Description

Cytokines (CK) are critical regulators of immune responses, mediating various physiological and pathological processes. Their roles extend beyond traditional immune functions, influencing reproductive health significantly. This overview examines how CK-induced immune cell infiltration and activation lead to chronic low-grade inflammation, exacerbating follicular apoptosis and atresia and ultimately affecting the quality and quantity of ovarian follicles and Oocytes (OCs).

Cytokines, as signaling proteins, coordinate the immune response by regulating the migration and activation of immune cells. Elevated levels of pro-inflammatory cytokines such as Tumor Necrosis Factor-Alpha (TNF-α), Interleukin-6 (IL-6) and Interleukin-1 Beta (IL-1β) are often associated with various inflammatory conditions. These cytokines can trigger the recruitment of immune cells, such as macrophages, neutrophils and T-cells, to ovarian tissues, leading to massive immune cell infiltration [1,2].

This infiltration is seen in chronic inflammatory states in addition to being a reaction to infection or damage. This can create an environment where immune cells constantly engage with ovarian follicles, which could have negative effects on ovarian health. Persistent cytokine activity can result in chronic low-grade inflammation, a state characterized by sustained but mild inflammation over an extended period. Unlike acute inflammation, which is typically a short-term response to injury or infection, chronic low-grade inflammation is enigmatic and can have long-term adverse effects on tissue function.

In the ovaries, chronic inflammation can alter the local microenvironment, affecting the delicate balance of factors necessary for follicular development and oocyte maturation. The presence of inflammatory cytokines can disrupt normal follicular growth, leading to impaired ovarian function. Cytokines play a significant role in regulating apoptosis, the programmed cell death essential for maintaining tissue homeostasis. However, excessive cytokine activity can lead to increased apoptosis in ovarian follicles, a process that contributes to follicular atresia, the degeneration and subsequent resorption of immature follicles.

Follicular atresia is a normal physiological process that ensures only healthy follicles reach maturity. However, when enhanced by chronic inflammation, the rate of follicular apoptosis can increase abnormally, leading to a reduction in the pool of viable follicles. This not only decreases the number of oocytes available for ovulation but also impacts their quality, which is critical for successful fertilization and embryo development [3-7].

The quality and quantity of oocytes are crucial determinants of reproductive success. Cytokine-induced chronic inflammation can have a profound impact on these parameters. Chronic exposure to inflammatory cytokines can lead to oxidative stress within the ovarian follicles, damaging cellular components, including DNA, proteins and lipids. This oxidative damage can compromise the integrity of oocytes, leading to reduced fertilization potential and poorer embryonic development [8].

Moreover, the reduction in the number of healthy follicles due to increased atresia means fewer oocytes are available for maturation and ovulation. This decline in follicular reserve is particularly concerning for women with conditions such as Polycystic Ovary Syndrome (PCOS) and endometriosis, where chronic inflammation is a known factor [9,10].

Cytokine-induced immune cell infiltration and chronic low-grade inflammation have profound effects on ovarian health, leading to increased follicular apoptosis and atresia and ultimately affecting the quality and quantity of oocytes. Understanding these mechanisms exhibits the importance of managing chronic inflammation to preserve reproductive health and enhance fertility. By addressing the underlying inflammatory processes, it may be possible to mitigate the adverse effects on ovarian function and improve reproductive outcomes for women.
