Abstract
BACKGROUND ccRCC is the prevailing form of RCC, accounting for the majority of cases. The formation of cancer and the body's ability to fight against tumors are strongly connected to Gamma delta (γδ) T cells. METHODS We examined and analyzed the gene expression patterns of 535 individuals diagnosed with ccRCC and 72 individuals serving as controls, all sourced from the TCGA-KIRC dataset, which were subsequently validated through molecular biology experiments. RESULTS In ccRCC, we discovered 304 module genes (DEGRGs) that were ex-pressed differentially and linked to γδ T cells. A risk model for ccRCC was constructed using 13 differentially DEGRGs identified through univariate Cox and LASSO regression analyses, which were found to be associated with prognosis. The risk model exhibited outstanding performance in both the training and validation datasets. The comparison of immune checkpoint inhibitors and the tumor immune microenvironment between the high- and low-risk groups indicates that immunotherapy could lead to positive results for low-risk patients. Moreover, the inhibition of ccRCC cell proliferation, migration, and invasion was observed in cell culture upon knocking down TMSB10, a gene associated with different types of cancers. CONCLUSIONS In summary, we have created a precise predictive biomarker using a risk model centered on γδ T cells, which can anticipate clinical results and provide direction for the advancement of innovative targeted therapies.

Tumor Lipids of Pediatric Papillary Renal Cell Carcinoma Stimulate Unconventional T Cells. Front Immunol 2020; 11:1819.

Abstract
Papillary renal cell carcinoma (PRCC) is a rare entity in children with no established therapy protocols for advanced diseases. Immunotherapy is emerging as an important therapeutic tool for childhood cancer. Tumor cells can be recognized and killed by conventional and unconventional T cells. Unconventional T cells are able to recognize lipid antigens presented via CD1 molecules independently from major histocompatibility complex, which offers new alternatives for cancer immunotherapies. The nature of those lipids is largely unknown and α-galactosylceramide is currently used as a synthetic model antigen. In this work, we analyzed infiltrating lymphocytes of two pediatric PRCCs using flow cytometry, immunohistochemistry and qRT-PCR. Moreover, we analyzed the CD1d expression within both tumors. Tumor lipids of PRCC samples and three normal kidney samples were fractionated and the recognition of tumor own lipid fractions by unconventional T cells was analyzed in an in vitro assay. We identified infiltrating lymphocytes including γδ T cells and iNKT cells, as well as CD1d expression in both samples. One lipid fraction, containing ceramides and monoacylglycerides amongst others, was able to induce the proliferation of iNKT cells isolated from peripheral blood mononuclear cells (PBMCs) of healthy donors and of one matched PRCC patient. Furthermore, CD1d tetramer stainings revealed that a subset of iNKT cells is able to bind lipids being present in fraction 2 via CD1d. We conclude that PRCCs are infiltrated by conventional and unconventional T cells and express CD1d. Moreover, certain lipids, present in pediatric PRCC, are able to stimulate unconventional T cells. Manipulating these lipids and T cells may open new strategies for therapy of pediatric PRCCs.

Abstract
Prior to the advent of VEGF-targeted therapies, renal cell carcinoma (RCC) was among the few solid tumors shown to respond to cytokine-based therapies such as interleukin-2 (IL-2) and interferon alpha. Previous work has shown that aminobisphosphonates, including zoledronic acid (ZA), are capable of activating human Vγ9 Vδ2 T cells in vitro, and these cells can be further expanded with IL-2. Moreover, these Vγ9 Vδ2 T cells have cytolytic activity in vitro to multiple human tumor cell lines. In the current report, we have conducted a pilot trial in patients with metastatic RCC, evaluating different doses of ZA in combination with low-dose IL-2 to determine whether combining these agents can promote in vivo proliferation of Vγ9 Vδ2 T cells and elicit an antitumor response. In 12 patients evaluated, no objective clinical responses were observed by RECIST criteria; however, two patients experienced prolonged stable disease. A modest increase in Vγ9 Vδ2 T-cell frequency could be detected by Day 8 of therapy in four of the nine patients who received at least one cycle of therapy, but not to the magnitude anticipated from preclinical models. Repeated administration of IL-2 and ZA resulted in both a diminished in vivo percentage of Vγ9 Vδ2 T cells as well as impaired expansion in vitro after the first cycle of therapy. These results suggest that repeated administration of IL-2 and ZA, at the doses and schedules used in this trial, may actually inhibit the proliferative capacity of Vγ9 Vδ2 T cell in patients with metastatic RCC.

Abstract
NK and γδ T cells can eliminate tumor cells in many experimental models, but their effect on the development of tumors caused by virus infections in vivo is not known. Polyomavirus (PyV) induces tumors in neonatally infected mice of susceptible strains and in adult mice with certain immune deficiencies, and CD8+ αβ T cells are regarded as the main effectors in anti-tumor immunity. Here we report that adult TCRβ knockout (KO) mice that lack αβ but have γδ T cells remain tumor-free after PyV infection, whereas TCRβ×δ KO mice that lack all T cells develop tumors. In addition, E26 mice, which lack NK and T cells, develop the tumors earlier than TCRβ×δ KO mice. These observations implicate γδ T and NK cells in the resistance to PyV-induced tumors. Cell lines established from PyV-induced tumors activate NK and γδ T cells both in culture and in vivo and express Rae-1, an NKG2D ligand. Moreover, these PyV tumor cells are killed by NK cells in vitro, and this cytotoxicity is prevented by treatment with NKG2D-blocking antibodies. Our findings demonstrate a protective role for NK and γδ T cells against naturally occurring virus-induced tumors and suggest the involvement of NKG2D-mediated mechanisms. Virus-induced tumors account for a large fraction of malignancies in both humans and mice. These tumors express viral antigens and have been thought to be controlled mostly by αβ TCR+ CD8 T lymphocytes that are specific for viral peptides. We found that mice lacking αβ T cells are protected from the formation of tumors induced by the small DNA virus polyoma (PyV) if they have γδ T and NK cells. Moreover, cell lines we established from the virus-induced tumors induced NK and γδ T cell activation, and expressed Rae-1, a cellular stress molecule which serves as ligand for NKG2D, an activating receptor on NK and γδ T cells. NK and γδ T cells seemed to mount antitumor but not antiviral responses, as their presence did not change the amount of persisting virus significantly. Our studies suggest that mice have a multipronged host defense against PyV-induced tumors that includes γδ T and NK cells in addition to αβ T cell responses. Merkel cell virus, a tumor causing polyomavirus in humans, is closely related to PyV with a similar biology, making it very important to understand mechanisms involved in host control of tumor development in the course of these life-long persistent infections.

Abstract
We performed a genomic study combining single-cell mRNA differential display and RNA subtractive hybridization to elucidate CD8 T-cell quiescence/ignorance. By comparing actively maintained quiescent CD8 T cells from liver tumour tumour-infiltrating lymphocytes (TILs) with quiescent T cells at the single-cell level, we identified differentially expressed candidate genes by high-throughput screening and comparative analysis of expressed sequence tags (ESTs). While genes for the T-cell receptor, tumour necrosis factor (TNF) receptor, TNF-related apoptosis inducing ligand (TRAIL) and perforin were down-regulated, key genes such as Tob, transforming growth factor (TGF)-beta, lung Krüpple-like factor (LKLF), Sno-A, Ski, Myc, Ets-2 repressor factor (ERF) and RE1-silencing transcription factor (REST/NRSF) complex were highly expressed in the quiescent TIL CD8 cells. Real-time polymerase chain reaction (PCR) further confirmed these results. A regulation model is proposed for actively maintained quiescence in CD8 T cells, including three components: up-regulation of the TGF-beta pathway, a shift in the MYC web and inhibition of the cell cycle.

Abstract
We previously showed that Vdelta2 T cells infiltrate renal tumors and can be expanded as potent cytotoxic effectors from peripheral blood mononuclear cells of most renal cell carcinoma (RCC) patients, using a structural analog of nonconventional T-cell receptor gamma9delta2 ligand, bromohydrin pyrophosphate, and interleukin-2 (IL-2). In this study, we have further investigated the differentiation status and the migration potential of circulating and tumor-infiltrating Vgamma9Vdelta2 T lymphocytes from RCC patients. The repertoire of tumor-infiltrating and peripheral Vgamma9Vdelta2 T cells from RCC patients was characterized by a dominant CD27- CD45RA- subset. These effector memory Vgamma9Vdelta2 T cells were efficiently expanded using bromohydrin pyrophosphate combined with IL-15, but not IL-2. In addition, peripheral Vgamma9Vdelta2 T cells from RCC patients present a modified chemotactic pattern compared with donors. After ex vivo activation, peripheral expanded Vgamma9Vdelta2 T cells acquire low-migration capacities toward renal cells. Tumor-infiltrating Vgamma9Vdelta2 T cells migrated with higher efficiency toward primary renal tumor cells. The traffic toward tumor cells required the CXCL12/CXCR4 interaction. Altogether, these results outline that those Vgamma9Vdelta2 effectors exhibit differential migration capacities according to their localization, their differentiation status, and the tumor microenvironment parameters that may influence their use in immunotherapy.

Abstract
Adoptive gammadelta T cell immunotherapy has moved briskly into clinical trials prompted by several small studies suggesting abundant accumulation of gammadelta T cells within renal cell carcinoma (RCC). In this study, we re-examined levels of gammadelta T cells within RCC tumors and correlated levels of these cells with pathologic features and outcome associated with this form of cancer. Tissues from 248 consecutive clear cell RCC tumors obtained from 2000 to 2003 were stained and quantified for total CD3+ and gammadelta T cells per mm2. Wilcoxon rank sum and Kruskal-Wallis tests were used to evaluate associations between T cell amounts and prognostic factors (age, gender, tumor size, stage, grade, tumor necrosis). Cox models were used to assess associations with RCC-specific death. Median numbers of total CD3+ and gammadelta T cells were 281/mm2 (interquartile range (IQR): 149-536) and 2.6/mm2 (IQR: 1.3-4.6), respectively. The median percentage of CD3+ T cells that were gammadelta T cells was 1.0% (IQR: 0.4-1.9). This low percentage of intratumoral gammadelta T cells was diluted even further with rising CD3+ T cell infiltration. Percentages of gammadelta T cells were not associated with even one single clinicopathologic feature examined. Median follow-up for this study was 3.1 years (48 patients died of RCC) and Cox analysis failed to demonstrate that gammadelta T cells (hazard ratio=1.02, p=0.25) were predictive of RCC-specific death. gammadelta T cells are rare and not recruited nor expanded within RCC tumors. Percentages of gammadelta T cells fail to correlate with any prognostic features of RCC nor specific death. As such, the role of gammadelta T cells in RCC immunobiology remains questionable.

Abstract
Dendritic cell (DC)-based tumor immunotherapy is widely known to elicit protective anti-tumor immune responses, although the safety and effectiveness have yet to be thoroughly explored. We reported that a disruption in the stratum corneum barrier resulted in enhanced permeability and alterations in the skin immune system in such a way that epidermal Langerhans cells (LCs) functioned as vigorous antigen presenters for T helper (Th) cells and cytotoxic T lymphocytes (CTLs). In both human and murine models, topical application of melanoma-associated antigen peptides onto stratum corneum barrier-disrupted skin, specifically induced tumoricidal immune responses in vivo and in vitro accompanying an increased expression of MHC and co-stimulatory molecules on LCs. In addition, for reasons of simplicity, safety and effectiveness, percutaneous peptide application has demonstrated a certain degree of feasibility in clinical approach in patients with melanoma. In the future, resolution of some of the outstanding issues concerning the selection of the most effective adjuvants in combination with barrier disruption and depletion of regulatory T (Treg) cell-mediated immune suppression would appear as essential to improve percutaneous melanoma immunotherapy.

Abstract
In murine tumors, innate immunity act as a trigger for the development of acquired immunity. The innate immune cells, natural killer (NK) and natural T (NKT) cells, generate the acquired immune cells, cytotoxic T lymphocytes (CTLs) and T helper (Th) 1 cells, by releasing interferon (IFN)-gamma. Regulatory T cells co-infiltrate with these tumoricidal effectors. In the innate phase, T cell receptor (TCR) gammadelta-bearing T (gammadelta T) and TCRalphabeta intermediate T cells are the regulators that suppress NK and NKT cells by elaborating interleukin (IL)-4, IL-10 and transforming growth factor (TGF)-beta. The acquired phase has Th3/T regulatory 1-like cells that inhibit CTLs and Th1 cells by TGF-beta. Thus, cytokines from regulatory T cells exert profound effects on tumor growth.

Abstract
Most gene expression methods often involve cumbersome steps or use expensive facilities. Additionally, some of the techniques, such as cDNA biochip, cannot define the sub-population of tissue from which the amplified cDNA was made. Here we present a rapid and high throughput screening method for analyzing the pattern of gene expression of tumor-infiltrating lymphocyte (TIL), which can minimize manipulations in cloned DNA sequencing and in bioinformatics. The pattern of TIL gene expression was studied in one ovarian cancer and one liver cancer. Our results have demonstrated that TILs have three different gene expression profiles: the first set of genes is involved in cell proliferation and mitogenic stimulation, such as c-myc and IL-8, LD78, MIP-1beta, insulin-induced protein and AH-receptor; the second set of genes includes those involved in attachment of lymphocytes to endothelium and extravasation into tumor tissues such as P-selectin ligand and integrin; and the third set, which includes genes such as the perforin, FAS ligand and granzyme B, is related to cytotoxic function to tumor cells. The patterns of TIL gene expression obtained from two specimens are marginally different and can be used in explaining the basis of molecular mechanisms regulating cellular interactions and cytotoxicity.

Abstract
It has been thought that natural killer (NK) cells appearing early in tumor lesions play a pivotal role in the innate immunity against tumor cells. Although NK cells serve as the first tumoricidal effector cells, they subsequently promote a shift in effectors from themselves to tumor-specific cytotoxic T lymphocytes (CTLs) that mediate the acquired immunity. The mechanism of this shift has not been fully elucidated, however, NK cell-derived T helper (Th) 1 cytokines such as interferon (IFN)-gamma seem to play a key role. Another NK-lineage, termed natural killer T (NK T) cells, may also participate in the innate period when they acquire the ability to secrete Th1 cytokines. Interleukin-4 (IL-4) and IL-10, belonging to Th2, and transforming growth factor-beta (TGF-beta), belonging to T regulatory (Tr) 1 cytokines, are known to suppress the development of NK, NK T cells, as well as CTLs and to block Th0 cell differentiation to Th1 cells, suggesting that tumor cells can evade the innate and acquired immunity by virtue of cells producing these inhibitory cytokines. In early tumor lesions of murine B16 melanoma, gammadelta T and alphabeta intermediate (int) T cells that co-infiltrate with NK and NK T cells can produce Th2 cytokines and inhibit the innate immunity. In MM2 mammary tumor-bearing mice, gammadelta T cells appearing both lesionally and systemically secrete Tr1-type cytokines and depress the acquired immunity. These Th2- or Tr1-type gammadelta T and alphabeta(int) T cells downregulate the tumoricidal cells by means of both their secreted cytokines and express major histocompatibility complex (MHC) class I molecules.

Abstract
Abstract
We examined whether γδ T and αβ T cells accumulating in early B16 melanoma lesions regulate NK and NK T cells that attack tumor cells. Freshly isolated and cultured tumor-infiltrating lymphocyte (TIL) populations of NK and NK T cells lysed B16 and produced IFN-γ, whereas γδ T and a large part of αβ T cell populations had no substantial cytotoxicity against B16 and secreted Th2 cytokines. Furthermore, the freshly isolated NK1.1+ TIL population exhibited a higher anti-B16 effect than did splenocytes. γδ T and αβ T cell populations dramatically inhibited the cytotoxicity of NK and NK T cells in an MHC Kb-dependent manner. Culture supernatant from γδ T and αβ T cell populations inhibited the proliferation of NK and NK T cell populations but did not affect their cytotoxicity, suggesting that the released Th2 cytokines are merely partly involved in the down-modulation of NK-lineage cells. NK1.1+ cells obtained from TIL of γδ T cell-depleted mice significantly lysed B16 cells compared with those from control mice. Finally, anti-Kb Fab mAb injected intralesionally at an early, but not at a late, stage of development of B16 melanoma inhibited tumor growth. These findings suggest that Th2-type γδ T and αβ T cells infiltrating in early B16 development inhibit the tumoricidal activity of NK-lineage cells using their class I molecules and partly their suppressive cytokines.
