In higher vertebrates, the immune system can distinguish self cells and non self. If this property is lost due to genetic abnormality and it attacks self cells, then it leads to: A. Allergic response B. Graft rejection C. Auto immune disease D. Active immunity
Option C. An autoimmune disease is a condition arising from an abnormal immune response to normal body tissue. In an autoimmune disease, the immune system fails to recognize self-cells and produces antibodies against self-cells. Common symptoms include low-grade fever and feeling tired. Autoimmune disease is due to genetic abnormality or other environmental factors.
