Immune response regulation

Immune response regulation involves controlling how the immune system reacts to threats like infections or injuries. It ensures the system defends effectively without overreacting, which could harm the body's own tissues. This balance is maintained through signals and cells that activate or suppress immune activities as needed. For example, regulatory cells release substances to calm inflammation once the threat is gone. Proper regulation prevents excessive immune responses, such as allergies or autoimmune diseases, where the body mistakenly attacks itself. Overall, immune regulation keeps defenses strong yet balanced, protecting health while avoiding unnecessary damage.
