Abstract
Triple-negative breast cancer (TNBC) is a highly aggressive and metastatic malignancy with poor treatment outcomes. The interaction between the tumor microenvironment (TME) and breast cancer stem cells (BCSCs) plays an important role in the development of TNBC. Owing to their ability of self-renewal and multidirectional differentiation, BCSCs maintain tumor growth, drive metastatic colonization, and facilitate the development of drug resistance. TME is the main factor regulating the phenotype and metastasis of BCSCs. Immune cells, cancer-related fibroblasts (CAFs), cytokines, mesenchymal cells, endothelial cells, and extracellular matrix within the TME form a complex communication network, exert highly selective pressure on the tumor, and provide a conducive environment for the formation of BCSC niches. Tumor growth and metastasis can be controlled by targeting the TME to eliminate BCSC niches or targeting BCSCs to modify the TME. These approaches may improve the treatment outcomes and possess great application potential in clinical settings. In this review, we summarized the relationship between BCSCs and the progression and drug resistance of TNBC, especially focusing on the interaction between BCSCs and TME. In addition, we discussed therapeutic strategies that target the TME to inhibit or eliminate BCSCs, providing valuable insights into the clinical treatment of TNBC.

Abstract
Results of immunotherapy in childhood solid cancer have been so far, with the exception of neuroblastoma, quite disappointing. Lack of knowledge of the immune contexture of these tumors may have contributed to the failure of immunotherapies so far. Here, we systematically reviewed the literature regarding the immunology of Wilms tumor (WT), one of the most frequent pediatric solid tumors of the abdomen. In Wilms tumor patients the high cure rate of >90%, achieved by the combination of surgery and radio-chemotherapy, is at the expense of a high early and late toxicity. Moreover, treatment-resistant entities, such as diffuse anaplastic tumors or recurrent disease, still pose unsolved clinical problems. Successful immunotherapy could represent a novel and possibly less-toxic treatment option. Employing the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) method of literature search, we analyzed the current knowledge of the immunological landscape of Wilms tumors in terms of tumor microenvironment, prognostic implications of single biomarkers, and immunotherapy response.

Abstract
In-depth knowledge of cancer molecular and cellular mechanisms have revealed a strong regulation of cancer development and progression by the inflammation which orchestrates the tumor microenvironment. Immune cells, residents or recruited, in the inflammation milieu can have rather contrasting effects during cancer development. Accumulated clinical and experimental data support the notion that acute inflammation could exert an immunoprotective effect leading to tumor eradication. However, chronic immune response promotes tumor growth and invasion. These reactions are mediated by soluble mediators or cytokines produced by either host immune cells or tumor cells themselves. Herein, we provide an overview of the current understanding of the role of the best-validated cytokines involved in tumor progression, IL-1, IL-4 and IL-6; in addition to IL-2 cytokines family, which is known to promote tumor eradication by immune cells. Furthermore, we summarize the clinical attempts to block or bolster the effect of these tumor-related interleukins in anti-cancer therapy development.

Abstract
INTRODUCTION Individuals affected by kidney cancer present a variety of immune abnormalities including cellular immune dysfunction, cytokine alterations and antigen presentation defects. On the other hand, spontaneous remissions are seen in up to 4% of renal cell carcinoma (RCC) patients and they are thought to occur via immune mechanisms. AREAS COVERED The authors comprehensively review the immune abnormalities in RCC patient and describe the kidney cancer immunotherapy candidates that are most advanced in their clinical development. Most relevant publications were identified through searching the PubMed database; the obtained information was thoroughly analyzed and synthesized. EXPERT OPINION As cure in advanced RCC cannot be accomplished with the current therapy standards such as tyrosine kinase inhibitors and mammalian target of rapamycin inhibitors, new treatment strategies are being sought. Enhancing the immune system represents an appealing avenue for kidney cancer therapy. Disappointingly, high-dose interleukin-2 and interferon-α cause severe toxicity and produce a questionable clinical benefit. The authors postulate that the 'durable responses' seen with these agents in only a handful of RCC patients represent spontaneous remissions. Promising immune strategies in RCC such as anti-cytotoxic T-lymphocyte-associated protein antibodies, anti-programmed cell death 1 (PD1)/PD1 ligand and tumor vaccines may expand the existing options for kidney cancer in future years.

Abstract
Recent pre-clinical and clinical studies have shown that stem cell-based therapies hold tremendous promise for the treatment of human disease. Mesenchymal stem cells (MSC) are emerging as promising anti-cancer agents which have an enormous potential to be utilized to treat a number of different cancer types. MSC have inherent tumor-trophic migratory properties, which allows them to serve as vehicles for delivering effective, targeted therapy to isolated tumors and metastatic disease. MSC have been readily engineered to express anti-proliferative, pro-apoptotic, anti-angiogenic agents that specifically target different cancer types. Many of these strategies have been validated in a wide range of studies evaluating treatment feasibility or efficacy, as well as establishing methods for real-time monitoring of stem cell migration in vivo for optimal therapy surveillance and accelerated development. This review aims to provide an in depth status of current MSC-based cancer therapies, as well as the prospects for their clinical translation.

Abstract
Malnutrition has marked consequences on surgical outcomes. Adequate nutrition is important for the proper functioning of all organ systems, particularly the immune system. Determination of the type and amount of nutrient supplementation and the appropriate route of nutrient delivery is essential to bolster the immune system and enhance the host's response to stress. Correct administration of immunonutrients could lead to reductions in patient morbidity following major surgery, trauma, and critical illness.

Abstract
The immune system plays a crucial role in the protection against tumor growth and progression. However, the activation of the immune system against the neoplastic cells does not always occur and, therefore, tumor cells are able to grow and progress continually in the host. It has now been realized that tumor cells themselves produce many of the important factors that are responsible for dismounting of effective immune response. These tumor-derived soluble factors invariably subdue the functions of almost every immune cell population. Therefore, we attempted to underline the mechanism of anti-tumor immune response and immunosuppression induced by tumor cells.

Abstract
The poor prognosis of patients with aggressive and invasive cancers combined with toxic effects and short half-life of currently available treatments necessitate development of more effective tumor selective therapies. Mesenchymal stem cells (MSCs) are emerging as novel cell-based delivery agents; however, a thorough investigation addressing their therapeutic potential and fate in different cancer models is lacking. In this study, we explored the engineering potential, fate, and therapeutic efficacy of human MSCs in a highly malignant and invasive model of glioblastoma. We show that engineered MSC retain their "stem-like" properties, survive longer in mice with gliomas than in the normal brain, and migrate extensively toward gliomas. We also show that MSCs are resistant to the cytokine tumor necrosis factor apoptosis ligand (TRAIL) and, when engineered to express secreted recombinant TRAIL, induce caspase-mediated apoptosis in established glioma cell lines as well as CD133-positive primary glioma cells in vitro. Using highly malignant and invasive human glioma models and employing real-time imaging with correlative neuropathology, we demonstrate that MSC-delivered recombinant TRAIL has profound anti-tumor effects in vivo. This study demonstrates the efficacy of diagnostic and therapeutic MSC in preclinical glioma models and forms the basis for developing stem cell-based therapies for different cancers.

Abstract
Transplantation of genetically engineered cells into the CNS offers immense potential for the treatment of several neurological disorders. Monitoring expression levels of transgenes and following changes in cell function and distribution over time is critical in assessing therapeutic efficacy of such cells in vivo. We have engineered lentiviral vectors bearing fusions between different combinations of fluorescent and bioluminescent marker proteins and used bioluminescence imaging and intravital-scanning microscopy in real time to study the fate of human neural stem cells (hNSCs) at a cellular resolution in glioma-bearing brains in vivo. Using Renilla luciferase (Rluc)-DsRed2 or GFP-Rluc-expressing malignant human glioma model, transduced hNSCs were shown to migrate extensively toward gliomas, with hNSCs populating gliomas at 10 d after transplantation. Furthermore, transduced hNSCs survived longer in mice with gliomas than in normal brain, but did not modulate glioma progression in vivo. These studies demonstrate the utility of bimodal viral vectors and real-time imaging in evaluating fate of NSCs in diseased models and thus provide a platform for accelerating cell-based therapies for CNS disorders.

Abstract
The clear evidence that tumor-infiltrating lymphocytes with anti-tumor activity exist in situ raises the question why renal cell carcinomas (RCCs) progress in vivo. A complex array of factors and pathways has been identified that impinges on innate and adaptive effector cells thereby inhibiting their activity against RCCs. The current picture of suppressive mechanisms that contribute to the failure of the immune system to control RCCs is reviewed here. Understanding these complex host-tumor interactions has broad implications for successful application of cytokine therapy and other forms of immunotherapy for RCC.

Abstract
In sequential studies, we compared immune reconstitution following high-dose chemotherapy (HDT) and stem cell transplantation (SCT) using intact mobilized peripheral blood stem cell (PSC) in intermediate grade non-Hodgkin's lymphoma (NHL) patients and CD34(+), lineage-negative (Lin(-)), Thy-1(lo) (CD34(+)Lin(-)Thy-1(lo)) stem cells in low-grade NHL patients. Cytokine expression and cellular phenotype and function were used as the basis of comparison. Despite differences in cellular composition of the stem cell grafts, immune reconstitution in both groups was similar. Significantly higher levels of type 1- and 2-associated cytokine messenger ribonucleic acid (mRNA) were observed both prior to and following transplant in the peripheral blood (PB) of both cohorts as compared to normal individuals. Similar levels of interleukin (IL)-4, IL-10, interferon-gamma (IFN-gamma), and tumor necrosis factor-alpha (TNF-alpha) messenger ribonucleic acid (mRNA) were seen in PB mononuclear cells following transplant with either product. In contrast, patients receiving isolated CD34(+)Lin(-)Thy-1(lo) cells expressed significantly higher IL-2 levels at all times examined post-transplant. Despite the high levels of cytokine gene expression and rapid restoration to pretransplant levels of CD3 cell number by day 30, T cell function and CD4:CD8 and CD4(+)CD45RA:CD4(+)CD45RO(+) ratios were significantly depressed in both cohorts compared to normal donors, and significantly lower in patients transplanted with CD34(+)Lin(-)Thy-1(lo) compared to patients receiving an intact PSC product. These data suggest that the peripheral tolerance in patients receiving HDT and an autologous SCT occurs independent of graft composition, although immune function and CD4 recovery are better facilitated by transplantation of an intact product.

Abstract
Therapeutic cancer vaccines, one form of active immunotherapy, have long been under investigation; consequently, several vaccine-based strategies have now moved from the bench to the clinical arena. Despite their tremendous promise, current vaccine strategies have shown only limited success in clinical settings, even in renal cell carcinoma (RCC), a prototypical malignancy for the application of immunotherapy. There is ample evidence that, especially in RCC, multiple immunosuppressive mechanisms exist that considerably dampen antitumor responses and weaken the activity of current immunotherapeutic regimens. Therefore, it will be necessary to reverse tumor-mediated immunosuppression before immunotherapies can successfully be applied. Recent insights into the nature and characteristics of the regulatory elements of the immune system have provided new opportunities to enhance vaccine-mediated antitumor immunity and, thereby, increase the chance for improving patient outcome. These new insights represent important considerations for the future design and application of more effective cancer vaccines against RCC and other cancers.

Abstract
Immunization of mice with the idiotype (Id) immunoglobulin from the murine B cell lymphoma, BCL1, before inoculating tumor cells can induce tumor dormancy. In this model, the tumor cells grow for a short period of time and then regress. The mice live for months or years with approximately 1 million tumor cells in their spleens. Some mice relapse due to decreases in the anti-Id antibody titers or the development of mutations in the residual tumor cells which render them refractory to negative signaling by the anti-Id antibody. In this study we determined whether we could eliminate the residual dormant cells by using a DNA vaccine against the Id or by immunomodulation of T-cell subsets in vivo. Our results demonstrate that dormancy can be maintained by further immunizations with either the BCL1 Id protein or DNA vaccine encoding its single-chain Fv fragment. We also found that a cytotoxic T-cell response was not induced by either in vivo administration of vaccine alone or by the vaccine plus interleukin-2. In addition the injection of anti-cytotoxic T-lymphocyte-associate antigen did not prolong dormancy. Finally, the in vivo administration of anti-CD25 to deplete regulatory T cells did not prolong dormancy. Dormancy in this model is dependent primarily upon anti-Id antibodies, our results suggest that other strategies to target residual dormant BCL1 cells are warranted. They also suggest that the elimination of dormant tumor may represent a greater challenge than the elimination of primary tumors.

Abstract
PURPOSE Few clinical prognostic factors have been identified for patients with metastatic renal cell carcinoma (MRCC), and no biomarker is known in this disease. Several endogenous cytokines have demonstrated interesting and significant correlations with survival in these patients. Our objective was to analyze the prognostic value of circulating vascular endothelial growth factor (VEGF), interleukin-10 (IL-10), and interleukin-6 (IL-6). PATIENTS AND METHODS Serum levels of IL-6, IL-10, and VEGF were measured in patients with MRCC. Their prognostic value for response to treatment and progression-free and overall survival was evaluated. Pretreatment samples were obtained from 138 patients of a large randomized multicentric trial. Endogenous cytokine levels were determined using immunoassays. Univariate and multivariate analyses were performed to evaluate the prognostic value of each factor further controlled by an internal validation test. Threshold values for serum IL-6 and VEGF were determined using the quartile method. RESULTS Serum IL-6 was detectable in 70% of the patients. IL-10 and VEGF were elevated in 8% and 71% of the patients, respectively. None of these circulating factors was correlated with response to treatment. IL-10 was not significantly correlated with progression-free or overall survival. Despite significant correlation with survival, VEGF was not an independent prognostic factor in the multivariate analysis. Finally, IL-6 was significantly correlated with progression-free survival and overall survival, and has prognostic value for overall survival. CONCLUSION Circulating IL-6 level appears to be an important independent prognostic factor in patients with MRCC; if confirmed in further studies, it could be considered for treatment decisions in these patients.

Abstract
These are indeed exciting times in the study of RCC. No longer should the clinician view RCC as a single entity, nor should the researcher pose basic questions without considering the biologic diversity of this tumor. The success of novel targeted therapeutic strategies will depend on the systematic study of genetic and epigenetic events and their relationship to aberrant protein expression and function, and an understanding of the permissive microenvironment that allows the tumor to be sustained. These studies must be correlated in a rigorous fashion to clinical parameters and outcomes. Progress against this elusive tumor will require a continuous translational dialogue between laboratory and clinical investigators.

Abstract
High-dose interferon is the only treatment approved by the FDA for adjuvant therapy of melanoma. However, its efficacy in this setting is questionable and its administration is associated with considerable toxicity. Many new agents are being tested clinically that hold the promise of greater efficacy and less toxicity but none of these have yet shown efficacy in controlled trials. These include biologics such as vaccines, cytokines, monoclonal antibodies, gene transfer, cellular therapies and angiogenesis inhibitors as well as chemotherapy combinations.

T helper type 1 (Th1)-type CD4(+) antitumor T cell help appears critical to the induction and maintenance of antitumor cytotoxic T lymphocyte (CTL) responses in vivo. In contrast, Th2- or Th3/Tr-type CD4(+) T cell responses may subvert Th1-type cell-mediated immunity, providing a microenvironment conducive to disease progression. We have recently identified helper T cell epitopes derived from the MAGE-6 gene product; a tumor-associated antigen expressed by most melanomas and renal cell carcinomas. In this study, we have assessed whether peripheral blood CD4(+) T cells from human histocompatibility leukocyte antigens (HLA)-DRbeta1*0401(+) patients are Th1- or Th2-biased to MAGE-6 epitopes using interferon (IFN)-gamma and interleukin (IL)-5 enzyme-linked immunospot assays, respectively. Strikingly, the vast majority of patients with active disease were highly-skewed toward Th2-type responses against MAGE-6-derived epitopes, regardless of their stage (stage I versus IV) of disease, but retained Th1-type responses against Epstein-Barr virus- or influenza-derived epitopes. In marked contrast, normal donors and cancer patients with no current evidence of disease tended to exhibit either mixed Th1/Th2 or strongly Th1-polarized responses to MAGE-6 peptides, respectively. CD4(+) T cell secretion of IL-10 and transforming growth factor (TGF)-beta1 against MAGE-6 peptides was not observed, suggesting that specific Th3/Tr-type CD4(+) subsets were not common events in these patients. Our data suggest that immunotherapeutic approaches will likely have to overcome or complement systemic Th2-dominated, tumor-reactive CD4(+) T cell responses to provide optimal clinical benefit.

Abstract
Tumor-infiltrating lymphocytes (TILs) from biopsies of 9 selected patients with pT1pN0M0 renal cell carcinoma (RCC) were analyzed at the clonal level for phenotypic distribution, cytokine secretion profile and antitumor cell proliferation and cytotoxicity. T-cell clones generated from RCCs were able to produce higher amounts of interleukin-4 (IL-4) and interferon-gamma (IFN-gamma) than the corresponding clones derived from peripheral blood mononuclear cells, thus suggesting a recruitment into tumors of T cells with peculiar functions. Moreover, CD4+ T-cell clones generated from TILs of nuclear grading 2 (G2)-type RCC patients produced significantly higher amounts of IL-4 and IL-10 and lower amounts of IFN-gamma than the corresponding clones generated from G1-type RCC and 2 renal angiomyolipoma (AML) patients. In addition, T-cell clones generated from lymphocytes infiltrating the peritumoral areas of G2-type, but not those from G1-type, RCC patients produced higher and lower amounts of IL-4 and IFN-gamma, respectively, than the corresponding clones derived from intratumoral T cells of the same patients. The proportion of T-cell clones derived from G2-type tumors and proliferating to autologous tumor cells (ATCs) was significantly lower than that of clones generated from G1-type RCC or AML patients. However, irrespective of their source, they exhibited similar cytokine profiles and produced comparable amounts of IL-4, IL-10 and IFN-gamma. Furthermore, the proportion and the production of both IL-4 and IFN-gamma of G2-type RCC-derived T-cell clones with cytotoxic activity against ATC were significantly lower than those of cytolytic clones generated from AML and G1-type RCCs. The concentrations of IL-4, IL-10 and IFN-gamma produced by the cytolytic clones from G2-type RCC were also lower than those produced by their noncytolytic counterparts obtained from the same patients. These data address the association of the nuclear grading of neoplastic cells with different local tumor-specific T-cell responses in RCC.

Abstract
Interleukin (IL)-12 enhances natural killer (NK) activity and induces interferon gamma (IFN-gamma) production. Recently, it was shown that IL-12 induces IL-10 production by human T cells and NK cells, as a negative feedback for IL-12-induced immune responses. In the present study, in order to investigate the functions of host immune cells existing in contact with cancer cells, we examined the effect of IL-12 on the induction of non-major histocompatibility complex (MHC)-restricted killer activity and of IFN-gamma and IL-10 production by pleural and peripheral blood mononuclear cells (MNC), isolated from 40 lung cancer patients and 20 control subjects. IL-12 induced significant killer activity in pleural MNC from lung cancer patients, as well as those in peripheral blood, against a small cell lung cancer cell line (SBC-3). In lung cancer patients, pleural MNC incubated with IL-12 produced more IFN-gamma than blood MNC. In addition, when stimulated with both IL-12 and IL-2, pleural MNC produced more IL-10 than blood MNC. This is the first study reporting that MNC from pleural effusions of patients with lung cancer can produce both type 1 (IFN-gamma) and type 2 (IL-10) cytokines following exposure to IL-2 and IL-12. These observations suggest that control of IL-10 production at the microenvironment level may be important for the efficacy of human lung cancer immunotherapy with IL-12.

Abstract
In recent studies, a crucial role for IFN-gamma in immunosurveillance of tumours and in IL-12 immunotherapy has been suggested. Nevertheless, little is known about the relevance of IFN-gamma and IL-12 for tumour surveillance in noncytokine immunotherapy. Adjuvant immunotherapy with viable BCG (Bacillus Calmette--Guérin) is considered to be the most powerful clinical treatment regimen of bladder cancer and is known to induce a variety of proinflammatory cytokines. Consequently, we analysed the antitumour response of IFN-gamma knockout (KO), IL-12 KO and IL-10 KO mice in the absence and presence of BCG immunotherapy in a syngeneic orthotopic model of bladder cancer. IFN-gamma KO and IL-12 KO mice died much earlier and by far smaller tumour inocula compared to wildtype mice, while this intrinsic antitumour response was not altered in IL-10 KO mice. BCG immunotherapy was effective in wildtype mice, but totally ineffective in IFN-gamma KO and IL-12 KO mice. BCG induced a massive local immune response in the bladder of treated animals. This response was markedly increased in IL-10 KO mice, which coincides with increased therapeutic efficacy in this mouse strain compared with wildtype mice. Our data establish a crucial role for a Th1 type immune response in the intrinsic and immunotherapeutic control of local orthotopic bladder cancer.

Abstract
The purpose of our prospective, case-controlled study was to investigate the hypothesis that women who are genetically programmed to produce high or medium levels of IL-10 were more likely to develop cancer of the uterine cervix than individuals genetically predisposed to low IL-10 production. The population was recruited from patients attending gynecological clinics at 2 hospitals in Harare, Zimbabwe. Laboratory tests were performed in the Departments of Immunology, Chemical Pathology and Medical Microbiology, Medical School, University of Zimbabwe, and simultaneously at the Department of Biological Sciences, University of Manchester, United Kingdom. Included in our study were 77 women with histologically proven cancer of the uterine cervix and 69 age- and parity-matched healthy women. All of the patients and healthy controls were from the Shona ethnic group that inhabits northern Zimbabwe. DNA was purified from cervical cytobrush samples obtained from women with cervical cancer. Control DNA was extracted from urine or peripheral blood samples from the healthy women. The Qiagen DNA extraction kit was used. Detection of allele A and/or G at -1082 in the promoter region of the IL-10 gene was carried out using the ARMS-PCR technique. Polymorphism in the amplified products was detected by gel electrophoresis in the presence of ethidium bromide and were bands visualized under UV light. The data comprise 77 women who developed invasive cervical cancer and 69 healthy women matched for age and parity. Patients with cancer were significantly (p = 0.001) more likely to be predisposed to produce higher (A/G) levels of IL-10. The genotype encoding for high (G/G) production of IL-10 was only observed in one cancer patient. The prevalence of low producers of IL-10 in the cancer group was significantly lower than in the healthy women. There were no high producers amongst the healthy women. These data suggest that the genetically acquired ability to produce higher levels of IL-10 may be a significant factor in the development of cervical cancer.

Abstract
Cytotoxic T lymphocytes (Tc) play a central role in cellular immunity against cancers. The cytotoxic potential of freshly isolated tumor-infiltrating lymphocytes (TILs) is usually not expressed. This suggests the possible existence of as yet unspecified and perhaps complex immunosuppressive factors or cytokines that affect the anti-tumor capacity of these TILs in the tumor milieu. In the present study, we demonstrated for the first time that TILs derived from human cervical cancer tissue consist mainly of Th2/Tc2 phenotypes. In vitro kinetic assays further revealed that cancer cells could direct the tumor-encountered T cells toward the Th2/Tc2 polarity. Cancer cells promote the production of IL-4 and down-regulate the production of IFN-gamma in cancer-encountered T cells. The regulatory effects of cervical cancer cells are mediated mainly by IL-10, and TGF-beta plays only a synergistic role. The cancer-derived effects can be reversed by neutralizing anti-IL-10 and anti-TGF-beta Abs. IL-10 and TGF-beta are present in cancer tissue and weakly expressed in precancerous tissue, but not in normal cervical epithelial cells. Our study strongly suggests important regulatory roles of IL-10 and TGF-beta in cancer-mediated immunosuppression.

Abstract
The mRNA expression of the cytokines IFN-gamma, IL-10 and TNF-alpha and the proapoptotic factor Fas ligand (FasL) was compared in freshly isolated CD4(+)and CD8(+)tumour-infiltrating lymphocytes (TIL) and simultaneously obtained autologous CD4(+)and CD8(+)peripheral blood lymphocytes (PBL) from 20 patients with renal cell carcinomas (RCC). TIL were isolated from mechanically disaggregated tumour material and PBL from peripheral blood by gradient centrifugation. The cells of the interphase were depleted from tumour cells with anti-human epithelial antigen magnetic beads and then positive selection was performed with anti-CD4 or anti-CD8 magnetic beads. In these pure lymphocyte preparations the constitutive expression of cytokine and FasL mRNAs was determined by using a PCR-assisted mRNA amplification assay. In the CD4(+)TIL from the 20 patients with RCC, levels of mRNAs encoding for IFN-gamma (P</= 0.001), IL-10 (P</= 0.05), and FasL (P</= 0.001) were significantly higher than in the autologous CD4(+)PBL. Comparison of CD8(+)TIL and CD8(+)PBL revealed a significant higher expression of IFN-gamma (P</= 0.001), IL-10 (P</= 0.01) and FasL mRNAs (P</= 0.001) in the former. However, TNF-alpha mRNA levels were significantly lower in the CD8(+)TIL than in the CD8(+)PBL (P</= 0.05). These data reflect a general in vivo activation of RCC infiltrating lymphocytes in the tumour surrounding.

Abstract
A dysregulation between cellular immunity (Th1 cells) and humoral immunity (Th2 cells) is a characteristic of cancerous diseases. Viscum album (VA) extract has an immunomodulatory effect and can be used in the treatment of cancer patients, either following or in combination with chemo- /radiotherapy. In this pilot study, we investigated the effect of VA extract on the serum levels and production of cytokines in a group of cancer patients undergoing treatment (N = 16) in comparison with healthy untreated controls (N = 11). The serum levels of interleukin-12 (IL-12) (p40 and p70), and the production of gamma interferon (IFN-gamma), interleukin 2 (IL-2), and interleukin-4 (IL-4) in peripheral blood mononuclear cells (PBMC) were measured in patients before treatment and on days 3, 5, 8, 15, and 21-29 during therapy, and in the control group at the same time intervals over a two-week period. Cytokine levels were determined by ELISA. In cancer patients, the serum levels of IL-12 (p40 and p70) before therapy were about 3-fold higher than in controls. They increased during therapy, with a borderline significance (Wilcoxon paired signed-rank test, P = 0.06). In PBMC the production of IFN-gamma and IL-2 (before therapy respectively 3-fold and 9-fold lower than in controls) increased significantly (Wilcoxon paired signed-rank test and Mann-Whitney U-test, P < 0.05) during treatment. In PBMC, IL-4 production was in the same range as in controls, and remained unaltered during therapy. In conclusion, the results of this study show that treatment with VA extract leads an increase in Th1 cytokine levels (IFN-gamma and IL-2), which suggests that cell-mediated immunity could be positively affected.

Abstract
OBJECTIVE In the present studies, we examined the role of immunoregulatory cytokine gene expression in immune reconstitution following high-dose chemotherapy and peripheral stem cell transplantation. MATERIALS AND METHODS We analyzed the steady-state mRNA cytokine levels and the immune phenotype and function in the peripheral blood mononuclear cells from intermediate-grade non-Hodgkin's lymphoma patients prior to and following high-dose chemotherapy and peripheral stem cell transplantation. RESULTS Significantly higher mRNA levels of both type 1 and type 2 cytokines and monokines were observed in patients undergoing high-dose chemotherapy and peripheral stem cell transplantation as compared with normal healthy individuals. Pretransplant mRNA levels of interleukin-2, -4, -8, -10, interferon-gamma and tumor necrosis factor-alpha were significantly higher than in normal individuals. In addition, on days 30 and 100 following transplantation interleukin-10 levels were significantly increased compared with pretreatment levels. In contrast, the levels of interleukin-2 mRNA and interferon-gamma were decreased significantly on day 365 compared with pretransplant levels. CONCLUSIONS The high levels of cytokine mRNA transcripts, both prior to and following peripheral stem cell transplantation, were not due to an increased cellular frequency; rather, they appear to be due to abnormal cellular activation. However, T-cell function is significantly depressed compared with normal donors, which is associated with significantly higher levels of cellular-dependent T cell inhibitory activity and, we suggest herein, high levels of interleukin-10, a type 2 cytokine.

Abstract
Interleukin (IL)-10 is known to be an autoregulatory factor of functions of monocyte macrophages. The purpose of this study was to determine whether IL-10 production by alveolar macrophages (AMs) is altered in patients with lung cancer. AMs were obtained by bronchoalveolar lavage from 25 patients with lung cancer and 14 control patients. The production of IL-10 by AMs was quantitated by enzyme immunoassay with or without stimulation with lipopolysaccharide (LPS). No significant difference in spontaneous and LPS-stimulated IL-10 production by AMs was observed between lung cancer patients and control patients (mean +/- SEM; 288.0 +/- 56.7 vs. 249.6 +/- 58.4 pg ml-1). IL-10 production of LPS-stimulated AMs was not impaired even in lung cancer patients with systemic metastasis. IL-4 failed to suppress LPS-induced production of IL-10 by AMs both in control patients and in lung cancer patients. In eight patients with lung cancer, IL-10 production by AMs was estimated before and after systemic chemotherapy and IL-10 production by LPS-stimulated AMs tended to increase after systemic chemotherapy from 152.3 +/- 51.9 to 278.0 +/- 112.8 pg ml-1. As IL-10 is a potent inhibitor of tumour angiogenesis, an important process of tumour progression, these results suggest that, even in advanced cancer patients, macrophages can produce potent angiogenesis inhibitor and systemic chemotherapy may augment this inhibitory activity in the lung.

Abstract
Hyaluronectin (HN) is a component of the extracellular matrix of connective tissue and is particularly associated with tumour inflammatory and connective stroma reaction, where it co-localizes with hyaluronic acid (HA). The HN/HA ratio has been suggested to be involved in tumour aggressivity and in the atherosclerosis process. IL-10 has also been described in atherosclerotic lesions and in cancer. HN production was therefore investigated in vitro in peripheral blood monocyte cell (PBMC) cultures, with and without bacterial lipolysaccharide (LPS) or interleukins (ILs) in the medium. HN was characterized in monocytic cell cytoplasm and in culture supernatants. Anti-IL-10 antibody suppressed the LPS-stimulating effect on HN production. HN synthesis rate was greatly increased in IL-10-activated cultures while IL-4 and IL-13, two other anti-inflammatory ILs, decreased HN release. In the presence of IL-10, the IL-4 or Il-13 inhibitory effect on HN synthesis was reversed. The results support the view that intratumoral release of IL-10 by monocytes may induce local production of HN. In conjunction with the known ability of HN to bind to HA, which is a cell migration and tumour invasion facilitating factor, and to inhibit HA-induced angiogenesis, our findings suggest that HN may modulate the effect of HA on atherosclerosis, angiogenesis and cancer development.

Abstract
BACKGROUND T helper type 1 cells (Th1), Th2, T cytotoxic type 1 cells (Tc1), and Tc2 play important immunoregulatory roles. Some recent studies have demonstrated that an elevated level of type 2 cytokines, such as interleukin-10, contributes to the ability of cancer cells to escape immunosurveillance. However, the impacts of Th1, Th2, Tc1, and Tc2 on tumor immunity are unclear. METHODS The authors evaluated the ratio of Th1 to Th2 and that of Tc1 to Tc2 among peripheral blood lymphocytes (PBL), regional lymph node lymphocytes (RLNL), and tumor-infiltrating lymphocytes (TIL) in 46 nonsmall cell lung carcinoma patients who had just undergone surgery; the evaluation involved detecting the intracellular interferon-gamma and interleukin-4 production with 3-color flow cytometry. They also evaluated the same ratios in the peripheral blood lymphocytes of 29 lung carcinoma patients with or without recurrence after surgery, and in the peripheral blood of normal volunteers. RESULTS The Th1-to-Th2 and Tc1-to-Tc2 ratios were significantly elevated in the tumor tissues. These ratios in the TIL were significantly elevated in the groups of patients with squamous cell carcinoma and a history of smoking. The Th1-to-Th2 and Tc1-to-Tc2 ratios were significantly depressed in the PBL of the patients with tumor recurrences. CONCLUSIONS A favorable Th1- and Tc1-dominant pathway is induced in the tumor tissues of operable patients, but their pathway can be expected to shift from Th1 or Tc1 to Th2 or Tc2 with the progression of cancer.

Abstract
Abstract
Oncofetal Ag (OFA) is a 44-kDa glycoprotein expressed during early to mid-gestation fetal development and re-expressed as a surface Ag by tumor cells soon after transformation. The Ag is detectable on all types of human and rodent tumors tested, but is undetectable on normal cells. In experimental animals it is autoimmunogenic and induces potentially protective T cell responses both after experimental immunization and during tumor development subsequent to carcinogenic insult. To determine whether this tumor-associated Ag is also immunogenic for human T lymphocytes, breast carcinoma patients’ peripheral blood mononuclear leucocytes were stimulated in vitro with autologous tumor cells in the presence of IL-2, γ-IFN, and IL-6 for 2 wk. The tumor-reactive cells were then restimulated and cloned by limiting dilution, and the clones were analyzed. We established 24, 19, 11, and 16 tumor-reactive clones from the four respective patients. Of those, 4, 6, 4, and 7, respectively, proliferated specifically to purified OFA. Both CD4 and CD8 OFA-specific clones were established, which responded equally well to purified OFA or 32- to 44-kDa immature laminin receptor protein. All were CD3+, TCR-αβ+. All CD4 clones secreted γ-IFN, but neither secreted IL-4 nor IL-10. Both IFN-γ-secreting cytotoxic CD8 clones and IL-10-secreting inhibitory CD8 clones were established. Thus, during human cancer development, the same types of OFA-specific effector and regulatory T cells are induced as during murine T lymphomagenesis.

Abstract
OBJECTIVE To assess the immunological relationship between tumour and host, focusing on the production of T-cell helper (Th) subset-derived cytokines in patients with renal cell carcinoma (RCC). PATIENTS AND METHODS The study comprised 35 patients (19 men and 16 women, mean age 56.9 years, range 39-78) with RCC, who had undergone nephrectomy. Using enzyme-linked immunosorbent assays, the levels of Th1-derived cytokines were measured, including interleukin (IL)-2 and interferon (IFN)-gamma, and Th2-derived cytokines, including IL-4, IL-5, IL-6, IL-10 and others. RESULTS There was no detectable IL-2 or IFN-gamma production (below the detection limit) except in two patients; IL-4 was produced in 18 patients (51%) and of these, 15 (43%) showed a higher level than the mean. IL-5 was produced in 12 patients (34%), all of whom showed a higher level than the mean, and IL-6 was produced in 32 (91%) of whom 10 (29%) showed a higher level than the mean. IL-10 was detected in 28 patients (80%) of whom 14 (40%) showed a higher level than the mean. The production of these cytokines was closely related to the stage and grade of malignancy. Furthermore, there were significant correlations between the levels of production of IL-4 and IL-5 (r2=0.92), IL-4 and IL-10 (r2=0.91), and IL-5 and IL-10 (r2=0.85). CONCLUSION The intratumoral immunological environment in patients with RCC shows a tendency to produce Th2-related cytokines in accordance with the stage and grade; this suggests a role in humoral but not in cellular immunity.

Abstract
Immunotherapy with interleukin 2 (IL-2) is not an effective anti-cancer treatment in the majority of patients with renal cell carcinoma (RCC), suggesting that the activation of cytotoxic T cells or NK cells may be impaired in vivo in these patients. The production of immunosuppressive factors by RCC was investigated. Using immunohistochemistry, IL-10 was detectable in 10 of 21 tumour samples tested. IL-10 was undetectable in the supernatant of cell lines derived from these RCCs. However, these cell lines or their conditioned medium (RCC CM), but not normal renal epithelial cells adjacent to the RCC or breast carcinoma cell lines, were found to induce IL-10, as well as prostaglandin E2 (PGE2) and tumour necrosis factor (TNF)alpha production by autologous or allogeneic peripheral blood mononuclear cells (PBMCs) and monocytes. IL-10 production induced by RCC CM was found to be dependent on TNF-alpha and PGE2 since an anti-TNF-alpha antibody (Ab) inhibited 40-70% of IL-10 production by monocytes, and the combination of anti-TNF-alpha Ab and indomethacin, an inhibitor of PGE2 production, inhibited 80-94% of RCC CM-induced IL-10 production by monocytes. The RCC CM of the five cell lines tested were found to induce a down-regulation of the expression of HLA-DR and CD86, as well as a strong inhibition of mannose receptor-dependent endocytosis by monocytes. The blockade of HLA-DR and CD86 expression was partially abrogated by indomethacin and anti-IL-10 Ab respectively, and completely abrogated by an anti-TNF-alpha Ab. The inhibition of mannose receptor-dependent endocytosis was partially abrogated by an anti-IL-10 Ab and completely abrogated by an anti-TNF-alpha Ab. These results indicate that RCCs induce IL-10, PGE2 and TNF-alpha production by monocytes, which down-regulate the expression of cell-surface molecules involved in antigen presentation as well as their endocytic capacity.

Abstract
White cell infiltration of solid tumors is an important prognostic indicator in malignant disease. Although macrophage infiltration is associated with good outcome in colorectal cancer, a high macrophage content is associated with poor prognosis in breast cancer. Suppressor macrophages prevent T cell activation in normal tissues such as mucosal linings exposed to continuous antigenic challenge. Interleukin 10 (IL-10), an immunosuppressive cytokine, inhibits macrophage co-stimulation of T cells. Suppressor macrophage numbers, T cell numbers and T cell activation status were assessed in cell suspensions obtained from fresh specimens of breast and colorectal tumours and matched normal tissues. IL-10 production by both malignant and matched normal tissue was also assessed. This study identified elevated numbers of suppressor macrophages in breast tumors compared to matched normal breast tissue. Colorectal tumors did not contain significant numbers of these cells. Although T cell numbers are increased in breast tumors, these cells do not appear to be fully activated, as assessed by major histocompatibility complex class II and Interleukin 2 receptor expression. In contrast, T cells in colorectal tumors exhibit greater expression levels of these markers. Breast tumors produce significantly higher levels of IL-10 than normal breast tissue whereas IL-10 levels in colorectal tumors are similar to normal colon tissue. Our findings of high suppressor macrophage numbers, high levels of IL-10 and poorly activated T cells in breast tumors compared to low suppressor macrophage numbers, low IL-10 and fully activated T cells in colorectal tumors may explain why high macrophage content is associated with poor prognosis in breast cancer and good prognosis in colorectal malignancy.

Abstract
Recently there has been considerable conjecture in the literature concerning a possible relationship between stress, depression and bereavement, and carcinoma. We shall propose a causal model in which the relationship between stress, depression and carcinoma is clarified. This relationship is grounded on dysregulation of the inflammatory cytokines in stress and depression. Stress is associated with increased expression of interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha), and reduced expression of IL-2, interferon-gamma (IFN-gamma), major histocompatability complex (MHC) class II molecules and natural killer cell activity (NKA). Depression is associated with elevated IFN-gamma and IL-1 beta, downregulated IL-2, and reduced NKA. Most organ-related carcinomas are associated with elevated TNF-alpha, which inhibits the activity of protein tyrosine phosphatase (PTPase), the enzyme that initiates activation of the MHC class I pathway. Sustained elevation of TNF-alpha inhibits the activity of PTPase which results in diminished expression of the MHC class I antigen on the cell surface and thus, malignant cells escape immune surveillance. Therefore, stress and depression can foster tumor progression by means of inhibiting the expression of MHC class I and II molecules and through the reduction of NKA.

Abstract
Abstract
Vaccination with a poorly immunogenic/nonimmunogenic tumor fails to protect the host from a subsequent challenge with the same tumor. The mechanisms underlying the failure of these tumors to sensitize therapeutic T cells are not clearly understood, but the inability of host T cells to recognize tumor has been implicated. In this study, vaccination with the poorly immunogenic B16BL6-D5 (D5 H-2b) tumor fails to generate therapeutic T cells from the tumor vaccine-draining lymph nodes (TVDLN) in our adoptive immunotherapy model. However, if vaccination is performed with an allogeneic MHC class I gene (H-2 Kd)-modified tumor, the T cells obtained from the TVDLN are therapeutic after activation with anti-CD3 and IL-2. Lymph nodes (LN) draining both D5 and D5-Kd tumor vaccines contained increased numbers of cells with reduced expression of L-selectin (L-selectinlow/−) compared with naive LN. This implies that vaccination led to sensitization of T cells even in LN draining the unmodified D5 tumor. L-selectinlow/− cells from D5-Kd, but not D5, TVDLN were therapeutic in our animal model. No antitumor activity was seen in the high level L-selectin T cells. L-selectinlow/− T cells exhibited tumor-specific cytokine release that was type 2 (IL-4, IL-10) following vaccination with native D5 and type 1 (IFN-γ) following vaccination with gene-modified D5-Kd. Our data suggest that the failure of unmodified D5 to generate therapeutic T cells is not due to an inability to recognize tumor Ags, but, rather, to the induction of an immune response that is ineffective in mediating tumor regression, i.e., immune deviation.

Abstract
1. Several immunological abnormalities have been found in schizophrenia but their significance still remains largely unknown. In this study the authors analyzed mitogen-stimulated interleukin (IL)-2, Interferon gamma (IFN)-gamma and IL-10 (type 2 cytokine) production in a sample of 37 chronic schizophrenic patients as compared with a sample of 40 age and sex-matched controls with the aim to evaluate whether patients belonging to different diagnostic subtypes (i.e. paranoid patients vs non paranoid patients) could be immunologically different from each other. 2. The findings indicate that paranoid patients produce less IL-10 than the others and thus, from an immunological viewpoint, they are more similar to healthy controls. 3. Furthermore, neuroleptic medications were observed to differently affect IL-2 production; this preliminary finding might stimulate further studies aiming to get a link between different drug profile of action both in terms of clinical and receptorial profile and different immunological effects.

Abstract
Renal cell carcinoma (RCC) is a solid tumour of the kidney and is the most common renal neoplasm. Despite the presence of tumour infiltrating lymphocytes (TIL) in RCC, these tumours continue to progress in vivo suggesting a poor host immune response to the tumour, and the suppression of TIL effector function. Cytokines are key molecules that modulate the function of T cells. The possibility is investigated that the local production of cytokines in RCC contributes to immunosuppression of TIL. The expression of pro-inflammatory (IFN-gamma/IL-2) and immunosuppressive (IL-10/TGF-beta) cytokine mRNA transcripts was determined in RCC, normal kidney and peripheral blood of RCC patients using a semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) with cytokine-specific primers. Following Southern blot hybridization of the PCR products with internal radiolabelled oligonucleotide probes, cytokine transcript levels were measured by densitometry and expressed relative to the glyceraldehyde-3-phosphate dehydrogenase densitometry score. With the exception of IL-10, there were no differences in expression of cytokine mRNA transcripts between the peripheral blood of patients and normal healthy individuals. It was found that TGF-beta transcripts were well represented in normal kidney and RCC. In contrast, the expression of IFN-gamma transcripts, while low in the majority of samples, was significantly increased in RCC when compared to normal kidney (P=0.05). The IL-2 and IL-10 transcripts showed a more variable expression in normal kidney and RCC, with no significant differences in expression between the sample groups. The data demonstrating pro-inflammatory and immunosuppressive cytokine expression in RCC do not support a prominent immunosuppressive cytokine profile in these tumours.

Abstract
The high capacity of the T cell hybridoma BW-19 to metastasize to the spleen, despite its high and moderate sensitivity to lysis by macrophages and natural killer (NK) cells, respectively, appears to be linked to its capacity to suppress local resident NK cell and macrophage activity. Such suppression of splenic NK cell and macrophage activity is accompanied by an increased production of the p40 subunit of interleukin-12 (IL-12) by spleen cells. Closer examination revealed that most of the p40 subunit is present under the form of the homodimer (p40)2, whereas the heterodimeric form of IL-12 is present only in small amounts. Since (p40)2 is known to be a strong antagonist of IL-12-mediated effects, i.e., NK cell activation and interferon-gamma (IFN-gamma) secretion, the increased production of (p40)2 after BW-19 cell inoculation may contribute to the suppression of NK cell and macrophage activity. In addition, we found that the high production of (p40)2 in our tumor model was accompanied by a drastic decrease in IL-2 and IFN-gamma production by spleen cells, further favoring the possibility that (p40)2 plays a role in the suppression of NK cell and macrophage cytotoxicity. Our results show that normal spleen cells can produce (p40)2 in response to cancer cell growth in vivo and are highly suggestive of a role for (p40)2 in the suppression of natural immunity.

Abstract
Metastatic colorectal cancer is usually progressive despite infiltration of the tumours by T lymphocytes, suggesting that these tumour-infiltrating lymphocytes (TILs) are functionally deficient. Recently, TILs from other tumours have been shown to express reduced levels of the T-cell receptor signal-transducing CD3-zeta chain. We were interested to determine whether a similar abnormality existed in TILs from human colorectal hepatic metastasis (CHM) and, if so, whether correcting the abnormality in vitro would restore anti-tumour activity and provide support for the development of immunotherapy for colorectal hepatic metastases. Twelve of 19 TILs from colorectal hepatic metastases were successfully expanded in vitro in high-dose recombinant interleukin 2 (rlL-2) and their specific anti-tumour cytolytic activity was determined. CD3-positive (CD3+) TILs were HLA-Drhigh and CD69high, suggesting that they had been activated by exposure to antigen but expressed low levels of CD25, CD71 and the nuclear proliferation antigen Ki-67. Furthermore, they showed reduced expression of CD3-zeta compared with autologous peripheral blood T cells (PBTs) and failed to proliferate in the absence of high-dose rIL-2. Expansion of TILs in rIL-2 resulted in restoration of CD3-zeta expression and the ability to lyse K562 and Daudi cells but not autologous tumour cells. The absence of autologous tumour-specific cytolytic T-cell (CTL) activity may be due to the poor immunogenicity of colorectal tumour cells, which we found expressed only low levels of MHC I antigens and CD54 and failed to express MHC II antigens or the co-stimulatory molecules CD80, CD86 or CD106. The inability of rIL-2 to generate tumour-specific CTLs despite restoration of CD3-zeta expression and the presence of an intact lytic mechanism suggests that successful immunotherapy may require the development of strategies to increase the immunogenicity of this tumour.

Abstract
We assessed the naturally occurring T-cell immune response in primary renal cell carcinoma (RCC) tumors from 12 unselected patients. A predominance of CD3+ T-cell receptor (TCR)alpha/beta+ T cells was observed in tumor-infiltrating lymphocytes (TILs), in contrast with peripheral blood lymphopenia found in some patients. Activation antigen expression on TILs revealed an imbalance in the activation status, with a significant percentage of CD69+ and HLA-DR+ and a low percentage of CD25+ and CD71+ TILs. The lymphocyte activation gene-3 (LAG-3) was detected in some TIL subpopulations and especially in one patient in whom TILs were predominantly TCR alpha/beta+CD8+DR+LAG-3+. In addition, we found that RCC TILs are polarized to a global type 1-like (Th1/Tc1) differentiation pattern (strong secretion of interferon-gamma and interleukin-2 (IL-2) following CD3/TCR crosslinking) but are under the influence of the down-modulatory cytokines IL-6 (secreted by tumor cells) and IL-10, within the tumor microenvironment. In 3 of 5 patients, clonal T-cell expansion at the tumor site was found for several Vbeta specificities, suggesting that in situ stimulation of specific clonotypes in response to potential tumor antigens is a frequent event in RCC. Furthermore, in one patient, selective intratumor amplification of a Vbeta1 subpopulation (5% of TCR alpha/beta+ cells) corresponding to 2 distinct Vbeta1-Jbeta1.6 and Vbeta1-Jbeta2.3 tumor-specific MHC class I-restricted cytotoxic T lymphocytes supports the view that discrete T-cell subsets contribute readily to in situ immunosurveillance.

Abstract
The response rate to IL-2 immunotherapy, currently used in the treatment of metastatic renal cell cancer, is limited. Based on our earlier demonstration that a combined regimen of monoclonal antibodies directed at the T cell surface protein CD3 (anti-CD3 mAbs) and IL-2 is synergistic in constraining tumor progression in a murine fibrosarcoma hepatic metastasis model, we have explored the efficacy of an anti-CD3 mAbs plus IL-2 regimen in a murine renal cell cancer model. Our studies demonstrate that a regimen of anti-CD3 mAbs plus IL-2 is superior to treatment with anti-CD3 mAbs alone or IL-2 alone in reducing the number of pulmonary metastases and in prolonging survival. Moreover, the efficacious regimen is associated with heightened intrapulmonary expression of mRNA encoding cytotoxic attack molecules (perforin, granzyme B) and immunoregulatory cytokines (IL-4, IL-10 and IFN- gamma).

Abstract
Three-color immunofluorescence flow-cytometric analysis of freshly isolated tumor-infiltrating lymphocytes (TIL) from patients with primary renal cell carcinoma (RCC) revealed a unique, not previously described TIL subset with a CD3+ CD4+ CD8alpha++ CD8beta+ phenotype. This subset represented at least 5% of CD3+ TIL in 15 of 21 patients with clear cell RCC, whereas it was not or only marginally represented in patients with papillary RCC or sarcomatoid RCC. In one-third of the patients with clear cell RCC, more than 20% of CD3+ TIL and in one patient more than half of the CD3+ TIL displayed this phenotype. The occurrence of this subset was not associated with pathological stage, tumor diameter, nuclear grade, cytogenetic abnormalities or vascular invasion in this patient cohort. When present, the CD3+ CD4+ CD8alpha++ CD8beta+ subset was detected in similar proportions in tumor tissue and tumor capsula, and it was also detected in adjacent non-tumoral renal tissue, albeit in much lower proportions. Despite strong cell surface expression of various activation markers (CD69, CD54 and HLA-DR), CD3+ CD4+ CD8alpha++ CD8beta+ cells displayed no ex vivo cytolytic activity in an anti-CD3-redirected cytotoxicity assay. In contrast with CD3+ CD4+ CD8- cells from the same tumor sample, they were markedly deficient in IL-2R alpha up-regulation following anti-CD3 triggering. The possibility that these cells represent either anergic cells or a highly specialized effector population with a discrete, as yet undescribed function is discussed.

Abstract
– Pathological criteria so far employed in the prognosis of renal cell carcinoma provide no clinically useful information. This paper emphasises the possibilities offered by histopathology today for tackling this clinical problem more effectively. Nuclear analysis, with objective and quantitative evaluation of the degree of distortion, may provide extremely useful information. The authors correctly classified 90% of the 50 cases of renal cell carcinoma considered and whose follow-up at 5 years was known.

Abstract
BACKGROUND Genital infection with certain strains of human papillomavirus (HPV) is associated with a high risk of malignant transformation, and HPV-associated cervical intraepithelial neoplasia (CIN) can become invasive cancer. Host factors are critical in regulating tumor growth, and cytokines that modulate immunologic control may be of particular importance. The type 1 cytokines interleukin 2 (IL-2) and interferon gamma (IFN gamma) are immunostimulatory and are thus capable of limiting tumor growth. The type 2 cytokines interleukin 4 (IL-4) and interleukin 10 (IL-10) are immunoinhibitory and are thus capable of stimulating tumor growth. PURPOSE We analyzed the production of cytokines by peripheral blood mononuclear cells (PBMCs) in women with CIN associated with localized or extensively spread HPV infection. METHODS Thirty women diagnosed with CIN and 10 age- and sex-matched healthy control subjects were enrolled in the study conducted at Istituto Nazionale Tumori, Milan, Italy. The following parameters were analyzed: 1) HPV infection of the cervix and other sites of the lower genital tract by colposcopic, cytologic, and histologic examinations; 2) HPV typing; 3) in vitro production of IL-2 by PBMCs in response to stimulation with soluble antigen (influenza [FLU] antigen) or to cell-associated human leukocyte antigen (HLA) alloantigen; and 4) in vitro production of the type 1 cytokines IL-2 and IFN gamma and of the type 2 cytokines IL-4 and IL-10 by PBMCs in response to mitogen stimulation. Statistical significance was determined by nonparametric tests (two-sided). RESULTS High-grade CIN associated with HPV infection was detected in all case patients, and HPV type 16 or 18 infection was detected in cervical tissue of 21 (70%) of 30 case patients. HPV infection that had spread to other sites of the lower genital tract, thus resulting in more extensive disease, was detected in 16 (53%) of the 30 individuals with CIN, whereas HPV infection was limited to the portio in 14 (47%). IL-2 production by PBMCs in response to stimulation with soluble antigen or HLA alloantigen was reduced in the group with extensive disease compared with that in the group with localized disease or with that in healthy control subjects. In contrast, IL-4 and IL-10 production in response to mitogen stimulation was elevated in the group with extensive disease compared with that in the group with localized disease or with that in healthy control subjects. The highest production of IL-4 and IL-10 was detected in patients with HPV infection that had extended beyond the genital tract. CONCLUSIONS CIN is characterized by different immunologic profiles, in which HPV infection is or is not confined to the portio. Production of cytokines that mainly enhance potentially protective cell-mediated immunity is defective in the women in whom extended HPV infection was observed. A pronounced shift from type 1 to type 2 cytokine production is associated with more extensive HPV infection. IMPLICATIONS These data reinforce the need for detailed analyses of immune dysregulation in CIN patients. They also suggest the potential usefulness of the cytokine assays for determining prognosis or deciding whether cytokine-based therapy is indicated.
