"regulatory T cell"的定义和意义

What is a "regulatory T cell"?

A regulatory T cell, or Treg, is a specialized type of T cell that contributes to immune regulation and prevents excessive immune responses in the human body. They play a crucial role in maintaining immune tolerance and preventing excessive immune responses. Tregs suppress the activity of other immune cells, such as effector T cells and B cells, to prevent immune system overactivity and minimize the risk of autoimmune diseases. Their ability to regulate immune responses ensures a balanced and controlled immune system function.
