← Life Sciences & MedicineWhat causes increased inflammation and tissue damage in autoimmune diseases?
A)Reduced antibody isotype switching events
B)Self-reactive lymphocytes escaping immune tolerance✓
C)Enhanced regulatory T cell activity
D)Decreased antigen presentation on MHC-II
💡 Explanation
Autoimmune diseases arise because self-reactive lymphocytes, which should have been eliminated through central and peripheral tolerance mechanisms, escape these controls and attack the body's own tissues. This leads to chronic inflammation and damage rather than immune homeostasis because these lymphocytes recognize self-antigens, rather than foreign pathogens, triggering an immune response.
