ABSTRACT
OBJECTIVE:
Seminal plasma (SP) contains large numbers of sub-cellular structures called extracellular vesicles (EV) which have been postulated to have immunological functions due to their bioactive contents including proteins and small non-coding RNAs. Although the response of endometrial cells to seminal EV (SEV) is recently being elucidated, the impact of these signaling vesicles on stroma-immune crosstalk is still unknown. Herein, we aimed to investigate the effect of conditioned medium (CM) derived from SEV-exposed endometrial stromal cells (eSC) on cytokine secretion by macrophages. STUDYDESIGN:
SEV were isolated from SP samples of healthy donors and characterized by common methods needed for EV characterization, including size determination by dynamic light scattering (DLS), transmission electron microscopy (TEM), and western blot analysis of EV markers. Endometrial biopsies were obtained from healthy individuals and eSC were isolated and characterized. EV internalization assay was performed by labeling the SEV with PKH67 green fluorescent dye. Then, the eSC were exposed to SEV and the CM was collected. Finally, the CM from SEV-exposed eSC was added to the macrophage culture and the level of inflammatory (interleukin (IL)-1α and IL-6) and anti-inflammatory (IL-10) cytokines were measured in the culture supernatant of macrophages.RESULTS:
The results demonstrated that the CM derived from SEV-exposed eSC induce IL-1α and IL-6 secretion by the macrophages, while the secretion of IL-10 was reduced.CONCLUSION:
Our results support the idea that the stroma-immune interaction is affected by SEV. This effect may be a part of immunoregulatory function of SP inside upper female genital tract and have an obvious impact during peri-implantation period.Palavras-chave
