In immunology, autoimmunity is the system of immune responses of an organism against its own healthy cells, tissues and other normal body constituents. [1] [2] Any disease resulting from this type of immune response is termed an "autoimmune disease".
Laboratory testing plays a pivotal role in the diagnosis of autoimmune diseases. These tests can identify the presence of certain autoantibodies or other immune markers that indicate a self-directed immune response. Autoantibody testing: Many autoimmune diseases are characterized by the presence of autoantibodies.
The outcome of autoimmune activity is determined by several factors, namely: the intensity, the location, and the duration of the autoimmune response. For an autoimmune response to be beneficial, its intensity, duration and site of activity must be tightly regulated. Although autoimmune T cells exist in all healthy individuals, a relatively ...

Symptoms may include: arthritis-type joint pain, fatigue, fever, rashes, cold or allergy-type symptoms, weight loss, and muscular weakness.

This article provides a list of autoimmune diseases. These conditions, where the body's immune system mistakenly attacks its own cells, affect a range of organs and systems within the body. Each disorder is listed with the primary organ or body part that it affects and the associated autoantibodies that are typically found in people diagnosed ...
Disease experts say it has become increasingly clear that an autoimmune response, in which antibodies attack the body’s own healthy cells and tissue, plays an important role in some long-Covid ...
