autoimmune
UK: ˌɔːtəʊɪˈmjuːn | US: ˌɔːtoʊɪˈmjuːn
adj. relating to or caused by antibodies or lymphocytes produced against substances naturally present in the body (self-antigens).
The word "autoimmune" combines "auto-" (from Greek autos, meaning "self") and "immune" (from Latin immunis, meaning "exempt" or "protected"). The term emerged in the mid-20th century to describe conditions where the immune system mistakenly attacks the body's own tissues. The logic reflects a paradox: the immune system, designed for protection, becomes self-destructive.
