Metalloproteinases (MMPs) and cytokines have a great impact on the pathogenesis of psoriasis. Cytokines, as key mediators of inflammation and autoimmune processes, play a crucial role in the regulation of MMP expression in different cell types. Parallel, MMPs have an influence on cytokine production. This interaction was not well recognized in psoriatic patients. Our study is aimed at assessing the selected serum MMP levels and their correlations with cytokine levels in the serum of psoriatic patients. We observed a significantly elevated level of pro-MMP-1 and MMP-9 in psoriatic patients’ serum in comparison to the control group. We did not observe any statistically significant differences of MMP-3 and pro-MMP-10 between the psoriatic patients and the control group. We did not observe any statistically significant differences in all the studied MMP levels between the patients with and without psoriatic arthritis (PsA). MMP-3 level correlated positively with proinflammatory cytokines, i.e., IL-12p/70, IL-17A, and TNF-α as well as MMP-3 and pro MMP-1 correlated positively with IL-4 in the psoriatic patients. In the control group, a positive correlation between pro-MMP-1 and TNF-α was found. These results confirm MMPs and Th1 and Th17 cytokine interaction in the inflammatory regulation in psoriasis.

ABSTRACT Introduction: Fabry disease (FD) is a disorder caused by mutations in the gene encoding for lysosomal enzyme α-galactosidase A (α-GAL). Reduced α-GAL activity leads to progressive accumulation of globotriaosylceramide (Gb3), also known as CD77. The recent report of increased expression of CD77 in blood cells of patients with FD indicated that this molecule can be used as a potential marker for monitoring enzyme replacement therapy (ERT). Objective: The purpose of this study was to evaluate the CD77 levels throughout ERT in FD patients (V269M mutation). Methods: We evaluated the fluctuations in PBMC (peripheral blood mononuclear cell) membrane CD77 expression in FD patients undergoing ERT and correlated these levels with those observed in different cell types. Results: A greater CD77 expression was found in phagocytes of patients compared to controls at baseline. Interestingly, the variability in CD77 levels is larger in patients at baseline (340 - 1619 MIF) and after 12 months of ERT (240 - 530 MIF) compared with the control group (131 - 331 MFI). Furthermore, by analyzing the levels of CD77 in phagocytes from patients throughout ERT, we found a constant decrease in CD77 levels. Conclusion: The increased CD77 levels in the phagocytes of Fabry carriers together with the decrease in CD77 levels throughout ERT suggest that measuring CD77 levels in phagocytes is a promising tool for monitoring the response to ERT in FD.

The advantage in response of Th2 over Th1 is observed in normal pregnancy in peripheral blood. A disturbance of this balance can lead to symptoms of miscarriage and pregnancy loss. The aim of this study was to evaluate the pro- and anti-inflammatory cytokines in sera of women who were diagnosed with missed miscarriage in the first trimester and to compare this systemic immune response to the response in women with normal pregnancy. The study group consisted of 61 patients diagnosed with missed miscarriage. In total, 19 healthy women with uncomplicated first trimester created the control group. Cytokines were determined in the maternal serum by ELISA. The analysis included INF-γ, TNF-α, Il-1β, Il-4, Il-5, Il-6, Il-9, Il-10, Il-13 and TGF-β1. Th1 cytokine levels in the study group reached slightly higher values for INF-γ, Il-1β and slightly lower for IL-6 and TNF-α. In turn, Th2 cytokine levels in the study group were slightly higher (Il-9, Il-13), significantly higher (Il4, p = 0.015; Il-5, p = 0.0003) or showed no differences with the control group (Il-10). Slightly lower concentration involved only TGF-β1. Analysis of the correlation between levels of pro- and anti-inflammatory cytokines resulted in some discrepancies, without showing predominance of a specific immune response. The results did not confirm that women with missed miscarriage had an advantage in any type of immune response in comparison to women with normal pregnancy.

Abstract Background: We investigated bilateral tear cytokine levels including interleukin (IL)-1β, IL-10, IL-17, tumor necrosis factor (TNF)-α and Matrix metalloproteinase-9 (MMP-9) in patients with fungal keratitis(FK). Meanwhile, we evaluated the relationship between the changes of tear cytokines with corneal perception and pain in infected eyes, and the relationship between tear cytokines and tear film function in contralateral uninfected eyes .Methods : A total of 60(20 FK, 20 contralateral, 20 healthy controls) tear samples were collected prospectively and analyzed by enzyme linked immunosorbent assay(ELISA). Approximately 50 to 60 ul of tear samples in each case were collected. Meanwhile ,we analyzed the changes of visual analogue scale(VAS), tear breakup time (TBUT), Schirmer I test (SIT) and corneal perception compared with healthy controls. Results :The concentrations of IL-1β, IL-10 and IL-17 increased in bilateral eyes compared with healthy controls(P<0.05). The tear concentrations of MMP-9 , TNF-α only significantly increased in affected eyes (P <0.05). Patients with FK showed significant reduction in corneal perception of infected eyes compared with controls(P<0.05). Corneal perception of the normal eyes in FK patients was slightly lower than that of control group, but there was not statistical difference (P>0.05).TBUT and SIT of contralateral uninfected eyes were significantly lower than that of control group(P<0.05), which were significantly correlated with levels of IL-1β, IL-17(P<0.05). SIT were also negatively correlated with MMP-9(P<0.05), while the levels of IL-1β, IL-10, IL-17, TNF-α and MMP-9 in the tears of the healthy control group had no significant correlation with TBUT and SIT indicators(P>0.05).The corneal perception and VAS score of the affected FK eyes showed correlation with IL-1β, IL-17 and TNF-α(P<0.05).In addition, concentration of IL-10 inversely was correlated with VAS (P<0.05). Conclusion: Proinflammatory tear cytokines are elevated in bilateral eyes with unilateral FK as associated with tear film function ,pain and corneal sensitivity.

Rosiglitazone Treatment

Abstract Objectives: Our objectives were to evaluate the effect of rosiglitazone on bone metabolism and to assess the association between changes in bone turnover parameters and plasma cytokine levels in postmenopausal diabetic women. Design: This was a 12-wk open-label randomized-controlled trial. Patients or Other Participants: A total of 56 obese postmenopausal women with newly diagnosed diabetes and 26 nondiabetic healthy controls matched for age and body mass index were included in the study. Interventions: The subjects were instructed to follow a weight-maintenance diet. Half were randomly assigned to receive rosiglitazone 4 mg/d, and the other half remained on diet alone. Main Outcome Measures: Before and after the interventions, metabolic bone markers and serum cytokine levels were assessed. Results: Serum total alkaline phosphatase (ALP) and bone-specific ALP levels were statistically significantly lower 12 wk after initiation of rosiglitazone treatment. There were no statistically significant changes in osteocalcin levels among the three groups or in deoxypyridinoline levels in the rosiglitazone group. At the end of 12 wk, all patients had statistically significantly decreased IL-1β and TNF-α levels compared with baseline. Changes in bone-specific ALP levels showed a moderate negative correlation with the changes in the TNF-α levels after rosiglitazone treatment and after diet in the diabetic control group. Conclusions: Rosiglitazone use is associated with reduced bone formation at earlier stages in postmenopausal diabetic women. The cytokine-lowering effects of rosiglitazone and lifestyle changes could reverse the early inhibitory effect of rosiglitazone therapy on bone formation. Further studies will clarify the long-term effects of rosiglitazone therapy on bone loss and fracture.

Abstract Objective: to observe the effects of moxibustion on histomorphological changes of gastric mucosa, as well as on serum IL-6、IL-8、TNF-α，Hp IgG、CD3+、CD4+、CD8+ in helicobacter pylori (Hp) infected rats, so that to better understand how the moxibustion repairs the Hp- induced gastric mucosal injury. Methods: 40 SD rats were randomly assigned to four groups: group A (blank control), group B (Hp infection model), group C (moxibustion plus model), group D (electro-acupuncture plus model), 10 for each group. The “NaHCO3 plus Indometacin and Hp intragastric administration” method was employed to make gastritis model. Acupoints selected for “repair” purpose were Zu San Li (ST36), Zhong Wan (CV12), Guan Yuan (RN4), Pi Shu (BL20), Wei Shu(BL21). The histomorphological changes of gastric mucosa in rats were observed under light microscope after HE stain; IL-6, IL-8, TNF-α, Hp IgG values were evaluated by ELISA method; values of CD3+、CD4+、CD8+、CD4+/CD8+ were measured by flow cytometry method. Results: compared with group A, the values of IL-6, IL-8, TNF-α, Hp IgG and CD8+ in group B were increased（P＜0.01）, whereas the values of CD3+、CD4+、CD4+/CD8+ were decreased（P＜0.01）. Compared with group B, the values of IL-8（P＜0.05）,TNF-α（P＜0.05）, IL-6（P＜0.01）, Hp IgG（P＜0.01） and CD8+ （P＜0.05） in group C were decreased, whereas the values of CD3+（P＜0.05）,CD4+（P＜0.05）,CD4+/CD8+ （P＜0.05） were increased, meanwhile such values in group D had no significant changes. Compared with group D, the values of IL-6（P＜0.05）,IL-8 （P＜0.05）and Hp IgG （P＜0.01）in group C were decreased, whereas CD4+/CD8+（P＜0.05）were increased, all those changes had statistical significance. Conclusion: the preventive and therapeutic effects of moxibustion on Hp related gastritis might be realized by two ways- to inhibit the secretion of proinflammatory cytokines such as IL-6, IL-8 and TNF-α, or to regulate the production of immune factors (such as up-regulation of CD3+, CD4+ and down-regulation of CD8+).

The release of the cytokines interleukin (IL)-1α, IL-1β, IL-6, IL-8, and tumor necrosis factor alpha (TNF-α was measured from epiderm alkeratinocytes in an attempt to characterize the immunologic response in keratinocytes following exposure to bis (2-chloroethyl)sulfide (sulfur mustard, HD). Enzyme-linked immunosorbentassay (ELISA) was used to measure cytokine levels in adult and neonatal culture human epidermal keratinocytes (HEK) 3 h after exposure to 0.50 and 1.0 m M HD. A two-way analysis of variance was carried out for cell type and HD concentration. That analysis showed significant differences between cell types for IL-1α and IL-1β(p =.001 and p =.015, respectively). In both of these cytokines, release in neonatal HEK decreased less than in adult HEK. A significant effectof HD concentration was shown only for IL-1β (P <.001), with cytokine release decreasing with increasing HD dose. In addition, a significant cell donor type by HD concentration interaction effect was found for IL-1β under the experimental conditions described in materials and methods. With increasing HD concentration, the relative decrease in cytokine release was much greater for adult than for neonatal HEK.

2584 Background: PD-1 inhibitors have transformed the treatment landscape for patients (pts) with many advanced malignancies. Combination therapy with PD-1 inhibitors for cancer is a trend. However, Biomarkers for the efficacy of combination therapy remains unknown. In order for the benefited population to be screened out, biomarkers need to be established. we will conduct the following study, to explore the IFN-α, IFN-γ, IL-2 combined with TNF-α for predicting efficacy of PD-1 inhibitors combination therapy. Methods: Using postoperative without lesions as control group (n=7). Pts with lesions as the experimental group (n=66). 27 of 66 pts received chemoradiotherapy (group A), 39 of 66 pts received PD-1 inhibitors combined with therapy (group B). IFN-α, IFN-γ, IL-2, TNF-α in peripheral blood of all pts were measured using flow cytometry. Results: 1) There was significant difference in proportion above normal concentrations (ANCs) of IFN-α between two groups (57.1% vs 43.5%, P<0.05), but there was no significant difference in IFN-γ, IL-2 and TNF-α between two groups (IFN-γ 57.1% vs 52.2%, IL-2 14.3% vs 5.8%, TNF-α 42.9% vs 43.5%, P>0.05). 2) The normal ratios of IFN-α, IFN-γ and TNF-α in group B was significantly higher than that in group A (IFN-α 64.1% vs 51.9%, IFN-γ 59% vs 37%, TNF-α 69.2% vs 44.4%, P<0.05). The proportion ANCs of IFN-α, IFN-γ, and TNF-α were lower in group A (IFN-α 35.9% vs 63%, P>0.05; IFN-γ 41% vs 63%, P<0.05; TNF-α 30.8% vs 55.6%, P<0.05). However, the proportion ANCs of IL-2 detection was lower (7.4% vs 5.1%). 3) In group B, 21 of 39 pts were evaluable. ORR was 52.4% (11/21) and DCR was 85.7% (18/21). The proportion ANCs of IFN-α, IFN-γ and TNF-α in the pts with PR was higher than that with SD (IFN-α 37.5% vs 28.6%, IFN-γ 37.5% vs 28.6%, TNF-α 50% vs 38.8%, P<0.05). 4) We found that the coincidence rate of IFN-α+ IFN-γ and IFN-α+ IFN-γ+TNF-α was higher in group B (Table). Conclusions: Our results suggest that the proportion ANCs of IFN-α, IFN-γ, and TNF-α in the pts with lesions were lower than that without lesions, it may be the decrease of immune function with lesions. There was positive correlation between proportion ANCs of IFN-α, IFN-γ and TNF-α and efficacy in these pts. IL-2 was not used as a routine detection indicator. The coincidence rate of IFN-α, IFN-γ combined with TNF-α was higher, it may help predict the outcome of PD-1 inhibitors combination therapy in pts with solid cancers, and helpful to screen the benefit population. Further study is needed.[Table: see text]

The objective of this study was to investigate whether serum cytokine levels correlate with depression and anxiety in colorectal cancer (CRC) patients. Twenty patients hospitalized for surgical resection of CRC were included in the study group and twenty healthy volunteers comprised the control group. Depression and anxiety were analyzed using the Hospital Anxiety and Depression Scale (HADS), and serum levels of IL-1β, IL-6, IL-8, IL-10, IL-12, TNF-α, and TGF-βwere measured by Cytometric Bead Array. We found that more than half of CRC patients presented clinically significant levels of anxiety or depression, and 65% of them manifested a combination of severe anxiety and depression. CRC patients had increased serum levels of IL-1β, IL-6, IL-8, and TNF-α but lower IL-10 concentrations. Correlation analysis between HADS score and cytokine levels revealed a positive association of anxiety and/or depression with IL-1β, IL-6, IL-8, and TNF-α and a negative correlation with IL-10. These results indicate that circulating proinflammatory cytokines are involved in the pathophysiology of anxiety and depression in CRC patients. A better understanding of the molecular mechanisms involved in these psychological disorders will allow the design of therapeutic interventions that lead to an improved quality of life and overall survival of CRC patients.

Background: Stress that is induced by sleep deprivation can modulate the damage of periodontal tissue by elevating the levels of proinflammatory cytokines (i.e. IL-1β and TNF-α). The effects of sleep deprivation can be resolved with sleep recovery. Gingival crevicular fluid (GCF) is fluid in sulcular gingiva which acts as an oral biomarker for evaluating periodontal abnormalities. Purpose: The aim of this study was to determine the effect of various induction methods of sleep deprivation stress on cytokine levels in GCF of white male Wistar strain rats (Rattus novergicus). Methods: The study method was true experimental with a posttest-only control group design. Thirty male Wistar rats were randomly divided into five groups: paradoxical sleep deprivation (PSD), total sleep deprivation (TSD), partial sleep deprivation with sleep recovery for five days (PSD+SR), total sleep deprivation with sleep recovery for five days (TSD+SR) and a healthy control group. Data were analysed via one-way ANOVA to determine differences between groups. Result: The results showed the highest level of IL-1β and TNF-α was found in the PSD group. One-way ANOVA analysis showed significant differences (p<0,05) of IL-1β level between PSD and control groups, PSD and PSD+SR groups and PSD and TSD+SR groups; in contrast, the analysis of TNF-α levels showed significant differences (p<0,05) between PSD group to control group, PSD to PSD+SR group and TSD to TSD+SR group. Conclusions: There is an effect of various induction methods of sleep deprivation stress on proinflammatory cytokines (IL-1β and TNF-α).

Chitosan, a natural product derived from chitin, has attracted much attention as a promising polysaccharide compound, owing to its unique biological activities. This study was designed to explore the possible improving potential of chitosan, as a natural marine product, on liver regeneration in hepatotoxicity induced by thioacetamide in male albino rats. Fifty animals were divided into 5 groups, including the control group; a group which was injected intraperitoneally with a single dose of thioacetamide(300 mg/kg b. wt) for induction of liver toxicity; a group received a diet containing 5% chitosan for 14 days; a group received a diet containing 5% chitosan for 14 days then they were injected with thioacetamide(300 mg/kg b. wt) once, and the last group which was injected with thioacetamide(300 mg/kg b. wt) once then received a diet containing 5% chitosan for 14 days. The biochemical results revealed that the intake of chitosan before or after thioacetamide intoxication improved liver markers (ALAT, ASAT, GGT, ALP, albumin) and kidney functions and also plasma TNF-α. QRT- PCR analysis revealed that chitosan downregulated hepatic TNF-α, survivin, and c-Myc quantitative gene expression. Moreover, chitosan improved the histological picture of the liver. This study indicated the promising action of chitosan in liver regeneration.
