Abstract
BACKGROUND Head and neck squamous cell carcinomas are associated with systemic inflammation (SI). We evaluated whether DNA methylation-derived SI (mdSI) indices are associated with oropharyngeal cancer risk and survival. METHODS Ninety-four oropharyngeal squamous cell carcinoma (OPSCC) cases and 57 controls with DNA methylation data were included. Logistic regression analysis and survival analysis were performed to test the association of mdSI indices with OPSCC risk and survival. RESULTS Higher methylation-derived neutrophil-to-lymphocyte ratio (mdNLR) was associated with increased risk of OPSCC (OR = 1.21, 95%CI: 1.11-1.40) while no association was found with methylation-derived lymphocyte-to-monocyte ratio (mdLMR). For 5-year overall survival, higher mdLMR was significantly associated with decreased risk of death (HR = 0.25, 95%CI: 0.10-0.64) while the converse was observed for mdNLR (HR = 2.48, 95%CI: 1.04-5.92). CONCLUSION We observed an association between mdSI indices and OPSCC risk and 5-year overall survival. It is possible to use mdLMR as an independent prognostic factor for OPSCC.

Abstract
Septic syndromes remain a major although largely under-recognized health care problem and represent the first cause of mortality in intensive care units. While sepsis has, for long, been solely described as inducing a tremendous systemic inflammatory response, novel findings indicate that sepsis indeed initiates a more complex immunologic response that varies over time, with the concomitant occurrence of both pro- and anti-inflammatory mechanisms. As a resultant, after a short proinflammatory phase, septic patients enter a stage of protracted immunosuppression. This is illustrated in those patients by reactivation of dormant viruses (CMV or HSV) or infections due to pathogens, including fungi, which are normally pathogenic solely in immunocompromised hosts. Although mechanisms are not totally understood, these alterations might be directly responsible for worsening outcome in patients who survived initial resuscitation as nearly all immune functions are deeply compromised. Indeed, the magnitude and persistence over time of these dysfunctions have been associated with increased mortality and health-care associated infection rate. Consequently, new promising therapeutic avenues are currently emerging from those recent findings such as adjunctive immunostimulation (IFN-γ, GM-CSF, IL-7, anti-PD1/L1 antibodies) for the most immunosuppressed patients. Nevertheless, as there is no clinical sign of immune dysfunctions, the prerequisite for such therapeutic intervention relies on our capacity in identifying the patients who could benefit from immunostimulation. To date, the most robust biomarkers of sepsis-induced immunosuppression are measured by flow cytometry. Of them, the decreased expression of monocyte HLA-DR appears as a "gold standard." This review reports on the mechanisms sustaining sepsis-induced immunosuppression and its related biomarkers measurable by flow cytometry. The objective is to integrate the most recent facts in an up-to-date account of clinical results, flow cytometry aspects as well as issues in results standardization for multicenter studies. © 2015 International Clinical Cytometry Society.

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
BACKGROUND Patients with advanced stages of head and neck cancer are often characterized by malnutrition and by an impaired immune system. Because some of the suppressed immune parameters were shown to be of prognostic importance in trauma and sepsis, we investigated whether these would also correlate with survival in head and neck cancer. METHODS Severely malnourished head and neck cancer patients undergoing ablative and reconstructive surgery were followed prospectively and their perioperative immune parameters were related to long-term survival. RESULTS Forty-nine patients with a preoperative weight loss of more than 10% were followed up for a period of at least 16 months after surgery. Analyses of variance revealed that preoperative human leukocyte antigen-DR (HLA-DR) expression on monocytes and endotoxin-induced production of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were different between patients who survived and patients who died. Proportional hazards identified a weight loss of more than 12%, the presence of coexistent disease, and an HLA-DR expression on monocytes below the cutoff points (mean fluorescence index < 15, peak channel index < 9) to be of significant influence on survival. CONCLUSIONS In addition to known prognostic parameters such as tumor stage, coexistent disease, and weight loss, the immune parameters HLA-DR expression on monocytes and endotoxin-induced cytokine production may carry prognostic value in cancer patients. Immunomodulating therapies leading to improvement of these parameters might in the future lead to increased options for treatment.

Abstract
Malnutrition is reported to occur in approximately 30% of head and neck cancer patients. Also, impaired immunocompetence is described as a common phenomenon in this patient group. The purpose of this study was to assess the possible relationship between malnutrition and some prognostically important immune parameters in head and neck cancer patients. Thirty-two malnourished (recent weight loss >/= 10%) and 34 well-nourished patients undergoing curative treatment for advanced head and neck cancer were studied prospectively, and six parameters of their immune status (leucocytes, lymphocytes, lymphocyte phenotyping, monocytes, HLA-DR expression on monocytes and serum interleukin-10) were determined on the day of panendoscopy. Reference values for monocytes, HLA-DR expression and interleukin-10 were obtained from 43 healthy controls. Although the number of monocytes was elevated in both patient groups, the HLA-DR expression on these monocytes was significantly lower in the malnourished than in the well-nourished and control groups. Tumor stage, tumor localization, recurrence after initial radiotherapy, age and gender were not correlated to HLA-DR expression. No relationships emerged between nutritional status and lymphocyte subsets. Malnourished head and neck cancer patients show a significantly lower HLA-DR expression on monocytes than well-nourished ones and healthy controls. According to the literature this would imply an increased risk for postoperative complications. Indeed, postoperative complications occur more frequently in malnourished than in well-nourished patients.

Abstract
T-lymphocyte cell function was studied in vitro in peripheral blood mononuclear cells (PBMC) from 61 male patients with head and neck squamous cell carcinomas compared to 46 control patients. Patients older than 80 years or with reduced tumor-related performance status as measured by Karnofsky score less than 75 were excluded. In contrast to previous similar studies, control subjects ensured a minimum stress load by sampling all patients on the day of either diagnostic or therapeutic surgery. PBMC were separated by density-gradient centrifugation and subsequently cultured with autologous sera in vitro. The mitogen concanavalin A (Con A), which stimulates all T-cell clones, was employed. Findings showed that increased Con A stimulation and PBMC proliferation occurred with PBMC from cancer patients compared to that from control patients. In contrast, no differences could be detected with respect to the stimulated supernatant level of interleukin-2, interleukin-4 or interferon-gamma between the groups. These results suggest that T-lymphocytes from PBMC are generally affected by neoplastic disease through either a supporting cell or serum factor.

Abstract
Although studies indicate that alveolar macrophages participate in host defense against Pneumocystis carinii, their role in organism degradation and clearance from the lung has not yet been established. We, therefore, quantified the uptake and degradation of 35S-labeled P. carinii by cultured macrophages, demonstrating significant degradation of P. carinii over 6 h. We further evaluated the role of macrophages in elimination of P. carinii from the living host. Rats received either intratracheal PBS, liposomal PBS (L-PBS), or liposomal dichloromethylene diphosphonate (L-Cl2MDP), a preparation which leads to selective depletion of macrophages. Over 72 h, L-Cl2MDP-treated animals had loss of > 85% of their alveolar macrophages. In contrast, L-PBS-treated rats had cellular differentials identical to rats receiving PBS. Macrophage-depleted rats and controls were next inoculated with P. carinii and organism clearance was determined after 24 h. P. carinii elimination was evaluated with both cyst counts and an ELISA directed against glycoprotein A (gpA), the major antigen of P. carinii. Both assays indicated that macrophage-depleted rats had substantial inpairment of P. carinii clearance compared to L-PBS- or PBS-treated rats. These data provide the first direct evidence that macrophages mediate elimination of P. carinii from the living host.

Abstract
The interactions between the tumor and its host are complex, and many aspects of the immune system appear to be adversely affected directly or indirectly by the presence of the tumor. Virtually all of the processes involved in immune induction and action have been implicated in the observed deficient response in tumor-bearing patients. Improved understanding and molecular analysis of the mechanisms underlying the escape of tumors from immune surveillance may lead to the development of novel strategies for the prevention of T-cell immunosuppression in cancer patients, the development of novel immunotherapeutic strategies, and potentially prevention of tumor progression or development.

Abstract
Oncologic patients constitute a population whose susceptibility to infections is conditioned by a broad variety of factors. Advances in antineoplastic treatments have resulted in significant prevalence of severe immunosuppression among such patients. Although impairment of more than one distinct effector limb of host defenses occurs in each patient, infections can usually be attributed to a particular deficiency. Major risk factors for infections include granulocytopenia and defects of cell-mediated immunity or of humoral immunity. In the extreme situation of allogeneic bone marrow transplantation, the multitude and the timing of infections can be explained by significant dysfunction of all types of specific immune deficiencies. Treatment of bacterial infections has become more effective with the advent of broad-spectrum antibiotics; however, the dreadful emergence of polyresistant strains may be a serious problem in the near future. Prevention strategies have reduced the risk posed by important pathogens such as CMV or PCP, whereas we still lack reliable treatment against invasive mycoses. The advent of growth factors is a useful adjunct in our armamentarium; in addition to shortening the neutropenic periods after chemotherapy, they may restore qualitative defects of phagocytes. Their exact usefulness and role in managing infections remains to be defined.

Abstract
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) produces immunosuppressive low-molecular-mass factors (LMMFs) responsible for defects in the cell-mediated immune system. These defects include impaired monocyte chemotaxis and an impaired capability of dendritic cells (DC) to form cellular clusters. It has been shown previously that the immunomodulating drug thymostimulin (TP1) restores these defects in vitro. METHODS An immunohistochemical study was performed on tumors of 18 patients with HNSCC who had preoperatively been treated with TP1 in one of three dosages (0.5 mg/kg, 1.0 mg/kg, 2.0 mg/kg body weight). Additionally, tumors of 4 patients who had been treated with a placebo and 12 patients who had not received any preoperative treatment were studied. A relative surface area of infiltration, meaning the percentage of stromal or epithelial tissue covered by infiltrating cells in histological sections, was calculated using an image analysis system (VIDAS RT) for CD3+ T-cells, CD14+/CD68+ monocytes/macrophages and L25+/CD1a+ dendritic cells for each tumor. RESULTS A highly significant, denser T-cell infiltration into the stromal tissue area of tumors of patients who had been treated with TP1 when compared with tumors of non-TP1-treated patients was observed for all three dosages. None of the other tumor-infiltrating cell types was affected by TP1. In addition, a correlation was found between the tumor T-cell infiltration and capability of DCs in the peripheral blood to form clusters with T-cells. No correlation existed between CD3+ T-cell numbers in peripheral blood and T-cell infiltration into the tumor; nor were monocyte chemotactic functions in peripheral blood correlated with tumor infiltration by monocytes or monocyte-derived macrophages and DCs. CONCLUSIONS Preoperative treatment of HNSCC patients with TP1 appears to strongly enhance tumor--T-cell infiltration. The number of tumor-infiltrating DCs was not affected by TP1, but a positive correlation between tumor--T-cell infiltration and DC clustering capability suggests that the functional status of DCs is important in improved cell-mediated immunity.

Abstract
Decreased skin reactions using five kinds of recall antigens correlate d with the stage of colorectal cancer. Immunosuppressive factors in the serum (IS index) increased with the progression of the stage in cancer patients, but interleukin (IL)-I and IL-2 production in peripheral mononuclear cells (PBMC) did not correlate with the advance of the disease. In patients with low immunosuppressive factors, the score of skin reactions was significantly higher than that in patients with high immunosuppressive factors. Increased serum immunosuppressive factors seem to reduce skin reactions in the patients. Furthermore, significant difference in skin reaction score was observed between patients with high IL-1 production of PBMC and patients with low IL-1 production of PBMC. These results suggest that skin reaction might be controlled by serum immunosuppressive factors and IL-1 production of PBMC, and that the score of skin reaction using multirecall antigens is a useful parameter to learn the host immunity in colorectal cancer.

Abstract
A study was undertaken to help us reach a better understanding of the tumor-infiltrating pattern of lymphoid cells and in particular of monocyte-derived cells, namely the CD68+, acid-phosphatase-expressing scavenger macrophages and the MHC-class-II- and S100-antigen-presenting dendritic cells in head and neck squamous-cell carcinoma. In the stroma of the tumors distinctive small fields of lymphocytes were found, the T cell areas of these fields being intermingled with dendritic cells. Intra-epithelial dendritic cell infiltration was low. The infiltrative pattern of macrophages was similar to patterns described in earlier studies with substantial stromal invasion and inconsistent intra-epithelial invasion, but small granuloma-like structures of CD68+ macrophage-like cells, found in the stroma of tumors, have not been reported before. The histochemical localization of the tumor-infiltrated dendritic cells and macrophages supports the view that the former cells are involved in the sensitization to tumor antigens, whereas the latter cells are involved in tumor cytotoxicity/scavenging of tumor cell debris. Although it has been shown in the past that transmembranal (TM) factors (p15E-like factors) present in the serum and tumor of patients with cancer of the head and neck have suppressive effects on monocyte/macrophage/dendritic cell function, a relationship between the intensity of epithelial staining for TM factors and the infiltrative pattern of monocytes/macrophages/dendritic cells could not be demonstrated.

Abstract
When used as a polyclonal activator of blood immunocompetent cells in the squirrel monkey, pokeweed mitogen (PWM) failed to induce lymphoproliferation unless either autologous or human serum was added to the culture medium, instead of a serum assumed to be deprived of Ig such as foetal bovine serum. We thus attempted to delineate activation processes initiated by PWM and which required both monocytes and native Ig molecules. For instance, the physical presence of live monocytes within lymphocyte suspensions vs. paraformaldehyde-fixed monocytes or products of monocytic origin was an absolute prerequisite for inducing squirrel monkey lymphocytes to proliferate in the presence of PWM. In addition, a combination of monocytes and native Ig were further shown to induce lymphocytes to proliferate in the presence of PWM. We therefore questioned whether Fc gamma R on the surface of monocytes vs. Fc gamma R expressed by other cells were involved in the initiation of PWM-driven lymphoproliferation. PWM may represent a useful tool for studies of Fc gamma R-mediated immunological processes.

Abstract
We report here on functional aspects of squirrel monkey T cells isolated either from peripheral blood mononuclear cells or in the presence of accessory cells or accessory-cell-secreted cytokines. The T-cell response triggered by polyclonal activators was measured through proliferation, T-cell growth factor production and transient expression of receptors to growth factors. We also sought to delineate mechanisms by which antimitogenic molecules might prevent lymphocytes from being able to express "activation antigens" and/or from proliferating. Under these conditions, we mainly explored the inducible IL2/IL2R pathway and phenomena occurring in lymphocyte "non-activation" in terms of early and late cellular events; indeed, defects in the IL2/IL2R pathway represent one of the dysregulation events presumed to occur during the acute phase of human malaria, disease for which. Saimiri monkeys have been selected as experimental hosts.

Peripheral blood monocytes from non-Hodgkin's lymphoma (NHL) patients were assessed for the monocyte functions with respect to their ability to secrete interleukin-1 and tumour necrosis factor (TNF) and their cytotoxic potential to tumour target WEHI 164 clone 13. Our results indicate comparable levels of interleukin-1 and TNF production by NHL patients. The cytotoxic potential by monocytes was also not depressed in these patients. The data obtained suggest normal monocyte functions in NHL patients.

Abstract
Interleukin-1 (IL-1) is a cytokine with multiple biologic activities. Since its first description in 1972, significant work has been done, leading to an understanding of the biology of IL-1, which plays a central role in many important functions of the immune system. The biologic activities of IL-1 make it an attractive factor for use in clinical oncology, both as an antitumor agent and for the hematologic recovery of cancer patients receiving other forms of therapy. In this review the biologic effects of IL-1 are summarized. The possible involvement of IL-1 in the pathogenesis of some diseases is reviewed. Future prospects for the use of IL-1 in the treatment of malignancies are discussed.

Abstract
Mice bearing progressively growing syngeneic methylcholanthrene-induced sarcomas are immunologically hyporeactive. However, both basal (steady-state) and bacterial lipopolysaccharide (LPS)-induced synthesis of mRNA for interleukin-1 (IL-1) in peritoneal exudate cells (PEC) or spleen cells were comparable in control and tumour-bearing animals. Furthermore, the production of IL-1 by PEC stimulated with LPS in the presence of indomethacin was same in control and tumour-bearing mice. The results thus demonstrate that LPS-stimulated cells from animals bearing progressively growing syngeneic sarcomas synthesise the same quantities of mRNA for IL-1 and produce comparable amounts of IL-1 as do cells from normal animals, in spite of the profound immunological hyporeactivity of the former.

Abstract
Peripheral blood monocytes and draining lymph node macrophages from patients with squamous cell carcinoma of the oral cavity, monocytes from patients with oral leukoplakia and those from healthy donors were assessed for FcR. HLA-DR expression and interleukin-1 (IL-1) production after activation with LPS or IFN gamma. Monocyte cytotoxicity was also tested after activation with LPS, IFN gamma, IL-2 singly, or in combinations at suboptimal concentrations. The results showed that the percentage of activated monocytes expressing FcR was significantly low in untreated oral cancer patients, however, the proportion of HLA-DR positive cells was normal. The unstimulated monocytes from oral cancer patients showed spontaneous generation of IL-1. Upon activation, few patients could produce IL-1 to normal levels. The unstimulated monocytes from untreated patients and treated patients with recurrence also exhibit significantly higher tumoricidal activity. Treatment of monocytes with combinations of two modulators (IFN gamma, LPS and IL-2) induced significantly higher cytotoxicity.

Abstract
Characterization and functional aspects of squirrel monkey peripheral blood mononuclear cells (PBMC), and mainly T cells, are described in the present paper; this should enable the study of cellular immune responses in an experimental model for malaria. PBMC were obtained from Ficoll-Hypaque gradient separation and fractionated into T cells and non-T cells by means of E-rosetting techniques and adherence to plastic dishes. PBMC subset phenotypes were characterized by means of monoclonal antibodies (mAb) directed against human leukocyte differentiation antigens (Ag), fluoresceinated lectins, anti-surface Ig (squirrel-monkey-specific) antibodies (Ab) and latex bead ingestion assays. PBMC functions were assayed through lymphoblastic transformation tests (LTT) in the presence of either numerous mitogenic, comitogenic and anti-mitogenic lectins or anti-human leukocyte differentiation Ag mAb. We sought to standardize reference values for lymphocyte phenotypes and functions in normal squirrel monkeys (prior to experimental infection). We also present evidence that splenectomy (generally rendered necessary for experimental human malaria infection) performed six months prior to the present investigation did not modify PBMC numbers and functions in the tested animals.
