Autoimmunity:

Autoimmunity is a kind of immunity response that triggers the immune system to attack the body’s healthy tissues and cells. Diseases resulting from an autoimmunity are called autoimmune diseases. This condition is also characterized by the immune system’s inability to recognize between foreign substances and body’s own cells. Generally, the B cell lymphocyte (a cell that forms in the plasma) produces antibodies to fight foreign substances like bacteria, virus, chemicals, and protozoa. This is an antigen. But, the immune system should be able to distinguish between a foreign substance and an own cell before launching an attack. In autoimmunity, this fails to happen and the immune system damages the organs. This leads to diseases like type 1 diabetes, systemic lupus erythematosus, and many others.
