BAFF (B-cell activating factor)

BAFF (B-cell activating factor) is a protein that helps regulate immune system function by supporting the development, survival, and activity of B cells—white blood cells responsible for producing antibodies. It is essential for a healthy immune response, ensuring the body can identify and fight infections. However, if BAFF levels become too high, it can cause the immune system to become overactive, leading to autoimmune diseases where the body attacks its own tissues. Scientists study BAFF to better understand these conditions and develop targeted treatments to balance immune activity effectively.
