Expression of interleukin-22 in decidua of patients with early pregnancy and unexplained recurrent pregnancy loss

Purpose

Researchers have hypothesized that an imbalance of immune cells in the uterine decidua and a dysfunction in cytokines they produce may contribute to recurrent pregnancy loss (RPL). The objective of this study was to determine if IL-22, IL-23 and IL-17 are expressed abnormally in the decidua of patients with RPL compared to those women with a normal pregnancy. We also sought to confirm that uterine natural killer (uNK) cells are lower in the decidua of patients with RPL, as well as identify IL-22 expression by uNK cells.

Methods

After meeting strict inclusion criteria, maternal decidua of nine patients with unexplained RPL and a confirmed euploid fetal loss, and 11 gestational age-matched patients undergoing elective pregnancy termination were included in our analysis. Quantitative real time-polymerase chain reaction (qRT-PCR) was performed to quantify RNA expression, Western blot was performed to quantify protein expression and immunohistochemistry (IHC) was performed to identify IL-22 and uNK cells.

Results

We found that women with unexplained RPL and a euploid fetal loss had significantly less gene and protein expression of IL-22 in the decidua. Additionally, we found that IL-22 is primarily expressed by uNK cells in the decidua.

Conclusions

In conclusion, our results suggest that lower levels of IL-22 in the uterine decidua in patients with unexplained RPL may contribute to a disruption of decidual homeostasis and ultimately lead to early pregnancy loss.

Effect of T-helper 1 cytokines on secretion of T-helper 2 cytokines by term trophoblast cells in culture

A successful pregnancy has been postulated to be the result of a discrete balance between T-helper 1 (Th1) and T-helper 2 (Th2) type cytokines involved in growth and development of the conceptus. The aim of the present study was to examine the effect of Th1 cytokines (interleukin- 1β (IL- 1β) and tumor necrosis factor-alpha (TNFα)) on the release of Th2 cytokines including IL-6 and IL-10 by trophoblast cells obtained from term placenta. Trophoblast cells isolated by enzymatic disaggregation and Percoll gradient fractionation were cultured in supplemented medium alone or with varying concentrations of the selected recombinant cytokines. After 48 h of incubation, samples of the culture supernatant were analyzed for the Th2 cytokines IL-6 and IL-10 using specific ELISA assays. Both IL-1β and TNFα had no effect on the cell number and viability as determined by MTT assay. IL-1β significantly stimulated trophoblast release of IL-6 in a dose-dependent manner (3.3-, 5.5-, 10.3- and 22 4-fold higher compared to the control at 10, 50, 100, 500 U IL-1β/ml respectively, p < 0.05). TNFα also stimulated release of IL-6 by these cells. However, the stimulation at lower concentrations was not very high and a significant (p < 0.05) stimulation was observed only at higher concentrations (1.1-, 1.3-, 2.6- and 5.9-fold higher at 500, 1000, 1500, 2000 U TNFα/ml respectively). In contrast, neither IL-1β or TNFα exerted any significant effect on IL-10 release by term trophoblast cells (p > 0.05). The results of this study provide evidence that production of Th2 cytokines might be under the control of different regulatory pathways.     

Expression imbalance of IL-17/IL-35 in peripheral blood and placental tissue of pregnant women in preeclampsia

ObjectivesThe possible mechanism of preeclampsia is investigated in this study to facilitate the exploration of the future remediation of this disease by analysing the changes of IL-17 and IL-35 in peripheral blood and placental tissue of pregnant women with preeclampsia (PE).Materials and methodsThe study was conducted using 45 healthy pregnant women as the control group and 90 pregnant women in the preeclampsia group, including 45 cases with severe preeclampsia and 45 cases with mild preeclampsia. All of 135 pregnant women underwent caesarean delivery. IL-17 and IL-35 concentrations in the serum were measured by ELISA, and IL-17 and IL-35 expression in placental specimens was detected by immunohistochemistry.ResultsThere were no statistically significant differences in age among the three study groups. Serum IL-17 levels were significantly higher in PE patients than in healthy pregnant women (P < 0.01). The ratio of positive staining for IL-17 was markedly higher in mild PE tissues (84.44%; 38/45) and severe PE tissues (86.67%; 39/45) than in healthy pregnant tissues (35.56%; 16/45) (P < 0.01). The strong positive rates for IL-17 were markedly higher in mild PE tissues (48.89%; 22/45) and severe PE tissues (68.89%; 31/45) than in healthy pregnant tissues (13.33%; 6/45) (P < 0.01). No differences between mild PE tissues and severe PE tissues were noted in both positive case rates and strong positive rates. Consistent with this finding, the ratio of strong positive staining for IL-35 was higher in healthy pregnant tissues (66.67%; 30/45) than in mild PE tissues (33.11%; 14/45) and severe PE tissues (26.67%; 12/45) (P < 0.01).ConclusionsThe abnormal increase in serum and placental of IL-17 has an association with the formation and development of PE. IL-35 expression is significantly lower in severe PE placenta tissue and serum compared with normal pregnant women. These results suggested that IL-17/IL-35 imbalance may play a role in the pathophysiology of PE.

【摘 要】 目的：检测子宫腺肌病在位/异位内膜Toll样受体（Toll-like receptors,TLRs）表达,探讨TLRs表达与组织炎症病理的相关性。方法：标本选自同济大学附属杨浦医院收治的子宫腺肌病手术患者24例,分别取在位内膜（eutopic endometrium,EU）、异位内膜（ectopic endometrium,EC）,并以正常子宫内膜（control endometrium,CE）为对照。检测CE、EU、EC组中TLRs mRNA及蛋白表达,同时检测白细胞介素（IL）-6、IL-8 mRNA表达。结果：逆转录聚合酶链反应（RT-PCR）检测显示：IL-6、IL-8 mRNA在EC、EU组中表达均高于CE组（P＜0.01）,且EC组高于EU组（P＜0.01）。TLR1～6、8、9 mRNA在EC、EU组中表达高于CE组（P＜0.05）,除外TLR2,其余TLRs在EC组中表达高于EU组（P＜0.01）。TLR7 mRNA在EU组中表达高于CE组（P＜0.05）,而EC组与CE组、EU组与EC组之间差异无统计学意义。蛋白质印迹（Western blot）检测显示：TLR1、4～6、8、9在EC、EU组中表达高于CE组（P＜0.01）,且EC组高于EU组（P＜0.01）。TLR2在EC组中表达高于CE组（P＜0.05）,而EU组与CE组、EU组与EC组之间差异无统计学意义。TLR3、7在EC组中表达高于EU组及CE组（P＜0.05）,而EU组与CE组之间差异无统计学意义。Pearson相关性分析显示,子宫腺肌病EU、EC组TLRs mRNA与IL-6、IL-8均呈正相关;其中TLR2、4、5、9与IL-6、IL-8均呈正相关（P＜0.05）。结论：子宫腺肌病病灶处于炎症病理状态,腺肌病EU、EC组TLRs整体呈高表达,并与IL-6、IL-8具有良好的相关性,提示TLRs信号介导免疫炎性体系可能涉及子宫腺肌病炎症病理形成及发展。     

Interleukin-6 and interleukin-1 receptor antagonist in amniotic fluid and cord blood in patients with pre-term, premature rupture of the membranes.

OBJECTIVE: We investigated the role of interleukin (IL)-6 and IL-1 receptor antagonist (IL-1ra) in pre-term premature rupture of the membranes (PROM). METHOD: Amniotic fluid samples were collected from 10 patients with pre-term PROM (group 1a), 13 patients undergoing genetic amniocentesis (group 2), seven patients with normal vaginal delivery (group 3a), and 11 patients with elective cesarean section (group 4a). Umbilical venous blood was collected from nine cases of pre-term PROM (group 1b), 19 cases of normal delivery (group 3b) and nine cases of elective cesarean section (group 4b). RESULTS: The concentration of IL-6 in the amniotic fluid in group 1a was significantly higher than in group 2 (P<0.001), and that in group 3a was significantly higher than in group 4a (P<0.001). The concentration of IL-1ra in amniotic fluid in group 1a was significantly higher than in group 2 (P<0.001). The concentrations of IL-6 in umbilical venous blood were not significant among the groups. The concentration of IL-1ra in umbilical venous blood in group 1b was significantly higher than in group 3b (P<0.05) and group 4b (P<0.05). CONCLUSIONS: High concentrations of amniotic fluid IL-6 present in pre-term PROM, are indicative of intrauterine inflammation, probably due to sub-clinical infection. The high concentrations of IL-1ra in amniotic fluid and umbilical venous blood suggest the possibility that the presence of this anti-inflammatory cytokine serves to prevent the development of overt inflammation.
