and transformed B cells. Typically, a modification or reduction of immunosuppression is recommended, but insufficiently defined thus far. In order to help delineate this, we characterized EBV-antigen-specific T cells and lymphoblastoid cell lines from healthy donors and in patients with a kidney transplant in the absence or presence of the standard immunosuppressants tacrolimus, cyclosporin A, prednisolone, rapamycin, and mycophenolic acid. Phenotypes of lymphoblastoid cell-lines and T cells, T cell-receptor-repertoire diversity, and T-cell reactivity upon co-culture with autologous lymphoblastoid cell lines were analyzed. Rapamycin and mycophenolic acid inhibited lymphoblastoid cell-line proliferation. T cells treated with prednisolone and rapamycin showed nearly normal cytokine production. Proliferation and the viability of T cells were decreased by mycophenolic acid, while tacrolimus and cyclosporin A were strong suppressors of T-cell function including their killing activity. Overall, our study provides a basis for the clinical decision for the modification and reduction of immunosuppression and adds information to the complex balance of maintaining anti-viral immunity while preventing acute rejection. Thus, an immunosuppressive regime based on mTOR inhibition and reduced or withdrawn calcineurin inhibitors could be a promising strategy for patients with increased risk of or manifested EBV-associated post-transplant lymphoproliferative disorder.

BMC Cancer 2009; 9:416.

Abstract
BACKGROUND Tumor-specific cytotoxic T cells and infiltrating lymphocytes are frequently found in tumor tissues in patients with nasopharyngeal carcinoma (NPC). Most patients with NPC, however, especially those with advanced stages, have a poor clinical prognosis despite conventional immunotherapy. The aim of this work was to examine the effect of indoleamine 2,3-dioxygenase (IDO), an immunosuppressive enzyme, on the lymphocyte function in NPC. METHODS The NPC cell line CNE2 was treated by interferon-gamma (IFNgamma) and the levels of IDO expression was analyzed by Western blotting and reverse phase high-performance liquid chromatography (HPLC). Lymphocytes from health human exposed to the milieu created by IDO-positive CNE2 cells and the lymphocyte cytotoxicity to target tumor cells was analyzed by standard lactate dehydrogenase (LDH) release assay. Additionally, expression of IDO was determined by Immunohistochemical assay in the tumor tissues form clinically evaluated NPC. RESULTS IDO expression was acutely induced in the NPC cell line CNE2 by low dose interferon-gamma (IFNgamma) or by co-incubation with activated lymphocytes. Exposure to the milieu created by IDO-positive CNE2 cells did not promote lymphocyte death, but lymphocyte cytotoxicity against target tumor cells was impaired. The suppression of lymphocyte cytotoxic function was fully restored when the conditioned medium was replaced by fresh medium for 24 h. In additionally, the IDO-positive cells were found scattered in the tumor tissues from patients with NPC. CONCLUSION Altogether, these findings suggest that IDO-mediated immunosuppression may be involved in the tumor immune evasion, and that blocking IDO activity in tumor cells may help to re-establish an effective anti-tumor T cell response in NPC.

Abstract
Answers to questions about frequency and repertoire of immune cells, relative contributions made by different types of immune cells toward the total Epstein-Barr virus (EBV)-directed response and the variation of such responses in healthy persons have been elusive because of disparities in assays, antigen presenting cells, and antigenic sources used in previous experiments. In this study, we addressed these questions using an assay that allowed direct comparison of responses generated by different types of cells of the immune system. This short-term (20-hour) ex vivo assay measured interferon-gamma production by blood cells in response to autologous EBV-transformed lymphoblastoid cell lines (LCLs). Our experiments defined the variation in responses among persons and clearly distinguished 10 healthy EBV-immune from 10 healthy EBV-naive persons. In EBV-immune persons, 33% of responding cells were CD4(+), 43.3% were CD8(+), and 12.9% were gamma-delta T cells. LCL-reactive CD8(+) T cells were only 1.7-fold more frequent than similarly reactive CD4(+)T cells. Responses by gamma-delta T cells were 6-fold higher in seropositive than in seronegative persons. Our findings emphasize the importance of CD4(+) and gamma-delta T-cell responses and have implications for immunotherapy and for identifying defects in T-cell populations that might predispose to development of EBV-associated lymphomas.

Abstract
Understanding the clonality and restricted usage of the TCR Vbeta repertoire of expanded T-cells induced by the chronic myelogenous leukemia (CML) associated antigen may be useful in helping design new immunotherapeutic strategies specifically for CML. T-cells from cord blood that had been stimulated by different stimulators (IL-2, PHA, CML cells, K562 cells and bcr-abl peptide) were amplified in vitro by liquid T-cell culture and the mixed lymphocyte and tumor cell culture (MLTC) method. By using the RT-PCR, the CDR3 segments of 24 variable region genes of TCR beta was analyzed in T-cells from 22 cases of cord blood before and after T-cell culture, to observe the usage of TCR Vbeta repertoire. The PCR products were further labeled with fluorescence and analyzed by the Genescan technique for the CDR3 size, to evaluating clonality of the detectable TCR Vbeta T-cells. Only a part of 24 Vbeta subfamily T-cells (3-15 subfamilies) could be detected, however, all of the 24 TCR Vbeta subfamily of T-cells were detected after in vitro culture with PHA or IL-2+anti-CD3 antibody. The number of expressed TCR Vbeta subfamilies was gradually reduced by prolonging the time of culture with CML-associated antigens. The restricted expression of TCR Vbeta subfamilies and oligoclonal expansion of Vbeta21 T-cells were found in cultured T-cells induced by CML cells, K562 cells or bcr-abl peptide. In conclusion, T-cells from cord blood may have the potential capability of proliferation in different TCR Vbeta subfamily T-cells, and the ability for restricted expression and clonal expansion, when T-cells were induced by CML associated antigen.

Abstract
The increasingly deeper understanding of how the immune system recognizes and destroys tumors promises to enable the development of new approaches for gene therapy and immunotherapy. However, a treatment that induces safe and potentially beneficial antitumor responses is expected to require stepwise refinements. As part of this challenge, assays are needed to measure specific antitumor immune responses in patients. This becomes problematic because most tumors express unknown tumor antigens and it is often difficult to obtain sufficient amounts of viable tumor material for in vitro assays. Recently it was demonstrated that RNA derived from tumor cells stimulated T cells in an antigen-specific manner. These studies have formed the basis for the development of dendritic cell vaccines that express tumor antigens following translation of tumor RNA. Therefore, it occurred to us that antigen-presenting cells transfected with total tumor RNA might also be valuable in monitoring the antitumor responses induced in patients who participate in clinical trials. To test this hypothesis, we developed a model in which Epstein-Barr virus (EBV)-transformed lymphoblastoid cell lines were used as a source of RNA. Since this RNA encodes for known EBV antigens, it was possible to determine whether the expected responses were observed. Our results show for the first time that T cells primed to APC transfected with RNA isolated from EBV-infected lymphocytes exhibited a fine specificity that enabled them to recognize individual EBV antigens.

Abstract
Dendritic cells (DCs) are the most potent antigen-presenting cells that are expected to be therapeutic agents for tumor immunotherapy. In this study, we generated DCs of sufficient number for DC-based immunotherapy from peripheral blood mononuclear cells (PBMC) in dogs. PBMC were cultured in the presence of phytohemagglutinin (PHA). On day 6, large adherent cells with dendrite-like projections were seen, and the number of these large cells with projections increased on day 8. These cells were positive for esterase staining. They expressed MHC class II, CD11b, CD8 and weakly CD4 on their surface. They tended to make contact with lymphocytes under culture conditions. We obtained about 2-5 x 10(6) of DCs from 10 ml of peripheral blood. These DCs phagocytosed HEK-293 cells by overnight co-culturing. These cells generated from PBMC are possible canine DCs and are applicable to clinical trials of DC-based whole tumor cell immunotherapy in dogs.
