Abstract
Infection with cytomegalovirus (CMV) is highly prevalent in the general population and largely controlled by CD8pos T cells. Intriguingly, anti-CMV T cells accumulate over time to extraordinarily high numbers, are frequently present as tumor-resident 'bystander' T cells, and remain functional in cancer patients. Consequently, various strategies for redirecting anti-CMV CD8pos T cells to eliminate cancer cells are currently being developed. Here, we provide an overview of these strategies including immunogenic CMV peptide-loading onto endogenous HLA complexes on cancer cells and the use of tumor-directed fusion proteins containing a preassembled CMV peptide/HLA-I complex. Additionally, we discuss conveying the advantageous characteristics of anti-CMV T cells in adoptive cell therapy. Utilization of anti-CMV CD8pos T cells to generate CAR T cells promotes their in vivo persistence and expansion due to appropriate co-stimulation through the endogenous (CMV-)TCR signaling complex. Designing TCR-engineered T cells is more challenging, as the artificial and endogenous TCR compete for expression. Moreover, the use of expanded/reactivated anti-CMV T cells to target CMV peptide-expressing glioblastomas is discussed. This review highlights the most important findings and compares the benefits, disadvantages, and challenges of each strategy. Finally, we discuss how anti-CMV T cell therapies can be further improved to enhance treatment efficacy.

Abstract
A high percentage of malignant gliomas are infected by human cytomegalovirus (HCMV), and the endogenous expression of HCMV genes and their products are found in these tumors. HCMV antigen expression and its implications in gliomagenesis have emerged as a promising target for adoptive cellular immunotherapy (ACT) strategies in glioblastoma multiforme (GB) patients. Since antigen-specific T cells in the tumor microenvironments lack efficient anti-tumor immune response due to the immunosuppressive nature of glioblastoma, CMV-specific ACT relies on in vitro expansion of CMV-specific CD8+ T cells employing immunodominant HCMV antigens. Given the fact that several hurdles remain to be conquered, recent clinical trials have outlined the feasibility of CMV-specific ACT prior to tumor recurrence with minimal adverse effects and a substantial improvement in median overall survival and progression-free survival. This review discusses the role of HCMV in gliomagenesis, disease prognosis, and recent breakthroughs in harnessing HCMV-induced immunogenicity in the GB tumor microenvironment to develop effective CMV-specific ACT.

Abstract
Simple Summary Whether the human cytomegalovirus (HCMV) is present in samples obtained from patients with glioblastoma (GBM) has been a matter under debate during the last two decades. Many investigators have demonstrated the presence of HCMV proteins and nucleic acids in GBM tumors, while some have not been able to detect it. It is important to evaluate current data and resolve these issues to clarify the possible role of the HCMV in GBM tumorigenesis and if this virus can serve as a potential target of therapy for these patients. In the present systematic review, we aim to review published research studies with a focus to identify differences and similarities in methods used for the detection of the HCMV in GBM samples found to be positive or negative for HCMV. Our data suggest that the HCMV is highly prevalent in glioblastomas and that optimized immunohistochemistry techniques are required to detect it. Abstract Glioblastoma is a malignant brain tumor with a dismal prognosis. The standard treatment has not changed in the past 15 years as clinical trials of new treatment protocols have failed. A high prevalence of the human cytomegalovirus (HCMV) in glioblastomas was first reported in 2002. The virus was found only in the tumor and not in the surrounding healthy brain tissue. Many groups have confirmed the presence of the HCMV in glioblastomas, but others could not. To resolve this discrepancy, we systematically reviewed 645 articles identified in different databases. Of these, 81 studies included results from 247 analyses of 9444 clinical samples (7024 tumor samples and 2420 blood samples) by different techniques, and 81 articles included 191 studies that identified the HCMV in 2529 tumor samples (36% of all tumor samples). HCMV proteins were often detected, whereas HCMV nucleic acids were not reliably detected by PCR methods. Optimized immunohistochemical techniques identified the virus in 1391 (84,2%) of 1653 samples. These data suggest that the HCMV is highly prevalent in glioblastomas and that optimized immunohistochemistry techniques are required to detect it.

Abstract
Human cytomegalovirus (HCMV), as a ubiquitous and opportunistic virus, is a matter for consideration in broad-spectrum diseases, specifically in immunocompromised individuals. In recent decades, many studies that have evaluated the role of HCMV in inflammation and malignancies, especially in high-grade gliomas, have reported inconsistent results. Thus, this study was conducted to analyze 97 primary gliomas for human CMV UL83 gene and protein through TaqMan real-time polymerase chain reaction and immunohistochemistry, respectively. The results were positive for the UL83 gene and pp65 protein in 71% and 24% of samples, respectively. The frequency of HCMV was significantly higher in glioblastomas than other glioma grades (P < .01 and P < .05 for the UL83 gene and protein, respectively). In addition, the association between the prevalence of HCMV and aging strengthened the virus reactivation hypothesis in gliomas. In conclusion, a high frequency of HCMV infection was found in gliomas that correlated with tumor aggressiveness and age. This study recommends a thorough investigation to determine HCMV infection in gliomas to improve the existing knowledge of its role in glial tumors, its prognostic value, and possible efficient antiviral target therapy.

Abstract
Genipin, a compound derived from Gardenis jasminoides Ellis fruits, was demonstrated to be the specific uncoupling protein 2 (UCP2) inhibitor. UCP2 is a mitochondrial carrier protein that creates proton leaks across the inner mitochondrial membrane, thus uncoupling oxidative phosphorylation from adenosine triphosphate (ATP) synthesis. Several studies revealed that UCP2 is broadly over-expressed in leukemia, colorectal, lung, ovarian, prostate, testicular, and bladder cancers. However, the effect of genipin still needs to be elucidated in neurological malignancies. In this study, we investigated the anticancer effect of genipin in U87MG and A172 cell lines. The anticancer effect of genipin on these cell lines was measured by microculture tetrazoliumtest (MTT), Trypan blue exclusion, and colony formation assays, in the presence of various concentrations of genipin at different time intervals. We assessed apoptosis and measure intracellular reactive oxygen species (ROS) by flow cytometry. Expression of UCP2 and some of the genes involved in apoptosis was analyzed by real-time quantitative polymerase chain reaction (PCR). Results of the MTT assay showed that genipin moderately reduced metabolic activity of both cell lines in dose- and time-dependent manner. Result of Trypan blue exclusion test indicated that the viable cell count decreased in the treated group in a concentration-dependent manner. Genipin also significantly decreased colony formation ability of these cells in a concentration-dependent manner. Result of morphological changes showed that there were significant differences in cell number and morphology in treated groups as compared with the untreated groups. Flow cytometric analysis of U87MG and A172 cells with annexin V/propidium iodide staining, 48 hours after treatment with genipin, displays 22.4% and 26.1% apoptotic population, respectively, in treated cells, in comparison to 7.42% and 9.31% apoptotic cells of untreated cells. After treatment, UCP2 and B-cell lymphoma 2 (BCL 2 ) genes are downregulated, and BCL 2 associated X protein, BCL 2 antagonist/killer, BCL 2 interacting killer, and Cytochrome c genes are upregulated. Genipin treatment increased mitochondrial ROS levels and also induced apoptosis through caspase-3 upregulation. In conclusion, the antiproliferative effects of genipin on the growth of both glioblastoma cell lines have been shown in all of these assays, and genipin profoundly induced apoptosis in both cell lines via the UCP2-related mitochondrial pathway through the induction of intracellular ROS.

Abstract
Glioblastoma multiforme (GBM) is considered to be one of the most invasive human cancers, characterized by a high mortality rate and an average survival is <1 year. These tumors are highly aggressive and insensitive to conventional radio and chemotherapy. An interesting aspect of glioblastoma is the association of active human cytomegalovirus (HCMV) infection, which is evident by the presence of viral DNA, mRNA and protein level in most glioblastoma tissues. Although the presence of the HCMV infection in glioblastoma is well established, but the oncomodulatory role of HCMV is not defined yet. Enhancer of zeste human homolog 2 (EZH2) is a key protein of the polycomb repressive complex 2, epigenetic gene silencers. There have been several reports that EZH2 activity is essential in GBM pathogenesis. In our previous research, we have found a high rate of HCMV infection in a cohort of Iranian glioblastoma patients. In this study, we investigated the expression of EZH2 in HCMV-negative versus HCMV-positive GBM tissues in comparison to non-tumor tissues. The level of expression was determined by real time PCR and the differences were calculated using the Livac or 2(-ΔΔCt) and analysis of variance (ANOVA). Relative expression of EZH2 in HCMV-negative glioblastoma tissues were increased 6.053-fold compared to non-neoplastic brain tissues, while EZH2 gene expression was increased 41.098-fold in HCMV-positive glioblastoma tissues. ANOVA test showed that there is a significant difference in EZH2 expression between normal brain tissue, HCMV-negative and HCMV-positive glioblastoma tumors (p value = 0.0001). Our data indicate that EZH2 expression can be considered a risk factor in glioblastoma and EZH2 inhibitors may serve as potential new treatment in glioblastoma. This would be an interesting new field to investigate in more detail.
