Question

Quizplus · Accepted Answer

An autoimmune disorder can arise if a nonself antigen coincidentally resembles a self antigen. Normally, the immune system recognizes self-antigens and avoids attacking them. However, in some cases, nonself antigens may bear similarities to self-antigens, which causes the immune system to mistakenly attack self-tissues or self-cells, leading to autoimmune disorders.
