An essential property of the immune system is self-regulation. An immune response that is not adequate can lead to immunodeficiency, whereas an immune response that is excessive can lead to conditions from allergic responses to autoimmune diseases. Which of these is not an example of a breakdown of the self-regulation of the immune system? a. Multiple sclerosis b. Huntington disease c. Systemic lupus d. Fibromylagia
