Regulatory T cells (Treg)

Regulatory T cells, or Treg cells, are a specialized type of immune cell that help maintain the body's immune balance. They prevent the immune system from overreacting or attacking the body's own tissues, which can cause autoimmune diseases. Treg cells work by suppressing or controlling the activity of other immune cells, ensuring that immune responses are targeted only at harmful invaders like bacteria or viruses. This regulation is essential for immune system health, preventing excessive inflammation and maintaining tolerance to the body's own cells.
