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 ...
This is a list of [[White blood cell|immune cell], also known as white blood cells, white cells, leukocytes, or leucocytes. They are cells involved in protecting the body against both infectious disease and foreign invaders .
An autoimmune disease is a condition arising from an abnormal immune response to a normal body part. [5] There are at least 80 types of autoimmune diseases. [5] Nearly any body part can be involved. Common symptoms include low-grade fever and feeling tired. [5] Often symptoms come and go. [5]
However, some autoimmune diseases may present with more specific symptoms such as joint pain, skin rashes (e.g., urticaria), or neurological symptoms. The exact causes of autoimmune diseases remain unclear and are likely multifactorial, involving both genetic and environmental influences. [7]
Several rare conditions are due to defects in the innate immune system, which is a basic line of defense that is independent of the more advanced lymphocyte-related systems. Many of these conditions are associated with skin problems. [7] Interleukin 12 receptor, beta 1 deficiency; IL-12p40 deficiency; Interferon gamma receptor 1 deficiency
Overactive immune responses form the other end of immune dysfunction, particularly the autoimmune diseases. Here, the immune system fails to properly distinguish between self and non-self, and attacks part of the body. Under normal circumstances, many T cells and antibodies react with "self" peptides.

Aplastic anemia is a condition where bone marrow does not produce sufficient new cells to replenish blood cells. [27] Autoimmune hemolytic anemia: D59.0-D59.1: Autoimmune hemolytic anemia (AIHA) is a type of hemolytic anemia where the body's immune system attacks its own red blood cells (RBCs), leading to their destruction .
Certain chemical agents and drugs can also be associated with the genesis of autoimmune conditions, or conditions that simulate autoimmune diseases. The most striking of these is the drug-induced lupus erythematosus. Usually, withdrawal of the offending drug cures the symptoms in a patient.
