In the later 19th century, it was believed that the immune system was unable to react against the body's own tissues. Paul Ehrlich, at the turn of the 20th century, proposed the concept of horror autotoxicus. Ehrlich later adjusted his theory to recognize the possibility of autoimmune tissue attacks, but believed certain innate protection ...
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 with the condition. Each disorder is also categorized ...
The technology can uniquely identify a person by analyzing the antibodies in body fluids. A unique, individual set of antibodies, called individual specific autoantibodies (ISA), is found in blood, serum, saliva, urine, semen, perspiration, tears, and body tissues, and the antibodies are not affected by illness, medication, or food/drug intake.
These shared symptoms occur as a result of the body's immune system mistakenly attacking its own cells and tissues, causing inflammation and damage. However, due to the broad range of autoimmune diseases, the specific presentation of symptoms can significantly vary based on the type of disease, the organ systems affected, and individual factors ...
Autoimmune hemolytic anemia (AIHA) is an autoimmune disorder which occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst , leading to an insufficient number of oxygen-carrying red blood cells in circulation . The lifetime of the RBCs is reduced from the normal 100–120 days to just a few days in ...
Lupus, formally called systemic lupus erythematosus (SLE), is an autoimmune disease in which the body's immune system mistakenly attacks healthy tissue in many parts of the body. [1] Symptoms vary among people and may be mild to severe. [1]
The immune system is a network of cells, molecules, and organs that function to protect the body from any form of harm. In autoimmune diseases like autoimmune retinopathy (AIR), the immune system attacks the body’s own tissues and cells. In AIR, the retina, a highly specialized tissue, becomes the target of this misdirected immune response ...
Hypersensitivity (also called hypersensitivity reaction or intolerance) is an abnormal physiological condition in which there is an undesirable and adverse immune response to an antigen. [ 1 ] [ 2 ] It is an abnormality in the immune system that causes immune diseases including allergies and autoimmunity .
