Autoantibodies are probably involved in:
grandymaker [24]

Answer:

systemic lupus erythematosus

Explanation:

Systemic lupus erythematosus (SLE or just lupus) is a chronic inflammatory disease of autoimmune origin, the symptoms of which may appear in various organs slowly and progressively (in months) or more rapidly (in weeks) and vary with phases of activity and remission. Because it is a disease of the immune system, which is responsible for producing antibodies and organizing inflammation mechanisms in all organs, when a person has SLE they may have different types symptoms and various body locations. Some symptoms are general such as fever, weight loss, loss of appetite, weakness and discouragement. Others, specific to each organ such as joint pain, skin blemishes, pleural inflammation, hypertension, and / or kidney problems.

The main cause of this disease is the imbalance in the production of antibodies that react with proteins in the body itself and cause inflammation in various organs such as the skin, mucous membranes, pleura and lungs, joints, kidneys, etc.). Thus, we understand that the type of symptom a person develops depends on the type of autoantibody the person has, and that as the development of each antibody relates to the genetic characteristics of each person, each person with lupus tends to have clinical manifestations. specific and very personal (symptoms).

Autoantibodies are antibodies directed to the body's own cells and tissues. Normally, the immune system differentiates the body's own proteins from foreign proteins, forming antibodies only against those identified as potentially dangerous.
