Review: cytokine involvement in ovarian processes

Area of Science:

• Reproductive Endocrinology
• Immunology
• Gynecologic Oncology

Background:

• Tumor necrosis factor-alpha (TNF) and interleukins-1 alpha/beta (IL-1) are expressed in the ovary.
• These cytokines are involved in ovarian follicular development, atresia, ovulation, steroidogenesis, and corpus luteum function.
• Abnormalities in these processes are linked to ovarian cancer and sepsis-induced ovarian dysfunction.

Purpose of the Study:

• To review the multifaceted roles of TNF and IL-1 in ovarian physiology and pathology.
• To elucidate the mechanisms by which these cytokines affect steroidogenesis, ovulation, and corpus luteum function.
• To understand their involvement in ovarian cancer and sepsis.

Main Methods:

• Literature review of studies on TNF and IL-1 in ovarian function.

Main Results:

• TNF and IL-1 inhibit steroidogenesis in undifferentiated ovarian cells but can stimulate progesterone in differentiated cells.
• These cytokines play a role in ovulation, with increased levels during the preovulatory period.
• TNF and IL-1 affect corpus luteum function, influencing progesterone secretion and regression, and are implicated in ovarian cancer cell growth.

Conclusions:

• TNF and IL-1 are key multifunctional cytokines with diverse effects on ovarian processes.
• Their dysregulation contributes to ovarian pathologies, including cancer and sepsis-related dysfunction.
