Question

Quizplus · Accepted Answer

Autoimmune disorders occur when the body's immune system recognizes its own cells or tissues as foreign and attacks them. This can happen when a nonself antigen, such as a virus or bacteria, resembles the body's own antigens, triggering an immune response against both the foreign antigen and the body's own cells that have similar antigens. This is known as molecular mimicry and is a common mechanism for the development of autoimmune disorders. Options A, B, and D are incorrect as they do not explain how autoimmune disorders arise.
