GlossaryAutoantigens

proteins mistakenly attacked by the immune system

Autoantigens are proteins or molecules that are naturally present in the body but are mistakenly targeted by the immune system as if they were harmful invaders. This misidentification can lead to autoimmune diseases, where the body's immune response attacks its own tissues, such as in conditions like alopecia areata, where the immune system targets hair follicles.
