View source for Hyperimmune globulin

'''Hyperimmune globulin''' (pronunciation: hi-per-im-yoon glo-bu-lin) is a type of [[immunoglobulin]] (Ig) that is produced in response to a specific [[antigen]] or [[pathogen]]. It is a concentrated solution of [[antibodies]], which are proteins that the immune system uses to fight off infections.

==Etymology==
The term "hyperimmune" is derived from the Greek words "hyper" meaning "over" or "above" and "immune" meaning "exempt", in this context, it refers to an enhanced immune response. "Globulin" is derived from the Latin word "globus" meaning "sphere", referring to the globular shape of these proteins.

==Production==
Hyperimmune globulins are produced by injecting a specific antigen into an animal (usually a horse or rabbit). The animal's immune system responds by producing a high concentration of specific antibodies against the antigen. The animal's blood is then collected, and the serum is separated and purified to produce the hyperimmune globulin.

==Uses==
Hyperimmune globulins are used in medicine to provide passive immunity to individuals who are at risk of, or have been exposed to, certain infectious diseases. They are used in the treatment of diseases such as [[hepatitis B]], [[rabies]], [[tetanus]], and [[chickenpox]]. Hyperimmune globulins are also used in the treatment of some autoimmune diseases, such as [[Guillain-Barré syndrome]] and [[Kawasaki disease]].
