IMMUNOLOGY

Detailed explanation-1: -Classes of immunoglobulins. The five primary classes of immunoglobulins are IgG, IgM, IgA, IgD, and IgE. These are distinguished by the type of heavy chain found in the molecule.

Detailed explanation-2: -There are 5 types of heavy chain constant regions in antibodies (immunoglobulin) and according to these types, they are classified into IgG, IgM, IgA, IgD, and IgE. They are distributed and function differently in the body.

Detailed explanation-3: -Listen to pronunciation. (IH-myoo-noh-GLAH-byoo-lin) A protein that is made by B cells and plasma cells (types of white blood cells) and helps the body fight infection.

Detailed explanation-4: -Immunoglobulins, or antibodies, are Y-shaped proteins made by specialized cells of the immune system called B cells and plasma cells. The immune system makes antibodies that are specific for each disease-causing agent and can learn to make specific antibodies to a new virus.

Detailed explanation-5: -Immunoglobulins (Ig) or antibodies are glycoproteins produced by plasma cells. B cells are instructed by specific immunogens, for example, bacterial proteins, to differentiate into plasma cells.

Detailed explanation-6: -Immunoglobulin A (IgA): It’s found in the linings of the respiratory tract and digestive system, as well as in saliva (spit), tears, and breast milk. Immunoglobulin G (IgG): This is the most common antibody. It’s in blood and other body fluids, and protects against bacterial and viral infections.
