A) a condition in which B cells and T cells respond independently to antigens and do not interact correctly

Question

Quizplus · Accepted Answer

Autoimmune disease is a condition in which the immune system mistakenly attacks and destroys healthy body tissue because it perceives them as foreign or non-self. This occurs when self molecules are treated as non-self, triggering an immune response against them. Option A is incorrect because it describes a problem with B and T cell interaction, which is not related to autoimmune disease. Option B is incorrect because it describes a problem with adaptive immunity against the same antigen, not an attack on self molecules. Option D is incorrect because it describes the creation of random antibodies without an antigen trigger, which is not related to autoimmune disease.
