regulatory T cells

Regulatory T cells (or Tregs) are a specialized type of immune cell that help keep the immune system balanced. They primarily work to prevent the immune system from attacking the body's own tissues, reducing the risk of autoimmune diseases. Tregs also help modulate immune responses during infections and inflammation, ensuring they are effective but not excessive. By maintaining this balance, Tregs play a critical role in immune system regulation, promoting tolerance, and preventing harmful overreactions while allowing the body to defend against pathogens.
