Immune Globulin

Immune globulin (pronounced: ih-MYOON GLOB-yoo-lin), also known as Immunoglobulin, is a type of protein produced by plasma cells and lymphocytes. It plays a crucial role in the body's immune system, helping to protect against infections.

Etymology

The term "immune globulin" is derived from the Latin word "immunis" meaning exempt or protected, and the Latin word "globulus" meaning small sphere. This refers to the protein's role in protecting the body from diseases.

Immune globulin is responsible for identifying and neutralizing foreign objects such as bacteria and viruses. There are five classes of immune globulins, each with a different role in the immune response: IgG, IgA, IgM, IgD, and IgE.
