DOWN-REGULATION OF FIBRINOGEN BIOSYNTHESIS BY IL-4, IL-10 AND IL-13

High levels of fibrinogen are recognized as an important vascular risk factor; however, it is not known if the increase of plasma fibrinogen is directly responsible for this risk, or is only a marker of vascular inflammation. To support this second hypothesis, Oncostatin M (OSM) is a potent stimulator of fibrinogen biosynthesis and induces smooth muscle cell proliferation. In the same way, we analysed whether interleukin-4 (IL-4), interleukin-10 (IL-10) or interleukin-13 (IL-13), which protect vessel walls from monocytes injuries leading to atherosclerosis, could influence fibrinogen biosynthesis. The two levels of regulation of fibrinogen biosynthesis were tested: firstly, the direct effect of these cytokines on fibrinogen production by the hepatoma cell line Hep G2, and secondly their effect on the secretion of hepatocyte stimulating factor (HSF) activity in the supernatant of lipopolysaccharide (LPS)-activated monocytes. IL-4 and IL-13 added to Hep G2 cells down-regulated both the increase of fibrinogen secretion induced by IL-6 and fibrinogen mRNA levels, this effect being more pronounced when Hep G2 were preincubated with the two cytokines before IL-6 addition. The effect of IL-10 was evidenced only on mRNA expression. IL-10 and IL-13 dose-dependently decrease HSF activity secreted by LPS-activated monocytes, whereas IL-4 had no effect. However, the three cytokines decreased HSF activity when monocytes were incubated with the cytokines before LPS activation. The effects of these cytokines on HSF activity are related to variations of IL-6 and OSM secretion. Our data strengthen the hypothesis that the fibrinogen level is a marker of vascular disease, since cytokines which have a protective vascular effect down-regulate fibrinogen production.     

Serum IL-4, IL-10 and IL-6 levels in inflammatory arthritis

As the available in vitro and in vivo data suggest that interleukin (IL)-4 and IL-10 have immunosuppressive activity, our hypothesis was that serum IL-4 and IL-10 levels would correlate inversely with parameters of inflammation in patients with inflammatory arthritis. IL-4 was detected in the serum of 12 out of 140 patients with rheumatoid arthritis (RA), which was increased compared to the proportion found with patients with osteoarthritis (OA; P< 0.02). In addition, IL-4 was detected in the serum of 2 of 19 patients with systemic lupus erythematosus (SLE), 2 of 24 patients with psoriatic arthritis and 1 of 5 patients with Behçet's syndrome. No IL-4 was detected in patients with the following conditions: OA (58 patients), gout (17 patients), ankylosing spondylitis (6 patients), Reiter's syndrome (6 patients), polymyalgia rheumatica (6 patients), temporal arteritis (5 patients) and scleroderma (3 patients). No IL-10 was detected in any of the sera tested. We discuss the possible relevance of these results to the regulation of the immune response evident in inflammatory arthritis.

Expression of IL-23 and IL-17 and effect of IL-23 on IL-17 production in ankylosing spondylitis

The objective of this study was to investigate the expression of IL-23 and IL-17 and the influence of IL-23 on IL-17 production in ankylosing spondylitis (AS) patients. IL-23 and IL-17 levels in the serum and supernatants of cultured peripheral blood mononuclear cells (PBMCs) were determined by ELISA. IL-23p19 mRNA expression in PBMCs were analyzed using RT-PCR. The patients with AS at active stage showed elevated levels of IL-23 and IL-17 in the serum and supernatants of cultured PBMCs. A higher expression of IL-23p19 mRNA in PBMCs of AS patients was also observed. A significantly enhanced production of IL-17 in the supernatants of cultured PBMCs was found in the presence of recombinant IL-23 and this effect was more significant in patients with AS. The results suggest that IL-23 and IL-17 may play critical roles in the pathogenesis of AS and IL-23-stimulated production of IL-17 by PBMCs may be responsible for the development of AS.     

IL-12及IL-10在桥本甲状腺炎发病机制中作用的研究进展

桥本甲状腺炎是一种常见的慢性自身免疫性疾病,表现为辅助性T细胞(Th)1占优势。 Th1类细胞因子白细胞介素(IL)-12表达增加,在该病的诱发及慢性迁延中起重要作用,Th2类细胞因子IL-10表达的下调也与该病有关,且随病情变化二者表达水平有所不同。因此,这些细胞因子可作为病情变化的监测指标,并且可通过调节细胞因子的表达水平从而使失衡的Th1／Th2细胞趋于平衡。这可能为桥本甲状腺炎的治疗开拓一条新途径。     

A complex of the IL-1 homologue IL-1F7b and IL-18-binding protein reduces IL-18 activity

IL-1F7 was discovered in expressed sequence tag databases as a member of the increasing family of proteins sharing sequence homology to IL-1alpha/beta, IL-1Ra, and IL-18. In the present study using immunohistochemical staining, IL-1F7 was localized in human peripheral monocytic cells, suggesting its role in immune regulation. Recombinant human IL-1F7b was shown to bind to the IL-18Ralpha but without IL-18 agonistic or antagonistic function. Using chemical cross-linking, we observed that, unlike IL-18, IL-1F7b fails to recruit the IL-18Rbeta chain to form a functionally active, ternary complex with the IL-18Ralpha chain. IL-1F7b shares two conserved amino acids with IL-18 (Glu-35 and Lys-124), which participate in the interaction of IL-18 with the IL-18Ralpha chain as well as the IL-18-binding protein (IL-18BP), a secreted protein that neutralizes IL-18 activity. In testing whether IL-1F7b interacts with IL-18BP, we unexpectedly observed that IL-1F7b enhanced the ability of IL-18BP to inhibit IL-18-induced IFNgamma by 25-30% in a human natural killer cell line. This effect was observed primarily at limiting concentrations of IL-18BP (3.12-12.5 ng/ml) and at a 50- to 100-fold molar excess of IL-1F7b. Similar results were obtained by using isolated human peripheral blood mononuclear cells. To study the molecular basis of this effect we performed binding studies of IL-1F7b and IL-18BP. After cross-linking, a high molecular weight complex consisting of IL-1F7b and IL-18BP was observed on SDS/PAGE. We propose that after binding to IL-18BP, IL-1F7b forms a complex with IL-18Rbeta, depriving the beta-chain of forming a functional receptor complex with IL-18Ralpha and thus inhibiting IL-18 activity.     

Prognostic values of IL-6, IL-8, and IL-10 in acute pancreatitis

GOALS: The prognostic importance of interleukin-6 (IL-6), IL-8, and IL-10 in the prediction of acute pancreatitis severity. BACKGROUND: Early assessment of severity in acute pancreatitis could help the patients who are at risk of developing complications. Unfortunately, the used prognostic scoring systems generally are only moderately accurate in assessing disease severity. STUDY: We studied 117 consecutive patients with a diagnosis of acute pancreatitis admitted to our hospital during the past 2 years. Laboratory parameters and cytokines were analyzed from serum taken routinely on admission. Severity criteria were noted for each patient using Ranson, Glasgow, and APACHE II scoring systems. Local and systemic complications, developed during a follow-up period, were classified by Atlanta criteria. RESULTS: IL-6 was the only parameter that statistically significantly predicted complicated acute pancreatitis (P<0.05). IL-8 and IL-10 and the 3 prognostic scoring systems used did not properly assess complicated versus noncomplicated acute pancreatitis. CONCLUSIONS: Our prospective study supported the potential importance of IL-6 in the early assessment of complicated acute pancreatitis, but also suggested that pancreatitis classified as complicated in a large number of patients could not be correctly predicted with the Ranson, Glasgow, and APACHE II scoring systems.

Whole Tumor Cell Vaccine Adjuvants: Comparing IL-12 to IL-2 and IL-15

Cancer immunotherapy (passive or active) involves treatments which promote the ability of the immune system to fight tumor cells. Several types of immunotherapeutic agents, such as monoclonal antibodies, immune checkpoint inhibitors, non-specific immunomodulatory agents, and cancer vaccines are currently under intensive investigation in preclinical and clinical trials. Cancer vaccines induce permanent activation of the immune system and may be considered the most promising method for cancer treatment, especially in combination with other agents of passive immunotherapy. Among various approaches to cancer vaccines, whole tumor cell vaccines have been attracting attention for several years. Despite their low to moderate clinical effects, these vaccines have numerous advantages. Their ability to generate immune responses against tumor-associated antigens reduces the possibility for tumor cells to escape and facilitates the development of “off-the-shelf” allogeneic tumor vaccines. Understanding the reciprocal interactions between tumor cells and leukocytes is a key to harness the full potential of whole cell vaccination. Cytokines are considered as potent immunomodulatory molecules which behave as adjuvants in whole tumor cell vaccines. Improved mechanistic understanding of key cytokines in tumor immunity will serve as a resource for rational design of whole cell cancer vaccines. Although there are several reports about the use of different immunostimulatory cytokines as adjuvants, interleukin (IL)-12 appears to have superior effects compared to other cytokines. This review describes the effects of IL-12 compared to other immunomodulatory cytokines, such as IL-2 and IL-15, and highlights its application in whole cell tumor vaccination.
