ANATOMY

Detailed explanation-1: -antibody, also called immunoglobulin, a protective protein produced by the immune system in response to the presence of a foreign substance, called an antigen. Antibodies recognize and latch onto antigens in order to remove them from the body.

Detailed explanation-2: -Also known as antinuclear antibodies (ANAs), autoantibodies target normal proteins in a cell’s nucleus. Autoantibodies mistake normal, healthy proteins as dangerous and unwanted. As a result, your body begins attacking itself. Most people have small amounts of autoantibodies.

Detailed explanation-3: -Antibodies that cause harm Antibodies that recognise the body’s own proteins, instead of proteins from infectious microbes, can cause harm. In autoimmune diseases, such as lupus, multiple sclerosis and rheumatoid arthritis, people produce antibodies that stick to their body’s own proteins and attack healthy cells.

Detailed explanation-4: -Lymphocyte The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body’s own cells that have themselves been taken over by viruses or become cancerous.
