Autoimmune systemic diseases damage body tissues as the result of:
Answer Choices:
Correct Answer:
an interruption in immune system's self-tolerance to antigens
Rationale:
✨ Autoimmune systemic diseases occur when the immune system fails to recognize self from non-self, leading it to attack the body’s own tissues.
✨ Normally, the immune system has mechanisms of self-tolerance that prevent antibodies and T-cells from targeting the body’s own cells.
✨ When this tolerance is interrupted, autoantibodies and autoreactive T-cells cause chronic inflammation and tissue destruction, as seen in systemic lupus erythematosus (SLE), rheumatoid arthritis, and multiple sclerosis.
✨ This process differs from allergies (overreaction to external allergens) and viral infections like HIV (which destroy CD4 T-lymphocytes).
