Question 1

What is the Meaning of Interleukin-15?

Accepted Answer

Interleukin-15 (IL-15) is a pleiotropic cytokine primarily known for its role in the innate and adaptive immune systems, particularly in the development, maintenance, and proliferation of natural killer (NK) cells and T cells. Within the hormonal health space, it is also recognized as a myokine, a protein secreted by muscle fibers during contraction. This dual function links muscle activity directly to metabolic and immune regulation.

Question 2

What is the Origin of Interleukin-15?

Accepted Answer

The name follows the nomenclature for "Interleukins," a class of cytokines whose function is to mediate communication between leukocytes (white blood cells). Its specific designation as "15" reflects its order of discovery within this family. Its identification as a myokine is a more recent understanding that bridges the fields of immunology, exercise physiology, and endocrinology.

Question 3

What is the Mechanism of Interleukin-15?

Accepted Answer

IL-15 exerts its cellular effects by binding to a heterotrimeric receptor complex composed of the IL-15Rα, IL-2/15Rβ, and the common gamma chain (γc). This binding activates the critical JAK/STAT signaling pathway, which drives the proliferation and survival of its target lymphocytes. As a myokine, its release from muscle tissue suggests a mechanism for muscle-to-fat and muscle-to-immune communication, potentially influencing body composition by promoting anabolism and fat utilization.
