Question

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:

Options

• Graft rejection

• Auto-immune disease

• Activate immunity

• Allergic response

Answer 1

Auto-immune disease

Explanation:

Auto-immune disease occurs when immune cells are unable to distinguish between self and non-self cells and attack self-cells, resulting in auto-immune disorders such as interstitial lung disease in humans.
