Abstract
Epstein-Barr virus (EBV) is a ubiquitous human tumor virus associated with various malignancies, including B-lymphoma, NK and T-lymphoma, and epithelial carcinoma. It infects B lymphocytes and epithelial cells within the oropharynx and establishes persistent infection in memory B cells. With a balanced virus-host interaction, most individuals carry EBV asymptomatically because of the lifelong surveillance by T cell immunity against EBV. A stable anti-EBV T cell repertoire is maintained in memory at high frequency in the blood throughout persistent EBV infection. Patients with impaired T cell immunity are more likely to develop life-threatening lymphoproliferative disorders, highlighting the critical role of T cells in achieving the EBV-host balance. Recent studies reveal that the EBV protein, LMP1, triggers robust T-cell responses against multiple tumor-associated antigens (TAAs) in B cells. Additionally, EBV-specific T cells have been identified in EBV-unrelated cancers, raising questions about their role in antitumor immunity. Herein, we summarize T-cell responses in EBV-related cancers, considering latency patterns, host immune status, and factors like human leukocyte antigen (HLA) susceptibility, which may affect immune outcomes. We discuss EBV-induced TAA-specific T cell responses and explore the potential roles of EBV-specific T cell subsets in tumor microenvironments. We also describe T-cell immunotherapy strategies that harness EBV antigens, ranging from EBV-specific T cells to T cell receptor-engineered T cells. Lastly, we discuss the involvement of γδ T-cells in EBV infection and associated diseases, aiming to elucidate the comprehensive interplay between EBV and T-cell immunity.

Abstract
Multiple sclerosis (MS) is a chronic neurodegenerative autoimmune disease, characterised by the demyelination of neurons in the central nervous system. Whilst it is unclear what precisely leads to MS, it is believed that genetic predisposition combined with environmental factors plays a pivotal role. It is estimated that close to half the disease risk is determined by genetic factors. However, the risk of developing MS cannot be attributed to genetic factors alone, and environmental factors are likely to play a significant role by themselves or in concert with host genetics. Epstein-Barr virus (EBV) infection is the strongest known environmental risk factor for MS. There has been increasing evidence that leaves little doubt that EBV is necessary, but not sufficient, for developing MS. One plausible explanation is EBV may alter the host immune response in the presence of MS risk alleles and this contributes to the pathogenesis of MS. In this review, we discuss recent findings regarding how EBV infection may contribute to MS pathogenesis via interactions with genetic risk loci and discuss possible therapeutic interventions.

Abstract
Burkitt lymphoma (BL) is an aggressive form of B cell lymphoma that can affect children and adults. The study of BL led to the identification of the first recurrent chromosomal aberration in lymphoma, t(8;14)(q24;q32), and subsequent discovery of the central role of MYC and Epstein-Barr virus (EBV) in tumorigenesis. Most patients with BL are cured with chemotherapy but those with relapsed or refractory disease usually die of lymphoma. Historically, endemic BL, non-endemic sporadic BL and the immunodeficiency-associated BL have been recognized, but differentiation of these epidemiological variants is confounded by the frequency of EBV positivity. Subtyping into EBV+ and EBV- BL might better describe the biological heterogeneity of the disease. Phenotypically resembling germinal centre B cells, all types of BL are characterized by dysregulation of MYC due to enhancer activation via juxtaposition with one of the three immunoglobulin loci. Additional molecular changes commonly affect B cell receptor and sphingosine-1-phosphate signalling, proliferation, survival and SWI-SNF chromatin remodelling. BL is diagnosed on the basis of morphology and high expression of MYC. BL can be effectively treated in children and adolescents with short durations of high dose-intensity multiagent chemotherapy regimens. Adults are more susceptible to toxic effects but are effectively treated with chemotherapy, including modified versions of paediatric regimens. The outcomes in patients with BL are good in high-income countries with low mortality and few late effects, but in low-income and middle-income countries, BL is diagnosed late and is usually treated with less-effective regimens affecting the overall good outcomes in patients with this lymphoma.

Abstract
BACKGROUNDAdoptive transfer of donor-derived EBV-specific cytotoxic T-lymphocytes (EBV-CTLs) can eradicate EBV-associated lymphomas (EBV-PTLD) after transplantation of hematopoietic cell (HCT) or solid organ (SOT) but is unavailable for most patients.METHODSWe developed a third-party, allogeneic, off-the-shelf bank of 330 GMP-grade EBV-CTL lines from specifically consented healthy HCT donors. We treated 46 recipients of HCT (n = 33) or SOT (n = 13) with established EBV-PTLD, who had failed rituximab therapy, with third-party EBV-CTLs. Treatment cycles consisted of 3 weekly infusions of EBV-CTLs and 3 weeks of observation.RESULTSEBV-CTLs did not induce significant toxicities. One patient developed grade I skin graft-versus-host disease. Complete remission (CR) or sustained partial remission (PR) was achieved in 68% of HCT recipients and 54% of SOT recipients. For patients who achieved CR/PR or stable disease after cycle 1, one year overall survival was 88.9% and 81.8%, respectively. In addition, 3 of 5 recipients with POD after a first cycle who received EBV-CTLs from a different donor achieved CR or durable PR (60%) and survived longer than 1 year. Maximal responses were achieved after a median of 2 cycles.CONCLUSIONThird-party EBV-CTLs of defined HLA restriction provide safe, immediately accessible treatment for EBV-PTLD. Secondary treatment with EBV-CTLs restricted by a different HLA allele (switch therapy) can also induce remissions if initial EBV-CTLs are ineffective. These results suggest a promising potential therapy for patients with rituximab-refractory EBV-associated lymphoma after transplantation.TRIAL REGISTRATIONPhase II protocols (NCT01498484 and NCT00002663) were approved by the Institutional Review Board at Memorial Sloan Kettering Cancer Center, the FDA, and the National Marrow Donor Program.FUNDINGThis work was supported by NIH grants CA23766 and R21CA162002, the Aubrey Fund, the Claire Tow Foundation, the Major Family Foundation, the Max Cure Foundation, the Richard "Rick" J.

Abstract
Purpose While most adults are infected Epstein-Barr virus (EBV), 3-5% remain uninfected. The human leukocyte antigen (HLA) complex, which controls many pathogens, may influence infection and disease associated with EBV. Recent Findings Numerous EBV proteins and miRNAs down-regulate HLA class I and II expression on the cell surface. HLA class II functions as a receptor for EBV entry into B cells. Specific HLA class II alleles correlate with the susceptibility of B cells to EBV infection in vitro and with EBV seropositivity or seronegativity of humans. HLA class I polymorphisms correlate with development and severity of EBV infectious mononucleosis and with the risk of several virus-associated malignancies including nasopharyngeal carcinoma, Hodgkin lymphoma, and post-transplant lymphoproliferative disease. Significance These findings indicate that while EBV has evolved to use MHC class II as a receptor for virus entry, polymorphisms in MHC class II and class I influence virus infection and disease.

Abstract
The Epstein-Barr virus (EBV) nuclear antigen 1 (EBNA1) is generally expressed in all EBV-associated tumours and is therefore an interesting target for immunotherapy. However, evidence for the recognition and elimination of EBV-transformed and Burkitt's lymphoma (BL) cells by cytotoxic T lymphocytes (CTLs) specific for endogenously presented EBNA1-derived epitopes remains elusive. We confirm here that CTLs specific for the HLA-B35/B53-presented EBNA1-derived HPVGEADYFEY (HPV) epitope are detectable in the majority of HLA-B35 individuals, and recognize EBV-transformed B lymphocytes, thereby demonstrating that the GAr domain does not fully inhibit the class I presentation of the HPV epitope. In contrast, BL cells are not recognized by HPV-specific CTLs, suggesting that other mechanisms contribute to providing a full protection from EBNA1-specific CTL-mediated lysis. One of the major differences between BL cells and lymphoplastoid cell lines (LCLs) is the proteasome; indeed, proteasomes from BL cells demonstrate far lower chymotryptic and tryptic-like activities compared with proteasomes from LCLs. Hence, inefficient proteasomal processing is likely to be the main reason for the poor presentation of this epitope in BL cells. Interestingly, we show that treatments with proteasome inhibitors partially restore the capacity of BL cells to present the HPV epitope. This indicates that proteasomes from BL cells, although less efficient in degrading reference substrates than proteasomes from LCLs, are able to destroy the HPV epitope, which can, however, be generated and presented after partial inhibition of the proteasome. These findings suggest the use of proteasome inhibitors, alone or in combination with other drugs, as a strategy for the treatment of EBNA1-carrying tumours.

Abstract
Cytotoxic T lymphocytes (CTL) are an important protective mechanism in viral infection and can be effective against tumours. We have investigated the tumour-associated E6 and E7 genes of human papillomavirus type 16 as CTL targets. In H-2b mice we have defined epitopes in E6 and E7 which can readily generate CTL in vivo and we have shown that HLA-A2.1 transgenic mice can generate an HLA-A2.1-restricted response. We have been unable to reveal a primed CTL response in humans. These paradoxical findings imply that human papillomavirus may fail to stimulate a systemic CTL response and/or employ strategies for evading or down-regulating such a response.

Abstract
Tumor vaccine development aimed at stimulating the cellular immune response focuses mainly on MHC class I molecules. This is not surprising since most tumors do not express MHC class II or CD1 molecules. Nevertheless, the most successful targets for cancer immunotherapy, leukemia and melanoma, often do express MHC class II molecules, which leaves no obvious reason to ignore MHC class II molecules as a mediator in anticancer immune therapy. We review the current state of knowledge on the process of MHC class II-restricted antigen presentation and subsequently discuss the consequences of MHC class II expression on tumor surveillance and the induction of an efficient MHC class II mediated antitumor response in vivo and after vaccination.

Abstract
Regulation of the human MHC class I HLA-A11 promoter is governed by a complex array of regulatory elements. One of these elements, shown here to be critical for the transcriptional activity of the promoter, was used to screen a lambda gt11 library and allowed the identification of a cDNA which coded for the zinc finger protein ZFX. ZFX was shown to bind the sequences AGGGCCCCA and AGGCCCCGA, located respectively at positions -271 to -263 and -242 to -234 of the HLA-A11 promoter, with similar affinities through its three C-terminal zinc fingers. ZFX575, a short isoform of ZFX, activates transcription from the HLA-All promoter in a Leydig cell line.

Abstract
For decades cell biologists have relied on viruses to facilitate the study of complex cellular function. More recently, the tragedy of the AIDS epidemic has focused considerable human and financial resources on both virology and immunology, resulting in the generation of new information relating these disciplines. As the miracle of the mammalian immune system unfolds in the laboratory, the elegance of the mechanisms used by co-evolving viruses to circumvent detection and destruction by the host becomes inescapably obvious. Although many observation of virus-induced phenomena that likely contribute to the virus's escape of immune surveillance are still empirical, many other such phenomena have now been defined at the molecular level and confirmed in in vivo models. Immune modulators encoded within viral genomes include proteins that regulate antigen presentation, function as cytokines or cytokine antagonists, inhibit apoptosis, and interrupt the complement cascade. The identification of such gene products and the elucidation of their function have substantially strengthened our understanding of specific virus-host interactions and, unexpectedly, have contributed to the recognition of potent synergy between viruses, which can result in an unpredictable exacerbation of disease in co-infected individuals. Because many viral immune modulators clearly have host counterparts, viruses provide a valuable method for studying normal immune mechanisms. It is conceivable that an improved understanding of virus-encoded immunomodulators will enhance our ability to design reagents for use in therapeutic intervention in disease and in vaccine development.

Abstract
Group I Burkitt lymphoma (BL) lines retaining the original BL tumor cell phenotype are unable to present endogenously expressed antigens to HLA class I-restricted cytotoxic T cells (CTL) but can be recognized if the relevant HLA class I/peptide epitope complex is reconstituted at the cell surface by exogenous addition of synthetic target peptide. Endogenous antigen-processing function is restored in BL lines that have undergone Epstein-Barr virus (EBV)-induced drift in culture to the group III phenotype typically displayed by EBV-transformed lymphoblastoid cell lines (LCL) of normal B cell origin. We compared group I versus group III cells for their expression of proteasome components, transporter proteins and HLA-class I antigens, all of which are thought to be involved in the endogenous antigen processing pathway. By Western blot analysis, there were not consistent differences in the low molecular mass protein subunits of proteasomes (lmp)-2, lmp-7 and delta, although the mb-1 proteasome subunit was regularly present at higher levels in group I BL lines relative to group III lines or LCL. By contrast there were marked differences in the expression of peptide transporter-associated proteins (Tap), with down-regulation of Tap-1 and Tap-2 in 8/8 and 7/8 group I BL lines, respectively. Surface levels of HLA class I antigens were also consistently lower in group I cells; this was not associated with an intracellular accumulation of free HLA heavy chains, such as is seen in the Tap-deficient T2 processing-mutant line, but instead reflected a reduced rate of HLA class I synthesis in group I cells. Analysis of EBV gene transfectants of the B lymphoma lines BJAB and BL41 showed that the virus-encoded latent membrane protein-1 (LMP1), which is one of several EBV antigens expressed in group III but not in group I cells, was uniquely able to up-regulate expression both of the Tap proteins and HLA class I. Furthermore, this was accompanied by a restoration of antigen-processing function as measured by the ability of these cells to present an endogenously expressed viral antigen to CTL. These effects of LMP1 were similar to those induced in the same cell lines by interferon-gamma treatment. The results implicate both Tap and HLA class I expression as factors limiting the antigen-processing function of BL cells, and suggest that the accessibility of other EBV-associated malignancies to CTL surveillance may be critically dependent upon their LMP1 status.

Abstract
The present study shows a very highly diminished HLA-A2 cell surface expression with mendelian segregation in two nonrelated Spanish families. The associated haplotype included Cblank-B38-DRB1*1301-DQ6 in both families. cDNA sequence analysis in two members, one of each pedigree, revealed the presence of the commonest HLA-A2 allele (A*0201), without repetitive mutations that could indicate inappropriate or inefficient translation. Further, the coamplified 3'-untranslated region sequence was also the same described for HLA-A2. HLA-A transcription frequency by means of cDNA PCR-based cloning experiments and by Northern blotting pointed out a relatively low number of HLA-A2 mRNA molecules compared with the complementary HLA-A allele. 5'-Regulatory region sequences from two low-expressing HLA-A2 nonrelated individuals showed a unique and identical single point mutation at position -101 (T to C), when compared with all MHC class I alleles sequenced so far. Position -101 is located in the inverted CAT box associated with the MHC class I enhancer B. The fact that this is an extremely well-conserved position leads us to postulate that this change may be the only responsible for the defective expression of HLA-A2.

Abstract
T lymphocytes recognize their antigenic targets as peptides associated with major histocompatibility complex molecules. The HLA-A11 allele, a preferred restriction element for Epstein-Barr virus (EBV)-specific cytotoxic T-lymphocyte responses, presents an immunodominant epitope derived from the EBV nuclear antigen 4. Subpicomolar concentrations of a synthetic nonamer peptide, IVTDFSVIK, corresponding to amino acids 416-424 of the EBV nuclear antigen 4 sequence, can sensitize phytohemagglutinin-stimulated blasts to lysis by EBV-specific HLA-A11-restricted cytotoxic T-lymphocytes. We show that micromolar concentrations of this peptide induce assembly and surface expression of HLA-A11 in an A11-transfected subline of the peptide transporter mutant cell line T2. Using the IVTDFSVIK peptide and a series of synthetic nonamer peptides, differing from the original sequence by single amino acid substitutions, we have defined a motif for HLA-A11-binding peptides. This predicts the presence of a hydrophobic amino acid in position 2, amino acids with small side chains in positions 3 and 6, and a lysine in position 9. Using this motif, we have identified a peptide in the carboxyl-terminal end of wild-type p53, ELNEALELK, which is able to induce HLA-A11 assembly as efficiently as the IVTDFSVIK viral peptide.

Abstract
Spontaneously immortalized human mammary epithelial cells MCF-10A were transfected with an activated c-Ha-ras oncogene. Transfected cells (MCF-10T) acquire a malignant phenotype, as already reported. Studies of 125I-2'-deoxyuridine incorporation in cultures given graded doses of hydrocortisone (HC), cholera toxin (CT), epidermal growth factor (EGF), and transforming growth factor alpha (TGF-alpha) showed that though MCF-10T had become almost independent on exogenous EGF and TGF-alpha, they continued to respond to the synergistic effect of HC and CT plus EGF. Both lines were phenotypically characterized with an immunoradiometric assay in live cells. Expression of MHC class-I molecules, human milk-fat-globule-I antigen, and EGF receptor was reduced in ras-transfected cells, although other differentiation markers were unchanged. Exogenous EGF down-regulated the expression of functional EGF-R, selectively in transformed cells. TGF-alpha failed to modulate EGF-R. In contrast, HC strongly stimulated the expression of EGF-R while depressing MHC class-I molecules. Thus, it appears that in vivo HC may co-operate with TGF-alpha and EGF in promoting the growth of transformed mammary cells. This hormone might also favor the escape from immune surveillance by reducing the expression of surface differentiation markers.

Abstract
HLA class-I expression has been investigated by biochemical methods in 14 Burkitt lymphoma (BL) cell lines and the corresponding Epstein-Barr virus (EBV)-transformed lymphoblastoid cell lines (LCL) derived from the same individuals. Selective down-regulation of one or more HLA class-I specificities was demonstrated in 9 out of 14 BL lines. The defect was restricted to a single HLA-A allele in 3 of the lines (BL29, BL72, WW-I-BL). Four lines (BL28, BL37, BL41 and Jijoye M13) showed down-regulation of both HLA-A and -C alleles, and one (BL36) failed to express one HLA-C allele. Only one BL line (WW-2-BL) had lost one HLA-A and one HLA-B allele. The allele-specific defects were mainly detected in cell lines that had maintained the phenotypic characteristics of the original tumor. Expression of B-cell activation markers and the EBV-encoded nuclear antigen (EBNA)-2 correlated with up-regulation of the Cw4 allele in the P79 subline of the BL line Jijoye. Treatment with gamma-interferon (IFN) resulted in full or partial reversion of the HLA class-I defects in some of the cases but had no significant effect in others. This was not due to a cell-line-related unresponsiveness to IFN, nor did it reflect an allele-specific mode of regulation because the same allele could respond differently in different cell lines. The data suggest that defective expression of HLA class-I antigens, which appears to be more prevalent for alleles within the HLA-A and -C loci, is a common feature of BL cell lines. Different regulatory mechanisms appear to be involved.

Abstract
Burkitt lymphoma (BL) lines can be grouped according to phenotypic characteristics. Group I cells exhibit the phenotype of resting B cells and grow as single cells. Such lines can be Epstein-Barr-virus(EBV)-negative or -positive. Group II and group III cells are always EBV-positive, they express B cell activation markers, grow in aggregates and resemble in varying degrees lymphoblastoid cell lines (LCL). We studied three groups of BL lines for their capacity to interact with allogeneic lymphocytes. The results showed that as long as the lines have the group I phenotype, they do not stimulate allogeneic T lymphocytes irrespective whether they carry the EBV genome. The group II and III cells are stimulatory. Generally there was no correlation between sensitivity ot lymphocyte-mediated lysis and the phenotype of the lines. In one set of lines, the group I cells had higher sensitivity to both natural killer and lymphokine-activated killer effectors compared to the group II or III lines. However, such correlation could not be seen with the other two sets of lines. Among the phenotypic features investigated, expression of the adhesion molecules LFA-1 and LFA-3 correlated with the tendency for cell aggregation.

Abstract
A decreased expression of major histocompatibility complex (MHC) class I antigens is a common feature of many experimental and human tumors and can often be correlated with malignancy grade. In fact, reduction of class I antigens is associated in most tumors with an enhanced ability to elude immune surveillance. Loss of HLA-A,B,C antigens ranges from a decrease in the percentage of A,B,C-positive cells to selective loss of particular antigens and total loss of class I molecule expression. In man, this has been documented in melanomas, carcinomas, lymphomas, neuroblastoma and acute leukemias. The reduction in membrane antigens is generally associated with a parallel fall in immunoprecipitable intracellular proteins and the corresponding mRNAs in the absence of structural changes in the coding genes. The literature concerning the above mentioned topics is reviewed and discussed.
