“…In order to investigate the secretion of these substances in an in vitro study, granulosa cells were separated from FF by a slightly modified procedure that was previously described for IVF-ET [16,17]. Briefly, in order to remove the erythrocytes, the cell suspension was gently treated with lymphocyte separation medium (LSM), then centrifuged at 3000 rpm for 20 min.…”

In order to investigate the role of interleukin-6 (IL-6) and interleukin-6 soluble receptor (sR) in human ovulation, we evaluated the concentrations in human follicular fluid and analyzed the correlation of IL-6 and IL-6 sR with oocyte maturation. The oocytes were obtained from the follicular fluid of 45 women undergoing in vitro fertilization and embryo transfer. The concentrations of IL-6 and IL-6 sR in follicular fluid were measured by ELISA. In addition, granulosa cells obtained from the follicular fluid were cultured and treated with forskolin and 12- o-tetradecanoylphorbol 13-acetate for 24-48 h. The concentration of IL-6 was significantly higher in the follicular fluid than in the serum (P<0.01). In contrast, the concentration of IL-6 sR was significantly lower in the follicular fluid than in the serum (P<0.001). The concentrations of IL-6 and IL-6 sR were significantly higher in the follicular fluid containing mature oocytes than in fluid containing immature oocytes (P<0.05). The production of IL-6 was markedly increased over the basal level after 24 h of treatment with forskolin (P<0.001) and 48 h of treatment (P<0.01) with cultured granulosa cells. Our data suggest that IL-6 and IL-6 sR may play an important role in follicular growth and development in human preovulatory processes. It is possible that IL-6 in particular may be regulated by cAMP. IL-6 and IL-6 sR might also be valuable biochemical markers in the evaluation of oocyte maturation.

Background: In order to investigate the roles of epidermal growth factor (EGF) and transforming growth factor (TGF)-α in ovulation, we studied the production of interleukin (IL)-8 and growth-regulated oncogene (GRO)-α in cultured human granulosa-lutein cells. Methods: Granulosa-lutein cells obtained from the follicular fluids of in vitro fertilization and embryo transfer patients were cultured and treated with EGF, TGF-α, tumor necrosis factor (TNF)-α or 12-O-tetradecanoylphorbol 13-acetate (TPA). An immortalized granulosa cell line (GC1a) was also cultured and treated with EGF, TGF-α or mitogen-activated protein kinase kinase inhibitor. The supernatants were collected, and IL-8 and GRO-α were measured by ELISA. Results: The levels of IL-8 and GRO-α were significantly increased after treatment with EGF, TGF-α, TNF-α and TPA by primary cultured granulosa-lutein cells. The levels of IL-8 and GRO-α were also significantly increased after treatment with EGF or TGF-α in a dose-dependent manner by GC1a. When GC1a was treated with EGF, TGF-α or U0126, the levels of IL-8 and GRO-α were significantly decreased. Conclusion: Our data indicate that the production of IL-8 and GRO-α is upregulated by EGF and TGF-α. It is suggested that EGF and TGF-α may play an important role in luteinization processes involving IL-8 and GRO-α production.

A role for the chemokine receptor CCR6 in mammalian sperm motility and chemotaxis

et al. 2013

Although recent evidence indicates that several chemokines and defensins, well-known as inflammatory mediators, are expressed in the male and female reproductive tracts, the location and functional significance of chemokine networks in sperm physiology and sperm reproductive tract interactions are poorly understood. To address this deficiency in our knowledge, we examined the expression and function in sperm of CCR6, a receptor common to several chemoattractant peptides, and screened several reproductive tract fluids for the presence of specific ligands. CCR6 protein is present in mouse and human sperm and mainly localized in the sperm tail with other minor patterns in sperm from mice (neck and acrosomal region) and men (neck and midpiece regions). As expected from the protein immunoblotting and immunofluorescence results, mouse Ccr6 mRNA is expressed in the testis. Furthermore, the Defb29 mRNA encoding the CCR6 ligand, β-defensin DEFB29, is expressed at high levels in the epididymis. As determined by protein chip analysis, several chemokines (including some that act through CCR6, such as CCL20/MIP-3α (formerly Macrophage Inflammatory Protein 3α) and protein hormones were present in human follicular fluid, endometrial secretions, and seminal plasma. In functional chemotaxis assays, capacitated human sperm exhibited a directional movement towards CCL20, and displayed modifications in motility parameters. Our data indicate that chemokine ligand/receptor interactions in the male and female genital tracts promote sperm motility and chemotaxis under non-inflammatory conditions. Therefore, some of the physiological reactions mediated by CCR6 ligands in male reproduction extend beyond a pro-inflammatory response and might find application in clinical reproduction and/or contraception.

The Production and Clinical Evaluation of Macrophage Colony‐Stimulating Factor and Macrophage Chemoattractant Protein‐1 in Human Follicular Fluids

Abstract: Our data suggest that M-CSF and MCP-1 may play an important role in human preovulatory processes and that M-CSF, in particular, may be regulated by cyclic adenosine monophosphate. M-CSF and MCP-1 may also be valuable biochemical markers in the evaluation of oocyte maturation.
