What is the Origin of Cytokine Hypothesis?

This concept developed from the extensive research into the immune system's signaling network, with the initial discovery and naming of 'cytokines' occurring in the mid-20th century. The hypothesis gained formal traction as evidence accumulated showing that these immune mediators were not restricted to immune responses but actively communicated with the central nervous system and peripheral endocrine glands. This established a critical link between systemic inflammation and homeostatic hormonal balance.

What is the Mechanism of Cytokine Hypothesis?

Pro-inflammatory cytokines, including Interleukin-6 and Tumor Necrosis Factor-alpha, can directly interfere with the synthesis, secretion, and peripheral action of key hormones. For instance, they may inhibit the pulsatile release of pituitary hormones or induce tissue-level resistance to insulin and thyroid hormones, disrupting metabolic homeostasis. This mechanism underscores how a sustained inflammatory state can contribute directly to hormonal decline and the accelerated development of age-related phenotypes.

Cytokine Hypothesis

Meaning

The Cytokine Hypothesis proposes that systemic inflammatory signaling molecules, specifically cytokines, are central mediators in the development and progression of various physiological and pathological states, particularly those involving the neuroendocrine and immune systems. In the context of hormonal health, this theory links chronic, low-grade inflammation to significant hormonal dysregulation, such as the suppression of the thyroid axis or impairment of the hypothalamic-pituitary-adrenal axis. This provides a scientific framework for understanding the profound interplay between immunity and endocrinology.
