Autoimmunity refers to the body’s immune system directing attacks against its own healthy cells.
These are some of the common features observed in autoimmune diseases:
- Genetic predisposition associated with HLA (human leukocyte antigen)
- Measurable autoantibody levels
- Onset in young adulthood or middle age
- Increased susceptibility among females of child-bearing age
- Fluctuations in severity of symptoms ranging from flare-ups to remissions
- Immunosuppressive treatments elicit a positive response
