Interleukin-8 (IL-8) is produced in the human endometrium. Its messenger RNA (mRNA) expression varies across the menstrual cycle, suggesting hormonal regulation and potential roles in immune cell recruitment.

Area of Science:

  • Reproductive Biology
  • Immunology
  • Molecular Biology

Background:

  • Interleukin-8 (IL-8) is a cytokine involved in neutrophil and T cell chemotaxis.
  • Previous studies indicated IL-8 production by human endometrial cells in culture.

Purpose of the Study:

  • To investigate the temporal and spatial expression of IL-8 mRNA and protein in the human endometrium throughout the menstrual cycle.

Main Methods:

  • Analysis of 52 endometrial tissue samples from different menstrual cycle phases.
  • Northern blot hybridization for IL-8 mRNA detection.
  • Immunohistochemistry for IL-8 protein localization.

Main Results:

  • IL-8 mRNA levels were significantly higher in the late secretory and early to midproliferative phases compared to midcycle.

  • IL-8 protein was consistently found in the surface epithelium and glands.
  • No detectable IL-8 protein was observed in stromal cells.
  • Conclusions:

    • IL-8 is produced in the human endometrium in vivo.
    • Sex hormones likely regulate IL-8 gene expression during the menstrual cycle.
    • IL-8 may play a role in orchestrating immune cell presence in the endometrium.
