Pitiful Posting and the Alphabet Challenge

 

According to the MedlinePlus Medical Encyclopedia (associated with NIH)

an antibody (also known as an immunoglobulin) is a protein produced by the body’s immune system when it detects harmful substances, called antigens.

Each antibody responds to and binds to a particular antigen. They are in the shape of a Y comprised of 4 polypeptides; 2 heavy chains and 2 light chains. Antibodies are produced by B-cells, a type of lymphocyte.

When healthy tissue is mistaken for something harmful and antibodies are produced an autoimmune disease can develop.
