True

Explanation:

Immune disorders are diseases caused by inadequate immune reactions against the body itself. The immune system no longer recognizes one or more body components as its own and produces autoantibodies, antibodies that attack the body's own cells, tissues or organs, causing inflammation and lesions characteristic of these disorders. This type of disturbance results from both underactive and overactive immune systems.
