Maternal Circulating TNF-α Levels are Highly Correlated with IL-10 Levels, but not IL-6 and IL-8 Levels, in Women with Pre-Eclampsia

Problem  Several lines of evidence have shown that maternal cytokine levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-8, and IL-10 were altered in women with pre-eclampsia (PE) compared to those from normal pregnancies. In this study, we determined whether these cytokine levels are correlated before and after delivery in patients with PE.
Method of study  Venous blood was obtained from 50 women diagnosed with severe PE at the time of admission and 24 hr after delivery. Plasma concentrations for TNF-α, IL-6, IL-8, and IL-10 were measured by ELISA.
Results  There were no statistical differences for maternal levels of TNF-α, IL-6, IL-8, and IL-10 before and 24 hr postpartum. TNF-α and IL-10, but not IL-6 and IL-8, levels were significantly correlated before and 24 hr after delivery: TNF-α: y  = 19.963 + 0.953* x ; r ² = 0.924; IL-10: y  = 10.521 + 1.113* x ; r ² = 0.984, P  < 0.001, respectively. Furthermore, TNF-α levels were correlated with IL-10 levels, but not with IL-6 and IL-8 levels.
Conclusion  The correlation patterns of TNF-α with IL-10 and TNF-α with IL-6 and IL-8 suggest disparity in functional regulations between these cytokines in maternal circulation in PE.

The regulation of rhinovirus infection in vitro by IL-8, HuIFN-alpha, and TNF-alpha

The influence of three important cytokines (IL-8, TNF-alpha, and HuIFN-alpha) on ongoing rhinovirus infections has been examined in vitro, individually or as combinations. TNF-alpha was able to transform traces of HRV infections into full-blown infections. Furthermore, TNF-alpha was able to down-regulate the antiviral action of HuIFN-alpha completely, even at levels of just a few pg/ml. This suggests that the induction of TNF-alpha by HRV may be part of the virus's strategy to minimize the interferon response which is part of the host's immune defence system. However, troxerutin (a flavonoid) was able to neutralize the downregulatory action of TNF-alpha on the HuIFN-alpha system at low levels and re-establish the antiviral activity ascribed to IFN-alpha. IL-8 exerted a minor influence on the interferon system, and had no influence on rhinovirus infections. The in vitro findings are supported, in part, by recent in vivo findings in a common cold pilot study.

The mycotoxins citrinin and gliotoxin differentially affect production of the pro-inflammatory cytokines tumour necrosis factor-α and interleukin-6, and the anti-inflammatory cytokine interleukin-10

BACKGROUND: Microbial growth is considered one of the major causes of indoor air problems. Moulds have been associated with asthma, allergy and a wide range of diffuse indoor air-related symptoms. However, mechanisms of the adverse health effects are not well understood. OBJECTIVE: We hypothesized that the mycotoxins citrinin and gliotoxin could cause an imbalance between the secretion of the pro-inflammatory cytokines TNF-alpha and IL-6 and the anti-inflammatory cytokine IL-10. METHODS: We investigated the influence of citrinin and gliotoxin on the human monocytic cell line Mono-Mac-6 (MM6) with and without lipopolysaccharide -stimulation. The levels of IL-10, IL-6 and TNF-alpha were analysed in cell culture supernatants by ELISA. Cell viability and cell apoptosis were measured by flow cytometry. RESULTS: The strongest inhibition of cytokine secretion was found for IL-10. IL-6 levels were found to decrease in a dose-dependent manner along with reduced cell viability. TNF-alpha levels increased with low gliotoxin exposure (less than 100 ng/mL), but decreased significantly at 375 ng/mL and higher along with increased cell apoptosis and reduced cell viability. TNF-alpha levels were not reduced by citrinin exposure. CONCLUSION: We observed a cytokine imbalance with a more pronounced reduction of IL-10 concentrations compared with those of TNF-alpha and IL-6. We suggest that low exposure doses of citrinin and gliotoxin (corresponding to less than 100 ng/mL gliotoxin and less than 10 mug/mL citrinin) may inhibit IL-10 and lead to increased risk of an inflammatory response with relative overproduction of TNF-alpha and IL-6. The findings and their clinical implications must be verified by human studies. However, we speculate that the observed biological effects may be of importance as they may partly explain the occurrence of diffuse general indoor air-related symptoms as well as the worsening of asthmatic inflammatory reactions experienced in mouldy environments.     

DHT对卵巢癌细胞IL-6、IL-8及其受体表达的调节作用

目的 初步探讨雄激素对卵巢癌细胞IL-6、IL-8及其受体表达的调节作用及作用机制.方法 选择兼有雄激素受体(AR)、IL-6和IL-8及其受体表达的卵巢癌细胞系SKOV-3和OVCAR-3作为研究模型,观察5a-二氢睾酮(DHT)对IL-6、IL-8及其受体表达以及NF-κB加转录的调节作用.结果 DHT可促进卵巢癌细胞IL-6、IL-8分泌及相应mRNA表达,并增强IL-6基因启动子的转录活性,DHT的上述作用可被AR阻断剂氟他胺完全阻断.DHT显著提高卵巢癌细胞NF-κB加亚单位p50、p65(RelA)mRNA的表达水平,其中对后者的作用与对IL-6、IL-8 mRNA的作用相平行.此外,DHT尚能调节IL-6、IL-8受体的表达.结论 雄激素可能通过NF-κB信号传导途径促进卵巢癌细胞IL-6、IL-8的分泌,同时对二者受体的表达也有一定的凋节作用.

Variations in cervical IL-10 and IL-8 concentrations throughout gestation in normal pregnancies

PROBLEM: Data regarding cervical interleukin 18 (IL-8) and IL-10 concentrations during pregnancy is limited. METHOD OF STUDY: This was a cross sectional study of healthy pregnant women. Specimens were collected from the cervical os secretions. IL-8 and IL-10 levels were measured by using enzyme-linked immunosorbent assay. Median (range) cytokine concentrations were derived for each trimester and compared across trimesters. The relationship between gestational age and cytokine levels was assessed by regression analysis. The mean of the ratios of IL-8 to IL-10 was compared in each trimester using anova. RESULTS: The median (range) IL-8 concentrations in cervical secretions were in pg/mL: 1562 (1210-4100), 2460 (1047-4688), 3660 (1451-4748) (P < 0.0021); the median (range) IL-10 concentrations in cervical secretions were in pg/mL: 38.3 (6.8-227.9), 10.9 (0-263.3), 9.5 (0-35.6); the mean IL10/IL-8 x 100 (+/- standard deviation) concentrations were: 3.33 +/- 0.65, 1.47 +/- 0.41, 0.38 +/- 0.52 (P = 0.0035) during the first, second and third trimesters, respectively. CONCLUSION: The patterns of cervical IL-8 concentration is inversely related to gestational age, and the ratio of IL-10/IL-8 decreases with advancing gestation.
