T regulatory cells

T regulatory cells, or Tregs, are a specialized type of immune cell that help keep the immune system balanced. Their main role is to prevent the immune system from overreacting or attacking the body's own tissues, which can cause autoimmune diseases. They do this by suppressing the activity of other immune cells that might otherwise cause inflammation or damage. Essentially, Tregs act as peacekeepers within the immune system, ensuring it responds appropriately to threats like infections without harming healthy cells. They are vital for maintaining immune tolerance and overall health.
