cytokine theory

Cytokine theory explains how certain signaling proteins, called cytokines, play a crucial role in the immune system and communication between cells. When the body is challenged by infections or diseases, cytokines help coordinate the immune response by signaling cells to act, grow, or differentiate. However, an imbalance in cytokine production can lead to excessive inflammation or insufficient immune response, contributing to various health issues, including autoimmune diseases and chronic illnesses. Understanding cytokines can help researchers develop new treatments by targeting these signals to restore balance in the immune system.
