The level of interferon-γ was also increased, by 44.3% in the first trimester of pregnancy and by 46.8% at 28-30 weeks, compared to the control group. The level of interleukin-4 did not significantly differ between the studied groups. The level of placental growth factor was reduced in pregnant women with preeclampsia at all stages of gestation, and at 28-30 weeks was reduced by 67.9% compared to the control group. The level of vascular endothelial growth factor was also reduced, by 75%, compared with the control group. An increase in the level of pro-inflammatory cytokines and decrease in growth factors may therefore be considered as potential predictors of the development of preeclampsia, and evaluation of these factors may be advocated in pregnant women with risk factors of preeclampsia.</p>","PeriodicalId":11749,"journal":{"name":"European cytokine network","volume":"35 2","pages":"21-27"},"PeriodicalIF":2.2,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142343955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the precise role of IL-37 in the development of EC remains largely unknown. In the current study, we aimed to explore genotype and allele frequencies of the IL-37 gene (rs4241122) and measure IL-37 protein levels in patients with EC, with a view to determining the clinical significance in these patients. A total of 105 patients with confirmed EC and 105 healthy controls, aged 31-73, participated in the study. IL-37 serum levels were investigated using an ELISA method, while the frequency of genotypes and alleles of the IL-37 gene was determined using the ARMS-PCR method. The findings demonstrate a significant increase in IL-37 serum levels in EC patients compared to controls (p<0.0001). Moreover, higher levels of IL-37 were strongly associated with unfavourable indices, such as EC grade III, poorly differentiated tumours, and regional spread of tumour cells (p<0.05).

During this process, spermatogonial cells proliferate and differentiate via meiotic and post-meiotic stages to produce mature sperm. This process is under the regulation of testicular autocrine/paracrine factors. In addition, endocrine factors are crucial to complete spermatogenesis. We aimed to localize granulocyte-macrophage colony-stimulating factor (GM-CSF) and its receptor (GM-CSFR) in testicular cells and further evaluate its involvement in the development of spermatogenesis in vitro. We isolated cells from seminiferous tubule cells of seven-day-old mice and cultured them in vitro using a methylcellulose culture system (MCS), in the presence of GM-CSF and/or testosterone for four weeks. The cells were then examined for markers of different stages of spermatogenesis by immunofluorescence staining and/or qPCR analyses. Our results revealed the presence of GM-CSF and GM-CSFR in testicular cells (premeiotic and meiotic cells as well as somatic cells; Leydig and Sertoli cells). We further demonstrated the development of colonies/spheroids in the MCS which contained pre-meiotic, meiotic, and post-meiotic cells. The addition of GM-CSF to the MCS significantly increased the percentage of pre-meiotic and meiotic cells compared to control. Furthermore, the addition of GM-CSF and testosterone together significantly increased the percentage of cells in the post-meiotic stage compared to the addition of each separately. In conclusion, our results indicate that testicular cells express GM-CSF/GM-CSFR, and that GM-CSF is involved in the development of different stages of spermatogenesis in vitro. Furthermore, testosterone enhances the development of spermatogenic cells and potentiates the effect of GMCSF on the development of post-meiotic cells. These findings provide evidence that GM-CSF and testosterone are involved in the development of spermatogenesis in vitro and in vivo.
