Functions and Effects of Interleukins

Interleukins (ILs) are a group of cytokines that play a critical role in the immune system. Their primary functions and effects include:

1. Immune regulation: Interleukins act as signaling molecules within the immune system, modulating the activity and function of immune cells—promoting their proliferation and differentiation—and thereby enhancing overall immune competence.

2. Anti-inflammatory effects: Certain interleukins—such as IL-10 and IL-4—exert anti-inflammatory actions, mitigating inflammatory tissue damage and offering therapeutic benefits in inflammatory diseases.

3. Promotion of cell growth and differentiation: Interleukins support cellular growth and differentiation, which is essential for tissue repair and regeneration—particularly during wound healing and fracture repair.
