Abstract
Aims and background The purpose of the study was to investigate the IL-2/IL-2 receptor system in patients with advanced non-small-cell lung cancer (NSCLC). Patients and methods Sera from 40 subjects and 80 patients with stage III and IV NSCLC were assayed for soluble interleukin-2 receptor (sIL-2R) and interleukin-2 (IL-2) by the enzyme-linked immunosorbent assay. Circulating CD25+ cells were analyzed by flow cytoflorimetry. The data were related to clinical status by comparing the levels of slL-2R and IL-2 at diagnosis and during the treatment. Results The mean slL-2R concentrations of the NSCLC patients were significantly higher than the control population (P=0.0001); the patients with metastatic disease had significantly higher levels than those with locally advanced disease (P=0.02). No correlation was seen between circulating CD25+ cells and slL-2R levels. Disease progression was associated with an increase in slL-2R levels and a decline in IL-2; the sIL-2R/IL-2 ratio showed a gradual increase with tumor progression. Conclusions Our study demonstrates in a large series of patients that in advanced NSCLC there is an imbalance of the IL-2/IL-2 receptor system. Furthermore, circulating slL-2R levels and the sIL-2R/IL-2 ratio may be useful as markers of disease activity and treatment response, suggesting a potential prognostic value.

Abstract
An understanding of interactions within the tumor microenvironment (TME) of classic Hodgkin lymphoma (cHL) has helped pave the way to novel immunotherapies that have enabled dormant and tumor-tolerant immune cells to be reactivated. The immunosuppressive nature of the TME in cHL specifically inhibits the proliferation and activity of natural killer (NK) cells, which contributes to tumor immune-escape mechanisms. This deficiency of NK cells begins at the tumor site and progresses systemically in patients with advanced disease or adverse prognostic factors. Several facets of cHL account for this effect on NK cells. Locally, malignant Reed-Sternberg cells and cells from the TME express ligands for inhibitory receptors on NK cells, including HLA-E, HLA-G, and programmed death-ligand 1. The secretion of chemokines and cytokines, including soluble IL-2 receptor (sCD25), Transforming Growth Factor-β, IL-10, CXCL9, and CXCL10, mediates the systemic immunosuppression. This review also discusses the potential reversibility of quantitative and functional NK cell deficiencies in cHL that are likely to lead to novel treatments.

Abstract
While the cellular origin of lymphoma is often characterized by chromosomal translocations and other genetic aberrations, its growth and development into a malignant neoplasm is highly dependent upon its ability to escape natural host defenses. Neoplastic cells interact with a variety of non-malignant cells in the tumor milieu to create an immunosuppressive microenvironment. The resulting functional impairment and dysregulation of tumor-associated immune cells not only allows for passive growth of the malignancy but may even provide active growth signals upon which the tumor subsequently becomes dependent. In the past decade, the success of immune checkpoint blockade and adoptive cell transfer for relapsed or refractory lymphomas has validated immunotherapy as a possible treatment cornerstone. Here, we review the mechanisms by which lymphomas have been found to evade and even reprogram the immune system, including alterations in surface molecules, recruitment of immunosuppressive subpopulations, and secretion of anti-inflammatory factors. A fundamental understanding of the immune evasion strategies utilized by lymphomas may lead to better prognostic markers and guide the development of targeted interventions that are both safer and more effective than current standards of care.

Prog Neuropsychopharmacol Biol Psychiatry 2012; 37:106-10.

Abstract
OBJECTIVE Previous studies have indicated that the immune may be involved in the pathogenesis of tardive dyskinesia (TD). Some genetic polymorphisms in the human leukocyte antigen (HLA) I and II regions have been associated with TD, and the tumor necrosis factor-α (TNF-α) gene is located in the HLA III region. TNF-α levels in the striatum significantly increased in haloperidol-induced TD in rats. The TNF-α gene -308A/G single nucleotide polymorphism (SNP) has been shown to directly influence TNF-α expression. The genetic association between the TNF-α gene -308A/G SNP and TD is unclear. The present study investigated whether this variation is associated with clinical phenotypes and TD in schizophrenia in a genetically homogeneous northern Chinese Han population. METHODS We genotyped the TNF-α gene -308A/G SNP in patients with schizophrenia with TD (n=350) and without TD (n=410). The Abnormal Involuntary Movement Scale (AIMS) and Positive and Negative Syndrome Scale (PANSS) were used to assess the severity of TD and psychopathology of schizophrenia, respectively. RESULTS The allele and genotype frequencies did not significantly differ between patients with schizophrenia with and without TD (p>0.05). No significant difference was found in the total AIMS score between the genotypes (p>0.05). However, the PANSS negative symptom subscore was associated with risk for TD (p=0.004), and a significant difference was found in total AIMS score between the genotypes in TD patients (p=0.013). CONCLUSION The TNF-α gene -308A/G polymorphism does not appear to play a major role in the susceptibility to TD in patients with schizophrenia in a northern Chinese Han population. However this polymorphism may play a role in the TD severity.

Abstract
The clinical and pathologic features of classical Hodgkin lymphoma (cHL) reflect an abnormal immune response that is thought to be due to the elaboration of a variety of cytokines by the malignant Reed-Sternberg (RS) cells or surrounding tissues. The majority of cHL cases are characterized by expression of tumor necrosis factor receptor (TNFR) family members and their ligands, as well as an unbalanced production of Th2 cytokines and chemokines. Activation of TNFR members results in constitutive activation of nuclear factor-kappa B (NF-kappa B), a transcription factor important for the in vitro and in vivo growth of RS cell lines. The expression of Th2 cytokines and chemokines leads to the reactive infiltrate of eosinophils, Th2 cells, and fibroblasts characteristic of cHL, and can also contribute to a local suppression of Th1 cell-mediated cellular immune response. Another particularly important growth and survival factor for RS cell lines is the Th2 cytokine interleukin 13, which is also commonly expressed by primary RS cells. In approximately 40% of cHL cases, the presence of Epstein-Barr virus influences the Th1/Th2 balance toward the production of Th1 cytokines and chemokines, but this shift is apparently insufficient for the stimulation of an effective antitumor cell-mediated immune response. This review summarizes the current literature on cytokine expression by and activity on RS cell lines and primary cHL tissues, examines cytokine signaling pathways in RS cells, and discusses the role that cytokines play in the specific clinical and pathologic features of cHL.

Abstract
An increasing body of evidence suggests a role for the immune system in the pathogenesis of schizophrenia. The information concerning the effects of antipsychotics on cytokine profiles are limited and often controversial in particular regarding novel antipsychotics. The authors first investigated the production of various cytokines [interleukin (IL)-2, IL-4, IL-10, interferon (INF)-gamma] in drug-free (n = 12) and drug-naive (n = 3) schizophrenic patients and in healthy controls (n = 33) and then the modifications of cytokines values during a 3-month period of treatment with risperidone. In the baseline condition, the production of IL-2 and INF-gamma was significantly higher (P = .023 and .026, respectively) in patients than in controls. In the same patients, the use of risperidone was associated with augmented IL-10 (a suppressor of Type I cytokines) and decreased INF-gamma production. This modification suggests that clinical improvement is associated with a reduction in the inflammatory-like situation present in not currently treated schizophrenic patients.

Abstract
There are some reports describing concurrent changes in lymphocytic and monocytic activities in schizophrenia. In this study we investigated T cell activity in schizophrenic patients by measuring the release of interleukin-2 (IL-2) and soluble interleukin-2 receptor (sIL-2R) by T cells and the percentages of CD4+ and CD8+ cells in blood. The release of IL-2 and sIL-2R by T cells was evaluated in dilute whole blood after in-vitro stimulation with phytohemagglutinin. IL-2 levels and the percentage of CD4-cells tended to decrease and sIL-2R levels decreased significantly in schizophrenic patients. Haloperidol and perazine significantly decreased IL-2 levels and increased sIL-2R levels and the percentage CD4-cells. IL-2 and sIL-2R levels were lower in patients with a predominance of positive symptoms. The neuroleptic-induced increase in sIL-2R levels was higher in patients with a predominance of positive symptoms compared with those in whom both positive and negative symptoms were severe. The study has shown that T-cell activity is reduced in schizophrenia and that neuroleptics may have immunomodulatory properties.

Abstract
The consequences of high serum concentrations of the interleukin (IL)-2 receptor alpha chain (sIL-2Ralpha) in several diseases are poorly understood. The objective of this study was to determine the form of sIL-2Ralpha in burn patients and its biological role. sIL-2Ralpha was measured in 18 severely burned individuals who received nutritional support with a normal or low fat content. sIL-2Ralpha was elevated throughout the study and it was notably lower in patients fed a low fat diet. Serum IL-6 and sIL-2Ralpha significantly correlated (r = 0.74, p < 0.05) in burn patients. The presence of sIL-2Ralpha was associated with a decrease in DR molecules in the CD2(-) and CD11b(+) cells of these patients. Western blot analysis of serum protein with N-terminal or C-terminal specific antibodies indicated that sIL-2Ralpha represents the extracellular domain of this molecule. Patient serum inhibited specifically murine, but not human IL-2-dependent T-cell proliferation. To determine the significance of sIL-2Ralpha, recombinant sIL-2Ralpha was used in different cellular model involving IL-2. sIL-2Ralpha inhibited natural killer cell activity by 50% in the presence of IL-2. The basal proliferation of peripheral blood mononuclear cells was inhibited by sIL-2Ralpha, but phytohemagglutinin-induced proliferation was unaffected by this form of receptor. Interferon (INF)-gamma production induced by OKT-3 on peripheral blood mononuclear cells was not altered by sIL-2Ralpha, but IL-2 induced increase in INF-gamma production was suppressed. The decreasing production of INF-gamma in the presence of IL-4 was significantly increased in the presence of sIL-2Ralpha in media. These results show that the large amount of sIL2-Ralpha circulating in burn patients is related to the inflammatory response. The amount of dietary fat modulates sIL2Ralpha concentration in burn patients, confirming the beneficial effect of low fat administration after burn trauma. Inhibition of T-cell activation in burn patients is not directly related to sIL-2Ralpha, although the presence of sIL-2Ralpha in serum can inhibit some IL-2 mediated response, such as the emergence of TH1 and TH2 cells.

Abstract
1. Parallel to the current rapid development of new immunological methods, immune mechanisms are gaining more importance for our understanding of psychiatric disorders. The purpose of this article is to review basic and clinical investigations that elucidate the relationship between the CNS and the immune system. 2. The topical literature dealing with the interactions of immune system, neurotransmitters, psychological processes, and psychiatric disorders, especially in relation to cytokines, is reviewed. 3. An activation of the immune system in schizophrenia and depressive disorders has repeatedly been described. Cytokines, actively transported into the CNS, play a key role in this immune activation. It was recently observed that cytokines activate astrocytes and microglia cells, which in turn produce cytokines by a feedback mechanism. Moreover, they strongly influence the dopaminergic, noradrenergic, and serotonergic neurotransmission. 4. There are indications that the cascade of cytokines can be activated by neuronal processes. These findings close a theoretical gap between stress and its influence on immunity. Psychomotor, sickness behavior and sleep are related to IL-1; disturbances of memory and cognitive impairment are to IL-2, in part also to TNF-alpha. The hypersecretion of IL-2 is assumed to have a prominent influence on schizophrenia, and IL-6, on depressive disorders. 5. Although single cytokines most likely do not have a specificity for certain psychiatric disorders, a characteristic pattern of cytokine actions in the CNS, including influences of the cytokines on the blood-brain barrier, seems to play a role in psychiatric disorders. This may have therapeutic implications for the future.

Abstract
The cytokines interleukin-2 (IL-2) and interleukin-6 (IL-6) increase during immune activation, they are released from activated astrocytes and microglial cells in the central nervous system (CNS), and they are able to enhance the catecholaminergic neurotransmission. This study focused on the soluble receptors of IL-2 and IL-6 (sIL-2R, sIL-6R) as a part of the regulation system of IL-2 and IL-6. We studied serum levels of sIL-2R in 30 schizophrenic patients not under neuroleptic medication during an acute exacerbation of the disease and reexamined these patients under neuroleptic treatment after clinical improvement. The sIL-6R levels of 39 schizophrenic patients were estimated under the same conditions. The results were compared with the levels of sIL-2R and sIL-6R in 42 healthy controls. No difference was found between the schizophrenic patients before neuroleptic treatment and the healthy controls. During neuroleptic treatment, however, there was a significant increase of sIL-2R levels and a significant decrease of the sIL-6R levels between the pre- and post-conditions. In comparison with healthy controls, the treatment group also showed increased sIL-2R levels and decreased sIL-6R levels. These results suggest that treatment with neuroleptics is associated with increased sIL-2R and decreased sIL-6R. Since sIL-2R bind and inactivate IL-2, whereas sIL-6R form an active complex with IL-6, the increase of sIL-2R and the decrease of sIL-6R together may reflect a functional down regulation of these activating cytokines. This suggests that neuroleptic therapy has a differentiated immunomodulatory effect.

Abstract
BACKGROUND The serum levels of soluble interleukin-2 receptor (S-sIL-2R) have been shown to be related to clinical outcome in Hodgkin's disease (HD). sIL-2R may be involved in or aggravate the immunodeficiency seen in HD patients. This immunodeficiency is most pronounced in elderly patients. PATIENTS AND METHODS S-sIL-2R was determined in 127 untreated patients with HD, diagnosed between 1979 and 1991, in order to evaluate its prognostic value in relation to other known prognostic variables with special emphasis on the elderly. RESULTS S-sIL-2R levels were significantly higher in patients with stages III-IV and with B-symptoms (p < 0.001) but not in patients over 60 years of age. In multivariate analyses, S-sIL-2R, stage and S-orosomucoid were the most important prognostic factors in all patients and S-sIL-2R was the only prognostic factor in patients over the age of 60. CONCLUSIONS The results indicate a future role for estimation of S-sIL-2R in the management of patients with HD.

Abstract
T helper cell (TH) function, as assessed by interleukin-2 (IL-2) production and [3H]thymidine incorporation, was studied in 47 newly diagnosed untreated patients with Hodgkin's disease (HD) and 34 healthy controls. Three different stimuli were used to stimulate in vitro peripheral blood mononuclear cells (PBMC): influenza A vaccine (FLU), HLA alloantigens (ALLO) and phytohaemagglutinin (PHA). Four different patterns of TH function were observed in HD patients: (1) IL-2 production in response to all of the stimuli (40%); (2) IL-2 production in response to ALLO and PHA but not to FLU (26%); (3) IL-2 production in response to PHA alone (19%); and (4) failure to respond by IL-2 production to any of the three of the stimuli (15%). Thus, defective in vitro TH function was detected in the majority of these patients (60%). Defective TH function was observed in none of the 34 controls. Severely compromised TH function (patterns 3 and 4) tended to be associated with more advanced clinical presentation and more compromised haematological parameters (P < 0.05). The IL-2 production assay was more sensitive than the proliferative assay as only 30% of the HD patients failed to proliferate in response to FLU, and none failed to proliferate in response to either ALLO or PHA; this assay can detect subtle, multiple patterns of immune dysregulation in untreated HD patients. Our results suggest that HD is associated with a fundamental dysregulation in TH function, illustrate the complexity of such dysregulation, and raise the possibility that HD progression will be associated with a type-1-type-2 switch in immunoregulatory cytokine production.
